Kata kunci: J enis bar u, Pulau Sumba, Schizostachyum purpureu m . INTRODUCTION Schizostachyum Nees is one of the native genus in Indonesia. Nees described the Schizostachyum for the first time in 1829 based on one species, S. blumei Nees ('blumii') (Dransfield, 1983; Yang et al., 2007). After that, many species have been described. There are 45 to 50 species of Schizostachyum distributed from South China through South East Asia to the Pacific (Widjaja, 1997). According to Dransfield & Widjaja (1995), there are 30 species of Schizostachyum in South East Asia, wild and cultivated mostly in lowland. It is suggested that there are ca. 24 species of Schizostachyum found in Indonesia (Widjaja, 1997). Widjaja & Karsono (2005) recognized 2 species of Schizostachyum from Sumba Island. Recently, Damayanto found another species during his exploration to Sumba Island. Although without inflorescence, this species can be recognized easily by its equal and subequal branchings (no dominant middle branch), leaf blade with conspicuous auricle, few bristles on leaf sheath, and purplish shoot blades. Since it can not be matched with other known member of the genus, it is proposed as a new species of Schizostachyum. Schizostachyum purpureum Damayanto & Widjaja, spec. nov. — Fig. 1. This species is similar to Schizostachyum bamban Widjaja (Widjaja, 1997) by its truncated apex of culm sheath, inconspicuous culm sheath and leaf sheath auricles. It can be distinguished from Schizostachyum bamban by its purplish green shoot; purplish, spreading and shorter culm sheath blade; serrate and glabrous leaf sheath ligules. — Type: Indonesia, East Sumba, TN Laiwangi-Wanggameti, Laiwangi area, along the road to Laputi Lake, 29 April 2016, Damayanto & Mahendra 143 [(Holotype BO! Accession No. BO−1935811! (culm sheath); BO−1935813! (shoot); BO−1935816! (leafy branch) ; K Isotype)]. Sympodial, densely tufted bamboo. Shoot purplish green with white hairs. Culms erect with pendulous tips, 5–6 m high, 4–5 cm diameter, internode 50–65 cm, walls thin, green, covered by white to light brown hairs at the node and has circular white wax. Branch complements subequal, develop about 2 m from ground. Culm sheaths up to 14.6–23 × 17.2 cm, not easily fall; margin of culm sheath with white to light brown hairs up to 1 mm long; apex truncated; auricles inconspicuous, glabrous or sometime with few bristle (1–5 mm long) at the outer end; ligule serrate, 1–2 mm high and glabrous; sheath blades purplish, concave and spreading, narrowly triangular, 13–17 × 1.2–2 cm, white to light brown hairs on the abaxial side. Leaves 21.5–26.6 × 3.5–4.0 cm, slightly pubescent beneath; leaf sheath auricle inconspicuous with few bristles 1–5 mm long; ligule serrate 1–1.5 mm high and glabrous. Inflorescences not seen. Distribution. This species is only known fr om the type locality in East Sumba, Lesser Sunda Islands. REINWARDTIA 120 [VOL.15 Habitat. Pr imar y for est and on the mar gin of the primary forest at 525 m alt. Vernacular Name. Au tamiang. Uses. This bamboo is used for making mat (gedeg) and flute (seruling). Notes. The epithet purpureum is based on the purplish shoot blade which is uncommon in the genus Schizostachyum. The similarity of S. purpureum and S. bamban can be seen at Table 1. This species also differs from S. castaneum Widjaja (Widjaja, 1997) because the latter has green shoots with densely brown to chestnut- colored shoots hairs; erect, concave, ovate-oblong culm sheath blade; auricle of the culm sheath ex- tend along to sheath apex up to the blade base, up to 2 mm high with bristles 4−11 mm long. Conservation Status. So far , only 2 clumps of this species have been found, one in the primary forest is still growing although very badly, the other in the primary forest margin has been cut off and left only 5 culms. So, a further study on this bamboo species should be done to ascertain its conservation status. Specimens Examined. Lesser Sunda Islands. Sumba Island: East Sumba, TN Laiwangi- Wanggameti, Laiwangi area, along the road to Laputi lake, Damayanto & Mahendra 143 (BO, K), 151 (BO). ACKNOWLEDGEMENTS The first author would like to thank E-WIN program of LIPI for the opportunity to join in the expedition to Sumba Island. Thanks also to Mr. Alex Sumadijaya, Mr. Taufik Mahendra, and Mrs. Dewi Rosalina for helping to collect the specimens. We also would like to thank the director of Taman Nasional Laiwangi-Wanggameti for the permission to enter the national park and to collect specimens, and for his assistance in sending them to Bogor. We sincerely thanks to Dr. Soejatmi Dransfield and Dr. Mien A. Rifai to review this manuscript. REFERENCES DRANSFIELD, S. & WIDJAJA, E. A. 1995. Introduction. In: DRANSFIELD, S. & WIDJAJA, E. A.
