Ying.Roots 1–3 cm, 0.5–1 mm in diam., radiately appressed tosurface of branches. Stem abbreviated, with 2–4 small leaves.Leaf blade narrowly oblong, oblanceolate, or linear, 5–15 × 1–3mm, subleathery, acute to acuminate. Inflorescences often 2 or3, erect or ascending, few flowered; peduncle 1.5–2.5 cm,winged, with many sterile bracts; sterile and floral bracts ovate,slightly conduplicate, 2–3 mm. Flowers green; pedicel andovary yellowish green, 1–1.8 mm. Sepals and petals 1.4–2 mm,connate at base forming a tube, free apical lobes 1–1.5 mm, triangular-lanceolate,those derived from sepals dorsally carinateand from petals clawed at base; lip including basal spur to 3mm, broadly ovate, obscurely 3-lobed, basal margin incurved,apex with a reversely hooked linear appendage; spur saccateglobose,ca. 1 mm in diam. Fl. Jan–Feb.Epiphytic on trees in coniferous or broad-leaved forests; 1000–1600 m. C Taiwan [Philippines].190. GROSOURDYA H. G. Reichenbach, Bot. Zeitung (Berlin) 22: 297. 1864.火 炬 兰 属 huo ju lan shuChen Xinqi ( 陈 心 启 Chen Sing-chi); Jeffrey J. WoodHerbs, epiphytic, small, monopodial. Stems very short, enclosed in basal leaf sheaths. Leaves few to several, basal, distichous,flat, narrowly oblong to lanceolate, jointed and shortly sheathing at base, apex often unequally bilobed. Inflorescences lateral, usuallyshorter than leaves, often many borne simultaneously on a plant; peduncle longer than rachis, slender, both usually prickly-hairy,with 1 or 2 flowers open at a time; rachis usually thickened, rather short; floral bracts persistent. Flowers ephemeral, opening widely,to 1.5 cm in diam. Sepals and petals free, similar, spreading. Petals narrower than sepals; lip movably attached to end of column foot,spurred, ± 3-lobed; lateral lobes erect, narrow; mid-lobe often replicate on spur, sometimes with 2 basal lobules on both sides, with asmall median tooth, giving a “4-lobed” appearance; spur broad, usually spreading forward, rarely pendulous. Column elongate,slender, bent forward at an obtuse angle at stigma base, with a rather long foot; rostellum elongate; pollinia 2, waxy, subglobose,entire, each with a caudicle attached by a common cuneate or triangular-cuneate stipe to a small triangular viscidium.About ten species: India (Andaman Islands), Myanmar, Thailand, and Indochina to Malaysia, Indonesia, and the Philippines; one species inChina.1.

Leaves usually 3–6, basal; leaf bladefalcate-oblong, 7–10 × 1.4–1.9 cm, somewhat fleshy, baseattenuate, apex acute and unequally bilobed. Peduncle andrachis densely minutely black hispid; peduncles 2–5, 3–4 cm;rachis laxly 2- or 3-flowered; floral bracts ovate-triangular, verysmall, fleshy, abaxially hairy. Flowers small, yellow with brownspots; pedicel and ovary ca. 4 mm. Sepals ovate-oblong, ca. 3 ×2 mm, acute; lateral sepals: basal 2/3 of width adnate to columnfoot. Petals oblong, ca. 3 × 1 mm, obtuse; lip spurred, 3-lobed;lateral lobes erect, narrowly oblong, ca. 3 mm, rounded andcurved backward; mid-lobe with a very small apical lobule and2 erect basal lobules; basal lobules parallel to lateral lobes, butshorter and broader; spur ca. 3 mm, almost continuing line ofcolumn foot. Column ca. 2 mm, winged, foot ca. 0.5 mm. Fl.Aug.Epiphytic on tree trunks in evergreen broad-leaved forests.

Leaves few, linear-falcate or strap-shaped, flat,jointed and sheathing at base. Inflorescence lateral, often pendulous, racemose, rather long, few to many flowered, a few flowersopen at once or all open together; peduncle short; rachis terete, sometimes clavate, fleshy, sulcate; floral bracts small. Flowers rathershort-lived or lasting for ca. 1 week, to 9 mm in diam., white, yellowish, or greenish with various purple, brownish purple, or redmarkings, slightly fleshy.
