Perennial herb arising from stout woody rhizomatous rootstock; stems 1-4, robust and somewhat fleshy, unbranched, ascending or erect, 0.3-1 m long, glabrous and commonly glaucous. Leaves sessile or subsessile, (4-)7-12 x (1.3-)3-6 cm, ovate to lanceolate, acute, cordate at the base, margins smooth, glabrous, generally glaucous with a waxy bloom on both surfaces, veins prominent, sometimes reddish. Inflorescences extra-axillary with (6-)9-15 flowers in a nodding umbel; peduncles 1.5-6 cm long, mostly half to 2/3 length of subtending leaf, glabrous and generally glaucous; bracts 5-10 x 0.5-1 mm, filiform to linear, margins ciliate or not; pedicels 2-3.5 cm long, glabrous, glaucous or not. Calyx lobes 7-10 x 2-4 mm, oblong to broadly ovate, apex obtuse to acute, glabrous, green or glaucous. Corolla united at the base for 1-2 mm, greenish yellow, sometimes purplish on outer face, minutely papillate particularly towards base; lobes strongly or weakly reflexed, 9-12 x 5-8 mm, ovate, acute. Corona lobes attached c.1.5 mm above base of staminal column, similar to G. swynnertonii but measuring 4-6 x 3-6 mm, upper margin ± level with head of staminal column. Anther wings 2-2.5 x 0.5-1 mm, triangular, outer margin straight or weakly concave; anther appendages c.1 x 1 mm, broadly ovate, obtuse, indexed over apex of stigma head. Corpusculum c.0.4 x 0.15 mm, ovoid-subcylindrical, black, with translucent flanges running up sides from attachment of translator arms; translator arms c.0.5 x 0.15 mm, flattened and ± uniform in width but differentially thickened-inner margin thicker near corpusculum, outer margin thicker near pollinium; pollinia c.1.2 x 0.4 mm, oblanceolate. Follicles 5.5-10 x 1.5-3.5 cm, fusiform with occasional longitudinal wings and an acute apex or oblong-elliptic in outline and somewhat inflated with an obtuse apex, glabrous, glaucous, usually only one of the pair developing; fruiting peduncle contorted to hold follicle erect. Seeds c.6 x 5 mm, ± suborbicular with a slightly convoluted, pale and minutely pubescent margin surrounding a verrucose pubescent disc; coma c.4 cm long, ivory.
