Cryptandra intermedia explained

Cryptandra intermedia is a flowering plant in the family Rhamnaceae and is endemic to the southwest of Western Australia. It is a small shrub, usually with spiny branchlets, elliptic to linear leaves and spike-like clusters of white, tube-shaped flowers.

Description

Cryptandra intermedia is a shrub that typically grows to a height of and usually has spiny branchlets. The leaves are elliptic to linear in outline, long and wide, on a petiole long with stipules long and a small sharp point on the tip. The upper surface of the leaves is glabrous, the edges turned down or rolled under, often concealing the densely hairy lower surface. The flowers are borne in head-like clusters of 2 to 10, surrounded by about 8 broadly egg-shaped to oblong bracts. The floral tube is long, the sepals long and glabrous, and the petals are about long.[1]

Taxonomy and naming

This cryptandra was first formally described in 1995 by Barbara Lynette Rye who gave it the name Cryptandra arbutiflora var. intermedia in the journal Nuytsia from specimens collected near the Jurien Bay turnoff from the Brand Highway in 1992.[2] [3] In 2007, Rye raised the variety to species status as Cryptandra intermedia in a later edition of Nuytsia.[4] The specific epithet (intermedia ) means "coming between", referring to the floral morphology of this species in relation to others in the genus.

Distribution

Cryptandra intermedia grows in rocky and undulating places, on slopes and hilltops, in winter-wet sites and along creeks, mostly between Cockleshell Gully, Mount Peron, Gingin and Moora in the Avon Wheatbelt, Esperance Plains, Geraldton Sandplains, Jarrah Forest and Swan Coastal Plain bioregions of south-western Western Australia.

Conservation status

Cryptandra intermedia is listed as "not threatened" by the Western Australian Government Department of Biodiversity, Conservation and Attractions.
