Thelymitra spadicea, commonly called the browntop sun orchid, is a species of orchid that is endemic to Tasmania. It has a single erect, fleshy leaf and up to four relatively small blue flowers with small darker spots and an elongated lobe on top of the anther.
Description

Up to four blue flowers with small darker spots, wide are arranged on a flowering stem tall. The sepals and petals are long and wide. The column is bluish white, about long and wide. The lobe on the top of the anther is brown with a blue band, a yellow elongated tip and small teeth. The side lobes have dense, mop-like tufts of white hairs.

Taxonomy and naming
Thelymitra spadicea was first formally described in 1999 by David Jones from a specimen collected near Stanley and the description was published in Australian Orchid Research. The specific epithet is a Latin word meaning “of a light brown colour", referring to the colour of the anther lobe.
