Kunci identi- fikasi pada jenis A ppendicula seksi Pododesme, peta persebaran, dan foto telah dibuat untuk keperluan identifikasi jenis. Kata kunci: A ppendicula, Flor es, Indonesia, jenis bar u, seksi Pododesm e, Su mba Timur . INTRODUCTION The genus A ppendicula was established by C. L. Blume (1825), is characterized by having the lip joined to the column foot, six pollinia, and usually with an appendage on the upper surface of the labellum pointing towards the base (Wood, 2003). The genus contains approximately 150 species distributed from India to Taiwan, and through Indonesia, Philippines, New Guinea to the Pacific (Seidenfaden & Wood, 1992; e-monocot, 2017). Indonesia has ca. 54 species of A ppendicula. Thirty-five species have been reported from Sumatra (Comber, 2001) and 19 from Java (Comber, 1990). A species of A ppendicula was collected from four localities in Sumba Timur, Flores, Sumbawa, and Sulawesi Tengah simultaneously, grown in Bali Botanic Garden (Bali BG) and its herbarium specimens were stored at Herbarium Bogoriense (BO). The species belongs to section Pododesme, and, using literature and herbarium collections (BO), was found to differ from any known species in this section. This novelty is described below completed with the line drawing, ecological information, photos, and identification key to the species. MATERIALS AND METHODS Living specimens in Bali Botanic Garden were examined of the following species: A ppendicula cordata (E200610271; E20060663; E199710152; E200207125; E200010232; E20060613; E198006128); A . cristata (E197710100); A . elegans (E197806708). Herbarium materials in Herbarium Bogoriense were examined of the following: A ppendicula cordata (BO 1817838; BO 1817839); Appendicula infundibuliformis (BO 0047009); Appendicula longa (BO 0046265). Of species otherwise unavailable the protologues were studied (Reichenbach, 1875; Schlechter, 1912; Schlechter, 1914; The plant list, 2017; e-monocot, 2017). Morphology was examined using a dissect- ing microscope.

Stem tufted, arching‒pendulous, branched, slightly flattened, 14‒50 cm, ca. 3 mm in diam., internodes 0.7‒1.5 cm, completely enclosed in tubular leaf sheaths. Leaves many, distichous, alternate, twisted at the base, blade ovate-elliptic, 1‒2.5 × 0.5‒1.2 cm, base with tubular sheaths, articulate, apex unequally bilobed with a small mucro. Inflorescence terminal and lateral, up to 21 cm long, branched with up to 7 branches, 1-10 flowers on each rachis but with only 1-3 flowers open at a time, peduncle 3.5‒16 cm long, rachis 1‒4 cm long; floral bracts ovate- lanceolate, apex acuminate, distichous, 4 × 1.5 mm, green-purple. Pedicel with ovary 4‒5 mm long, white-purplish. Flowers 4‒5 mm diam., 7 mm long, facing forwards, white with purple flushes, translucent, successive. Dorsal sepal ovate, apex sub-acute, 4 × 2.5 mm. Lateral sepals oblique, ovate-oblong, 6‒6.5 × 3‒4 mm; mentum saccate, yellowish nectar often occur, obtuse, ca. 2 mm long. Petals oblong, truncate-obtuse, 3 × 2‒3 mm. Lip concave, broadly oblong when spread out, apex acuminate reflexed 180° to the right, apex irregularly caudate when flattened, margin entire, 6 × 4.5 mm, white with purple flushes on the tip; the appendage extending from the hypochile to the mesochile, forming 2 incurved ridges, erect, cordate, saccate. Column white, translucent, 5 × 1.5 mm; pollinia 6 in 3 pairs, unequal, truncate, yellow; anther cap white, 1.5 mm long; rostellum bidentate, concave.

Flower ing in cultivation thr oughout the year. Cultivation. Appendicula cordata grows epiphyti- cally. Good air circulation and moderate light intensity, ca. 50-80 %, should be provided. Temperature 15°C - 25°C. Conservation status. Not assessed. Other materials examined. Indonesia, Nusa Tenggara Timur: Flores, Ruteng, Ranamese Lake – Longe Hill, cult. Bali Botanic Garden E20060663 (leg. Mahyar & Nurdin 060); Nusa Tenggara Barat: Sumbawa, Mt. Ujung Samu, Tepal, Batulante, Deden Girmansyah et al. Deden 293 (BO 1817838, BO 1817839); Sulawesi Tengah: Gunung Dako, cult. Bali Botanic Garden E200010232 (leg. Bayu Adjie et al. BA 95). Notes. The habit of Appendicula cordata is similar to that of A . infundibuliformis J. J. Sm. The new species differs from that species, and all other species in sect. Pododesme, by the lip apex being twisted to the right, much like A . ovalis (Schltr.) J. J. Sm. in section Oligodesme. In addition, A. infundibuliformis has yellowish - green flower, a flat lip, and a horseshoe-shaped appendage, whereas A . cordata has white flowers with purple markings, a concave lip, and a cordate appendage. The other species in sect. Pododesme do not have long (to 16 cm), branching, pendulous inflorescences like A . cordata. CONCLUSION A new species described from Sumba, Sumbawa and Flores in the Lesser Sunda Islands shows that many new species from the under collected areas in Indonesia await discovery. This species is one of the species collected and grown ex-situ that represents small number of species from the area. This new species is distributed in Flores, Sumba, 1 a.

Thus, complete information on distribution and conservation status in nature on this newly described species and other species within the genus A ppendicula are needed to finish the checklist of Orchids of Indonesia.
