Pelargonium multiradiatum J.C.Wendl.

Geophyte with annual or ephemeral aerial growth, plant up to 500 mm tall when in flower. Exposed branches poorly branched, up to 600 mm long and 2-4 mm in diameter, smooth, succulent, densely hirsute and green initially but becoming woody, glabrous, and brown with age. Leaves 2-to 3-pinnatifidly divided into linear segments, segments up to 3 mm wide and often decurrent along rachis and rachillae so that latter are winged and at least basal segments branching off rachis at a right angle, membranous, abaxially sparsely strigose with scattered glandular hairs interspersed, adaxially practically glabrous, dull green; lamina sagittiform in outline, almost as wide as long, apices of segments obtuse to acute, margins of segments involute, up to 450 x 450 mm; petiole 200-350 mm long; stipules deltoid with apices acute, 8-10 x 6-8 mm, membranous turning scarious, indumentum mostly abaxial, stipules not caducous. Inflorescence an unbranched peduncle, 100-350 mm long and up to 2.5 mm in diameter, carrying an 8-15(-30)-flowered pseudo-umbel. Flowers almost regular, 15-20 mm in diameter. Pedicel 3(-30) mm long but usually much shorter than hypanthium, very densely strigose with glandular hairs interspersed. Hypanthium 25-35 mm long. Sepals narrowly ovate-deltoid, abaxially strigose, yellow-green or occasionally streaked with red and with margins hyaline, 6-9 x 1-2 mm. Petals 5, Pale mustard-yellow with dark maroon markings, obovate-spathulate with apices rounded and bases attenuate, reflexed near bases at ±50° and again somewhat incurving near apices; posterior two 7-12 x 4-5 mm; anterior three 7-10 x 3-1 mm. Fertile stamens 5, almost usual in total length, pollen pale yellow, staminodes much shorter. Ovary pear-shaped, 3.0 x 1.0-1.5 mm, densely covered with apically-directed hairs, pale green; style 2-3 mm long; stigma 5-branched, maroon; mericarp base 6-7 mm long, tail 30-35 mm. Flowering specimens have been collected from September to the following March, but most plants seem to flower during the summer months, from December to February. More than most other species in this subsection it tends to be evergreen.
