soniewhal appressed hairs. The under sides of the leaves are, however, frequently spar- 

 ingly pubescent along the midveins. The stem is of a deep reddish brown, and Uke 

 the pedicels, measuring 6—7 mm. in length, completely glabrous. 



Collected with young fruits about the middle of July, in several places on the Upper 

 Amyl, near Ust Algiac, and near Ust Sisti-kem in the middle of August. My material 

 agrees rather perfectly with var. glabrescens Rupr. var. « in Turczan. 1. c. p. 305, 

 Herder, 1. c. 



Distribution: Northern and middle Europe, Caucasia, Turkestan, Siberia, in the

This species is rather common in the coniferous forests of southern Siberia and the 

 Urjankai country, where found be me in the valleys of the rivers Amyl, Sisti-kem, and 

 Bei-kem. In his monography, WrrxROCK bases the classification of the numerous forms 

 of this species upon the colours of the corolla, but as a trustworthy inquiry into the ori- 

 ginal colours cannot be founded on dried material, I have not dared to identify my spe- 

 cimens with any of those mentioned there. Taken with flowers and fruits in July and 

 August. 



Distribution: Northern and middle Europe, Caucasia, the subalpine regions of 

 Siberia, eastwards to Kamtchatka, northern Mongolia, Manchooria, northern China, 

 Corea, Sakhalin, Japan, North America.
