Mapania sapuaniana (Cyperaceae), a new sedge species from Sarawak

Abstract

Mapania sapuaniana, a spectacular new sedge species from Lanjak Entimau, Sarawak, is described and illustrated. It is closely related to M. richardsii and M. borneensis but differs in having broad leaves with a distinct pseudopetiole, reddish purple or maroon coloration on the underside of the leaf and petiole and an inflorescence composed of several spikes.

Evaluating the Ecophysiology of Survival for Mapania Cuspidata (Miq.) Uittien (Cyperaceae) Transplantation

“…During the course of 130 days post-transplanting, M. cuspidata developed an average of 7.7 new leaves with leaf production rate of 15.8 days/leaf. The findings of this study are substantial yet confounding given extensive reviews on Mapania species being shade loving plants that grow well in conditions of damp and wet soils (Simpson, 1992;Shabdin et al, 2013aShabdin et al, , 2013bMiraadila et al, 2016a) and failing attempts to plant the species in new locations (Z. Shabdin, pers.…”

“…The diversity of Mapania species from Sarawak is tremendous, with 31 out of 71 world's total number are recorded (Miraadila et al, 2016). Studies on Mapania of Sarawak since 2008 by Shabdin et al (2013aShabdin et al ( , 2013bShabdin et al ( , 2016 has observed the high tendency of endemicity of the species to Borneo (M. longiflora, M. angustifolia, M. lorea, M. debilis, M. maschalina, M. obscuriflora, M. richardsii, M. borneensis, M. latifolia and M. hispida), and hyper-endemicity (M. foxworthyi, M. graminea, M. sapuaniana and M. multiflora). Only a few species are widespread; for instance, M. cuspidata.…”

A New Mapania Species (Cyperaceae) from Sarawak, Malaysia

“…The studies of genus Mapania in Borneo and particularly Sarawak has been neglected since the last enumeration by Simpson (1992) until Shabdin et al (2013aShabdin et al ( & 2013b added two new species and another three recently, with one new record (Miraadila & Shabdin, 2016) to the list making it 31 species in total. In attaining the important knowledge of this valuable genus, a comprehensive research has been conducted to study the delimitation of the genus in Sarawak.…”

“…The number however has increased as several new species been discovered recently, particularly from Malesian region i.e. Shabdin et al (2013aShabdin et al ( & 2013b, and Miraadila and Shabdin (2016). Mapania section Pandanophyllum is endemic to Asia, Indomalesia, Australia and the Pacific Islands.…”
