Mapania multiflora, a distinctive new species of Cyperaceae (Mapanioideae) from Borneo

Abstract

Summary. Mapania multiflora is described and illustrated. It is vegetatively similar to taxa with broad leaves and pseudopetioles, such as M. cuspidata. However, it is reproductively similar to sect. Thoractostachyum with a paniculate inflorescence and furrowed fruit. The DNA is similar to M. bancana in sect. Thoractostachyum, in the three sampled cpDNA regions: atpH-F, trnL-F and psbA-trnH. However, it is identical to none of these due to its unique combination of vegetative, reproductive and molecular characteristics.

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.…”

Two New Species and One New Geographical Record for Sarawak, Malaysia (Cyperaceae: Mapanioideae)

“…The diversity of Mapania species in Sarawak is tremendous, with 31 out of 71 world's total number are recorded includes three newly described species; M. sapuaniana Shabdin (2013a); M. multiflora Shabdin (2013b), M. meekiongii and M. kadimiana Shabdin, Meekiong & Miraadila (Shabdin et al, 2016). Our recent field excursions collected many interesting specimens that morphologically not matching with the existing species recorded for Sarawak.…”

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

“…This family currently includes two subfamilies, Mapanioideae and Cyperoideae (Govaerts et al, 2007;Muasya et al, 2009), with genus Mapania being under subfamily Mapanioideae. 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).…”

“…M. sapuaniana for example, has so far only been recorded in a small area at Sungai Joh (approx. 3 km radius) of Lanjak Entimau Wildlife Sanctuary (LEWS) (Shabdin et al, 2016), while M. ballehensis, M. kipas and M. mirae are recorded only from Baleh National Park. In many field expeditions conducted since 2008, the effort of collecting living specimens to be planted in our arboretum has failed, although the collection includes preserving some soil of the species original habitat.…”
