Geographical Distributions

Rourea minor is distributed from tropical Africa, Madagas­car, to Sri Lanka, continental Southeast Asia, throughout Malaysia (except the Lesser Sunda Is­lands and east of Bali), to Northern Australia, New Caledonia, the New Hebrides, Fiji and Samoa. [2]

R. minor occurs in habitats ranging from secondary forests and bamboo forests to primary rainforests, and swamps to coastal rocks, with a preference for more open locations, from sea level up to 1800 m altitude. [2]

Botanical Description

R. minor is a member of the family Connaraceae. It is a large liana that can reach up to 26 m long and its stem is up to 15 cm in diametre. It is rarely a small tree or shrub with smooth twigs. [2]

The leaves are unifoliolate to 9-­jugate. The leaflets are suborbicular or ovate to lance-shaped, with one terminal that is sometimes obovate, measure 1-25 cm x 0.5-10 cm, acute to cordate at base, oblique to equilateral, short and broad to caudate at apex, acuminate and with blunt acu­men. [2]

The inflorescence is in the upper leaf axils or pseudo-terminal consisting of 1-5 axes. The central axis is up to 20 cm long, loosely paniculate to sub­racemose and many-flowered. The sepal is 2-3 mm long, minutely hairy to hairless while the petal is 4-7.5 mm long. [2]

The follicle is oblique-ellipsoid to oblique-ovoid, straight to curved, measures1-3 cm x 0.3-1 cm and dehiscing with a ventral lengthwise slit or circumscissile at the base. [2]
