The wood anatomical variation in Nepenthes displays variation for some characters dependent on soil type, precipitation and stem length, but is largely conservative. The helical-banded fibre-sclereids that mainly occur idioblastically in pith and cortex are synapomorphic for Nepenthes , while other typical Nepenthes characters evolved convergently in different Caryophyllales lineages.

SummarySix new species: Bulbophyllum caniceps, B. cochinealloides, B. fierenanaense, B. geminiflorum, B. oenanthum and B. rudolphus are described for the first time. The identity and nomenclature of Bulbophyllum cylindrocarpum is discussed and its var. andringitrense is recognised at species rank as B. jeanbosseri. Bulbophyllum aubrevillei and B. kieneri are compared with the latter becoming a synonym. The history and identities of Bulbophyllum pentastichum vs B. quadrifarium are clarified and the necessary taxonomic changes and type selections are made. A new sect. Inversiflora is formally described.
