Abstract: An expedition to the highest peak of the Kemul Massif located a number of different Nepenthes taxa, including the type populations of N. fusca Danser and N. mollis Danser (Nepenthaceae), neither of which have been observed in situ since they were first collected from Kemul in 1925. Studies of the type form of N. fusca show that N. fusca s.lat. includes two other species, one largely restricted to Sabah’s Crocker range, here reinstated as N. zakriana (J.H.Adam & Wilcock) J.H.Adam & Hafiza, and a more southerly distributed species from Brunei, Sarawak and Kalimantan, named here as N. dactylifera A.S.Rob, Golos & Barer. Analysis of the type population of N. mollis indicates that N. hurrelliana Cheek & A.L.Lamb is a heterotypic synonym of N. mollis, and reveals an additional undescribed Nepenthes species from Sarawak and Kalimantan with a widespread but highly localised range.

Abstract: Nepenthes fractiflexa is described as a new species from Sarawak and Kalimantan. The species is characterised by a number of unusual growth habits: plants readily produce aerial offshoots from their leaf axils, giving rise to a highly branched architecture of a complexity rarely seen in the genus even those axillary buds not destined to develop further are activated and often elaborated into bract-like prophylls up to 5 cm long and the inflorescence emerges close to the middle of the internode rather than from the leaf axil, as is typical of all other known species, leading us to make the first proposal for concaulescence in Nepenthes. These traits—coupled with the plant’s distinctive, long-decurrent petiolar wings and fractiflex climbing stems—distinguish it from its putative closest relative, N. mollis. The known distributions of N. fractiflexa and N. mollis are reviewed in light of recent discoveries. The apparent geographical disjunction between the two species is discussed in the context of edaphic and other ecological factors. Owing to its large range and remote, predominantly ridgetop habitat—but small number of recorded localities and in iduals—the conservation status of N. fractiflexa is assessed as Near Threatened under the IUCN 3.1 criteria.

Abstract: Nepenthes diabolica, a new species of tropical pitcher plant from Central Sulawesi, is described and illustrated. It is a high-montane, terrestrial to epiphytic taxon, distinguished by its elaborately flanged peristome and rufous, woolly pitcher indumentum. N. diabolica is a member of section Tentaculatae, showing morphological affinities with N. hamata. Nevertheless, the two species can be distinguished by morphological characters as well as by ecology and geography. A diagnostic key to the species of section Tentaculatae is provided. Owing to its highly restricted range, small number of recorded in iduals, and desirability among plant collectors, the conservation status of N. diabolica is assessed as Critically Endangered under the IUCN criteria. Finally, N. hamata, until now based on lost types and mixed paratypes, is lectotypified using recently uncovered original material.
