Description

Caladenia subtilis is a terrestrial, perennial, deciduous, herb with an underground tuber and a single leaf, long and wide. A single greenish to cream-coloured flower wide is borne on a stalk tall. The sepals have dark red, club-like glandular tips long. The dorsal sepal is erect, long and about wide. The lateral sepals are long, about wide and spread apart from each other, curving downwards. The petals are long, about wide and arranged like the lateral sepals. The labellum is long, wide and whitish with a dark red, downcurved tip.

Taxonomy and naming

Caladenia subtilis was first described in 1999 by David Jones from a specimen collected in a state forest near Nowendoc and the description was published in The Orchadian. The specific epithet is a Latin word meaning "fine", "delicate" or "nice".
