C. simplicicaulis Boiss. & Huet in Boiss., Diagn. ser. 2(3): 67 (1856). Syn: C. adjarica Albow in Bull. Herb. Boiss. sèr. 1, 2:639 (1894)!   Perennial with branched rootstock, forming tufts with numerous sterile shoots and erect simple stems (very rarely with 1-2 branches), 5-35 cm, with leaves mainly in lower quarter. Leaves green and sparsely tomentose above, densely adpressed grey-tomentose below, very variable in outline, basal leaves mostly pinnatisect to lyrate with 1-4 pairs of elliptic to circular lateral segments and slightly to conspicuously larger elliptic, lanceolate or circular terminal segments, 7-15 mm broad, leaves of sterile shoots sometimes entire, ovate-cordate. Cauline leaves pinnatipartite with 1-2 pairs of linear-lanceolate lateral segments or (upper ones) simple and bract-like. Involucre (12-)14-19 x(7-)9-14 mm. Appendages small to moderately large, 2.5-5 mm broad, circular, scarcely decurrent, brown with hyaline slightly toothed margin (teeth up to 0.5 mm). Flowers rose-coloured, marginal strongly radiant. Achenes c. 4-5 mm; pappus 5-8(-10) mm. Fl. 5-6. Rock crevices and ledges, scree, 400-2600 m.   Type: [Turkey A8 Erzurum] in Armenia prope Ispir, vi 1853, Huet du Pavilion (iso. BM! G! GOET! K!).   N.E. Anatolia. A7 Giresun: 18 km from Yavuzkemal to Tamdere, 950 m, Hub.-Mor. 15866! Trabzon: Maçka, 750 m, Balls 304a! A8 Erzurum: above Ispir, 1840 m, Buttler 14273! Çoruh: Artvin, Radde 377 (type of C. adjarica)! Artvin, 400 m, Stainton 8260! A9 Çoruh: 10 km E. of Ardanuç, 1500 m, Watson et al, 3097!   Transcaucasia. Euxine element. Although the number of available collections is not large they show a remarkable variability in the form of the leaves, the size of the appendages and the distinctness of the teeth. Local populations seem to have a distinct habit, but it remains very doubtful if any of them requires formal taxonomic recognition. The same may be true for most of the new 'species' described in this group from Transcaucasia, perhaps also for C. bella Trautv. recorded from 'in confinis Turciae distr. Achalzich' by Trautvetter.
