This species is nearly allied to the European S. humilis L. It has, however, always 

 one-headed stems, bearing only a single (rarely 2), generally vei-y short and narrow, 

 frequently nearly completely reduced, linear stem-leaf, the seat of which is much varying. 

 The height of the stems varies considei-ably, being generally about twice the length of the 

 basal leaves, 18 — 25 cm. high; but I have also in my collections fully developed specimens, 

 with very short stems, equalhng or even shorter than the basal leaves. The plants vary 

 from being nearly glabrous to more or less densely tomentose. The basal leaves are nar- 

 row, generally 4—5 mm., rarely to 7 mm. broad, 10 — 20 cm. long, flat, with a long and 

 fine point, 1- or 3, rarely 5-nerved. The achenes are glabrous, and furnished with rather 

 deep longitudinal ribs, transversally inigose. I have found this species to be pretty com- 

 mon in dry meadows on the river Abakan and in the Altaian, in subalpine meadows 

 near the tree limit. 



Distribution: Siberia, from the Ural to Kamtchatka and the Amoor Province, north- 

 ern China, Sakhalin.

Scattered in somewhat diy meadows on islets in tlie river Abakan, and between 

 Minusinsk and Kushabar, where I have collected it in full flower in the second half of 

 June. The stems are simple, or 2- to 3-branched, the branches generally starting from 

 about the middle of the stem, or only slightly above. The leaves are comparatively nar- 

 row, 3 — 4 cm. broad, and 4 — 5 times as long, rather distinctly acuminate at the top, 

 sparsely and sharply serrulate at the margin. The species is, besides, rather frequently 

 to be met with in the Urjankai countr}', in diy meadows, thickets, etc., where I have 

 observed it at Ust Algiac, in several places on the Upper Sisti-kem, at Ust Sisti-kem, Ust 

 Kamsara, and Ust Tara-kem. 



Distribution: Europe, except the arctic and southern regions, Caucasia, south-west- 

 ern Asia, southern Siberia, northwards to about GO" north lat., eastwards roughly to Lake 

 Baikal.
