Description
editBillardiera laxiflora is a delicate, twining shrub or climber that typically grows to a height of 50 cm (20 in) and has reddish-brown stems. The adult leaves are more or less linear, 8–20 mm (0.31–0.79 in) long and 1–2 mm (0.039–0.079 in) wide on a short petiole. The flowers are arranged in umbels on a thin peduncle 10–12 mm (0.39–0.47 in) long, each flower on a pedicel 6–10 mm (0.24–0.39 in) long. The sepals are mauve and green, 2.0–4.5 mm (0.079–0.177 in) long and of different lengths. The petals are white, spotted or tinged with pink or mauve, 4–8 mm (0.16–0.31 in) long. Flowering occurs from February to June and the mature fruit is a spindle-shaped berry about 42 mm (1.7 in) long.[2][3]
