Thelymitra tigrina, commonly called the tiger orchid[2] or tiger sun orchid,[3] is a species of orchid that is endemic to the south-west of Western Australia. It has a single narrow leaf and up to fifteen small yellow flowers with small brown spots.
Description
Thelymitra tigrina is a tuberous, perennial herb with a single leaf 100–150 mm (4–6 in) long and 3–4 mm (0.1–0.2 in) wide. Between two and fifteen yellow, cup-shaped flowers with many dark brown spots, 10–16 mm (0.4–0.6 in) wide are borne on a flowering stem 150–700 mm (6–30 in) tall. The sepals and petals are 5–8 mm (0.2–0.3 in) long and 3–5 mm (0.1–0.2 in) wide. The column is a similar colour to the sepals and petals, 3–4 mm (0.12–0.16 in) long, about 2 mm (0.08 in) wide and has short, white, pimply arms on the sides. The lobe on top of the anther is short and covered with small bumps. The flowers are self-pollinated and open on hot, sunny days. Flowering occurs from November to January.[2][3][4][5]
Taxonomy and naming
Thelymitra tigrina was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[6][7] The specific epithet (tigrina) is a Latin word meaning "of tigers",[8] referring to the colour of the flowers.[2]
Distribution and habitat
The tiger orchid grows in dense scrub in near-coastal, winter-wet scrub. It is found between Perth and Albany with a disjunct population near Esperance.[3][2][4][5][9]
Conservation
Thelymitra tigrina is classified as "not threatened" in Western Australia by the Western Australian Government Department of Parks and Wildlife.[9]
