Transcript of Araceae

Description Araceae is a family of monocotyledonous

flowering plants The family also goes by the name of Arum

family and species in this family are often colloquially known as aroids

Many plants in this family are thermogenic (heat-producing).

1. to attract insects (usually beetles) to pollinate the plant

2. to prevent tissue damage in cold regions

4.Kingdom: PlantaeOrder: AlismatalesFamily: AraceaeSubfamily: MonsteroideaeTribe: MonstereaeGenus: EpipremnumSpecies: E. aureum

Binomial name : Epipremnum aureumLocal Name : The Devil’s Ivy, Silver

Vine, Money Plant, Centipede tongavine and Solomon Islands' Ivy

Malay name : Kelampayang Besar  / Pokok Duit

Size : 1000 cm commonly known as Pothos

(once classified under the genus Pothos), Silver Vine, and Devil's Ivy is an aroid native to southeastern Asia (Malaysia, Indonesia) and New Guinea. It is sometimes mistakenly called philodendron at plant stores.

Brief DescriptionIt is a liana growing to 20 m tall, with stems up to

4 cm diameter, climbing by means of aerial roots which hook over tree branches.

Leaves : evergreen, alternate, heart-shaped, entire on juvenile plants, but irregularly pinnatifid (comb like arrangement of parts ,arising from one side of an axis)

Flowers : produced in a spathe up to 23 cm long. This plant produces trailing stems when it climbs up trees and these take root when they reach the ground and grow along it. The leaves on these trailing stems grow up to 10cm long and are the one normally seen is this plant when it is cultivated as a pot plant.

Continue.....A climbing plant that

climbs with the help of aerial and clasping roots

The plant can become large depending on growing conditions

It can survive in low light conditions like florescent lights, and basements.

USESIt is a popular houseplant with numerous

cultivars selected for leaves with white, yellow, or light green variegation. It is often used in decorative displays in shopping centres, offices, and other public locations largely because it is a very hardy plant that requires little care and is also attractively leafy.

It is also efficient at removing indoor pollutants such as formaldehyde, xylene, and benzene.

Other names include Centipede tongavine and Devil's Ivy. It is also popularly known as "money plant" in certain parts of the world (particularly in India).

5.The red caladiumOriginated from the

tropical regions of South America.

All or parts of the caladium plant may be poisonous

Contact with sap may irritate skin

Malay name : Keladi merah

Scientific name : Caladium bicolour

Size : 45cmOther Names : Red

Caladium, elephant ear

UsesSeveral species are grown as ornamental plants

for their large, arrowhead-shaped leaves marked in varying patterns in white, pink, and red and have been in cultivation in Europe since the late 1700s.

The two forms most widely cultivated are called "fancy-leaved" and "lance-leaved". Most Caladiums in cultivation grow to about 24 inches (60 cm) high and 24 inches (60 cm) wide, although dwarf varieties are now in cultivation

All parts of the plant are poisonous. They should not be ingested and may irritate sensitive skin.

Caladiums are used in shady beds and borders.

They often are planted along the north or east side of a building or wall. Caladiums are striking in dense plantings.

They provide warm colour in areas too shady for most flowers. Use caladiums to provide some colour amongst lacy ferns and stately gingers. Caladium leaves will last for several days in fresh flower arrangements.

6.Giant YamCan grow to be a two

meter giant plant, common near limestone outcrops and abandoned grounds

Often planted as a decorative leafy plant because of its beautiful heart shaped foliage.

Malay name : Keladi Gajah / Birah

Scientific name : Colocasia gigantea   / Alocasia macrorrhiza (L.) Schott

Size : 200 cmOther name : Giant

Yam / Ape Plant,Giant Elephant Ear

7.Yam / TaroTropical plant grown

primarily as a vegetable food for its edible corm, and secondarily as a leaf vegetable.

It is considered a staple in oceanic cultures

It is sometimes loosely called elephant ear

Taro leaves are rich in vitamins and minerals. They are a good source of thiamine,

riboflavin, iron, phosphorus, and zinc, and a very good source of vitamin B6, vitamin C, niacin, potassium, copper, and manganese.

Taro corms are very high in starch, and are a good source of dietary fiber.

Malay name : (Pokok) Ubi Keladi

Scientific name : Colocasia esculenta

Size : 60cmOther names :

Yam / Taro, eddo, and dasheen

The Dumb CaneA large herbaceous

plant that can reach the height of 1 meter.

The sap of the plant is caustic.

Temperatures below about 5˚C (40˚F) can kill the plant.

The cells of the plant contain needle-shaped calcium oxalate crystals called raphides

If a leaf is chewed, these crystals can cause a temporary burning sensation and erythema. (may include temporary numbness of the tongue and vocal cords)

Malay name : Dieffenbachia Putih Kehijauan  / Batang Bisu

Scientific name : Dieffenbachia maculata

Size : 100cmOther name : The

Dumb Cane

Black Kris yamAn average size yam plant, and is from the Philippines

The Kris plant is grown for the very attractive foliage.

It needs warm, humid, shady conditions and plenty of water during the summer

Malay name : Keladi Keris Hitam  / Pokok Senteh Keris Hitam

Scientific name : Alocasia sanderiana Bull.

Size : 50 cmOther name : Black

Kris yam

Corpse FlowerAmorphophallus Paeoniifolius (Campanulatum)

The family is characterised by its inflorescence, consisting of a fleshy spike of small flowers (spadix) usually subtended by a large bract (spathe).

Produces a single inflorescence followed by a solitary leaf.

Only blooms when mature.

Flowers last only about 5 days.

The fresh inflorescence emits a stink odour reminiscent of rotting flesh to attract pollinating

The foul odour only last for a few hours after the flower opens.

The corms of some varieties are edible and grown as food crops in several Asian countries, especially Indonesia.

It grows in wild form in the Philippines, Malaysia, Indonesia, and other Southeast Asian countries.

A group I intron has recently been shown to have invaded mitochondrial cox1 genes by horizontal transfer many times during the broad course of angiosperm evolution.

To investigate the frequency of acquisition of this intron within a more closely related group of plants, they determined its distribution and inferred its evolutionary history among 14 genera of the monocot family Araceae.
