may be reciprocally grafted on the white beam tree. When plants arc to be 

 raised from seed, the seeds should be sown as soon as the fruit is ripe ; other- 

 wise, if kept till spring, and then sown, they will not come up till the spring 

 following. When it is" inconvenient to sow them immediately that they ai-e 

 g-athereci, they may be mixed with soil, and treated like haws (see Pyrus aucu- 

 paria) ; and, if sown in the March following, they will come up the same 

 .season. The varieties maybe ])ropag;ned by cuttings, or by layering; but 

 they root, by both modes, with great difficulty. Layers require to be made of 

 the young wood, and to remain attached to the stool for two years.

 Description, Sfc. These trees bear so 

 close a resemblance to P. y/Via, as to leave 

 no doubt in our minds that they are only 

 varieties and subvarieties of that species. 

 They are found in a wild state in France, 

 Germany, and Sweden ; and perhaps also 

 in the Highlands of Scotland, where, ac- 

 cording to Sir W. J. Hooker, P. JVia 

 varies in having the leaves more or less 

 cut at the margin. They are all well de- 

 serving of culture.

 brown. Habit of P. A'na. (Don's Mill., ii. p. 647.) A tree from 20 ft. 

 to 30 ft. high, a native of Nepal and Kamaon, introduced in 1820. This 

 tree is remarkable for the rapidity of its growth, its long broad leaves, and 

 their woolly whiteness ; and also for being one of the very latest trees, 

 whether foreign or indigenous, in coming into leaf; being later than either 

 the mulberry or ash. The leaves are conspicuous, on their first expansion.
