Open Access Reinstatement of Nepenthes hemsleyana (Nepenthaceae), an endemic pitcher plant from Borneo, with a discussion of associated Nepenthes taxa

Recently, N. baramensis and N. rafflesiana var. subglandulosa were described from Borneo as new taxa closely related to N. rafflesiana. However, comparison of new collections made in Borneo with N. baramensis and N. rafflesiana var. subglandulosa indicated a synonymy. Furthermore, they were identical to N. hemsleyana, an older taxon formerly treated as synonym of N. rafflesiana. Acknowledging the taxonomic differences to N. rafflesiana, the name N. hemsleyana is reinstated following the priority rule. New evidence is presented that strengthens the interpretation to split N. rafflesiana and N. hemsleyana.
