Type.

SOUTH AUSTRALIA, Cudnaka [Kanyaka], Mueller s.n. (holotype MEL; isotypes MEL, P!).

Description.

Perennial herb with trailing stems to 1 m, vegetative parts covered in long, whitish appressed velvety hairs, densely so on young growth. Leaves dimorphic: leaves of non-flowering shoots long-petiolate, 1-2 × 0.6-1.5 cm, ovate-deltoid, rounded, margin serrate, base truncate (very rarely slightly auriculate) and shortly cuneate onto the petiole, petiole 1-2 cm; leaves of flowering shoots 1-1.5(-2.5) × 0.5-1.4 cm, ovate-deltoid in outline but deeply toothed and incised towards the base; petioles 0.2-0.8 cm. Flowers solitary, pedunculate, axillary; peduncles 0.3-0.8 (-1.2)cm, becoming recurved in fruit; bracteoles linear c. 1 mm; pedicels 1-3 mm; outer sepals 4 × 3.5 mm, elliptic, apiculate, the point recurved, sericeous; inner sepals similar but with fewer hairs; corolla 5-6 mm long, white or pink, lobed with somewhat triangular lobes, midpetaline bands sericeous; ovary glabrous, style glabrous, divided 2-2.5 mm above base; stigmas c. 1.5 mm. Capsule glabrous; seeds slightly winged and with low irregular sinuate ridges. [ Johnson 2001: 15-19, f. 5-6, map 4]

Distribution.

Australia: Southern South Australia and adjacent parts of Victoria and New South Wales (Alcock 652, Kuchel 1470, Chinnock 2915, Hill et al. 5426). Johnson (2001) cites Copley 571 but this looks like an error for Convolvulus eyreanus as the peduncles are 1.5-2 cm long and mostly bear two flowers while the leaves are not so strongly sericeous.

Notes.

This species shares with Convolvulus eyreanus a dense indumentum of longish appressed hairs. Fruiting specimens can be recognised by the short recurved peduncles bearing single flowers, small capsules (4-4.5 mm in diameter) and small seeds (<3 mm long).
