dular or foveolate disk ; filaments free, dilated at base (the oppositi- 
petalous rather shorter); anthers introrse, 2-rimose. Carpels 4, 5, 
oppositipetalous ; germens free or adnate at base between them- 
selves and with the summit of receptacle, l-locular; styles same in 
number, free at base, shortly coalescing in column capitellate stigma- 
tiferous at apex; ovules in each germen 2-, 2-seriate descending 
or subtransverse anatropous. Fruit carpels 4, 5, nearly free or 
more or less connate at base, dry capsular, or inwardly dehiscing at
