Convolvulus spicatus Peter ex Hallier f., Bot. Jahrb. Syst. 18: 99. 1893 [ "1894" ]. (Hallier 1893: 99). Figure 24, t. 7-13 Type . EGYPT, Sinai, Wadi Feiran, March s.n. (lectotype GOET, designated by Sa'ad 1967 : 169). Description. Villous perennial to 40 cm. Leaves sessile, 1.3-7 x 0.4-1.2 cm, oblong to oblanceolate, acute, margin entire, attenuate at the base, softly white-villous. Flowers in dense axillary heads; peduncles 1.5-3.5 cm, exceeding bracts; bracteoles 6-15 x 1-2 mm, linear-lanceolate, acuminate, densely villous; outer sepals 7-10 x 2-3 mm, lanceolate, acuminate, inner sepals narrower, 1-2 mm wide; corolla 2-2.5 cm, unlobed, midpetaline bands pubescent, terminating in a tooth; ovary and style glabrous; style divided c. 3 mm above base, the stigmas 5 mm, longer than the united part of the style. [ Sa'ad 1967 : 169; Boulos 2000 : 247] Distribution. Egypt: Sinai ( Bove 503, Danin s.n. [28/5/1962]), Jordan: Wadi Sirhan ( Hunting Survey 117a). Apparently very rare. Notes. Differs from the two previous species in the pedunculate heads but superficially identical to Convolvulus cephalopodus subsp. bushiricus , from which it is distinguished by the glabrous ovary. Very similar to Convolvulus schimperi differing in the ascending habit and in the leaves which are not undulate. The lectotype is a meagre specimen and all the other cited specimens represent more complete material.
