The sepals and petals are similar to each other and the labellum has three spreading lobes and a yellow callus.

Description[]

Calanthe triplicata is a terrestrial, evergreen herb that grows in clumps and has crowded, fleshy, oval pseudobulbs 40–80 mm (2–3 in) long and 20–40 mm (0.8–2 in) wide. Each pseudobulb has between four and nine dark green, lance-shaped, corrugated leaves 250–900 mm (10–40 in) long and 60–180 mm (2–7 in) wide tapering towards the base. The leaf veins are more or less parallel with between six and nine more prominent than the rest. Between eighteen and forty white flowers 25–35 mm (0.98–1.4 in) wide are crowded near the top of an upright flowering stem 50–1,500 mm (2–60 in) long. The sepals are egg-shaped, 6–19 mm (0.2–0.7 in) long and 6–7 mm (0.2–0.3 in) wide. The petals are a similar shape, 5–15 mm (0.2–0.6 in) long and 2–6 mm (0.08–0.2 in) wide. The labellum has three widely spreading lobes 4–15 mm (0.2–0.6 in) long and 2–6 mm (0.08–0.2 in) wide with the middle lobe further divided into two. The spur behind the labellum is 10–30 mm (0.4–1 in) long and curved. Flowering occurs from October to February in Australia and in April and May in China.[2][3][4][5]

Taxonomy and naming[]

The common Christmas orchid was first formally described in 1796 by , who gave it the name Orchis triplicata and published the description in Paul Usteri's book Annalen der Botanick.[6][7] In 1907, Oakes Ames changed the name to Calanthe triplicata.[1] The specific epithet (triplicata) is derived from the Latin prefix tris meaning "thrice"[8]: 798  and plicatus meaning "folded".[8]: 619
