    Habit
    Perennial decumbent (occasionally tufted) herb; stems up to 1.3 m. long, straggling, often reddish to pink, branching, subsucculent, arising from a woody base; internodes up to 13 cm. long; vegetative parts, peduncles and pedicels glandular, ± pubescent to almost glabrous, hairs rather patent or somewhat adpressed on the leaves; glands sessile, glittering-gold; glandular hairs on the red stem parts usually filled with red pigments.

    Leaves opposite, sometimes alternate towards the stem-base; lamina narrowly ovate to ovate in outline, 1.5–5.5 cm. long, 1.5–5 cm. wide, cordate, 3-partite to 3-foliolate (sometimes much dissected, giving several subopposite pairs of pinnae plus the terminal one), with a larger middle section of the leaflet, sometimes only shallowly 3-lobed or pinnatifid to pinnatisect; segments or pinnae somewhat rhombic in outline, almost unlobed to pinnatipartite, the margin crenate, the hairs scattered and often restricted to the margins and veins; petiole 2–8(–12) cm. long; stipules narrowly to broadly ovate, 5–10 mm. long, 2–7 mm. wide, acute to apiculate at the apex, membranous.
    Inflorescences
    Inflorescence a terminal simple umbel of 2–4(–5) flowers or the flowers sometimessolitary; peduncle 5–9(–13) cm. long, leaf-opposed or in the axil of the smaller of the 2 apparently opposite leaves; pedicels 1–3 mm. long; bracts 4–8 per node, lanceolate, acute, membranous, 5–8 mm. long, 1.5–3 mm. wide.
