glandular being subject to that species of blight, indicated 

 by a blistered and monstrous growth of the leaves and 

 shoots, but not to the mildew, in any injurious degree. The 

 class without glands is generally free from the blister, but 

 liable to the curl in the leaves, and tops of the shoots, to 

 the attacks of aphides, and to the mildew : it is also more 

 hardy in its habits, and consequently better adapted to a 

 raw moist climate. 



Amongst the gland-bearing Peaches, may be reckoned 

 the red Nutmeg, the Alberge, the Admirable, and most 

 of the sorts called French Peaches, as Mignonnes, Chev- 

 reuses, Galandes, &c. Amongst the glandless, are the 

 Early Anne, the Magdalen, the Noblesse, the Montauban,. 

 the Newington, &c. The Nectarines are mostly glandu- 

 lar ; the only one which I have met without glands, being 

 the Newington * Perhaps the same law of organization, 

 which gives birth to smoothness and thickness in the leaf, 

 may have a greater tendency to form a firm substance, and 

 smooth skin in the fruit ; rather than a tender pulp and 

 downy coat, the latter being but a further developement of 

 the former qualities. 



A Nectarine has been found to grow on a Peach tree ; 

 I am inclined to conjecture, that it was on one with a 

 glandular leaf, and that if ever a Peach shall appear 

 on a Nectarine tree, it will be on one with glandless 

 leaves. 



Every attempt to reduce varieties, the sport of nature, 

 to systematic order, must be liable to imperfection ; but I 

 hope that these outlines may assist in lessening the confu- 



* Not noticed, I believe, by the French.
