The genus Bauhinia is a member of the Leguminosae or pea family which is a family of considerable economic importance to humanity comprising around 700 genera and 17,000 species. A common feature of legumes is their ability to form symbiotic root nodules with Rhizobium species of bacteria which can directly fix atmospheric nitrogen. This provides the plants with an essential source of nutrition that gives them a considerable advantage in poorer soils. Within the legume family the Bauhinia are members of the sub-family Caesalpinioideae which comprises mainly tropical trees and shrubs. Other Caesalpinioids in Hong Kong include the Cassia trees and the Flame of the Forest tree Delonix regia which are very common as ornamentals for road-side planting.
