58. Trewia L.^ — Flo-wers dioecious apetalous ; receptacle shortly 

 conical. Male sepals 3, 4, free or connate at base, valvate. 

 Stamens oo ; filaments free or connate at base ; anthers erect, 

 2-locular ; exterior usually extrorse ; others introrse or laterally rimose. 

 Female calyx 3-4-merous, valvate or slightly imbricate at apex, gamo- 

 phyllous at base afterwards unequally -broken, sometimes reflexed at 

 anthesis. Germen sessile ; cells 3, 4, 1 -ovulate ; micropyle extrorse 

 superior obtected by obturator ; style erect, afterwards divided iato 3, 

 4, elongate, inwardly stigmatiferous, much papillose branches. ' Fruit 

 indehiscent suberose; endocarp hard subosseous; seeds exarillate 

 glabrous copiously albuminous. — A tree ; leaves opposite or subalter- 

 nate petiolate, 2 -stipulate, penninerved, digitinerved at base ; stipules 

 linear-subulate, very caducous ; flowers racemose or spicate.^ (Southern 

 Asia cont. and ins?^ 



59 ? Laslocroton Geisbb.'' — Flowers dioecious apetalous ; calyx 

 6-partite, valvate. Stamens oo, central, inserted on rather convex 

 receptacle ; filaments free ; anthers erect, 2-locular, longitudinally 

 rimose. Germen 3-locular, surrounded at base with thick hypogynous 

 disk; cells 1 -ovulate; style branches 3, short thick, inwardly 

 sulcata, inflexed lobulate at margin. Capsules depressed-globose, 

 3-dymous ; seeds smooth exarillate. — A tree ; leaves alternate petio- 

 late penninerved, digitinerved at base, reticulate-veined tomentose ; 

 hairs simple ferruginous ; male flowers in short densely glomerate 

 spikes ; female in elongated racemes naked below. {Jamaica?) 



60. Pycnocoma Benth.^ — Flowers monoecious (nearly of 

 Echinus) ; male calyx 3-6 -partite, valvate. Stamens go ; filaments
