Convolvulus verecundus Allan

Low-growing ± pubescent perennial herb or subshrub; stock rather stout, often multicipital; branches spreading, slender, ± woody at base, up to c. 3 dm. long. All parts silky-hairy or in some forms nearly glab. Lvs alt., often several together at nodes, on slender petioles up to 2-3 cm. long. Lamina grey-green, broad-ovate to oblong or suborbicular, (5)-8-20 × (5)-8-15-(20) mm.; apex emarginate, base truncate to subcordate, sinus very shallow, margins ± sinuate to rather coarsely crenate. Peduncles very slender, 1-4 cm. long, us. 1-fld, us. with a pair of linear bracts ± 1-3 mm. long, rather distant from calyx. Sepals obovate-oblong, persistent, 3-5 mm. long, pubescent. Corolla white, c. 15 mm. long and diam. Capsule 5-6-(7) mm. diam., valves thin, glab. or very nearly so. Seeds wrinkled, ± hairy, tubercled, c. 3 mm. diam., very dark brown.

Convolvulus verecundus Allan

Low-growing perennial herb, with creeping rhizomatous stems, short ascending to spreading branches, and lianoid stems up to 20 cm; lianoid stems with a sparse to moderate covering of retrorse hairs. Leaves in rosettes and alternate on stems, 6.5–11.5 × 5.0–12.5 mm, deltoid, deltoidovate to ± broad-oblong, grey, grey-green, to silvergrey; moderately to densely hairy, rarely sparsely hairy, hairs antrorse and appressed; veins prominent and strongly translucent; margin undulate, occasionally sinuate, or with 4–6 pairs of teeth; base truncate, obtuse, occasionally oblique or slightly cordate; apex usually retuse, occasionally obtuse; petiole channelled, sparsely to moderately covered with retrorse and antrorse hairs. Pedicel 5–30(–55) mm long, 0.4–1.2 mm diam., moderately hairy. Sepals 3.9–4.1 × 3.5–3.8 mm, obovate to ovate, green; abaxial surface sparsely to moderately hairy, adaxial surface glabrous; margin fimbriate and translucent; apex subacute to obtuse. Corolla 12– 19 mm long in bud, 20–25 mm wide when open, white, rarely pink, five lobes fused their full length, lobe apex fringed with hairs; tube 5–8 mm long, palegreen; abaxial surface with mid-petaline pink bands with sparse appressed hairs on upper half. Nectary annular, 0.3–0.4 mm tall, yellow. Style 2-cleft, white; fused portion 6.0–9.0 mm long, c. 0.2 mm wide; stigmata 2.5–4.0 × c. 0.5 mm. Ovary c. 1.0 × 1.0–1.2 mm, cream. Filaments 4.0–4.6 mm long, c. 0.5 mm wide at base, tapering to c. 0.2 mm at apex, white; margin with scattered short hairs on lower half; fused to base of corolla tube. Anthers 1.7– 2.0 mm long, white. Capsule 5.8–6.2 mm long, 4.5– 7.5 mm wide, chartaceous, globose, with 2–4 seeds, lower half enclosed in persistent calyx, style base remnant persistent. Seeds* segment-shaped and broader toward apex with a rounded dorsal and two flattened lateral faces meeting at an acute ventral edge, or rounded and broadly obovate without distinct angles, almost triangular to terete in section; 2.8–3.9 × 2.4–3.0 mm; apex and base rounded; hilum concave. Testa black-brown overlaid and ornamented with grey nut-brown, dull, glabrous, moderately covered in low ridges and tubercules, sometimes forming ridges on margins.
