Dichrostachys] xliv. LEGUMiNOSiE. 309 



The flowers are produced in pendulous spikes about \h in. long, the 

 lower half of which is bright yellow, the other half rose-coloured ; the 

 foliage is of a glaucous green, and the leaves are bi-pinnate, 14 and 

 more jugate ; the leaflets from 26 to 30 pairs ; the legume is nearly 

 an inch broad, and peculiarly twisted (W. Bull, I.e.). The species 

 frequently constitutes extensive forests of small height but of singular 

 elegance, mixed with various species of Acacia and Alhizzia ; some- 

 times it gives a variety of colour to the forests composed of Ster- 

 culiaceas, Ficus, and Celtideae, with its brighter and more glossy 

 foliage, and at other times it constitutes the principal part and gives a 

 characteristic feature to the woods. (Welwitsch, I.e.)

 stachys : — ■
