 Ihe lalli'i- lias ix'i'n (lescribcd afliT al- 

 pine specimens, it bears rather the cha- 

 racter of an early summer type: vour 

 specimens no. 1140 (from islets in the 

 river Abakan) were so far more ly])i- 

 cal." According to Wettstkin's de- 

 scription, there is no other esenlial dif- 

 ference between /:. Rcgelii and E. 

 .laeschkei than the latter bearing larger 

 flowers (the corolla 8 — 10 mm. along 

 the back; in E. Regelii 5—6 mm.). The 

 specimens collected by me agree best 

 with^the description of E. Joesclikci. bv 

 the size of the corolla being ± 8 mm., 

 moreover, by the stem being glandular, 

 and the bracts having the teeth mucro- 

 nulate. It would perhaps be as right to 

 consider E. Regelii. with its wider di- 

 stribution (from the Caucasus, Persia, 

 the Himalayas, Tibet and Turkestan — 

 according to Wettstein), as the main 

 species, and the specimens with larger 

 flowers as E. Regelii var.'Jaeschkei. I lie 

 species at hand is evidently rather near- 

 ly allied to the European E. brevipiUi. 

 and E. stricta. 



In grass-field on the islets in the 

 river Abakan, above Uibat. and about 

 Kushabar. In full flower at the end of 

 June and the beginning of July. 



Distribufion: E. Regelii Wett- 

 stein occurs in the Caucasus. Persia, 

 the Himalayas. Tibet and Turkestan, 

 while the tj'pical E. Jaeschkei Wett- 

 stein is previously known only from 

 the Himalayas.
