Small-leaved Fire Vine; Fire Vine; Vine, Small-leaved Fire
Usually grows as a tree-top vine but also flowers and fruits as a shrub. Vine stem diameters to 5 cm recorded. Vascular rays visible to the naked eye in stem transverse sections, equally obvious in the bark.
Leaf blades scabrous (sandpapery) often on both the upper and lower surfaces due to the presence of short hairs which tend to disappear as each leaf ages. Leaf blades about 6-20 x 4-7.5 cm, petioles about 1-3.5 cm long, grooved on the upper surface. Venation distinctive, with the main lateral veins extending from the midrib all the way to the margin of the leaf blade. Small stellate hairs usually visible with a lens on both the upper and lower surfaces of the younger leaves. Young leaf bearing twigs usually scabrous and will sometimes inflict 'rope burns' on exposed skin on the legs and arms of the poor unfortunates lost in the primaeval forest.
Inflorescences up to 20 cm or longer. Flowers sweetly perfumed, about 6-10 mm diam. Sepals +/- orbicular, about 3-5 mm diam. Petals caducous, about 8-9 mm long. Stamens numerous, about 5 mm long. Anthers obtriangular in outline, about 1 x 1 mm with the anther locules in each corner of the anther. Staminal filaments about 4 mm long. Stamens about 4-5 mm long, anther locules quite separate at the apex. Carpels 2-4 (usually 3) hairy, each carpel about 1.5-2 mm long. Styles about 3-3.5 mm long. Ovules about 10 per carpel.
Fruiting carpels clothed in pale +/- prostrate hairs. Carpels ovoid, about 5-8 x 3-5 mm with a 1-2 mm beak. Seeds one. Aril much larger than the seed, aril margin fimbriate with numerous long slender lobes. Endosperm granular. Embryo very small, no more than 1 mm long, cotyledons not exceeding the width of the radicle.
