of the larger kinds. The Dog Rose, the Tree Rose, and 

 other common species, grow 10 or 12 feet high, and may be 

 set in lawns, or yards where the ground is not to be broken. 

 The dwarf kinds, besides being more beautiful, require cul- 

 ture at the root. The Dutch method is to bud several varie- 

 ties of the dwarf, on the larger stalks, and thus to produce a 

 tree, composed of various, and differently colored species of 

 living Roses. It is obvious that the beauty of such a com- 

 pound tree will depend much on the taste of the culturer, in 

 arranging his varieties. The dwarf species are said to be pre- 

 served in this manner longer than by the usual mode of culture. 



The nursery men call their roses by various names, often 

 of their own invention ; and being like others, aware how 

 much great names and high sounding titles influence the 

 world, it is curious to observe how constantly they attempt to 

 employ this circumstance to enhance the sale and price of 

 their goods. Thus we have Roses named Royal crimson, 

 Purple crimson, Grand Sultan, Henry IV., Duchess of Or- 

 leans, Josephine, Napoleon, King of France, Glory of the 

 World, &c. The species of the Rose are chiefly deciduous 

 shrubs. There are a few, however, which are evergreens, 

 and several which trail upon the ground. In general, they 

 grow from a few inches to four or six feet high. A few spe- 

 cies assume the height of trees. Lady Banks' Rose, grows 

 twenty feet high, and the Persian Rose tree is said to be 

 thirty feet in height. 



It is a remarkable fact that no species of the Rose has 

 been found native in the southern hemisphere. 

 CLASS XIIL POLYANDRIA. Stamens many, inserted 

 on the receptacle. Orders 7. 



The name of this class is derived from Fi s- N 



the Greek, polys, many, and aner, a sta- 

 men, and means many stamens. The 

 stamens in this class, instead of being 

 inserted into the calyx, as in Icosandria, 

 grow on the receptacle, or end of the 

 stem, and under the germen. It is a cu- 

 rious circumstance, that plants with their
