Leptocarpus coangustatus is a species of plant in the Restionaceae (rush) family, endemic to Western Australia.[1]
It was first described by Christian Gottfried Daniel Nees von Esenbeck in 1846, from plants collected by J.A.L. Preiss (in the Darling Ranges) and James Drummond (on the Swan River).[2] In 1998 Barbara Briggs and Lawrie Johnson transferred the species to the genus, Meeboldina, to give the species name, Meeboldina coangustata.[3] However in 2014, the genus Leptocarpus was expanded to include Meeboldina and by 2021 the later name was no longer accepted.
