The specimens collected arc especially disLinguished by having the leaves 5- lo 8- 

 pinnate, with very approximate pinnae. The upper pinnae are largest, and decrease in 

 size down the rachis. The incisions of the pinnae nearly reach the vein; the segments 

 are linear, very fine and narrow, 0,5 — 1 mm. broad, with distinctly Fccurved margins, and 

 subobtuse summits. The leaves are densely white-pubescent on both sides. Of common 

 occurrence on the dry Devonian sandstone cliffs on the Abakan Steppe. In full flower in 

 the second half of June. 



Distribution: Eastern Russia (Perm, Orenburg), Siberia to Trans Baikal, central 

 Asia, the Caucasus, and Armenia?

Scattered on the steppes between Minusinsk and Ust Abakansk, where I have taken 

 it in full flower at the beginning of June. 



Besides the typical species, agreeing perfectly with Bunge's authentic specimens, I 

 have collected, on the steppes on the Yenisei, near Ust Abakansk, some specimens diffe- 

 ring in various respects, and which I enter as: 



var. glandulosa nov. var. [Tab. VII, Fig. 3.] 



Caudex crassiis, validus, lignosus residuis 

 foliorum vetustorum obtectus. Caules numerosi, 

 tenues, graciles, subadscendentes, multiflori, pilis 

 longis, albis, pateniibus puree vestiti. Folia radicalia 

 breviter petiolata, ambitu oblonge obovata, 3-^fjuga. 

 Foliola oblonge obovata fissa, laciniae aequilaiae, 

 0,5-2 mm. - saepissime 1-1,5 mm. - latae,apicesub- 

 obtusae et marginibus distincte revolutis, siibtus 

 albo-tomentosae, glandulisflavis, minutis, numerosis 

 praeditae, supra virides, pilis sparsis vestitae. Stipii- 

 lae suffuscae, membranaceae, lanceolatae, apice acu- 

 minatae in lacinias longas, fdiformes fissae. Flores 

 numerosi, 12-H mm. diametro. Sepala dense io- 

 mentosa et glandulosa, externa quasi spatulata 

 vel clavata, apice late rotundata, interna fere 

 triangularia, acuminata, externis longiora. Pelala 

 ftava obovata velcordata, antice leviter emarginata. Stamina et carpella ut in specie tgpica. 



In the shape of the leaves this variety differs distinctly from the typical P. soon- 

 gorica, especially so in the narrower, linear, rather approximate segments of the leaflets, 

 moreover, in having the under sides of the leaves densely white-felted and with distinct-
