scientific name

status

 

168. Convolvulus tschimganicus Popov & Vved., Byull. Sredne-Aziatsk. Gosud. Univ. 15 (Suppl.): 31. 1927. (Popov and Vvedensky (1927: 31).

Type.

Western Tian Shan, Popov in Fl. As. Med. Fasc. 12, 288 (holotype TAK; isotypes E!, G, K!, LE!, P!, W!).

Distinguishing features.

As rightly noted by Popov and Vvedensky (1927: 31) Convolvulus tschimganicus is intermediate morphologically between Convolvulus pilosellifolius and Convolvulus dorycnium subsp. subhirsutus differing from the former by the distant flowers borne on nearly straight branches and the sepals 5-6 mm long, oblong-obovate, mucronate, not distinctly bicoloured and the larger corolla 1.6-1.8 cm long. It is distinguished from the latter by its more slender, less rigid habit, spreading indumentum and the stems unbranched except near the apex so creating a less divaricate inflorescence.

Distribution.

Endemic to Uzbekistan (Korovin s.n. [11/7/1928], Khokhryekov s.n. [8/8/1960]). Apparently rare.

Notes.

The status of this species is unclear and it may be of hybrid origin.
