A spectacular new species ofNepenthesL. (Nepenthaceae) pitcher plant from central Palawan, Philippines

Abstract

A new species of Nepenthes L., N. attenboroughii (Nepenthaceae), from Palawan Island in the Philippines, is described and illustrated. It is restricted to rocky, ultramafic soils that comprise the summit region of Mount Victoria, Municipality of Narra, where it occurs in isolation from other members of the genus. On the basis of the morphological features, this new taxon appears to be related to both N. mira Jebb & Cheek of Palawan and N. rajah Hook.f. of Borneo. Its substantial size places it among the largest of known pitcher plants. The diagnostic morphological characters are discussed and an updated key is provided for a revised complex of Nepenthes species from the Palawan and North Borneo phytogeographical region. © 2009 The Linnean Society of London, Botanical Journal of the Linnean Society, 2009, 159, 195–202.

“…However, horticulturists and enthusiasts often view the taxonomic importance of certain morphological traits differently from taxonomists and this may give rise to multiple, competing interpretations for some taxa. New discoveries are still being published on a regular basis , McPherson 2009, Robinson et al 2009), making it difficult to address the issue at present.…”

Drosera ultramafica (Droseraceae), a new sundew species of the ultramafic flora of the Malesian highlands

“…Diels 1906, Van Steenis 1953, Beaman et al 2001, Anfraix 2005, as well as from Leuser National Park of northern Sumatra (De Wilde & Duyfjes 2001). A recent expedition to the Philippines (see Robinson et al 2009, McPherson 2009) has revealed the presence of this new taxon from ultramafic habitats on two different mountains located on the island of Palawan. It is described here from herbarium specimens and observations made during that expedition.…”

“…The low soil nutrient content of ultramafics leads to a rather open vegetation (Nagy & Proctor 1997), providing conditions ideally suited to carnivorous plants, which are adapted to survive on poor soils through the capture of invertebrate prey for additional nutrition. Indeed, a high α-diversity of Nepenthes L. (Nepenthaceae) is confined to ultramafic soils in Malesia (Robinson et al 2009). …”
