Lectotype of Pimpinella saxifraga L. subsp. rupestris Weide, 1962: National Museum in Prague, Czech Republic, PR162205. All specimens (isolectotypes) come from the same collection by G. Hirte (August 14, 1891) and were sent as duplicates to various herbaria (Geneva, Jena, Pruhonice). Description. Plants (5-)10-35 cm tall. Rosette leaves with +/- long petioles, 2-pinnate with 3-6(-8) pairs of sessile leaflets; leaflets rounded to ovate, evenly dentate or serrate. Stems cylindrical, sometimes slightly striate, rarely branched in the upper part, leafless or with 1-3 cauline leaves. Lower cauline leaves 1-pinnate, dentate with obtuse teeth, light green; middle cauline leaves 2-pinnate, sessile with short sheaths; leaflets of upper cauline leaves reduced, linear or lanceolate. Umbels small, with 7-14 rays of uneven length; rays smooth or +/- ciliate; involucres and involucels usually absent. Petals whitish, yellowish, sporadically pink, up to 0.7-1.0 mm long, cordate, incurved at tips. Fruits 1.0-2.0(-2.5) x 0.5-1.5(-2.0) mm, ovoid, slightly compressed, smooth with ribs distinct only at maturity (Fig. 2 ). The most important differences in the morphological structure between the nominative taxa of Pimpinella saxifraga subsp. saxifraga and the discussed P. saxifraga subsp. rupestris are given in Table 1 .
