Dinochloa malayana S.Dransf. (Poaceae: Bambusoideae), rekaman baru untuk Indonesia. Reinwardtia 17(1): 35‒37. ‒‒ Persebaran Dinochloa malayana sebelumnya hanya diketahui di Semenanjung Malaysia dan Thailand bagian Selatan. Namun, baru-baru ini, bambu ini ditemukan juga di Pulau Karimun Anak dan P. Batam, Indonesia. Deskripsi, catatan dan foto jenis ini disajikan. Kunci identifikasi Dinochloa Sumatera juga disajikan. Kata kunci: Dinochloa malayana, Pulau Batam, Pulau Karimun Anak, rekaman baru. INTRODUCTION Dinochloa malayana S.Dransf. was first described by Soejatmi Dransfield in 1996 with Ridley 3112 as the type specimen, augmented with a description of the culm leaves based on Dransfield SD915a. Before Dransfield (1996a), Holttum (1958) had recognized two different taxa of Dinochloa in Peninsular Malaysia; he enumerated these as D. scandens (Blume) Kuntze (represented by Ridley 3112) and an unidentified Dinochloa species. Subsequently, Dransfield (1991) has clarified that the Dinochloa found in Peninsular Malaysia had been wrongly identified as D. scandens (which she stated was found only in Java, Indonesia). Dransfield & Widjaja (1995) also mentioned that D. scandens is only found in West Java, and that the record of its occurrence in other parts of South East Asia are erroneous. The specimens cited by Holttum (1958) as "Dinochloa scandens" have been re-diagnosed as a distinct species, named D. malayana by Dransfield (1996a). According to Dransfield (1996a; 1996b), Turner (1995-1996), Chua et al. (2005), Neamsuvan & Tanthien (2015) and Vorontsova et al. (2016), the distribution of D. malayana only included Peninsular Malaysia and Southern Thailand. How- ever, during a 2017 expedition conducted by the Research Center for Biology – LIPI, this species was found at Karimun Anak Island in the administration area of Kepulauan Riau Province, Indonesia. Additionally, this species has also been found on Batam Island (in the administration area of Kepulauan Riau Province), with the collection Widjaja 4099 (BO) on 20 March 1991. Widjaja (1991) had identified the W idjaja 4099 as D. scandens and later Soejatmi Dransfield annotated this collection as D. aff. malayana in 1998. The specimens seem incomplete (without culm sheath blade), so its precise identity had been uncertain. The similarities to D. malayana include the young shoot covered by white wax, solid and small-diameter culms (less than 2 cm), culm-sheaths up to 8.4 × 3.6 cm, inconspicuous and glabrous culm-sheath auricles, entire and glabrous culm-sheath ligule, small leaf-sheath auricles (less than 1 mm long) with bristles, and entire and glabrous leaf-sheath ligule. Although flowers are absent, Dinochloa species can be differentiated by vegetative characters (Dransfield, 1996a). Widjaja (2017, pers. comm.) was the one who informed me that D. malayana exists in Batam Island. Better material has been collected, including complete culm-sheath with blades (Fig. 1.), it is possible to verify the identification as Dinochloa malayana, here formally newly recorded for Indonesia. An identification key to the two known Sumatran Dinochloa species is also presented, as the Kepulauan Riau Province belongs to the Sumatra area. These two species are D. glabrescens Widjaja (Widjaja, 1997) from REINWARDTIA 36 [VOL.17 Lampung and D. malayana from Karimun Anak Island and Batam Island. TAXONOMIC TREATMENT DINOCHLOA MALAYANA S.Dransf. ‒ Kew Bull. 51(1), 1996: 110. Type: Peninsular Malaysia, Ridley 3112 (holo K!; iso SING). Sympodial bamboo, climbing or twining on other plants up to 6 m high. Shoots green with purple or maroon culm-sheath, covered with white hairs and white wax, rough but becoming smooth when mature. Culms zig-zag, green, diameter 1–2 cm, internode 10–15 cm long, solid or with a small lumen; nodes frequently producing roots when in contact with or near to the ground. Branch complement with one dominant branch surrounded by several smaller higher-order branches; dominant branch up to 3 m long or more. Culm-sheath 7.8–8.4 × 3–3.6 cm, caducous, purplish, auricles inconspicuous and glabrous; lig- ule entire, up to 1 mm high and glabrous; blades early caducous, purplish green, lanceolate, 5–6.5 × 0.5–1 cm, erect at first then deflexed. Leaves 15.1– 25 × 2–4 cm, leaf-sheath auricles small, less than 1 mm high with bristles 0.5–0.7 mm long; ligule en- tire, less than 1 mm high and glabrous. Inflorescence not seen. 1 a.

Peninsular Malaysia, Souther n Thailand and Indonesia (Karimun Anak Island and Batam Island, Kepulauan Riau Province). This spe- cies has been planted in the Bogor Botanic Garden and Batam Botanic Garden. Ecology. This species gr ows wild in distur bed primary forest on Karimun Anak Island at an altitude of 60 to 105 m, and along the main road, near a small stream on Batam Island. As this bamboo is not abundant at Karimun Anak Island, it could be vulnerable to logging disturbance. Specimens examined.

This bamboo is not utilized by the local people at Karimun Anak Island. Based on Neamsuvan & Tanthien (2015), D. malayana was used to heal menstrual dysfunction in Thailand by drinking a decoction of the leaves. ACKNOWLEDGEMENTS I would like to thank the Head of the Research Center for Biology – LIPI and the Head of the Herbarium Bogoriense (BO) for opportunity to join the expedition to Karimun Island and Karimun Anak Island, as well as for providing facilities for my studies. The Head of Bogor Botanic Garden is gratefully thanked for expedition funding. Thanks also go to Mrs. Dewi Susan (BO) for her hospitali- ty during the expedition. The Forestry Ministry kindly granted permits for plant collection. Many thanks are due to Prof. Dr. Elizabeth A. Widjaja for critically reading the manuscript. REFERENCES CHUA, L. S.
