 auriculate and coalescing to form a short sheath round radicle. — 

 Unarmed trees ; leaves 2 -pinnate ; leaflets cc -jugate ; flowers in 

 racemes or spikes, axillary or panicled at extremities of branches 

 {Asia, Africa, tropical Australia). — See p. 21. 



2. Elephantorrhiza Benth. — Flowers hermaphrodite, more 

 rarely polygamous (of Adenanthera). Legume almost straight, 

 piano-compressed thick coriaceous ; sutures persistent continuous ; 

 valves becoming free ; endocarp coming away entire from exocarp. 

 Seeds transverse orbiculate compressed. — Low underslmibs ; rhi-
