gynseceum glandular at margin in 3-lobes, opposite exterior sepals, 

 emarginate 2-lobed, incised; anthers ellipsoidal extrorse 2-rimose. 

 Germen surrounded by thin annular, hypogynous disk ; cells 3, 2- 

 OTulate ; obturator thick ; seeds exarillate albuminous. — Shrubs or 

 undershrubs divaricate-ramified or very ramified; leaves simple 

 entire narrow (subericoid) penninerved, sometimes sessile, 3-foliolate ; 

 stipules narrow or not conspicuous ; flowers ^ in dense cushion axil- 

 lary cymose ; female often solitary.^ - [Australia, Tasmania?) 



123. Micrantheum Desf.* — Flowers dioecious (nearly of 

 Caletia) ; stamens 3, opposite exterior sepals. Eudiment of gynse- 

 ceum glandular 3-lobed, opposite interior larger sepals. Other 

 characters of Caletia. — An ericoid virgate-ramified shrub ; leaves 

 alternate narrow rigid stipulate ; inflorescence of Caletia. {Australia.^) 



124 ? Choriceras H. Bn.^— Flowers dioecious (nearly of Caletia) 

 or monoecious (?) folioles of imbricated calyx 6, 2 -seriate ; exterior in 

 male flower short. Stamens 6, (or 5, 7); filaments free inserted round 

 base, of slightly thickened rudiment of gynseceum conical-cylin- 

 drical entire recurved at apex ; anthers extrorse ; cells adnate, 

 rimose. Staminodes (or bacillar glands ?) 3 in the female flowers 

 placed before interior sepals, hypogynous erect, incrassate at base. 

 Germen sessile ; cells 3 alternating with staminodes free above from 

 middle and each revolute in free style attenuate at apex stigmatife- 

 rous within ; ovules in each 2-nate, inserted at middle of internal 

 angle ; micropyle extrorse superior ; obturator rather fleshy fornicate. 

 Fruit 3-ooccous, crowned with 3 discrete peripherical horns ; 

 columella short thin; cells finally 2-valved; seeds in each 1, 2, 

 exarillate. — A shrub, branches opposite the younger one villulose. 

 leaves opposite, shortly petiolate, exstipulate penninerved ; flowers in
