Biology And Ecology

  • The original specimens were collected from moist forests of Coimbatore. (Basu, S.K. 1992: Rattans (canes) in India. A Monographic Revision)A


  • The cane is strong and can be suitably utilised for making furniture. Intensive survey of this species is needed for assessing its cultivation prospects. (Basu, S.K. 1992: Rattans (canes) in India. A Monographic Revision)A
