filamentis longis tenuibus glabris; duo sepalis interioribus juxta- 
posita antheris oblongis normalibus instructa, unum petalo exteriori 
juxta-positum anthera majore loculis basi elongatis divaricatis in- 
structum; duo infertilia petalis interioribus opposita, unum infertile 
sepalo exteriori juxta-positum haud raro deficiens. Pollen in 3 anthe- 
ris fertilibus consimile. Ovarium sessile, glabrum, 3-aut 2-loculare; 
loculus dorsalis 1-ovulatus interdum abortivus aut omnino deficiens, 
loculi 2 ventrales 2-aut 1-ovulati. Capsula sicca, chartacea, 3-aut 2- 
(raro abortu 1-) locularis, usque ad basim loculicide 3-2-valvis, sæpiùs 
imprimis 2-valvis, valvula dorsali cum semine incluso decidua aut 
postremo in duas partes loculicida aut cum semine connata indehis- 
cente. Loculi ventrales 2-1-0-spermi, seminibus liberis, sparsis; loculi 
dorsalis semen seminibus loculorum ventralium (nisi in Sect. Trithy- 
rocarpo) dissimile. Capsulæ valvula ventralis (nisi in C. obliqua pau- 
cisque aliis) marcescens in pedicello persistens. Semina parva, sub- 
pyramidata aut ellipsoidea plus minus complanata, loculorum 2-ovu- 
latorum Sæpissime truncata. Hilum lineare verticale. Micropyla late- 
ralis ab hilo remota (neque ei opposita), in seminibus solitariis prope 
medium sita, in seminibus truncatis propius basim truncatam appo- 
sita, Testa sicca, firma, nigra aut fusca, raro straminea, levis reticu- 
lata foveolata aut rugosa, seepe puberula aut farinosa. Embryo 
cylindricus, paullum clavatus, horizontalis.
