  • Ranunculus pathanorum Rech. f.
  • Ranunculus pseudo-laetus Tamura

    Tall perennial, 30-70 cm high, with a creeping rootstock producing numerous fibrous roots and flowering stems. Stems up to 5 mm thick, usually much branched, with appressed or spreading hairs, especially near the base often glabrescent later. Basal leaves with long petioles (12-15 cm), densely patent-hairy, blade c. 10 cm wide, rounded-reniform, ternate, with broadly obovate segments, free to near the base, segments often deeply 2 or 3-lobed beyond the middle, lobes obovate, coarsely irregularly incised or dentate, teeth triangular, sharply pointed, appressed hairy on both surfaces. Stem leaves sessile, lower ones shortly petiolate, decreasing in size upwards, divided in the same way as the lower ones, upper most bract-l ike leaves with narrower linear or linear-lanceolate to lanceolate segments. Flowers 17-25 mm in diameter, yellow. Sepals 5-7 mm, lanceolate to ovate-lanceolate with a wide membranous margin, acute or subobtuse, densely whitish-hairy. Petals 8-12 mm, roundish obovate, sometimes tapering into an indistinct claw. Achenes 2-2.5 (2.5) mm in diameter, numerous, suborbicular, slightly compressed with a distinct margin,inserted in an oblong glabrous receptacle. Style c. 0.3-0.5 mm, triangular, flattened, ± straight.

    Fl. Per.: June-July.

    Probably this is the most common species of Ranunculus in Pakistan, easily recognised by its size, leaf shape and distinct venation of leaves. The taxa Ranunculus laetus var, kashmiricus R.A. Qureshi & M.N. Chaudhri and Ranunculus laetus subsp. chitralicus are undoubtedly morphological variants of the widespread Ranunculus laetus. According to the authors (op.cit.) the former differs in the larger leaves and ultimate segment lobes that are cuneate-oblong, and the latter in h aving a vertical (not horizontal) rootstock and stem and leaves that are subglabrous or less hairy. In my opinion, these characters overlap and are not constant and reliable. Found from 1200-2740 m.
