dicecious apetalous. Sepals 4, in male flower, in short cupule at 
base; in female, in urceolate-globose tube, much imbricated.  Sta- 
mens 4 (of which 2 anterior), alternating with the calyx lobes 
and marginally inserted at the base of the disk; filaments short ; 
anthers introrse, apex exappendiculate, base subcordate, longi- 
tudinally 2-rimose. Germen free (in male flower rudimentary), 1- 
locular ; style short, afterwards dilated in stigmatiferous head, 3—4- 
lobed ; placentas parietal, 3, 4; “ovules on each crowded. Berry 
coriaceous, 1-locular, indehiscent or finally 3, 4-valved; seeds » ; 
testa hard; embryo axile albuminous; radicle straight inferior.’”— 
A sbrub or tree; leaves alternate, large, remotely serrate ; stipules 
lateral, 2; flowers small, in ramified spikes springing from trunk or 
branches ; each surrounded at base by a bract and 2 bractlets, lateral 
membranous, concave, connivent in false involucel (Zrop. South 
America). 
16. Ryania Vani.*—F lowers hermaphrodite apetalous ; receptacle 
subplane or slightly cupulate. Sepals 5, sometimes slightly peri- 
gynous, much imbricated.* Stamens o, slightly perigynous free ; 
anthers linear ; cells longitudinally dehiscent at margin or introrsely. 
Disk interior to stamens, sometimes short cupulate, sometimes much 
more evoluted or subpetaloid unequally cleft. Germen subfree, 1- 
locular ; style erect, apex dilated stigmatiferous, subequally lobed or 
divided into 2-6 branches, capitate stigmatiferous reflexed ; placentas 
parietal 2-5, oppositisepalous, o-ovulate. Fruit dry, ligneous- 
suberose, 2—5-valved. Seeds &, arillate; testa crustaceous ; embryo 
more or less albuminous, cotyledons wide ; radicle straight.—Trees ; 
hairs often stellate; leaves alternate entire penniverved, transversely 
small veined, sometimes pellucid-punctuate ; flowers‘ axillary solitary 
or few cymose (Zropical America’).
