Thelymitra fuscolutea – Chestnut Sun Orchid
This orchid was named by Robert Brown in 1810 from specimens collected at King George Sound by Ferdinand Bauer in January 1802. It was, for some time, regarded as a form of the more common and widespread Leopard Orchid, Thelymitra benthamiana.
Thelymitra stellata – Star Orchid
This species was named by John Lindley in 1840 from specimens collected by James Drummond in 1839. It was then reduced to a variety of the Chestnut Sun Orchid, Thelymitra fuscolutea but, following a more recent revision, has once again been recognised as a species.
Thelymitra benthamiana – Leopard Orchid
First collected by James Drummond in the 1840s and named by Heinrich Reichenbach in 1871 it was confused for a long time with the less common Chestnut Sun Orchid, Thelymitra fuscolutea.
Thelymitra dedmaniarum – Cinnamon Sun Orchid
Discovered at Gidgegannup by B. T. Goadby in 1931 and for some time was thought to be a form of Thelymitra stellata.
Thelymitra magnifica – Crystal Brook Star Orchid
Although recognised for many years, this orchid was considered to be a form of the Star Orchid, Thelymitra stellata. However its flowering period is earlier and the crest at the top of the column is intermediate in size between that orchid and another closely related species, Jackson’s Sun Orchid, T. jacksonii.
