Notes on Discospermum sphaerocarpum Dalzell ex Hook.f., a rare species of Rubiaceae (Ixoroideae: Coffeeae) from southern India
Main Article Content
Abstract
Discospermum sphaerocarpum is a rare species in the tribe Coffeeae of the family Rubiaceae and its occurrence on the Madayippara lateritic plateau of the Kannur district of Kerala, southern India is discussed. This plant is endemic to southern India and Sri Lanka. In Kerala, this species was previously recorded from the low-altitude evergreen forests of Thiruvananthapuram district. The present study gives a detailed description, distribution and figures & images illustrating the diagnostic characters of D. sphaerocarpum for easy identification and conservation.
