Kew Bulletin Aims and scope Submit manuscript

Summary

Ceropegia graminea K.Suwann. & Kidyoo was recently discovered from eastern Thailand. It is here described and illustrated. Photographs and a comparison of the diagnostic features of the new taxon with those of the morphologically similar species, C. suddeei Kidyoo and C. thailandica Meve, are provided. These three species are characterised by a 1-flowered cyme and a corolla tube tipped with twisted, linear corolla lobes that are covered with glandular hairs. However, C. graminea is clearly distinguished from its close relatives in having a decumbent, glabrous stem and branches with needle-like leaves.
