Eriochilus dilatatus subsp. multiflorus explained

Eriochilus dilatatus subsp. multiflorus, commonly known as the common bunny orchid, is a plant in the orchid family Orchidaceae and is endemic to Western Australia. It has a single short, smooth, flattened, egg-shaped leaf and up to twenty dull green, red and white flowers which are often closely packed. It grows in forest and woodland between Perth and Albany.

Description

Eriochilus dilatatus subsp. multiflorus is a terrestrial, perennial, deciduous, herb with an underground tuber and a single smooth, flattened, egg-shaped leaf, NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. The leaf is held above ground on a stalk up to 100sigfig=1NaNsigfig=1 long and is often not fully developed at flowering time. When plants are not flowering, the leaf is much larger. Up to twenty flowers NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide are borne on a flowering stem NaNsigfig=1NaNsigfig=1 tall. The flowers are greenish with reddish markings, except for the lateral sepals which are white and are often crowded along the flowering stem. The dorsal sepal is egg-shaped to spatula-shaped, NaNsigfig=1NaNsigfig=1 long and about 3sigfig=1NaNsigfig=1 wide. The lateral sepals are NaNsigfig=1NaNsigfig=1 long and NaNsigfig=1NaNsigfig=1 wide. The petals are NaNsigfig=1NaNsigfig=1 long, about 1sigfig=1NaNsigfig=1 wide and turned towards the dorsal sepal. The labellum is greenish to cream-coloured with red spots, NaNsigfig=1NaNsigfig=1 long, NaNsigfig=1NaNsigfig=1 wide with three lobes and scattered clusters of red and white bristles. Flowering occurs from March to June and is enhanced by fire the previous summer.[1] [2] [3] [4]

Taxonomy and naming

The common bunny orchid was first formally described in 1840 by John Lindley who gave it the name Eriochilus multiflorus and published the description in A Sketch of the Vegetation of the Swan River Colony.[5] In 2006, Stephen Hopper and Andrew Brown reduced it to subspecies status.[6] The subspecies epithet (multiflorus) is a Latin word meaning "many-flowered".[7] }

Distribution and habitat

The common bunny orchid is widespread and common in woodland and forest between Perth and Albany.

Conservation

Eriochilus dilatatus subsp. multiflorus is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.
