corollam primum involvente et a posticis operto. Corolla gamopetala; 
tubo brevi v. elongato, latiusculo v. tenui; limbi lobis subæqualibus 
tenuissime membranaceis, subvalvatis v. leviter imbricatis, nunc 
leviter corrugatis. Stamina 6, fauci inserta, quorum oppositipetala 3, 
fertilia, perianthio breviora; filamentis erectis brevibus, gracilibus 
v. subulatis; antheris longioribus ad basin dorsifixis, oblongis erectis; 
loculis contiguis linearibus, nune basi liberis, extrorsum rimosis, 
rarius ob connectivum transverse elongatum valde distantibus. Sla- 
minodia alternipetala 3, 2, v. 0; filamento brevi; anthera sterili plus 
minus dilatata, 2-loba, v. lobis linearibus penicillatis. Germen sessile 
liberum ; stylo terminali simplici v.sæpius plus minus longe 3-ramos0; 
ramis apice stigmatoso varie dilatatis. Ovula in loculis plus minus 
completis œ, orthotropa obliqua; micropyle supera. Fructus capsu- 
laris loculicidus. Semina ovoidea v. oblongo-fusiformia, extus lon- 
gitudinaliter costata; hilo basilari; apice tuberculata; albumine 
farinaceo; embryone apicali late turbinato v. lenticulari. — Herbæ
