R. dissectus Bieb., Fl. Taur.-Cauc. 2: 25 (1808).   Perennial, 5-20 cm, glabrous, pilose or villosulous. Rhizome oblique; collar strongly fibrous. Stem 1-3-flowered, erect or sometimes procumbent. Radical leaves trisect to subpinnatisect, central segment sessile or long-stalked; lamina round to broadly ovate, segments deeply dissected into toothed or entire laciniae of variable form. Upper leaves 1-3-sect into linear laciniae. Sepals spreading. Petals 8-18 mm. Achenes obovate-semicircular, 2-3 mm, compressed, glabrous, without a conspicuous nerve parallel to the margin; beak uncinate or circinate, 0.5-0.75 mm.   A very polymorphic, dwarf, few-flowered species, allied to R. caucasicus and R. fenzlii, but differing (among other characters) in having achenes without a prominent nerve parallel to the adaxial margin. Subsp. dissectus is confined to mountain Crimea, but 5 other subspecies can be recognised in Anatolia where the complex has its centre in the North-East.* 1. Flowers large, usually 3-3.5 cm across. (Leaves suborbicular in outline; laciniae oblong-linear (sometimes cuneate-oblong) with short lateral teeth, densely adpressed-pilose, rarely glabrescent. Stems erect, sturdy, 10-25 cm, often 1.5 mm thick) subsp. napellifolius 1. Flowers smaller, less than 3 cm across    2. Laciniae cuneate-oblong and mostly tridentate at apex; leaves usually sub-orbicular in outline, villosulous like the stems. (Flowers 15-20 (often 20) mm across. Stems sturdy) subsp. huetii    2. Laciniae lanceolate, oblong-lanceolate or linear-lanceolate, entire or with one or more slender lateral teeth; leaves ovate or suborbicular in outline, glabrous or subpilose      3. Laciniae linear or linear-lanceolate, 1-1.5 mm broad, subentire, glabrous, very numerous; lamina ovate-orbicular, 2-3 cm long; sepals glabrescent. (Flowers 15-20 cm across. Plant very slender) subsp. rigidulus      3. Laciniae lanceolate or oblong-lanceolate, mostly 1.5-2 mm broad, often with one or more lateral teeth, glabrous or subpilose; sepals hairy         4. Lamina 3-5 cm long, ovate in outline; laciniae 3-15 mm long; stem sturdy (1.5 mm thick), procumbent-ascending and 2-3-flowered; rootstock thick (often 1 cm broad); flowers usually 20-27 cm across . subsp. glabrescens         4. Lamina 1-3 cm long, suborbicular or ovate in outline, laciniae or teeth 3-8 mm long; stem slender (scarcely 1 mm thick), erect, 1-2-flowered; rootstock slender, usually less than 5 mm broad; flowers 15-20(-25) mm across subsp. sibthorpii subsp. napellifolius (DC.)
