. It is known from only a single population in the Meehan Range, south-eastern Tasmania. It is thought to be closely related to ''O. lycopodioides'' and ''O. selaginoides''.


Description

''Ozothamnus reflexifolius'' usually grows to between high, branches slender and spreading. The leaves are closely arranged, alternate, and sessile, bright green, glabrous, long, wide, strongly reflexed and parallel to the stem in older growth. The reflexed portion of the leaf is broadly ovate to orbicular, long, wide, the strongly reflexed mature leaves differentiating ''O. reflexifolius'' from ''O. lycopodioides'' and ''O. selaginoides''.

is cream to yellowish, hemispherical, diameter, without stalks, grouped in clusters of five to eight at the ends of the branches, and overtopped by the branches arising immediately below the inflorescences. Flowering occurs from November to March and the fruits are cylindric shaped cypsela, long, small and dry with a tuft of barbed bristles at the apex. Seeds are highly fecund and germinate readily although have a short period of viability.


Conservation status

''Ozothamnus reflexifolius'' is listed as vulnerable under the Environment Protection and Biodiversity Conservation Act 1999 and the Threatened Species Protection Act 1995 (Tasmania).


Taxonomy and naming

The species was described in 2003 by Kevin E Leeson and Andrew C Rozefelds after discovery in 2000 by Richard Schahinger. ''O. reflexifolius'' is named for the reflexed appearance of the adult leaves.
