Antiostelma lantsangense (Tsiang & P. T. Li) P. T. Li; A. manipurense (Deb) P. T. Li; Dischidia obcordata (N. E. Brown) Maxwell & Donckelaar; Hoya lantsangensis Tsiang & P. T. Li; H. manipurensis Deb.

Subshrubs to 1 m, glabrous except for young parts and inflorescences. Stems and branches straw colored, striate. Petiole ca. 2 mm, with 2 or 3 glands grouped adaxially; leaf blade obtriangular or obovate, 2-3 × 1.5-2.5 cm, fleshy, subleathery when dry, base cuneate, apex retuse, rarely truncate; lateral veins obscure. Inflorescences sessile or subsessile. Pedicel 0.3-5.5 cm, pubescent. Sepals ovate-oblong, ca. 1.5 × 1 mm, hirsute. Corolla hirsute; tube ca. 6 × 3 mm; lobes triangular, ca. 1.5 × 1 mm, erect. Margins of corona lobes meet at middle. Anthers oblong, apical membrane acuminate, longer than corona lobes; pollinia nearly square; gynostegium shorter than corolla tube. Stigma head long, beaked at apex, exceeding anthers. Follicles linear-lanceolate, ca. 6.5 cm × 4 mm. Seeds oblong, ca. 3 × 1 mm; coma ca. 2 cm. Fl. Jul.

Montane forests, often attached to rocks or trees; 1000-1600 m. SW Yunnan [NE India, Myanmar, N Thailand]

Micholitzia was overlooked when Antiostelma was elevated by Li (Novon 2: 218. 1992) to the generic rank. The material from Thailand combines the characters used to separate the two species of Antiostelma, and it is not practical to recognize more than one species. Maxwell (Nat. Hist. Bull. Siam Soc. 39: 78-79. 1991) included Micholitzia in Dischidia, but this has not been followed as taxa of both genera differ markedly in habit and flower structure.
