LANDSCAPE GARDENING. 
The Willow oak. ( Q. P hellos.) This remarkable species of 
oak may be recognised at once by its narrow, entire leaves, 
shaped almost like those of the willow, and about the same 
size, though thicker in texture. It is not found wild north of 
the barrens of New-Jersey, where it grows plentifully, but 
thrives well in cultivation much farther north. The stem of 
this tree is remarkably smooth in every stage of its growth. 
It is so different in appearance and character from the other 
species of this genus, that in plantations it would never be 
recognised by a person not conversant with oaks, as one of the 
family. It deserves to be introduced into landscapes for its 
singularity as an oak, and its lightness and elegance of foliage 
individually. 
The Mossy-cup oak. ( Q. olivceformis.) This is so called 
because the scales of the cups terminate in a long, moss- 
like fringe, nearly covering the acorn. It is quite a rare 
species, being only found on the upper banks of the Hudson, 
and on the Genesee river. The foliage is fine, large, and 
deeply cut, and the lower branches of the tree droop in a 
beautiful manner when it has attained some considerable 
size. Quercus macrocarpa , the Over-cup White oak, is 
another beautiful kind found in the western states, which a 
good deal resembles the Mossy-cup oak in the acorn. The 
foliage, however, is uncommonly fine, being the largest in 
size of any American species ; fifteen inches long, and eight 
broad. It is a noble tree, with fine deep green foliage ; and 
the growth of a specimen planted in our grounds has been 
remarkably vigorous. 
Scarlet oak. ( Quercus coccinea.) A native of the mid- 
dle states ; a noble tree, often eighty feet high. The leaves, 
borne on long petioles, are a bright lively green on both 
surfaces, with four deep cuts on each side, widest at the
