Pelargonium betulinum (l.) l'hér. Willd.

Erect to decumbent, branched to much-branched, non-aromatic shrub or subshrub, up to 1.5 m high and 1.5 m in diameter. Stems herbaceous when young but soon becoming woody, sparsely to densely pubescent and with a few glandular hairs in between, green but becoming brownish with age. Leaves glabrescent to hirtellous and with a few scattered glandular hairs, green; lamina circular to broadly elliptic to ovate, flat, veins depressed, base shallowly cordate to cuneate, apex obtuse, margin usually rather coarsely dentate to serrate with the teeth often red-tipped, (8-)20(-10) x (5-)15(-30) mm; petiole (4-)10(-20) mm long; stipules triangular, usually acuminate, pubescent and with a few glandular hairs in between, 3-7 x 1-4 mm. Inflorescence: flowering branches with normal and smaller foliar leaves; peduncles 15-90 mm long, pubescent to villous and with glandular hairs interspersed; involucral bracts lanceolate, apiculate, indumentum as on stipules, 6-8 x 2-3 mm; pseudo-umbels with 2-6 flowers each. Pedicel 4-15 mm long, pubescent to pilose and with glandular hairs interspersed. Hypanthium 3-8 mm long, indumentum as on pedicel. Sepals lanceolate, indumentum abaxially as on pedicel, green to reddish-brown with a white margin, ca 12 x 2-4 mm. Petals pale pink to purplish, exceptionally almost white; posterior two broadly spathulate to obovate, with feather-like reddish-purple markings, reflexed at less than 90°, ±25 x 15 mm; anterior three spathulate with rather broad claws, slightly reflexed, ±22 x 7 mm. P. betulinum flowers from August to January with a peak during September to November. Odd flowers are found throughout the year.
