Description

Banksia lepidorhiza is a prostrate shrub that typically grows to a width of Template:Cvt with underground stems and a lignotuber. It has dull green, pinnatipartite leaves with between fifteen and twenty-five linear, sharply pointed lobes on each side. The flowers are arranged in heads of between twenty-five and thirty with narrow lance-shaped, involucral bracts Template:Cvt long at the base of the head. The flowers have a deep pink perianth Template:Cvt long and a cream-coloured and dull yellow pistil Template:Cvt long. Flowering occurs from October to November and the follicles are broadly egg-shaped, Template:Cvt long and glabrous.[1][2][3]

Taxonomy and naming

This species was first formally described in 1996 by Alex George who gave it the name Dryandra lepidorhiza and published the description in the journal Nuytsia from a specimen he collected west of Woodanilling in 1986.[3][4] The specific epithet (lepidorhiza) is from the ancient Greek words Script error: No such module "Lang". (Script error: No such module "Lang".), meaning 'scale', and Script error: No such module "Lang". (Script error: No such module "Lang".), meaning 'root', referring to the underground stems that are covered with scale-like bracts.[3]

In 2007 Austin Mast and Kevin Thiele transferred all dryandras to the genus Banksia and renamed this species Banksia lepidorhiza.[5][6]

Distribution and habitat

Banksia lepidorhiza is only known from the type location where it grows in low kwongan in the Avon Wheatbelt biogeographic region.[1][3]

Conservation status

This banksia is classified as "Priority One" by the Government of Western Australia Department of Parks and Wildlife,[1] meaning that it is known from only one or a few locations which are potentially at risk.[7]
