 than superior radicle. — A hirsute tree ; leaves opposite pinnate, 

 sometimes 1-foliolate; leaflets opposite; flowers in large terminal 

 much branching cymiferous racemes ; bracts and bractlets concave, 

 opposite or alternate {Tropical Eastern Australia). See p. 377. 



78. Acrophyllum Benth. — Flowers hermaphrodite, 4-6-merous; 

 receptacle small convex. Calyx gamophyllous at base ; lobes oblong- 

 acute, valvate, persistent. Petals as many elongated, imbricate.

 long-exserted, inflexed in the bud ; anthers small, 2-dymous. Germen 

 superior, sub-2-locular ; styles 2, straight elongated subulate, per- 

 sistent, stigmatose at simple apex ; ovules go , 2-seriate in each cell 

 (more or less complete). Capsule coriaceous subturgid, septicidally 

 2-partible ; valves terminated by style, go -seeded at edge. Seeds 

 papillose outside ; albumen...? — An erect branching shrub; leaves 

 opposite or verticilhite, sessile oblong, coarsely dentate, veined; stipules 

 rigid, tardily deciduous ; flowers numerous, spuriously verticillate in 

 sessile axillary cymes ; pedicels bracteolate at base, defract when 

 fruiting (Southern Australia). See p. 377. 



79? Ackama A. Cunn.— Flowers minute; receptacle shortly 

 cupulate. Sepals 5, 3-angular valvate persistent. Petals 5, linear- 

 spathulate thin deciduous, inserted with stamens outside a slightly 

 perigynous disk, divided into 5 oppositipetalous 2-lobed scales.
