Darwinia biflora

Status: Vulnerable on the EPBC Act list

Darwinia biflora is an erect, sometimes spreading, shrub around 20-80 cm tall. The leaves are successive pairs at right angles to each other. The leaves are 6-10 mm long, without hairs or scales, laterally compressed and frequently pressed closely against the branch. The fruit is a nut 1.2-1.7 mm in diameter. The flowers, when open, are white turning to pink in the upper parts with a green floral tube. The flower shape is tubular with the stamens and perianth parts inserted in the rim. This floral tube is 5-8 mm long, becoming constricted towards the apex, and has broad rounded longitudinal ridges. The flowers are usually in pairs with a stalk < 1 mm long. Bracts are shaped like the leaves or are triangular, 1-8 mm in length and membrane-like. The bracteoles are purple-red and fall off after the flower has opened. The style is 10-14 mm long, straight or slightly curved and yellow-green, occasionally becoming red, with a ring of hairs.
