I can't imagine that ‘Red listing’

makes me so tired !!!

No, we don’t think

so !!!

Let me say!!!

(BGCI)

Have you finished to access that

species?

I don’t like you mention on

‘threatened species’ during eating!

What is Magnoliaceae?

� Magnoliidae: Magnoliales: Magnoliaceae

� 2 (17!) genera: more than 300 species

� Mainly in SE Asia and in Central America, E and S North America, including Mexico and Antilles, and N South America

� Many ornamentals and timbers

• Stipules present => annual scars

Characters of:

Flowers

• Inflorescence: solitary

• Flowers: most perfect, flowering bract, 3-merous, actinomorphic.

• Tepals (not sepal and petal).

Androecium: numerous spirally arranged stamens

Gynoecium: many simple carpels spirally arranged on an elongated receptacle (superior).

Gynophore

Stamens: anthers

Laterally dehiscent

Extrorsely dehiscent

Introrsely dehiscent

Magnolia-type: spherical, ovoid, ellipsoid (Magnolia, Manglietia, Kmeria, Parakmeria etc.)

Michelia-type: cylindrical

Fruits: aggregate of follices

Some irregularly dehiscent berrylike structure or samaras

Archaeanthus linnenbergeri one of the earliest groups of the flowering plants in Angiosperms

Fossilized specimens datting back over 100 million years are thought to be ancestors of existing Magnolias

Taxonomy of Magnoliaceae in Vietnam

• South-East Asia, Indochinese Peninsula

• 331. 698 Km2;

• 90,549,390 in Population;

• 54 Ethnic groups - Northern: 4 different seasons

- Southern: tropical monsoon: dry and rainy, 27.50C, without winter

� Tropical and temperate zone with a strong monsoon influence � Sunny days, high rate of rainfall (1, 500 to 2, 000 mm) and humidity (80%) � t0/year: 22-27, 3 types of climate area
