The section Ceramicalyx was established by Triana (1871) with five species namely O. stellata , O. hispidissima , O. crinita , O. gracilis and O. rostrata and its varieties viz ., var. longicollis, var. pulchella and var. ternifolia . Clarke (1879) treated all the above species except O. gracilis and O. rostrata var. ternifolia under this section. Besides these, Clarke (l.c.) also included a new variety of O. rostrata viz ., var. marginulata . Later, Cogniaux (1891) adopted the section Ceramicalyx Triana , excluding O. gracilis . The exclusion of O. gracilis by subsequent authors is justifiable as the species is fairly distinct due to its pentamerous flowers and the anthers without beak. The members of the section Ceramicalyx are perennial shrubs with tetramerous flowers, urceolate hypanthium and “S” shaped anthers with long beak. The section is represented by 3 species and 2 varieties in India.
