Nepenthes ramispina

Nepenthes ramispina ( /nɨˈpɛnθiːz ˌræmɨˈspaɪnə/; from Latin: ramus = branch, spina = spine, spur) is a highland Nepenthes pitcher plant species, native to Peninsular Malaysia. It is very similar to N. gracillma and there is much debate about whether the two should be treated as separate species.
