Diagnostic Description

We have not traced an isotype of G. baurianum, the holotype of which was destroyed in the Berlin fire. But we have re-collected the plant on Baziya Mountain, and its identity is confirmed by Knuth's description.

    Morphology

    Perennial herb, tap-root eventually woody and carrot-like, surrounded by woody fusiform root-tubers, stems one or few from the crown, up to ±600 mm long, decumbent or prostrate, distantly leafy, clad in long and short spreading hairs. Stipules deeply dissected, segments linear-lanceolate. Radical leaves crowded on the crown, though sometimes few, petioles mostly 30-170 mm long, clad in long and short spreading hairs; blade mostly 20-55 mm diam., orbicular in outline, shallowly 5-7-lobed (less than halfway to the base), these lobes hemispherical in outline with a few coarse teeth, glabrous to thinly pilose above with coarse spreading hairs, coarse spreading hairs on veins below, these rarely wanting, thinly to thickly pubescent with short fine hairs between the veins; cauline leaves similar, but petioles rapidly decreasing in length upwards, uppermost leaves reduced and subsessile. Peduncles opposite the upper leaves and terminal, forming a small cyme, 10-55 mm long, usually 2-flowered, clad in long and short spreading hairs. Pedicels mostly 12-30 mm long, hairy as the peduncles. Sepals 6-9 x 2.5-3.75 mm, clad in long spreading hairs. Petals 13-18 x 6.5-10 mm, obovate in outline, entire or shallowly notched, mostly deep bright pink, but ranging from pale pink to light purple. Rostrum with short fine spreading pubescence, some coarse hairs as well, very rarely some gland-tipped.
