 which are scarcely longer than the umbellule. I/ . H. Native 

 of Altaia or the mountains, and at Lake Baikal. Allied to B.

24 B. GRAMINIFOLIUM (Vahl. symb. 3. p. 48.) stem nearly

 Alps of Europe and the Pyrenees. Rcem. fl. eur. fasc. 7. with 

 a figure. D. C. fl. fr. 4. p. 367. Spreng. in Schultes, syst. 6. p. 

 368. B. petraeum, Vill. dauph. 2. p. 576. t. 14. Jacq. icon, 

 rar. 1. t. 56. This species differs from B. ranunculoides, in the 

 leaves being all nearly radical, in the involucels being often 7-8- 

 leaved, in the leaves of the involucrum being more elongated. 

 B. incurvum, Bell. app. 77. t. 11. is hardly a variety of this 

 species, unless that the leaves of the involucrum are more elon- 

 gated. B. caricifolium and B. petrae'um of many authors are 

 identical with this.
