Perennial creeping herb or subshrub; stems arising from stout us. multicipital stock, us. rhizomatous, much-branched, up to ± 3 dm. long; aerial parts ± densely clad in greyish ± villous hairs. Lvs on slender petioles 1-2 cm. long or more, us. clustered at tips of branchlets. Laminae of diverse shapes and sizes, several forms us. present on any particular plant. Three main groups may be recognized: (a) rather similar to those of C. verecundus but us. rather larger and with a pair of basal lobes; passing into (b) basal lobes larger, terminal lobe up to c. 3 cm. long, linear; (c) petioles linear to filiform, up to 5 cm. long; basal lobes up to 10 mm. long, linear, at right angles to linear, entire, sinuate or toothed terminal lobe up to 5 cm. long. Fls axillary, solitary, on slender to almost filiform peduncles up to 6 cm. long. Bracts paired, linear, c. 2-3 mm. long, near to or rather distant from calyx. Outer sepals > inner, broad-ovate, ± crenulate, ± 5 mm. long. Corolla white, ± 2 cm. long and diam. Seeds almost black, up to 5 mm. diam., finely tuberculate.

Perennial hairy herb with creeping branched stems arising from a stout, usually multicipital and rhizomatous stock. Petioles slender, usually 1-2.5 cm long, ± silky hairy. Lamina heterophyllous, 5-50 × 1-10 mm, ± silky hairy, of 4 main intergrading types, sometimes more than 1 on same plant: a) broad-ovate, oblong or suborbicular, usually not lobed, b) almost hastate with terminal sinuate or toothed lobe, and linear to narrow-oblong, entire or toothed, much smaller basal lobes at right angles, c) filiform to linear, with basal lobes entire or toothed, d) almost filiform to broadly linear and entire or nearly so. Fls axillary, solitary; peduncles ± filiform. Bracts paired, narrow-linear. Sepals unequal, 5-7 mm long, broad-ovate, ± appressed-hairy; apex rounded. Corolla c. 2 × 2 cm, white. Capsule c. 7 mm diam., globose. Seeds with network of short, narrow ridges.
