 plant than A. yibrotanum, and equally hardy. 



Cornus sibirica is Cornus alba sibirica Arb. Brit. 



^'sculus ohioensis Michx. had no fruit ; but we believe it to be the true 

 species rather than the plant in the Hort. Soc. Garden, from the close 

 resemblance of its foliage to that shown in Michaux's figure, and also 

 because Michaux himself assured us that it was correctly named.

 pointed lobes which induces us to refer it to ^. creticura; leaves. not 

 velvety beneath. 



A. neapolitanum, a native of the South of Italy and Hungary, &c., is A. ob- 

 tusatum Arb. Brit, Leaves velvety beneath. 



A. hybridum Bosc, a vigorous-growing plant, apparently between A. obtu- 

 satum and A. Pseudo-Platanus. Leaves very slightly velvety beneath. 



A. O'palus, A. opulifolium, A. rotundifolium, are all varieties of J. obtusatum. 

 We have no doubt of this, having been convinced of it after examining 

 the plants under the care of M. Camuset, and having heard his ex- 

 perience on the subject of these acers. In some of these varieties the 

 leaves are scarcely at all velvety beneath.
