Dear sir, When you collect C. diffusa from Thiruvannamali? It is rediscovered in this February after 160 years by V. S. ramachandran et al. Yes may be that is a variant of umbellata In my hand also have one. For validation I want the live collection. If that is interesting then we can do a compined work.
Actually I am specialized in Zingiberaceae in India under Dr. M. Sabu, Professor, Dept. of Botany, Calicut University. The revision is over. My other specilaized genera: Premna, Striga and Caralluma Keep in touch Thanking you -- *Prabhu Kumar K M* Scientist Plant Systematics & Genetic Resources Division Centre for Medicinal Plant Research (CMPR) & 'CMPR' Herbarium Kottakkal Arya Vaidya Sala Kottakkal, Malappuram *E-mail: prabhumkris...@gmail.com*
