i ' ; 



not cork-barke.d, and in the Vienna Botanic Garden, 20 inches in 

 diameter of trunk, and 40 feet or more across its extended 

 branches. This, too, is not cork-barked. A tree capable of 

 standing drouth well. I am at a loss to know what name to give 

 this tree. English cork-barked Maple will not do for a tree 

 worthless to us if grown from English seed ; a tree not always 

 cork-barked. Let us procure seed of this pretty shrub maple — 

 seed of northern grbwth. We need direct communication with the 

 Botanic Gardens, and Nurserymen and Seedsmen of our own like 

 climates in Northern Europe. 



A. NEGUNDO FOL. VARiEGATis OR ARGENTUM. — This is a variety 

 of our Ash-leafed Maple, with white edged foliage. It is very 

 ornamental, and largely used, top-grafted in Central Europe. 

 Farther North, grown as a low shrub with slight protection, other- 

 wise not at all hardy in extreme climates. 



A. PiATANOiDES. Norway Maple. — We did not find this tree 

 grown in as large quantity in Russia as I had expected ; nor did 

 we even find specimens of it as large as our own sugar Maple. 

 We find it as a street tree, and in gardens in all the Russian towns, 

 but in limited quantity only. I noticed on the Volga, in the dry 

 regions, that the trees growing there, trees looking just like the 

 Platanoides of Western Europe, stood drouth remarkably well. 



Var. DISSECTUM. — This pretty thing we found in severe 

 climates, and in Vienna we saw a specimen 8 inches in diameter 

 of trunk, with a dense, round head, nearly 30 feet in height, show- 

 ing that it attains larger size than I had expected. 



Var. FOL. DIGITALIS we saw only at the Pomological School 

 at Proskau, in Eastern Prussia. A small tree with leaves still 

 more cut than Dissecta. 



Var. Reitenbachi a curious and a pretty tree. Leaves, dull 

 brown in summer, and in spring, red. I do not remember seeing 

 it North of Warsaw. 



Var. ScHWERDLERii. — A Maple with young shoots bright 

 red. Quite hardy at Riga says Mr. Wagner. I should not expect 

 it to prove hardy farther north.
