About Loeseneriella barbata (F.Muell.) C.T.White
Loeseneriella barbata is a woody vine with a stem diameter that reaches up to 4 cm (1.6 in). Its tendrils often form knot-like coils around supporting structures. The species has stiff leaves arranged in opposite pairs; the leaves can be elliptic, ovate, or lanceolate, and grow up to 12 cm (4.7 in) long and 6 cm (2.4 in) wide. Flowers grow in branched cymes, are roughly 10 mm (0.39 in) wide, and have 5 or 6 yellow petals. The fruit is a capsule about 5 cm (2.0 in) long and 3 cm (1.2 in) wide, holding multiple winged seeds that are approximately 3 cm (1.2 in) long. This plant, commonly called knot vine, has two widely separated populations in eastern Australia. One population is located in eastern Queensland and northeastern New South Wales: the northern population extends from the tip of Cape York Peninsula south to around Ayr. The southern population starts at Rockhampton, roughly 530 km (330 mi) south of Ayr, and continues into the far northern corner of New South Wales as far south as Grafton.
