Description
Logania diffusa is a slender and lightly branched, spreading shrub usually growing to 60 cm, but occasionally to 2m high. The stems are erect or ascending with minute hairs between the lateral ridges. The leaves are narrowly linear, stalkless, less than 3cm long and up to 1mm wide, with short hairs on the under surface. The leaf margins are strongly curved downward.
Flowers are in clusters, arranged on short branched stalks arising from the junctions of the leaves with the stems. The flower clusters are much shorter than the adjoining leaves. Male flowers form clusters of up to 10 and female flowers are in clusters of 3-5. The petals are white and up to 2mm long and the flowers have a delicate, sweet perfume when fresh. Fruits are egg shaped capsules up to 3mm in length. (Henderson 1985; Conn 1995; Wang 1995; DEWHA 2008)
