Young specimens, bearing only leaves and quite young flower-buds, taken by me 

 on the salt-lake of Tagarski osero, south of Minusinsk, at the beginning of July. In the 

 Urjankai country I have found the species past flowering and nearly withered on the 

 steppes on the Ulu-kem at the end of August. The specimens gathered are distinguished 

 by their rather large and broad leaves, which are sessile and nearly clasping the stem. 

 The margin of the leaves entire, or only slightly and irregularly indented, the upper as 

 well as the under side of the leaves and the stem rather densely puberulent. 



Distribution: The species is distributed over southern and central Europe, North 

 Africa, and temperate portions of Asia. The western parts of this area (Europe, North 

 Africa and south-western Asia) are taken up by subspecies eulatifoUum, while, on the 

 other hand, the eastern parts (from Persia, Afghanistan, Tibet, and eastwards through 

 southern Siberia, Mongolia, and China) are taken up by subspecies sibiricum. In bouild- 

 ary districts both forms occur growing together.

On saliferous soil, on the Abakan Steppe, near Ust Kamuishto. Flowering and 

 with young fruits in the second half of June. The specimens gathered are characteristic 

 in having very narrow leaves, from 3 to 5 mm. broad, and the length to ten times the 

 breadth, the margin rather deeply and sharply dentate, moreover, in having the stems 

 generally unbranched, or only very slightly branched, frequently sparingly pubescent. 



Distribution: The geographical range of this species is confined to south-western 

 Siberia and adjoining regions of Dzungaria, Turkestan, and Mongolia. It was heretofore 

 not observed farther to the east than the government of Tomsk.
