Marianthus dryandra is a species of flowering plant in the family Pittosporaceae and is endemic to a restricted area in the southwest of Western Australia. It is an erect, straggling shrub with densely hairy new shoots, stem-clasping, egg-shaped leaves and cream-coloured flowers with maroon spots, arranged on short side shoots.
Description
Marianthus dryandra is an erect, scrambling shrub that typically grows to a height of up to 40 cm (16 in) and has densely hairy new shoots. Its leaves are egg-shaped with the narrower end towards the base, 12–15 mm (0.47–0.59 in) long, about 7 mm (0.28 in) wide and stem-clasping. The flowers are borne singly on short side shoots on a peduncle less than 10 mm (0.39 in) long. The sepals are linear, greenish-purple and hairy, about 3.5 mm (0.14 in) long. The five petals are 6–10 mm (0.24–0.39 in) long and cream-coloured with maroon spots along the veins. Flowering has been observed in October.[2][3]
Taxonomy
Marianthus dryandra was first formally described in 2004 by Lindy Cayzer and Michael Crisp in Australian Systematic Botany from specimens collected in the Dryandra State Forest.[4] The specific epithet (dryandra) refers to the type location, the only known habitat of this species.[3]
Distribution and habitat
This species of marianthus is only known from the type collection where it grows in woodland.[3][2]
Conservation status
Marianthus dryandra is listed as "Priority Two" by the Western Australian Government Department of Biodiversity, Conservation and Attractions,[2] meaning that it is poorly known and from only one or a few locations.[5]
