Chlorophytum sabiense (Asparagaceae): A new speices from Nigeria

Abstract

Chlorophytum Ker-Gawl. is a monocotyledonous perennial herb. Its perennating organ is rhizome which may be tuberous or not. The genus like other Liliales is characterized by having tricarpellay syncarpous ovary. In the present study, samples of the species collected from the North Central part of Nigeria and used for this study, were observed to have multiple carpels fused at the base and with free styles. This is the main diagnostic feature of the newly identified species. Multicarpellary syncarpous ovary is not only new for the genus but also for the tribe Asphodeleae of Hutchinson's system. The carpels consist of; 3 with long free styles and 3 with short free styles. Placentation is axile, with three chambers, suggesting carpellode situation in few of its carpels. The new taxon is therefore named Chlorophytum sabiense. Omokanye, sp. nov. TYPE: Nigeria, Sabi
