Description
Seed Colour: Variable - brown/yellow
Seed Length: 2 - 4mmSeed Sculpture: Castellated, Tuberculate
Seed Shape: RoundA scrambling annual with four-angled stems up to 60 cm long that have small backward-pointing coarse hairs or prickles along the edges. The leaves are in rings of six to eight around the stems. The leaves are mostly 10-50 mm long and 1-5 mm wide, broadest above the middle and tapering to a blunt tip with a short central point. The upper surfaces of the leaves are smooth, but the margins and sometimes the lower surface have scattered tiny prickles. The flowers are inconspicuous, in loose groups of one to three arising from the upper stem nodes. The four triangular petals are white, about 1 mm long. The fruits develop soon after the flower opens and consist of a pair of joined, spherical nutlets, each 2-3 mm in diameter and with roughened surfaces (James & Allen 1992; Jeanes 1999).
