broad, equalling or fioqiionllig exceeding liic principal ones. The disc-flowcr.s arc yellow, 

 about twice the length of the involucre; the pappus is while, of about the .same length as 

 the (lisc-floweis. or somewhat shorter, but always con.siderai)ly longer than the involucre. 

 The rays occui- to the nniiil)er of 4—8, of a deep yellow; length of the ligule itself l.j— 18 

 mm. riic aclicnes are glabrous. The leaves resemble those in Ihc lyijica! form, perhaps 

 somewhat narrower, completely glabrous or nearly so, only underneath, and especially 

 along the nerves, .sometimes .slightly and sparingly pubescent. The shape of the leaves 

 is, for the rest, considerably varying in the different specimens, narrower or broader, 

 sometimes very finely denticulate, sometimes more coarsely toothed at llic margin. The 

 lowei- leaves are more or less distinctly ]ieli()led. with winged pcliolcs, the ii|)pir ones 

 sessile, and mostly narrower than the lower ones. The stem is glabrale and slightly 

 striate. 



This varietv has been coilecli'd by me in several places in liic .\myl valley, al)oul I'sl 

 Algiac. and at Ust Kamsara. in moist, moss-grown places in llic sul)ali)ine woods. It, 

 therefore, seemed to be widely dislribuled in the Sayansk district, ll may. likewise, be of 

 a greater systematic value. In full flower, and with parlly ri|)e fruits in Die second half 

 of July. Besides this variety, I have collected, on islets in the river .Vbakan, a form with 

 the under sides of the leaves densely puberulent. Of the latter, however. I have only a 

 single specimen, with young flower-buds, and therefore I dare not identify it with certainly 

 w ilh any of the forms already known. I only purpose hereby to draw attention to this one. 



Distribution: The species is distributed in middle and soullurn Europe, Caucasia, 

 Siberia, northwards to about 69 K.° north lat., ea.stwards to the Sea of Okhotsk, Turke- 

 stan, the Thian-Shan, northern Mongolia, Manchooria. northern Corea. Cliina, Sakhalin. 

 Japan.

The specimens collected are characteristic in having the basal and lower leaves 

 generally narrowly elliptic, 3—4 cm. long, and 1..3— 2 cm. broad, rarely more orljicular or 

 neariv cordiform, and rather distinctly detached from the petiole, which is of about 

 the same length as the blade, or somewhat shorter. The leaves are entire, or slightly ser- 

 rate at the margin. The stems are comparatively long. 30—40 cm. high, the stem-leaves 

 comparatively few, small, and appressed to the stem. The heads are rather small, 

 4—12, on an average 6—8 in each plant, on peduncles 1—2.5 cm. long, and of a pale, 

 yellow colour. The whole plant is tattered tomentose and woolly-canescent, especially 

 so the stem and the under sides of the leaves. In a richer material this widely distributed 

 .species proves to vary considerably, occurring in a rather great number of distinct local 

 types. Under these circum.stances it al.so seemed difficult to make a nice distinction
