INTRODUCTION Cyperaceae are the third largest in the monocotyledon family and seventh largest in the angiosperms with 106 genera and 5,387 species (Govaerts et al., 2007). They form a huge, morphologically diverse, geographically wide- spread, ecologically and economically important family (Naczi, 2005). Nevertheless, there are many species which are narrowly distributed, specific to certain habitats and of conservation concern (Naczi & Ford, 2008). The difficulty of assessing levels of endemism was noted by Goetghebeur (1998), due to the lack of recent revisions and reli- able checklists as many species are known from only a single specimen or locality (Shabdin & Meekiong, 2012). All members of Cyperaceae in general are problematic to identify, due to the lack of good discontinuous morphological characters. Asian species, especially, show a wide range of morphological variation, where the appearance of the whole inflorescence changes as it matures, alt- hough individual structures remain constant in shape and size (Simpson, 1992; Shabdin et al., 2013a). 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 (Miraadila & Shabdin, 2016) 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. Among many specimens, three were confirmed; two as a new species and another one was a new record from Sarawak. All the three species are presented here. MATERIALS AND METHODS Botanical collections were conducted from April to December 2014 which covers various localities from western to eastern parts of Sarawak. Sample collections and herbarium specimens’ preparation were made accordingly to the standard Herbarium Specimen Collection (Bridson & Forman, 1992). Samples identification REINWARDTIA 130 [VOL.15 and verification were conducted at the Herbarium of Sarawak Forest Department (SAR) and Herbarium of Universiti Malaysia Sarawak. THE NEW SPECIES 1. Mapania hidiriana Miraadila, Shabdin & Meekiong spec. nov. Fig. 1. — Type: Malaysia, Sarawak, Miri Division, Wilma Oil Palm Plantation, fragmented forest, May 2015, Hidir M. et al. MY0078 (Holotype SAR!; Isotype Herbarium of Universiti Malaysia Sarawak). Similar to M. meditensis and M. cuspidata in term of appearances by having petiolate and oblong- lanceolate leaves. The new species can be differentiated by absences of culm (vs. presence in M. cuspidata) and elongated lanceolate inflorescences (vs. elliptic and always obscured in the leaf sheath in M. meditensis). Slightly robust, rhizomatous, rhizome 5–7 cm long, 3–4 mm diam. Cataphylls present; 8–10; 1– 10 × 1–2 cm, yellowish green or greenish and becoming light brown and papery when dry. Culm absent. Leaves petiolate, strongly 3-ranked, up to 55 cm long, leaf-blade oblong, oblong-lanceolate, 28–50.5 × 4–6.5 cm, apex abruptly narrowed, obtuse to rounded, cuspidate to long cuspidate, 5– 8 cm, base abruptly narrowed into pseudopetiole, coriaceous, 3-nerved, secondary nerves distinctly, septate-nodulose when dry, margins entire at first and slightly serrulate toward the apex, pseudo- petiole present, longer than leaves, 33–52 cm, channelled along; 1/3 of the lower part gradually developed into sheath, 5–8 cm wide, margins with thin yellowish green layer, slightly wavy. Inflorescence sessile, up to 30 inflorescences or more per plant, ovoid or elongated lanceolate, 2–5 cm long, 4–8 mm diam. Light brown to brown, lower bract shorter, 6–8 × 4–6 mm, spicoid bracts 14–16 × 3.5–4 mm, floral bracts 6, free, lowest 2 bracts oblong, 14–16 × 2 mm, obtuse, light to mid brown, striate with brownish, keel, narrowly winged, upper bracts linear, 14–5 × 1 mm, acute, glabrous; staminate flower 1–2 per spicoid, anthers linear oblong, up to 6 mm long or more; filament 12–14 mm long, stigma branches 3, style 3 mm long. Fruit not seen. Ecology and distribution. Fr agmented for est in the oil palm plantation. Sarawak, Borneo. Etymology. The epithet name is given after Hidir Marzuki, laboratory assistant and plant collector in Universiti Malaysia Sarawak who collected the type specimen. Specimen examined. Malaysia, Sar awak, Mir i Divison, Suai, Wilma oil palm plantation, fragmented forest, May 2015, Hidir M. MY 0078 (Type specimen). Notes. Mapania hidiriana might be superficially confused with other petiolate-leaved species such as M. cuspidata, and M. meditensis because the inflorescences are hardly seen and sometimes sub- terranean. Conservation status. The status of this species is unknown since we collected it from a single locality. 2. Mapania sembilingensis Miraadila, Shabdin & Meekiong spec. nov. Fig. 2. — Malaysia, Sarawak, Limbang Division, Bukit Sembiling Recreation Park, hill mixed dipterocarp forest, on the slope, Dec 2014, Miraadila, M. I., Meekiong, K. & Burhanuddin MY0065 (Holotype SAR!; Isotype Herbarium of Universiti Malaysia Sarawak). In common with M. multiflora, but has a distinct slender and short culm with capitate inflorescence (vs. long culm with paniculate inflorescence in M. multiflora). Fruits obovoid shape with short apiculate apex (vs. broadly ellipsoid fruits in M. hispida). Moderately robust, rhizomatous, rhizome 3–6 cm, 4–5 cm diam., stilt roots sometimes present.

Lowland mixed dipterocarp forest at altitude 50–100 m, on the slope and wet place near the stream. Borneo (Sarawak), so far only recorded from the type locality (Bukit Sembiling) in Limbang. Etymology. Named for Gunung Sembiling, Limbang, the type locality. Specimen examined.

Notes. Closely r elated to M . m ultiflora, M . sembilingensis has a capitate inflorescence while M. multiflora has a paniculate inflorescence. The hispid culm might be confused with M. hispida but the fruit differs by its obovoid shape with a short apiculate apex, while the fruit of M. hispida is usually broadly ellipsoid. Conservation status. The status of this species is unknown since we collected it from a single locality. THE NEW RECORD MAPANIA SPADICEA Uittien, Fig. 3. – Rec. Trav. Bot. Neerl. 33: 150 (1936); D.A.

Involucral bract several, glumaceous, lanceolate, 1.4–3 × ± 0.8 cm, acute, coriaceous, greenish at first becoming dark brown, somewhat scabrid, nerves indistinct. Inflorescence terminal, composed of 1 spike, spike elliptic to lanceolate, 2.5–5 × 1–1.3 cm, acute to subobtuse, brown; spicoid bracts lanceolate, 13–14 × 2.2–4 mm, obtuse, sub- coriaceous, often splitting from the base, mid-brown, glabrous, nerves indistinct; floral bract 6, free, lowest 2 bracts linear to linear lanceolate, 12.8–13.7 × 0.3–0.7 mm, acute, flat to somewhat keeled, sometimes sparsely hispid on margin; staminate flowers 3 per spicoid, anthers linear, 5–8 mm long, stigma branches 3, style 6 mm long.

Ecology and distribution. Mixed dipter ocar p forest, on slope in gully, clay loam soils. Borneo (previously recorded only from Brunei and Kalimantan) Specimen examined. Malaysia, Sar awak, Sibu Division, Sg Apeng, Sibu–Bintulu Road, M. I. Miraadila, B. Bourhanudin & K. Meekiong, MY0068 (Herbarium of Universiti Malaysia Sarawak); Brunei, Temburong, tributary of Sungai Temburong, Machang, 19 Aug. 1990, W ong WKM1962 (K!). Indonesia, Kalimantan, W Kutai, Long Temelen, 26 Aug 1925, Endert 2874 (K!, SING!). Notes. A new r ecor d for Sar awak. This species is similar to M. angustifolia and M. kadimiana in having strongly 3-ranked leaves with chocolate brown sheaths but can be differentiated by the single spike per culm. Conservation status. The populations at Sg Apeng, on the Sibu–Bintulu road, is close to the roadside and the areas surrounded by agricultural activity. It is believed that these populations may soon be gone. Since the species was described from Kalimantan it may have been expected that it would also be found in Sarawak. DISCUSSSION The study of the Mapania in Sarawak is far from complete. Available data have mostly come from coastal and accessible areas, whereas mostly the inland areas, particularly along the Kalimantan border are still in cryptic. With the discovery of these two taxa, the number of Mapania in Sarawak now has increase to 32 species. It is believe that the number of Mapania species in Sarawak may increase up to 40 species as many specimens are yet to be identify and many more in the forest are still awaiting for discovery.
