Adenanthos glabrescens is a species of small shrub endemic to the Ravensthorpe area in southwest Western Australia. First published in 1978, there are two subspecies.
Description
Adenanthos glabrescens grows as an erect shrub up to 70 cm in height. It has pinkish red or cream flowers, with a
The species is quite similar to A. dobsonii, but the leaves of A. dobsonii retain an indumentum of soft hairs both long and short, whereas those of A. glabrescens have an indumentum of short hairs only, which is soon lost.[1]
Taxonomy
There are botanical collections attributable to this species dating back at least to 1924, but it was not until 1978 that
Nelson followed
Two subspecies were recognised:
- A. glabrescens subsp. glabrescens has long narrow leaves and a lignotuber. It occurs in deep siliceous sand in the vicinity of, and south of, Lake King.[1]
- A. glabrescens subsp. exasperatus has ovate leaves much like those of A. dobsonii, and lacks a lignotuber. It occurs in gravelly sand on rocky slopes, and is known only from two populations, one in the Fitzgerald River National Park, the other east of Ravensthorpe.[1]
