Piper ribesioides is a lesser known woody species known to occur in Myanmar, Andaman-Nicobar Islands, and Malesia. This taxon is located from the Andaman Islands in 1834 by Dr Helfer. He was a geologist who made extensive botanical collections from Tenasserim (Myanmar) and Andaman Islands. Unfortunately, he was murdered by the aborigines of northern Andaman Islands and his all collections from Tenasserim and Andaman Islands got mixed up causing much confusion about the geographical origin of the botanical collections. Hence the locality of all herbarium collections made by Helfer have been designated as Tenasserim/Andaman Islands. Exact occurrence of several collections made by Helfer was later reconfirmed by other botanists during their explorations. One of his collections deposited at Central National Herbarium, Howrah (CAL) designated the locality as Tenasserim/Andaman Islands was Piper ribesioides; however, the occurrence of this species in Andaman Islands was doubted until its rediscovery in 1990 by Mathew and Abraham. This woody climbing liana is evidently rare in the Andaman Islands. Living accessions of this rare insular species from the Andaman Islands is conserved at the Field Gene Bank of Jawharlal Nehru Tropical Botanic Garden and Research Institute, Trivandrum, South India.
