Diplolaena drummondii is an endemic Australian flowering plant in the family Rutaceae. It is only found in Western Australia. It is a small, spreading shrub with oblong to elliptic papery, thin leaves, and yellow, orange or reddish flowers which bloom between July and November.

Description

Diplolaena drummondii is a small, spreading shrub to 1 m (3 ft 3 in) high with papery, elliptic to oblong-elliptic leaves 20–50 mm (0.79–1.97 in) long, margins flat, wedge shaped at the base, rounded at the apex on a petiole 5–15 mm (0.20–0.59 in) long. The leaf upper surface is covered sparsely with short, soft hairs, the underside sparsely to moderately covered with star-shaped hairs. The flowerheads about 15 mm (0.59 in) in diameter, the outer green to reddish brown bracts are egg-shaped to narrowly triangular, about 8 mm (0.31 in) long, covered in star-shaped, soft, short hairs. The inner bracts are about 12 mm (0.47 in) long, narrowly oblong, covered in soft, short, star-shaped hairs that taper gradually to a point. The pale red flower petals about 9 mm (0.35 in) long and covered in smooth, short, star-shaped hairs and taper to a point. The red or yellow stamens are about 25 mm (0.98 in) long, and covered with star-shaped, soft, weak hairs toward the base. The flower petals about 9 mm (0.35 in) long, light red with star-shaped, soft, smooth hairs. Flowering occurs from July to November.[2][3]

Taxonomy

Diplolaena drummondii was first formally described in 1863 by George Bentham who gave it the name Diplolaena microcephala var. drummondii in Flora Australiensis.[4][5] In 1921 Carl Hansen Ostenfeld raised the variety to species status as Diplolaena drummondii and the change was published in Contributions to West Australian Botany, part III : Additions and notes to the flora of extra-tropical W. Australia. Biologiske meddelelser, Kongelige Danske Videnskabernes Selskab.[6]

Distribution and habitat

This species grows in woodland near Mundaring and Collie in the Darling Range.[2]
