Nepenthes section Tentaculatae of Borneo and Sulawesi is described and delimited, with a key to the nine species, including N. maryae of Central Sulawesi, Indonesia, which is here assessed as Vulnerable under criterion D2 using the 2001 IUCN standard. It is hypothesised that this species might trap insects using a ‘flick of the lid’ mechanism.

Three new species in the Nepenthes alata group from the Philippines, Nepenthes armin, N. tboli and N. zygon, are described and assessed as threatened using the IUCN 2012 standard. The group is expanded by the inclusion of N. truncata and N. robcantleyi, previously included in the N. regiae group. A key to the nineteen species of the group is presented.

Pitcher plants of the family Nepenthaceae are vines or subscandent shrubs which produce modified leaf organs that in most species serve to attract, trap, retain and digest animals for nutritional benefit. The sole genus within the family, Nepenthes, is abundant and diverse in Malesia. Previous taxonomic treatments of Nepenthes have relied almost entirely on the morphological features of the plants, with characteristics of the pitchers, inflorescences, leaf blades and indumentum being the most informative. Recent ecological research demonstrates that unique morphological characteristics and trap geometries provide useful taxonomic information, but this is often lost or obscured when specimens are prepared for herbaria by pressing them. In this paper, we...

Nepenthes minima is the first known pyrophytic grassland Nepenthes species from outside Indochina and the Philippines. A member of the sect. Regiae (Borneo, Wallacea, New Guinea) it is restricted to the highland grasslands of Central Sulawesi (Celebes) and has close affinities with Nepenthes maxima. The existence of Nepenthes minima, unique to these grasslands, suggests that they may be natural and predate the human influences that expanded them beginning 2000–3000 BP.

Nepenthes samar is described from the island of Samar in the Visayas of the Philippines. Similar to N. merrilliana of Mindanao, it is distinguished on foliar and floral characteristics and assessed as Critically Endangered using the IUCN 2001 standard.

Nepenthes ultra is described from low altitude, ultramafic coastal scrub in Luzon, Philippines. It is placed in the Nepenthes alata group and is assessed as Endangered using the IUCN 2001 standard. Open cast mining and touristic development are threats to this species.

Nepenthes vogelii Schuit. & de Vogel is described as a new species from Sarawak. It is compared with N. fusca Danser, from which it differs e.g. in the much smaller pitchers, of which the lid lacks appendages.

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.
