Taxonomy

The first description was given in an 1878 monograph by George Bentham, published in the Flora of Australia series.[1]

The diversity of the genus Lepidosperma has been the subject of frequent revision, and a variety of this species is recognised, Lepidosperma leptostachyum var. asperatum Kük.[2] The name has been applied to populations later recognised as a new species, Lepidosperma apricola R.L. Barrett, in 2013.[3]

Description

Lepidosperma leptostachyum is herbaceous or grass-like in form, growing as clumps around 600 millimetres across. The height is an equivalent size or as low as 100 mm, the plant may be up to 1 metre in height. The brownish inflorescence appears from April to June.[1]

Distribution and habitat

The species is found in the Southwest Australia region, in a variety of soil types. They occur on slopes, on black and grey sands, lateric and peaty soils, or clay, and on gravel.[1]

The conservation status of L. leptostachyum is noted at FloraBase as not threatened.[1]
