Diagnostic Description

Laundon (1961, p. 63) reduced G. nyassense to subspecific rank under G. incanum, from which, however, it is amply distinct: differences in both leaf cutting and indumentum distinguish them, and their geographical separation is enormous. This is not apparent from Laundon's discussion, because he confused both G. multisectum and G. magniflorum with G. incanum.

    Morphology

    Diffuse perennial herb, stems slender, well-branched, sprawling, somewhat woody, with appressed as well as spreading hairs. Stipules deeply dissected, segments linear-acuminate. Leaves all cauline, petioles long, all but the uppermost exceeding the blades in length, with sparse fine appressed hairs, long spreading hairs few or many, blade up to ±40 mm in diam., digitately (3-)5(-7)-lobed to the base, each lobe deeply pinnatifid, the segments oblong-lanceolate, larger ones often coarsely toothed, margins ± revolute, appressed-pubescent above, finely appressed-pubescent below, with coarser hairs over the veins and frequently long spreading hairs as well, slightly discolorous. Peduncles opposite the upper leaves and much exceeding them, with appressed as well as few to many spreading hairs, 1- or 2-flowered. Pedicels seldom exceeding 30 mm long, hairy like the peduncles. Sepals 5-6 x 2-2.5 mm excluding mucro, with fine appressed pubescence, sometimes coarser spreading hairs as well. Petals 9-12 x 3-4 mm, obovate, entire or shallowly notched, white or pink. Rostrum with fine ascending hairs.
