Eriochilus dilatatus
Eriochilus dilatatus, commonly known as the white bunny orchid, is a plant in the orchid family Orchidaceae and is endemic to Western Australia. It is a common and widespread, slender ground orchid with a single leaf and up to fifteen small white and greenish flowers with reddish or brownish markings and a hairy labellum. Description. "Eriochilus dilatatus" is a terrestrial, perennial, deciduous, herb with an underground tuber. Plants in flower have a single, egg-shaped leaf long and wide and attached about half way up the flowering stem. Plants not in flower usually have a larger leaf on  a stalk tall. Up to fifteen, usually more than three white and greenish flowers long and wide are borne on a flowering stem tall. The dorsal sepal is spatula-shaped, long and wide. The lateral sepals are white or cream-coloured, long and wide. The petals are greenish with brownish-red stripes, long, about wide and more or less erect. The labellum is greenish cream, long and wide with clusters of cream-coloured to pale purple hairs, and is prominently curved downwards. Flowering occurs between March and June with some subspecies flowering more prolifically after fire. Taxonomy, naming and distribution . "Eriochilus dilatatus" was first formally described in 1840 by John Lindley and the description was published in "A Sketch of the Vegetation of the Swan River Colony". The specific epithet ("dilatatus") is a Latin word meaning "spread out", "enlarge", or "extend", referring to the broad labellum and lateral sepals. There are six subspecies: Ecology. All bunny orchids are pollinated by small native bees, attracted to nectar at the base of the labellum. Use in horticulture. "Eriochilus" species are generally easily grown in pots in a bushhouse or cool glasshouse. They need to be watered regularly when growing but kept dry  when dormant during summer.
