One or two pale creamy-green flowers Шаблон:Convert wide are borne on a wiry flowering stem Шаблон:Convert tall. The dorsal sepal is Шаблон:Convert long, Шаблон:Convert wide, oblong to elliptic near the base then tapers to a glandular tip Шаблон:Convert long. The lateral sepals are lance-shaped near their bases, Шаблон:Convert long, Шаблон:Convert wide and taper to narrow glandular tips slightly shorter than that on the dorsal sepal. The petals are Шаблон:Convert long, Шаблон:Convert wide, lance-shaped near the base then taper to a thin, sometimes glandular tip.

Taxonomy and naming

Caladenia saxatilis was first formally described in 2006 by David Jones, who gave it the name Arachnorchis saxatilis and published the description in Australian Orchid Research from a specimen collected on the eastern side of the Mount Remarkable National Park.[2] In 2010, Robert Bates changed the name to Caladenia saxatilis.[3][4] The specific epithet (saxatilis) is a Latin word meaning "among rocks",[5] referring to the rocky habitat where this species usually grows.[1]

Distribution and habitat

This spider orchid occurs in the Flinders Ranges, Northern Lofty, Murray and Yorke Peninsula botanical regions of South Australia where it grows among rocks in tall forest.[1][6][7]
