Pelargonium radulifolium Steud.

A geophyte with exposed parts poorly developed, deciduous, unarmed, up to 300 mm tall when in flower. Exposed stems rough Geographical distribution and habitat preference due to stipular and petiolar scars, basally hard and woody, distally herbaceous and sparsely villous with glandular hairs interspersed, initially green but turning brown with age, up to 120 mm long and 2-10 mm thick. Leaves basal, erect, pinnate to 2-pinnatifid, herbaceous, glabrous to adaxially strigose or hirsute with short glandular hairs on both surfaces; lamina 2-3 times as long as wide, base of segments cuneate, apices of segments rounded, margins dentate, up to 280(-320) x 90 (-160) mm; petiole up to 130 mm long, deciduous; stipules cordiform to ovate with apices acute, 5-10 x 3-8 mm, membranous becoming scarious, sparsely ciliate, abaxially densely strigulose becoming glabrous, with scattered glandular harts. Inflorescence a stout unbranched peduncle up to 200 mm long and up to 3 mm in diameter, carrying a pseudo-umbel of 4-20 almost regular flowers. Pedicel much shorter than hypanthium: 1.0-2.5 mm long, densely strigose and with glandular hairs. Hypanthium 20-55 mm long. Sepals narrowly ovate with apices acute, abaxially densely. strigulose and with scattered glandular hairs, adaxially glabrous, margins ciliate, yellow-green with apices red and margins hyaline, 6-10 x 1-3 mm. Petals 5, almost equal, 11-18 mm long, dull yellow to flesh-coloured with maroon to purple-black markings, spathulate with apices rounded; posterior two 4.0-5.5 mm wide, reflexed at ±90° near base and slightly inflexed at apex; anterior three 3.5-5.0 mm wide, orientated similarly to posterior petals but less markedly reflexed. Fertile stamens 7 (4 long, 1 medium, 2 short and equalling staminodes), pollen golden yellow. Ovary pear-shaped, ±3.5 x 2.0 mm, densely covered in apically-directed hairs, pale green; style 1.0-1.5 mm long; stigma 5-branched, red; mericarp base 6-7 mm long, tail 35 x 10 mm long. It is a summer-flowering species, with its flowering period extending from August to April with a peak in January and February.
