Description: From Wikipedia: Habenaria dentata is a species of orchid native to the Himalaya, China, India, Indochina, Thailand and Myanmar. It is also found at Phalee.[1] The whole plant is about 35 to 80 cm in height. It has a smooth round tuber that give rise to a single plant. Lower part of stem sheathed, middle leafy and upper part bracteate. Leaves 4 to 6 cm long, oblong to elliptic, 5 nerved, sometimes 7 also, the base of the leaf narrowed into a long tubular sheath. Spike 4 to 8 cm long, laxly flowered. Sepals sub-equal, broadly ovate, acute, spreading, the lateral pair sub-erect. Petals narrowly oblong, sub-acute, curved inwards, shorter than the sepals. Lip as long as the sepals, variable in breadth, with large cuneate or rounded, fimbriate or crenate side lobes and a small oblong entire apical lobe. Spur infundibuliform at the base, slender laterally compressed, geniculte, sub-clavate below the knee, longer than the shortly stalked beaked ovary. Stigmas separated by the area in the centre by the orifice of the spur.[2] It generally blooms in August- September.[3] https://en.wikipedia.org/wiki/Habenaria_dentata

Culture: Terrestrial orchid, grown in peat-based soil mix, kept moist until winter, when the leaves die back. I start watering again in late February. It's kept outside next to my north-facing wall.
