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. 1 



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 tomentum. 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. (Doris 

 Mill, 2, p. 565.)

 Fruit globose, scarlet. A shrub, a native of Caucasus, growing to the height of 3 ft. or

 or 4 ft., and flowering in June and July. 



II. BRACTEATJ3. 







Sect. Char. Branches and fruit clothed with permanent tomentum. 

 This section is readily distinguished from the last by the woolliness of 

 the fruit. Leaves dense, usually shining, and prickles placed under the 

 stipules in pairs. Sepals simple, or nearly so. (Don's Mill., 2, p. 565.)
