Australia has around 1,900 known orchid species, 90 per cent of which are endemic. The exquisite purple-and-yellow Cleopatra’s Needles Thelymitra apiculata is native to the south-west of Western Australia, where it grows in shrubland and woodlands around Geraldton. Classified as rare or near threatened, this orchid reaches 20 to 25 centimetres in height. The bright-yellow Tiger Orchid Diuris sulphurea grows in forest, woodland and grassland in all states and territories except Western Australia and the Northern Territory. Like other species in the genus it is known as a donkey orchid, after its elongated, droopy, ear-like petals. It reaches 20 to 60 centimetres in height.
