he light, warm rain in Hong Kong was refreshingafter 15 hours on the plane. The next step was toGuangzhou in the People's Republic of China. I

especially looked forward to visiting Professor XuHonghua who had helped us design a new garden of tra-ditional Chinese herbs in 1987. But I found no train ticketreserved in my name as planned and was told that fewtickets were available due to the upcoming Mid-AutumnFestival. Suddenly the reality of traveling in Chinabecame apparent. Throughout the next five weeks themain challenge would be getting tickets at each stop onthe itinerary because they can only be purchased in eachcity in turn. This left me with a sense of uncertainty,which proved to be the only constant in the journey.

In Guangzhou I was warmly welcomed by my hostProfessor Xu. We had much to tell each other, but at thispoint we only had one day together. In the followingweeks I would attend the International Symposium ofBotanical Gardens in Nanjing, travel to several other bo-tanical gardens, and spend a week at the GuangzhouCollege of Traditional Chinese Medicine where Professor

Latest Chinese Exchange a SuccessXu teaches pharmacology. Here under his guidance Iwould research Chinese medicinal plants. The trip wasmade possible by an exchange between the GuangzhouCollege and the American College of Traditional ChineseMedicine in San Francisco, and assistance from theFriends of the U.C. Botanical Garden.

International Exchange of IdeasThe Symposium at Nanjing on September 24-28

drew 258 participants from 42 gardens in China and 22other countries. The event was jointly organized by HeShan-an, Director of Nanjing Botanical Garden MemorialSun Yat-sen, the Jiangsu Institute of Botany, and over 30botanical gardens in China. Representatives attendedfrom such organizations as International Union for theConservation of Nature and Natural Resources, Interna-tional Association of Botanical Gardens, and WorldWildlife Fund. I was one of 17 delegates from the UnitedStates representing major botanical gardens and universi-ties. Topics included Conservation and Plant Ecology,Taxonomy, Phytochemistry, Plant Introduction andBreeding, Landscape Architecture, and Education.

During the opening ceremony a repeating themewas facilitating cooperation between gardens on theinternational level. For example, Professor KunioIwatsuki from the University of Tokyo is currentlydeveloping a regional program of temperate and tropicalgardens to facilitate inter-garden communication. An-other key theme was the role of botanical gardens inplant conservation. Many people are unaware that thetropical rainforest in southeast Asia is as threatened asthat in Central and South America; this conferencemarked an important effort to address this problem.

A partial conservation solution is to develop strate-gies for ex situ conservation of rare and endangeredspecies within botanical gardens. In February 1987, Chinapublished a list of 389 rare and endangered species and isnow working on a list of 1200 species. Ten percent of theflora of China is known only from type collections; manyspecies are threatened or already extinct, and most of theendangered taxa are monotypic and endemic. Anotherapproach to conservation is to establish nature reserves.There are now 392 in existence in China, covering a totalof 24,500,000 hectares. The main management problems

are the sale of wild plants and the illegal cutting of timber;both need substantial education efforts by the governmentto reduce the impact on natural habitats.

At a conference session on Medicinal and EconomicPlants, I learned about some of the earliest known medici-nal plants and their economic uses. For instance, in LijiangI saw people wearing raincoats made from the fibers of theWindmill Palm (Trachycarpus fortunei). Another speakerreported on cell culture of Panax ginseng being conductedat the College of Traditional Pharmacy in Nanjing. Later atthe Guangzhou College I observed sophisticated equip-ment for analyzing active chemical components of medici-nal plants. Many plants which are mainstays in traditionalmedicine do not have the correct chemical balance whenraised in cultivation and now are being depleted in thewild due to increasing demand. This kind of research is anexciting integration of the age-old Chinese art of healingwith modern technological methods.

Medicinal Plant GardensFollowing the Symposium, I visited medicinal gar-

dens throughout China. Only the Guangzhou College hadthe plants displayed by medicinal function as they are atthe U.C. Botanical Garden. At both Hangzhou and WuhanBotanical Gardens the plants are arranged according tocultural requirements; in the Shanghai Garden they arelaid out taxonomically. In Kunming, Guangzhou, and thesouth China Botanical Garden plants are mostly grownand displayed in containers. The Hangzhou BotanicalGarden has the most extensive collection including a largeshady section with pools and rockeries covered with moss.(Lycopodium serratum and several species of Selaginella areused medicinally.)

At the College at Guangzhou I was impressed to seethe entire grounds landscaped with medicinal plants.They even have a section of plants used in AIDS research.Here I visited the library, research laboratory, andhospital. Professor Xu's wife, Lin Shi-shu, who works inthe pediatric clinic, has studied both Western and Chi-nese traditional medicine for eight years. This is now be-coming common among modern Chinese practitioners.

In Chinese medicine the most fundamental prin-ciples are yin and yang; these are also key elements inclassical Chinese landscape architecture and correspondwith water and stone respectively. In Shanghai I had theopportunity to see a newly completed garden designed inthis classic style. Called Da Guan Yuan, it is based on thefamous Qing Dynasty novel, A Dream of Red Mansions,originally The Tale of the Rock. This classical garden andothers exemplify the ancient principles of Chinesemedicine practiced today as a living tradition.

During the trip I accumulated extensive notes forfuture plantings and collecting expeditions. But some ofmy most enjoyable moments were spent in the Xu'sfamily kitchen with Professor Xu, his wife, mother, andtwo sons. At meals we practiced "Dinner Table Botany,"classifying the plant material in the soup. Professor Xuwas a generous host and kept my room well stocked withtea and mooncakes. His attention to detail and his helpon many occasions made my trip a pleasure. The re-newed contact with Professor Xu and other botanists waswell-timed, continuing a long tradition of successfulexchange between the U.C. Botanical Garden and China.

trigger mechanismof Stylidium graminifolium

Winter 1989

Triggerplantshen I show visitors the marvellous assortment ofgardening and botanical books available in theVisitor Center, I seek out a small book entitled

Triggerplants by Rica Erickson (University of WesternAustralia Press, 1981) commenting "we even stock un-usual titles like this one."

Triggerplants are members of the family Stylidi-aceae, a group restricted to the southern hemisphere,mostly Australia. The common name derives from acurious pollination mechanism: the trigger is the style,which is cloaked by fused stamen filaments so that theanthers appear to be born at the tip of the style. When aninsect visits the flower, it trips a mechanism that causesthe trigger to snap downward and release a load ofpollen on its back. Once a flower has shed its pollen, thestigma emerges from among the spent anthers andstrikes the next insect visitor, picking up pollen from itsbody, thus accomplishing cross-pollination. Apparentlythe repeated blows to the pollinators' backs are not asufficient nuisance to dissuade them from continuing tovisit plants for nectar. Australian children amuse them-selves by tripping the triggers of triggerplants. However,since the triggers reset themselves, these practicesprobably do little if any harm to the flower, despite theauthor's admonition that this floral mechanism "is notdesigned for human amusement".

Two Diverse GeneraThe Western Australian Triggerplants

are mostly members of the genus Stylidium,ranging in size from diminuitive winterannuals to subshrubs. Many of these havevery attractive flowers; a few can be seenin the Botanical Garden. A related genusin Western Australia is Levenhookia, whichErickson calls Styleworts. This small

genus is named after Antony vanLeeuwenhoek, a Dutch cloth merchant

who never visited Australia, never saw astylewort, but whose hobby was makingmagnifying glasses and introducing 17th andearly 18th century biologists to the micro-scopic wonders of living beings. Stylewortspresent a greater menu of pollination mecha-nisms than do Triggerplants, and some ofthese are self-pollinated, though cross-polli-nation appears to be the ancestral rule.

I first encountered Triggerplants andStyleworts in 1983 when I travelled toPerth, Western Australia to study thereproductive behavior of Villarsia, a semi-aquatic and very attractive genus ofplants that happened not to be inflower when I arrived. I decided topass time by studying the plant life on

Stylidium asteroideum

the granite outcrops that dot Western Australia. Thesegranite outcrops appealed to me because they havevernal pools, which made me feel at home. The plantsthere are mostly small and mostly annual, so they areeasily collected and dried. And there are no shrubs ortrees on these outcrops, so pests such as bull ants andticks are not a problem. If tiger snakes venture out ontothese rocks, they are easily seen, even by a botanist. Theyare not so easily seen in the bush.

Both genera of Stylidiaceae grow in abundance onthese outcrops; I found two species of Stylidium and nineof Levenhookia. Because the species often grow in mixedcolonies and look very much alike, I drew sketches of theflowers in my field book, noting stripes and other colorpatterns. Then when the time came to identify my two-dimensional, faded dried specimens I could reconstructthe intricacy and beauty of the tiny flowers.

Erickson's little book makes delightful reading, evenfor those who may never see these fascinating plants inthe field. Her book can be used to identify triggerplantsshould one ever visit Australia, but there's more in it thatthat. Her drawings and watercolors of the plants areattractive. There are lyrical descriptions of the WesternAustralian countryside and of various Triggerplants thathave especially caught her interest. She has coinedcommon names for many of the 136 species she discussesincluding one she calls "Cowkicks". In a charming asideshe explains how she learned of this curious name:

"Lens and watch in hand I crouched beside atriggerplant...preparing to time the repoising of the triggercolumn. A child stood soberly beside me watching as I probedthe throat of the flower to make the trigger shoot over. 'Packs afair punch for a flower,' he said. 'We call them Cowkicks. Didyou know?'"

She didn't and you won't either, unless you take alook at this book — that is, providing it is still on theshelf.

GARDEN SPOTLIGHT

Cacti of the High Desert Sun

T he cactus collection has been one of the Garden'smost popular features for decades. Although notthe largest outdoor assemblage of cacti in the

world, it is an outstanding selection of unusual plants,including many found nowhere else in cultivation. Asproof of their surprising adaptability, all these cacti havehad to survive our cool wet winters, conditions generallyconsidered anathema to desert plants. The long estab-lished plantings in the New World Desert area, incombination with the more recent Mexican section cactusassociates, complements the equally comprehensiveindoor collection in the Desert Greenhouse.

History of the CollectionSome of the cacti in the collection outdate the

present site of the Garden. In 1932, when James Westestablished a rock garden at the then four year oldBotanical Garden location, he transplanted some cactusspecimens from the main campus where they had beengrowing for a number of years. The director of theGarden, Dr. T.H. Goodspeed, was an ardent supporter ofthe succulent and cactus collection and encouraged itsexpansion.

The present collection started taking shape in the1930s after an expedition to South America, the first in aseries of collecting trips that continued for 30 years.These expeditions, under the leadership of West and laterPaul Hutchison, introduced many species new to science.The later expeditions to Peru and Chile focused intereston the previously unknown cacti of the Chilean deserts,leading ultimately to their widespread cultivation.

Recently Jim Affolter, Kurt Zadnik, and I travelled toBaja California and the American Southwest on a numberof shorter expeditions, sharing information and plantmaterial with local botanical institutions. Now, plans areafoot to establish experimental plantings from areaspreviously thought too climatically different fromBerkeley for success. Already some plants from BajaCalifornia have survived the last two winters in theground in good health, though they have not yet beentested by a really wet or cold winter. Over the years anumber of plants from South America have been lost, butmany others have proven perfectly hardy in our climate.

The New World Desert OutdoorsThe struggle for survival under adverse circum-

stances has molded almost everything about cacti: theirdevelopment of spines and water-retaining tissue, andeven their striking shapes. Yet constrained as they are bythe confines of harsh environments, cacti have devel-oped endless variations on a few basic themes. Thisvariability may be the most interesting thing about them.The plants in the outdoor collection embody almost all ofthe forms cacti attain. Here then, are some plants thatmay catch your eye during a walk through the cactusgarden.

From over 13,000 feet in the Peruvian and BolivianAndes come several species of columnar Espostoas andothers now known as Borzicactus (once called Oreocereus).In this region temperatures can vary an astonishing onehundred degrees during a single day, from belowfreezing at night to over 100°F during the day. Here thewooly coverings on the column not only protect the

Winter 1989 Page 5

cactus from the cold and occasional snow, they also trapmoisture. As the dew condenses on the wool and runsdown the stems, the plants are supplied with extra watervital to survival in the high arid habitat. Some Cleistocac-tus, mostly from Argentina, are densely covered —notwith wool but with thin, glassy, white spines. If you walkthrough the New World Desert early in the morning, youmay see these cacti completely covered by sparklingdrops of dew that will soon drip down to their thirstyroots.

Some of the largest cacti in the garden are variousspecies of Trichocereus, a mostly Peruvian genus. The tallTrichocereus terscheckii has been growing beside the mainstairway in the New World Desert for over 30 years.Notice its spines: those along the lower part of the plant'sstem are long, sharp, and menacing, while higher up theyare noticeably shorter and less threatening. Many colum-nar cacti produce fiercely protective spines in their vul-nerable youth. When after many years, they growbeyond the reach of browsing predators, their lofty newgrowth doesn't require the protection needed closer tothe ground. Other Trichocereus in the Garden are muchsmaller plants, no more than a foot tall, arranged indense clusters, a configuration that minimizes theamount of surface area exposed to the elements. AllTrichocereus are notable for their large white flowers inlate spring and summer.

Many of the more interesting cacti are barrel cactigrowing as solitary, stout, ribbed cylinders. These plantsswell and shrink in accordion fashion depending on theirwater content. The most familiar barrel cacti are thosefrom the Southwestern deserts, from Palm Springs east toTexas. Though a majority of our outdoor cacti are SouthAmerican, we have a number of Golden Barrels (Echi-nocactus grusonii) from Mexico, a popular and widelygrown cactus valued for its bold geometric shape andprominent yellow spines. Tucked away in more shelteredparts of the New World Desert are several Neoporteriasand Copiapoas from the very arid lands of northernChile — rare plants often considered much too suscep-tible to rot for planting outdoors. Our plants, however,have survived for many years in good health, producingpink and yellow flowers year after year. Mixed in with allthe other forms of cacti are many Opuntias, the pricklypears, known for their tasty and colorful fruits.

The Greenhouse CollectionInside the controlled climate of the Desert Green-

house we grow a number of more sensitive cacti withMexican species the most significant part of this collec-tion. Although beneficial, the extra heat obtained fromgrowing under glass isn't the main reason for keepingthese plants indoors. In fact, many of them live at highelevations where they endure severe cold. These cacti,

however, must remain very dry in winter, making theircultivation outdoors impossible.

The genus Mammillaria with well over a hundredmostly Mexican species encompasses a tremendousrange of size, shape, and spination patterns. Also grow-ing under glass are some of the most bizarre cacti —hard, sometimes spineless Ariocarpus, Pelecyphora, andTurbinicarpus that resemble rocks or perhaps somepeculiar variety of underwater coral. Anyone who hasseen these plants growing in chunks of pure limestone inextraordinarily desolate circumstances can only marvel attheir existence, and indeed they survive where almostnothing else can.

A Garden for the PublicThe cactus garden is laid out in more or less geo-

graphically associated groupings, allowing for considera-tions of cultivation. Future areas of interest include theBaja California fog desert and the high arid lands of theGreat Basin. Many cacti from the Great Basin such asPediocactus and Sclerocactus have stringent, poorlyunderstood environmental requirements that severelyrestrict their range. As a result the survival of thesespecies is threatened by increasing commercial develop-ment of the region. Some species have been collectedalmost out of existence.

Able to survive under the most arduous circum-stances, with lustrous flowers that belie their armoredappearance, cactus plants have intrigued people sinceColumbus first brought some back to Spain. The collec-tion here at the Botanical Garden provides an unequalledopportunity to see and learn about some of the rarest ofthese plants. Whatever the future holds in store for theBotanical Garden, we can be sure that cacti will remain amajor part of its total picture.
