Madagascar plants
are probably even more unique than Madagascar
animals.
Out of the 12,000
plant species on
the
island about 80% are endemic.
Baobab
Trees Six of
the
world's eight baobab tree species are endemic to Madagascar. These
include Za Baobab (Adansonia
za),
Suarez Baobab (Adansonia
suarezensis),
Fony Baobab (Adansonia
rubrostipa),
Perrier's Baobab (Adansonia
perrieri),
Madagascar Baobab (Adansonia
madagascariensis) and Grandidier's Baobab (Adansonia grandidieri).
The other
two - African Baobab (Adansonia
digitata) and Boab (Adansonia
gregorii)
are found in Africa and Australia respectively. Baobabs can grow huge
(up to 15m in diametre) and old (some are thought to be thousands of
years old).
They have swollen looking trunks where they store water.
All grow in areas with a dry and a wet season.
Madagascar Palm Trees Ninety
five percent of Madagascar's 170 palm species are found nowhere else.
Amongst others, there are many different Beccariophoenix,
Bismarckia,
Dypsis, Halmoorea, Honkona, Hyphaene, Lemurophoenix, Marojejya,
Masoala, Raphia, Ravenea, Satranala and Voanioala species.
Other Unique Madagascar Plants
The Didiereaceae
family,
entirely unique to Madagascar, consists of plants closely related to
Cacti. Didiereaceae,
however, grow tiny leaves as opposed to Cactus. The leaves are
deciduous during the dry season. Both leaves and stems are thick, to
store as much water as possible.
Madagascar Orchids There
are about 900 species of orchids on Madagascar. This is probably the
highest number in the world per country, and about 90% of them are
endemic to the island. Thanks to their extraordinary appearance orchids
are threatened by their collectors and trade. But on Madagascar as in
many other rainfroests they are also threatened by rainforest
destruction.
Some of
the threatened species in Madagascar include Aeranthes henrici,
Angraecum longicalcar,
Angraecum magdalenae,
Bulbophyllum hamelinii,
Eulophiella roempleriana
and Grammangis
spectabilis.
Pitcher Plant
The carnivorous pitcher plant is one of the most famous Madagascar's
orchids. There are at least two species of pitcher plants found in
Madagascar. Pitcher
plants trap their
prey (insects) in the cavity of
the so-called cup. They typically grow on soils too poor in
nutrients.
