Stems herbaceous when young but soon becoming woody, glabrous to villous but always with numerous glandular hairs, green but becoming brownish with age. Leaves glabrescent but with numerous glandular hairs, green to dark green; lamina cordiform in outline; 3-palmatilobate to pinnatisect, basal segments often irregularly incised, base cordate, apices of segments acute, margins finely to coarsely dentate-serrate and with short sharp-pointed hairs, (15-)50(-120) x (12-)55(-130) mm; petiole (5-)30(-80) mm long, indumentum as on stems; stipules narrowly triangular to triangular, cuspidate, indumentum as on stems, ±7 x 5 mm. Inflorescence: flowering branches with normal and smaller foliar leaves; peduncles 15-80 mm long, distinctly articulated at distal and proximal ends in infructescences, glabrous to sparsely villous but always with numerous glandular hairs; involucral bracts ovate, cuspidate, villous and densely interspersed with glandular hairs, 5-8 x 2-4 mm; pseudo-umbels with 1-8 flowers each. Pedicel 1 mm long. Hypanthium 3-10 mm long, villous and densely interspersed with glandular hairs. Sepals narrowly lanceolate to broadly spathulate, apiculate, indumentum abaxially as on hypanthium, green to reddish-brown with a white margin, ±12 x 3-6 mm. Petals pale pink to dark pink; posterior two spathulate, apices obtuse, with dark pink-purplish markings, reflexed at less than 90°, 12-25 x 5-8 mm; anterior three spathulate with long narrow claws, slightly reflexed, 12-25 x 4-8 mm.
