In the specimens collected the whole plant is densely puberulent, the upper as 

 well as the under side of the leaves, the stem, pedicels and fruits as well. The 

 leaves are deeply indented, with acute lobes. On the Abakan Steppe, at Ust Kamuishto, 

 on dry, sloping cliffs, and in dry, sandy places, nearly past flowering and with ripe 

 fruits in the second half of June. 



Distribution: Mountain regions of middle Europe, from the Pyrenees through the 

 Alps, the Apennines to the Caucasus, Asia Minor, south-western Asia to the Himalayas, 

 Siberia (except the Amoor Province), northern Mongolia.

An exceedingly variable species — entered by Lecoyer, 1. c. (1885) p. 293 with no 

 less than 210 synonyms — of very common occurrence on the islets in the river Abakan, 

 especially in the luxuriant natural meadows, where constituting one of the most charac- 

 teristic plants. A very luxuriant form, of a deep green colour, is to be found in the said 

 localities, with stems considerably exceeding 1 m. in height, attaining from 6 to 7 mm. 

 in diameter at the root. The stems are of a green or yellowish colour, round, hollow, 

 mostly deeply striate, more or less geniculate at the nodes, generally with leafless sheaths 

 at the base, in the upper part, from about the middle, rather much branched, with 

 spreading branches. The stem, like the whole plant as well, is completely glabrous. The 

 leaves are triternate, the lower ones long-petioled, the upper ones sessile, all of them 

 generally with brownish, membranous stipule like appendages at the base. The lower 

 leaves are to 25 cm. long, and 18 cm. broad, the outline being triangular, or ovate. The 

 shape and incision of the leaflets are very variable, their length up to towards 2 cm., of 

 a rather light colour on the under side, with prominent nerves, the margin involute, 

 and the summit 3 or 5-lobed, sometimes doubly lobed. The leaflets have generally 

 short petioles, or are sometimes sessile as well. The panicle is rather large, with spread- 

 ing branches, and rather few flowers, but the floweriness is, on the whole, somewhat 

 varying. During the flowering the flowers are more or less drooping, on pedicels 

 from 0,5 cm. to 1,5 cm. long. The sepals are narrowly ovate to lanceolate, 3 or 5-
