Nepenthes hemsleyana Macfarl. (1908) 61. — Type: Burbidge s.n. (lecto, designated here, K Acc. No. K000651485 ; iso K Acc. Nos. K000651484 and K000651486 ), Borneo , Sarawak, Lawas River, 1877.

Nepenthes rafflesiana Jack var. subglandulosa J.H.Adam & Hafiza ( Adam & Hamid 2006) 348. — Type: JHA8333 (holo UKMB, n.v.; iso UKMB, n.v.), Sarawak State of Malaysia, Miri, Lambir Hill, along the road to Telekom Malaysia Receiving Station, growing in open vegetation with N. gracilis and dominated by thicket of fern Dicranopteris linearis .

Nepenthes baramensis C.Clarke,J.A.Moran & Chi.C.Lee (2011) 230. — Type: Hotta M. 12419 ( SAR, n.v.), Brunei, Belait District, Seria,en route K . Badas to Seria along the railway of B. S. C., 7 Dec. 1963 .

Etymology. The specific epithet honours Kew botanist William Botting Hemsley (1843–1924), who described N. macfarlanei Hemsl. in 1905.

Distribution — Borneo: Baram district and Bintulu area of Sarawak, and Belait and Tutong districts of Brunei (Clarke et al. 2011, pers. observ.). Probably more widespread on Borneo, but see discussion below.

Hybrids — In Brunei, N. ampullaria Jack × hemsleyana (M. Scharmann 1105) and N. hemsleyana × rafflesiana have been documented, but occur only in habitats resulting from anthropogenic disturbance. The former is distinct from sympatric N. × hookeriana Lindl. (M. Scharmann 1106) in the presence of a waxy zone, hairs on the upper side of the lid (see Table 2) and the narrower peristome.

Note — A very accurate description of N. hemsleyana is already available in the description of its heterotypic synonym N. baramensis (Clarke et al. 2011) . See the same publication for further specimens, informal synonyms, further notes and a table to distinguish it from N. rafflesiana . The present study led to the identification of several additional characteristics ( Table 2).
