Convolvulus longipedicellatus Sa'ad , Meded. Bot. Mus.Herb. Rijks Univ. Utrecht 281: 233. 1967. ( Sa'ad 1967: 233). Figure 4, t. 17-23. Type. TURKEY, Merzivan, Manisadjan s.n. (holotype W!). Description. Presumably trailing herb of unknown length; stems and leaves pubescent. Leaves similar to those of Convolvulus betonicifolius , petiolate, c. 2.5 x 2 cm, ovate, obtuse and mucronate, entire, shallowly sagittate with short auricles. Flowers 1-2, pedunculate, axillary; peduncles c. 2.5 cm; bracteoles c. 5 x 0.5 mm, linear, attenuate; pedicels equalling bracts; sepals 6 x 3 mm, oblong-oblanceolate, obtuse and retuse, mucronulate, pubescent, inner sepals glabrous, membranous; corolla 2.5 cm long, colour unknown, midpetaline bands pubescent, unlobed; filaments glandular below; ovary glabrous, style 8 mm long, glabrous, stigmas 5 mm. Capsule and seeds unknown. Distribution. Turkey. Only known from the type collection. Notes. This species is not conspecific with Convolvulus arvensis as stated in the Flora of Turkey ( Parris 1978 ) but differs in the pubescent leaves and the pubescent, 6 mm long, herbaceous sepals which lack a membranous border. Instead it is clearly related to the very variable Convolvulus betonicifolius , as stated by Sa'ad , but appears to be distinct as we cannot match it with any specimens of Convolvulus betonicifolius . It differs in the shorter, obtuse and minutely retuse sepals 5-6 mm long, which lack a distinctive apical portion. The ovary is also glabrous.
