Ranunculus L. |
R. brachylobus Boiss. & Hoh. in Boiss., Diagn. ser. 1(8): 6 (1849). Glabrescent perennial, 3-30(-40) cm. Rhizome oblique. Stems subscapose,
1-2-flowered, glabrous or adpressed pilose above. Radical leaves with blade glabrous, thickish, trilobed, tripartite or even trisect, segments broadly cuneate, crenately lobed or incised. Sepals adpressed, often reddish. Petals 6-12 mm. Torus pilose. Achenes obovate-orbicular, inflated or somewhat compressed, 2-2.5 mm; beak uncinate, 0.75-1.0 mm. 1. Leaves divided to 1/2 or 3/4 into obtuse, crenate-dentate segments; achene apparently inflated, with an obtuse abaxial margin subsp. brachylobus 1. Leaves more deeply tripartite or even trisect, the segments more deeply incised into coarse subobtuse teeth; achene apparently ± compressed, with a sub- ' carinate abaxial margin subsp. incisilobatus subsp. incisilobatus Davis in Notes R.B.G. Edinb. 23 : 129, t. 9 (1960). Figures 4, 5, pp. 157, 173. Fl. 6-8. Rocky slopes and alpine pastures, by stream and melting snow, 1940-3650 m. Type: [Turkey B7] Tunceli: Munzur Da. above Ovacik. 2400 m, D. 31342 (holo. E! iso. K! BM!). Mountains of E. Anatolia, Cilician Taurus. B7 Tunceli: Munzur Da. above Ovacik, 2800 m, D. 31237! Erzincan: Kara Da. (Erzincan-Refahiye) 1940 m, Hub.-Mor. 13090! B9 Bitlis: d. Kotum, Karz Da. above Kamer, 2600-2700 m, D. 2459(7! Van: Çuh Gediği pass, Hoşap to Başkale, 2840 m, Hub.-Mor. 10959! C5 Içel: Dombelek Da., 2600 m, Siehe 1895: 203! C9 Hakkari: Cilo Da., 3650 m, D. 24179! N. Iraq. Ir.-Tur. element. Ripe fruits are required to confirm the apparent difference in achene shape. Specimens from Sipikor Da. near Erzincan (Sint. 1118, 3335!) are intermediate between the two subspecies. Several Caucasian taxa (R. baidarae Rupr., R. crassifolius (Rupr.) Grossh., and R. dzavakheticus Ovcz.) are very closely allied to R. brachylobus. The whole group requires a biosystematic approach similar to that carried out by Landolt (Ber. Schweiz. Bot. Ges. 64: 1954) on allied species in Central Europe. |
