BOTANICAL CLASSIFICATION. 215 



produces, eighteen are natives of the Russian dominions and the 

 countries adjacent. Most of these are very similar to the Euro- 

 pean portion of the genus, and five are common both to Europe 

 and Asia. Of the remainder, one, which is, perhaps, a distinct 

 genus, has been discovered in Persia, fifteen in China, and two 

 of the latter, with four others, in the north of India, &c.i 



We shall not here describe all the species mentioned by Lindley 

 and Loudon ; but only those possessing some distinct character- 

 istics. A large part of the species described by these authors 

 cannot be found in any collection in this country ; and in fact, 

 very few possess any interest except to the Botanist, for whose 

 benefit chiefly is this classification. 



I. FEROCES. Lindl. Mon., p. 3. 



Derivation. From ferox, fierce : in reference to the branches being thickly beset with 

 prickles. 



Sect. Char. Branches clothed with permanent tomentnm. Fruit 



naked. The plants contained in this section are a truly natural group ; 



they are low shrubs, losing their leaves early in autumn, and are then 



remarkable for their hoary branches, bristles, and numerous prickles. 



Their fruit is perfectly smooth, which separates them from the next 



section, in which the fruit is downy. Sepals usually toothed. {Don's 



Mill., 2, p. 565.)
