subequal imbricated. Petals 5 ; highest petal largest unguiculate, 

 very complex cucullate in aestivation, usually outermost ; 4 anterior 

 smaller, or very small scale-like, or more rarely 0. Grermen stipitate, 

 more or less excentric, 2- cc -ovulate ; style slender ; apex truncate 

 or capitate stigmatiferous. Legume obliquely-orbiculate ovate 

 oblong or falcate, piano-compressed 2-valved ; placental suture some- 

 times thickened or dilated. Seeds 1 or few, orbiculate compressed ; 

 embryo exalbuminous ; cotyledons thick ; radicle straight included. 

 —Unarmed trees ; leaves pari- or more rarely imparipinnate ; 

 leaflets 1, or pauci-, more rarely multijugate; stipules leaf-like or 

 small caducous, more rarely ; flowers in simple or branched, ter- 

 minal or axillary racemes ; bracts caducous ; bractlets 2, rather thick 

 or coriaceous, inclosing bud as 2 valves, finally spreading (Tropical 

 America and Africa). See p. 101. 



37. Berlinia Soland. — Flowers large (of Vouapa) ; sepals 5, thin 

 imbricated ; highest petal largest ; 4 anterior, a little smaller or 

 oftener rudimentary or 0. Stamens 10, or more rarely 5 alterni- 

 petalous, fertile ; filaments free or connate close to base ; anthers 

 uniform introrse. Grermen very excentric, stipitate, inserted high 

 below androceum, co-ovulate, style slender ; apex truncate or capitate, 

 stigmatiferous. Fruit . . . ? — Unarmed trees ; leaves paripinnate ; 

 leaflets coriaceous ; stipules small caducous, or more rarely broad 

 leaf-like ; flowers in simple, or oftener compound, much-branched 

 terminal racemes ; bracts coriaceous caducous ; bractlets broadly 

 concave thick spathulate, inclosing bud as valves, finally spreading 

 or deciduous (Western Tropical Africa). See p. 104. 



38. Daniella Benn. — Flowers subregular ; receptacle narrowly 

 turbinate, lined by a disk. Sepals 4, slightly unequal, coloured 

 imbricated. Petals 5 ; highest small or rather large ; 4 anterior 

 usually rudimentary or ; 2 lateral rarely rather large, imbricated. 

 Stamens 10, free (of Berlinia). Germen excentric stipitate cc-ovulate; 

 style terminal; apex capitate stigmatiferous. Legume stipitate 

 obliquely ovate-oblong, sub falcate piano-compressed coriaceous 

 2-valved; endocarp separating elastically. Seed usually 1, com- 

 pressed ; embryo exalbuminous ; radicle short straight. — Unarmed 

 trees ; leaves paripinnate ; leaflets coriaceous ; stipules lateral 

 caducous ; flowers in compound much-branched racemes at extre-
