Yellow Tree Bauhinia (BauhiniaTomentosa)

Family Caesalpinioideae
This medium to large shrub with its attractive light green two-lobed leaves produces beautiful bright yellow flowers with black to maroon coloured centres from December to March.


Description
Medium to large shrub to a small tree, up to 4m in height. Leaves are divided into two lobes, light green in colour, with a leathery texture, carried on branches that are often drooping. It produces large bell-shaped, bright yellow flowers with a black to deep maroon coloured centre from December to March. The fruit are pea like, slender and velvety. They are light green, turning a pale brown with age and are produced from January to June or even later. Bark is grey or brown.
 Derivation of name and historical aspects.

The genus name " Bauhinia " honours herbalist brothers from the 16 th century, Johann and Caspar Bauhin. They were identical twin brothers, making it a very apt name as the two lobes of the leaves, when folded together, are identical.
 Previously a large genus, it has now been divided into a number of genera according to the flower shapes. Several South African bauhinias are in cultivation including the well-know Pride of De Kaap - Bauhinia galpinii and Bauhinia bowkeri.



The specie name "tomentosa" means hairy and it refers to the velvety/ hairy pods.
 Ecology

The flowers from this tree, rich in pollen and nectar, attract various insects such as butterflies and bees. In turn these insects will attract insect eating birds. Certain birds and the larvae of certain moth species feed on the flowers. This is also a host plant for many butterfly species, with the larvae feeding on the leaves.


Uses and cultural aspects

Not much is known about the specific medicinal or cultural uses of this specie of Bauhinia, although it is said to be used widely medicinally.



Three other species of Bauhinia are also used medicinally for everything from coughs, convulsions and constipation to pneumonia and venereal diseases. ( Bauhinia galpinii, Bauhinia thonningii, Bauhinia petersiana)
