Thelymitra frenchii |
Thelymitra frenchii, commonly called the scarp sun orchid [1] or Jarrahdale sun orchid, [2] is a species of orchid in the family Orchidaceae and endemic to a small area in the south-west of Western Australia. It has a single long, fleshy leaf and up to three relatively small, blue flowers.
Thelymitra frenchii is a tuberous, perennial herb with a single channelled, fleshy, pale green, linear to lance-shaped leaf 60–120 mm (2–5 in) long and 5–12 mm (0.2–0.5 in) wide. Up to three blue flowers, 18–25 mm (0.7–1 in) wide are borne on a flowering stem 50–140 mm (2–6 in) tall. The sepals and petals are 8–12 mm (0.3–0.5 in) long and 3.5–6 mm (0.1–0.2 in) wide. The column is bluish to pinkish, about 5 mm (0.2 in) long and 3 mm (0.1 in) wide. The lobe on the top of the anther is 2–3 mm (0.08–0.1 in) long and about 2 mm (0.08 in) wide, mostly yellow with a narrow purplish band and a broad, shallow notch. The side lobes have toothbrush-like tufts of white hairs. The flowers remain open even in cool weather and until late in the day. Flowering has only been observed in October. [1] [2] [3] [4]
Thelymitra frenchii was first formally described in 2004 by Jeff Jeanes from a specimen collected near Jarrahdale and the description was published in Muelleria. [5] The specific epithet (frenchii) honours "Christopher (Chris) J. French" for his assistance to the author. [3]
The scarp sun orchid grows in soil pockets on granite outcrops in jarrah forest. It is only known from near Jarrahdale in the Jarrah Forest biogeographic region. [3] [6]
Thelymitra frenchii is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife. [6]
