Q: Nepenthes: species of Peninsular Malaysia

A: Malaysia consists of two main land-masses. East Malaysia consists of its presence on Borno, which I already talked about a few FAQ pages ago. West Malaysia, here referred to as Peninsular Malaysia, is separated from Borneo by the South China Sea, and is bound to the north by Thailand and is terminated to the south by Singapore.

(By the way, Singapore's set of pitcher plants consist of a subset of Peninsular Malaysia's, i.e. Nepenthes ampullaria, N. gracilis, and N. rafflesiana.)

Most of the species in Peninsular Malaysia occur elsewhere; only five species (essentially the highland species) are endemic.

Nepenthes benstonei--Unique in regularly producing multiple inflorescences simultaneously, and also in its very thick, glossy cuticle. Known only from the type locality in Kelantan, although additional collections suggest it may occur elsewhere.

Nepenthes gracillima--This species is closely related to N. ramispina, and there is much lively debate (read spitting contests) about whether they should be considered separate species. In general terms, N. gracillima is a smaller version of N. ramispina with commensurately small or less developed features. But really, refer to Clarke (2001) for a complete discussion. Nepenthes gracillima is restricted to the Tahan Range and other nearby mountains.

• N. sanguinea
• N. ramispina
• N. albomarginata

Nepenthes macfarlanei--A plant that has pitchers with hairs on the underside of the lid. Why these hairs occur is unknown. Do they increase surface area to encourage the release of some compound? Are they some other kind of attractant? This plant is scattered throughout many sites in Peninsular Malaysia.

Nepenthes ramispina--A plant with really black pitchers that are, in my eyes, spectacular. Found from a number of sites in the center of Peninsular Malaysia.

Nepenthess sanguinea--Although this species doesn't have a madly enlarged peristrome, it has a very graceful, gently beautiful pitcher shape. A fairly forgiving plant that is good for the experienced novice. Distributed throughout Peninsular Malaysia.
