racemes or more usually spikes ; inflorescences simple or much

70. Burkea Hook. — Eeceptacle shortly concave, lined by a disk. 

 Calyx campanulate, evenly 5-lobed. Corolla subregular, imbricated. 

 Stamens 10; filaments short; anthers uniform, introrse 2-rimose ; 

 connective inflexed glandular appendiculate at apex. Germen 

 central, sessile or very shortly stipitate, 2-ovulate ; style very short, 

 thick ; stigma terminal concave. Legume oblong piano-compressed 

 subcoriaceous indehiscent (?). Seeds compressed, " funicle filiform ; 

 outer coat thin ; inner cartilaginous-fleshy ; albumen ; cotyledons 

 flat thin ; radicle straight short included." — Trees or shrubs, un- 

 armed ; leaves 2-pinnate ; pinnae paucijugate ; leaflets coriaceous ; 

 stipules minute; flowers small (polgyamous ?) in interrupted elongated 

 simple or branched spikes ; bracts minute {Tropical and southern 

 Africa). See p. 141. 



71. Erythrophlceum Arz. — Eeceptacle shortly cupuliform, lined 

 by a disk. Calyx campanulate regular, shortly 5-toothed. Petals 

 5, equal, subvalvate or slightly imbricated. Stamens 10, perigynous, 

 free, equal or alternipetalous shorter ; anthers uniform 2-rimose. 

 Germen stipitate central oo-ovulate ; style short ; stigma terminal 

 obtuse. Legume oblong compressed, thickly coriaceous, pulpy 

 within between seeds, 2-valved. Seeds compressed, embryo albu- 

 minous ; cotyledons subfoliaceous ; radicle straight, shortly exserted. 

 — Unarmed trees ; leaves 2-pinnate ; leaflets coriaceous, often alter- 

 nate ; flowers small, in dense much-branched racemes at extremities 

 of branches; bracts small; bractlets {Tropical Africa and Australia). 

 See p. 142. 



72? Brandzeia H. Bn. — Flowers regular; receptacle obconical, 

 lined by a disk. Sepals 4, 5, perigynous imbricated. Petals 5, nearly 

 equal, furnished with long claws, imbricated. Stamens 10, perigy- 

 nous : filaments free slender, inflexed in bud, finally long exserted ; 

 anthers introrse 2-riraose versatile ; connective glandular. Germen 

 central stipitate cc-ovulate; style slender involute; apex scarcely 

 dilated, stigmatiferous. Legume stipitate elongated piano-com- 

 pressed, unevenly bent ; gibbous on both sides, coriaceous woody,
