Calyx deeply five-cleft, with a very short hemispherical 

 tube ; the lobes somewhat petaloid, erect or spreading, val- 

 vate in asstivation ; the base persistent. Disk thick and 

 fleshy, lining the tube of the calyx, and surrounding the 

 ovary but free from it. Petals 5, obovate or lanceolate, 

 sessile, entire, usually acute, about the length of the lobes 

 of the calyx and inserted alternate with them into the edge 

 of the disk, involute around the stamens in a3stivation, con- 

 cave or cucullate-infolded, deciduous. Stamens 5, opposite 

 the petals and inserted with them, usually shorter than they : 

 filaments subulate : anthers ovate or cordate, two-celled, 

 introrse, fixed below the middle, the cells opening longitu- 

 dinally. Ovary half immersed in the disk, free, ovoid, two- 

 celled: styles united into one: stigmas 2. Ovule solitary 

 in each cell, erect from its base, anatro})ous, the raphe next 

 the axis.
