Thelymitra paludosa


Thelymitra paludosa, commonly known as plain sun orchid, is a species of orchid that is endemic to Western Australia. It has a single erect, channelled, dark green leaf and up to ten or more blue to violet flowers. It grows in higher rainfall areas near the south coast.

Description

Thelymitra paludosa is a tuberous, perennial herb with a single erect, leathery, channelled, dark green linear to lance-shaped leaf long, wide with a purplish base. Between two and ten or more blue to violet, sometimes pink or white flowers wide are arranged on a flowering stem tall. The sepals and petals are long and wide. The column is pale blue to pinkish long and wide. The lobe on the top of the anther is dark brown to almost black with a yellow, slightly notched tip. The side lobes have toothbrush-like tufts of white hairs near their ends. Flowering occurs from mid-October to December.

Taxonomy and naming

Thelymitra paludosa was first formally described in 2013 by Jeff Jeanes and the description was published in Muelleria from a specimen collected near Esperance. The specific epithet is a Latin word meaning "swampy" or "marshy", referring to the habitat preference of this species.

Distribution and habitat

Plain sun orchid grows in high rainfall forests and around the edges of winter-wet swamps between Bunbury and Esperance.
