Parsonsia longipetiolata J.B.Williams
Vine stem diameters to 5 cm recorded. Exudate milky, quite obvious even when not copious. Vessels arranged in wavy more or less radial lines. Inner blaze layers markedly speckled and granular. Dead bark often showing layers in cross section. Sinuous or curved sections of bark can be seen in the wood when viewed with a lens. These bark segments sometimes produce a milky exudate when freshly cut.
Leaves, twigs and petioles produce a milky exudate. Leaf blades about 5.5-10.5 x 2.5-6 cm, petioles about 2-4 cm long. Small finger-shaped glands about 0.5 mm long and resembling stipules are present on a line across the twig between the petiole bases. When shed, these glands leave a scar resembling a stipular scar on the twig. Glands may also be visible in the leaf axils. Colleters absent.
Calyx lobes about 1.5 mm long. Corolla lobes about 6 x 1.2 mm. Corolla tube densely clothed with downward pointing white hairs on the inner surface towards the base. Anthers about 4 mm long, fused together to form a cone around the style. Disk consists of 5 green, finger-like glands around the base of the ovary.
