prises Wettstein's E. Regelii, which is more widely distributed in Asia, but all of your 

 specimens bear flowers of the larger type, whereby corresponding to E. Jaeschkei. As 

 the latter has been described after al- 

 pine specimens, it bears rather the cha- 

 racter of an early summer type; your 

 specimens no. 1140 (from islets in the 

 river Abakan) were so far more typi- 

 cal." According to Wettstein s de- 

 scription, there is no other esential dif- 

 ference between E. Regelii and E. 

 Jaeschkei 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. Jaeschkei, by 

 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. The 

 species at hand is evidently rather near- 

 ly allied to the European E. brevipila, 

 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. 



Distribution: E. Regelii Wett- 

 stein occurs in the Caucasus, Persia, 

 the Himalayas, Tibet and Turkestan, 

 while the typical E. Jaeschkei Wett- 

 stein is previously known only from 

 the Himalayas.
