Abstract

Two new species of Nepenthes from Terengganu, Peninsular Malaysia, N. latiffiana M. N. Faizal, A. Amin & N. Dome and N. domei M. N. Faizal, A. Amin & A. Latiff, are described and illustrated.

Highlights

In Peninsular Malaysia, a total of eleven species of pitcher plants (Nepenthes) or locally known as “periuk kera” have been recorded (Jebb and Cheek 1997; Cheek and Jebb 2001; Clarke 2001; McPherson 2009)
The first taxonomic account of the genus in Peninsular Malaysia was given by Ridley (1924) who recorded a total of ten species, namely N. ampullaria Jack., N. albomarginata Lobb., N. gracillima Ridl., N. alba Ridl., N. ramispina Ridl., N. sanguinea Lindl., N. macfarlanei Hemsl., N. gracilis Korth., N. rafflesiana Jack and N. phyllamphora Willd. (= N. mirabilis (Lour.) Druce)
Clarke (1999) added N. benstonei, a species known from Bukit Bakar, Kelantan, to the list and the latest was Adam and Hamid (2007) who described N. sharifah-hafsahii which happens to be a natural hybrid between N. gracilis and N. mirabilis rather than a true species (McPherson 2009)

Summary

Introduction

In Peninsular Malaysia, a total of eleven species of pitcher plants (Nepenthes) or locally known as “periuk kera” have been recorded (Jebb and Cheek 1997; Cheek and Jebb 2001; Clarke 2001; McPherson 2009). After Ridley’s treatment, there have been some further researches on the genus by Holttum (1940), Kiew (1990), Turner (1995), Clarke (2002), Adam et al (2005) Latiff et al (2011), Clarke and Lee (2012) and Latiff and Norsiah (2016) regarding the diversity, distribution, and ecological study of Nepenthes species and natural hybrids Another taxonomic study of the Peninsular Malaysian taxa was carried out by Rohana in 1988 that covers basic anatomical features and systematic study of the species and hybrids. Another taxonomic study of the Peninsular Malaysian taxa was carried out by Rohana in 1988 that covers basic anatomical features and systematic study of the species and hybrids. Turner (1995) listed ten species, which instead included two natural hybrids, namely N. × hookeriana and N. × trichocarpa, with N. alba and N. ramispina being excluded. Clarke (1999) added N. benstonei, a species known from Bukit Bakar, Kelantan, to the list and the latest was Adam and Hamid (2007) who described N. sharifah-hafsahii which happens to be a natural hybrid between N. gracilis and N. mirabilis rather than a true species (McPherson 2009)
