Corymborkis veratrifolia

Corymborkis veratrifolia is a terrestrial, evergreen herb that forms clumps and has thin rhizomes and thin, upright, unbranched, wiry stems 0.5–1.5 m (2–5 ft) tall. There are between six and fifteen narrow elliptic leaves 200–300 mm (8–10 in) long and 70–100 mm (3–4 in) wide. The leaves are dark green, thin-textured and corrugated. Between twenty and sixty short-lived, cinnamon-scented flowers are crowded along the branched flowering stem, the flowers 20–25 mm (0.8–1 in) wide. The sepals are green, linear to lance-shaped or spatula-shaped, 32–38 mm (1.3–1.5 in) long and 2–3 mm (0.08–0.1 in) wide. The petals are white, 25–30 mm (0.98–1.2 in) long, 3–4 mm (0.1–0.2 in) wide and wavy. The labellum is pale white, 20–25 mm (0.8–1 in) long and 8–12 mm (0.3–0.5 in) wide with a narrow tube-shaped base and a broad egg-shaped end with wavy edges. Flowering occurs between December and March in Australia, December to July in New Guinea and in July in China.[2][3][4][5]

The white cinnamon orchid was first formally described in 1825 by Caspar Georg Carl Reinwardt who gave it the name Hysteria veratrifolia and published the description in Sylloge Plantarum Novarum Itemque Minus Cognitarum a Praestantissimis Botanicis adhuc Viventibus Collecta et a Societate Regia Botanica Ratisbonensi Edita.[6][7][8] In 1859 Carl Ludwig Blume changed the name to Corymborkis veratrifolia.[1][9] The specific epithet (veratrifolia) is derived from the Latin words veratrum meaning "hellebore"[10]^:832 and folia meaning "leaves".[10]^:466

Corymborkis veratrifolia grows in shady places in forest and rainforest in China, Taiwan, Cambodia, India, Indonesia, the Ryukyu Islands, Laos, Malaysia, Myanmar, Sri Lanka, Thailand, Vietnam, islands in the south west Pacific and northern Australia. In Australia it is found between the Iron Range and Airlie Beach in Queensland.[2][3][5]
