There are lots of interesting plants in the Stirling Range in addition to the orchids.
To the left is a type of plant known as a grass tree. It is in the family Xanthorrhoeaceae, a family of plants almost entirely confined to Australia. The family is related to the Lily Family (Liliaceae) and in a sense several genera in the family are an ecological counterpart to the yucca (genus Yucca) of the deserts of southwestern North America. This one is called Black Gin, Kingia australis. There is only one species in the genus and it is found only in southwestern Australia.
Above is southern cross, Xanthosia rotundifolia. It is a member of the family Apiaceae and so is related to parsnips, carrots, queen-anne's-lace, and a number of other North American wildflowers.
