being horizontal. Nepenthes inermis × N. talangensis has been the subject of taxonomic confusion in the past. In a 1973 article on the Nepenthes of Borneo, Singapore, and Sumatra, Shigeo Kurata incorrectly identified specimens of this hybrid as belonging to N. dubia. In 1997, Matthew Jebb and Martin Cheek published their monograph "A skeletal revision of Nepenthes (Nepenthaceae)", in which they referred to N. dubia plant material from Mount Talang (Kurata s.n. SING). Charles Clarke later identified Kurata s.n. as representing N. inermis × N. talangensis. In 2001, Kurata described this hybrid as a new species, N. pyriformis. Clarke rejected this interpretation in his monograph, Nepenthes of Sumatra and Peninsular Malaysia, published the same year. Clarke found that the type specimen of N. pyriformis, Kurata & Mikil 4230 NDC, matches the appearance of N. inermis × N. talangensis "in most respects". References Further reading Hernawati & P.
