Calyx colored, five-cleft, with a hemispherical or turbinate 

 tube ; the lobes triangular, membranaceous and petaloid, val- 

 vate in aestivation (the bud five-lobed), usually remaining 

 inflexed or connivent, deciduous by a circumscissile line, 

 leaving the persistent tube at the base of the fruit. Disk 

 fleshy or spongy, thickened upwards, adnate to the calyx- 

 tube and closely surrounding the ovary, with which it is 

 usually more or less coherent. Petals 5, inserted on the 

 thickened margin of the disk alternate with the lobes of the 

 calyx, much longer than they, exserted, deflexed or widely 

 spreading in flower, conspicuously unguiculate, the limb 

 cucullate, infolded around the stamens in asstivation, decidu- 

 ous. Stamens 5, inserted with the petals and opposite them, 

 as long as the petals or longer, often persistent : filaments 

 filiform : anthers didymous or four-lobed, introrse, two- 

 celled, the cells opening longitudinally. Ovary three-celled, 

 immersed in the disk, and often adnate to it, sometimes three- 

 angled, the angles often surmounted by a fleshy protuber- 

 ance or a gland : styles 3, commonly united below into 

 one : stigmas introrse or terminal. Ovule solitary in each 

 cell, erect from its base, anatropous, the raphe next the axis.
