Flowers dioBcio-polygamous. Calyx of five nearly equal 

 and herbaceous oblong-lanceolate sepals, somewhat irregu- 

 larly united at the base only, quincuncially imbricated in 

 a3stivation (rarely of only four sepals?), deciduous. Petals 

 4, the anterior one absent, or often 5, alternate with the se- 

 pals and quincuncially imbricated in aestivation (rarely six), 

 hypogynous on the edge of a thickened and truncate torus, 

 or obscurely perigynous from its union with the very base 

 of the calyx, deciduous, unequal when there are five, when 

 four nearly equal, unguiculate ; the claws at length as long 

 as the sepals, nearly erect, thickened, woolly, especially on 

 the inner side, conspicuously appendaged at the summit with 

 a fimbriate crest composed of short and fleshy tufted threads ; 

 the lamina obovale, spreading, often irregularly erose-crenu- 

 late. Disk an oblique fleshy lamina projecting on the poste- 

 rior side of the flower and connate with the base of the stipe 

 of the ovary, which it embraces. Stamens 7 to 10, usually 8 

 or 9, inserted on the oblique edge of the disk, more or less 

 declined ; in the sterile flowers much exserted and unequal, 

 the anterior shorter ; in the fertile flowers all usually shorter
