298 NATURAL HISTORY OF PLANTS. 



Seeds reniform or suborbicular, much compressed, exarillate. — 

 Herbs, undershrubs, or more rarely shrubs, glabrous or shaggy; 

 leaves pari- or imparipinnate ; leaflets small, usually falcate exstipel- 

 late : stipules persistent, membranous or scarious : flowers 1 in short, 

 often 1 -lateral, racemes; bracts and bractlets scarious or striated, 

 persistent ; bractlets appressed to flowers (Tropical Asia, South-eastern 

 Africa*). 



133. Discolobium Benth. 3 — Calyx gamosepalous ; lobes 5, nearly 

 equal or 2 superior connate. Petals shortly unguiculate ; standard 

 suborbicular ; wings obovate, about equal to standard ; keel shorter 

 than wiugs, nearly straight, obtuse. Stamens 10, 1-adelphous, finally 

 evenly 2-adelphous ; the sheath becoming longitudinally cleft on both 

 sides ; " vexillary and lowest stamens almost free from base ;" anthers 

 uniform. Germen shortly stipitate pauciovulate ; style curved 

 glabrous ; stigma minute oblique terminal. Legume short, at 

 superior suture nearly straight, at inferior expanded into 3 horizontal 

 segments or disks ; middle segment largest reniform reticulated 

 fertile 1-seeded indehiscent ; lowest and highest sterile, much 

 smaller. Seed lunulate-reniibrm exarillate. — Undershrubs ; leaves 

 imparipinnate; leaflets go or more rarely 1, 8, exstipellate ; stipules 

 small ; flowers 4 in axillary racemes ; peduncle elongated rigid ; 

 pedicels solitary ; bracts and bractlets small persistent (Brazil*). 



134. Ormocarpum Pal. Beau v. 6 — Calyx gamosepalous ; lobes 5, 

 unequal ; 2 superior broader, close or connate to a variable extent ; 

 lowest often longer than others. Standard suborbicular unguicu- 

 late ; wings obliquely obovate ; keel about equal to wings, broad 

 curved, obtuse or rather acute at apex. Stamens 10, connate into a 

 sheath often finally longitudinally cleft above and below ; anthers 

 uniform. Germen sessile ; ovules cc ; style slender, much inllexed ; 

 apex not thickened or minutely capitate, stigmatiferous. Legume
