Caladenia dundasiae

Caladenia dundasiae has a single erect, hairy leaf, long and wide. One or two flowers wide are borne on a stalk high. The flowers are red or sometimes pink or cream-coloured. The dorsal sepal is erect, long and wide at the base. The lateral sepals are a similar size to the dorsal sepal but are widely separated and held stiffly at a downward angle. The petals are similar to the lateral sepals but slightly shorter and narrower. The labellum is long and wide and red with a white or cream-coloured base and short, forward-facing teeth on its sides. There are two rows of red and white calli along the centre of the labellum. Flowering occurs from July to August. This species is similar to C. erythrochila but has more stiffly-held and shorter sepals and petals. ==Taxonomy and naming==
