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.
