Description

Pointed Trefoil is a climbing herb with hairy stems. The leaves are divided into three leaflets which are broadly egg-shaped or diamond-shaped, 5-15 cm long and 5-7.5 cm wide, with a pointed tip. Both leaf surfaces are more or less softly hairy, with the upper surface often becoming hairless. The leaf stem is 3-10 cm long. The flower spikes are 5-15 cm long, and have 20-50 yellowish-green flowers which are 10-12mm long. These occur in spring-summer. The fruit is a 20-30 mm long oblong pod, and is densely covered with short, velvety, greenish-yellow hairs. There are two rounded, blue-black seeds in each fruit that are around 5mm long.

Distribution

It occurs in Queensland and NSW and is known from only nine locations north of Lismore, six of which occur within National Parks and Nature Reserves, and three in State Forests. Populations are generally small, comprising few individuals scattered over a wide area.
