Based on Convolvulus canescens Phil. Type. Based on Convolvulus dissectus Cav. Description. Thinly to densely pubescent herb from a thick rootstock, sometimes sericeous on young parts, but more or less glabrescent; stems trailing (rarely twining), up to 2.5 m long. Leaves petiolate, 2-8 x 2-6 cm, very variable in form, usually linear or oblong with prominent elongate bifurcate basal auricles, but occasionally ovate-deltoid to suborbicular with rounded auricles, apex usually acute, margin entire or undulate, base cordate to truncate; petioles 0.5-3.5 cm. Flowers 1-2 (-3), axillary, pedunculate; peduncles 2-4 (-6.5) cm; bracteoles 2-4 mm, lanceolate; pedicels 5-10 mm; outer sepals 7-9 x 5-7 mm, elliptic, obtuse, mucronate; corolla 1.5-2.5 cm long, pink, very shallowly lobed with slightly fimbriate margins, midpetaline bands dark, pilose, terminating in a pilose mucro; ovary glabrous; style divided 6-10 mm above base, stigmas 1.5-3.5 mm, cylindrical to linear, unusually variable. Capsule glabrous; seeds rugose. [ O'Donell 1957 : 161-166 (Figure 6); Hoffmann 1998 : 207] Distribution. Endemic to central Chile from Antofagasta south to Santiago ( Worth & Morrison 16236, Bridges s.n., Gardner & Knees 5652, 8467, DCI 1791). 0-1800 m. Notes. This polymorphic species is usually easily distinguished from all other South American species by the leaves with bifurcate auricles combined with pink corollas usually around 2-2.5 cm long. However, some specimens from Coquimbo ( Simon 312 (MICH, RSA), Wagenknecht 18445 (F)) have small, suborbicular sericeous leaves and merit further study. The type location is given as Chillan , but this is almost certainly an error as the plant has never subsequently been collected so far south ( O'Donell 1957 : 161).
