The species of Daphne are notoriously difficult of dis- 

 crimination by available characters of habit, flowers or 

 foliage, of which fact the 8. European and Oriental 

 D. oleoides, Schreb., which has fifteen recorded names, is a 

 conspicuous instance. In the case of the plant here 

 figured, I am in doubt whether to call it D. caucasica, or 

 I), altaica, Pall. According to Meissner's characters of 

 these species they differ only in the former having leaves 

 lanceolate, 2-5 flowers in a head and a glabrous ovary, and 

 the latter leaves lanceolate or oblong, 2-20 flowers in a 

 head, and an ovary puberulous at the top. Thus the 

 character of the leaves and number of flowers are of no 

 avail, and in the plant here figured the ovary agrees with 

 neither, having merely a few hairs on its surface. 



Referring to Herbarium specimens, I find no appreciable 

 difference between the Caucasian and Altaic ones, and it is 



December 1st, 1894.
