[1] Its species name 'rhomboidea' is traced from Latin rhombus, which translates to ‘a four-sided geometrical figure with all sides and opposite angles being equal’, pertaining to its diamond-shaped leaves.
[5] It is a vigorous, evergreen vine that scrambles or becomes a liana, reaching 3 to 6 m in height (6–20 feet), though it can also grow to small tree or shrub.
[5][6][2] The dark green, rhombic leaves are trifoliate that comprise three asymmetrical leaflets with short stalks which are coriaceous and satiny with pale russet hairs below and with an irregularly toothed margin.
[5] Flowers are greenish yellow, inconspicuous and small, in divided heads in the leaf axils, which appear in spring to midsummer.
[5] It is used as a garden plant, where it prefers cool, sheltered areas in summer (though winter warmth is necessary as it is frost tender).
The plant is seldom affected by pests or diseases, in addition to it being tough and enduring some negligence and living in poor conditions.
Its stem extract and the standards chloramphenicol and tetracycline all signaled an inhibition zone diameter against Salmonella sp.
