ence leaves base truncate, roughish above. 
556. Celtis salicifolia Raf. Tree, branch- 
lets terete pilose with white dots, leaves oblong 
elongate narrow subacuminate sharply serrate* 
base obliqual acute trinervate,potiols and nerves 
pubescent — in Arkanzas and Louisiana, a small 
tree 20 feet high, leaves 2 to 4 inches long simi- 
lar to some Willows but quite obliqual, very 
different from all the narrow leaved kinds, 
nearer to C. occidentalis, but very different 
leaves. Is it a deviation of C . fuscata ? chief 
difference in terete pilose branches, nerves pu- 
bescent <f*c. 
557. Celtis levigata W. Loud. Leaves 
unequaly cordate obliqual acuminate nearly en- 
tire, smooth on both sides — in Louisiana, small 
tree 20 feet high. I have not seen it, it was 
described in Wildenow Enumeration, I copy 
the notice from Loudun Cyclop, of plants. It 
appears different from all the cordate leaved 
kinds by the smooth leaves, and from my mori- 
folia and patula by obliqual acuminate leaves. 
558. Celtis morifolia Raf. C. cordata of 
some botanists ? — Tree, branchlets redish hir- 
sute angular or striate, leaves ovate oblong ser- 
rate acute or acuminate, base subcordate or 
truncate, slightly obliqual, scabrose above, be- 
neath smooth pale reticulate, nerves yellow hir- 
sute, petiols pubescent, pedicels longer than pe- 
tiols — this is one of the 3 sp. blended and call- 
ed Hackberry in the Western States. This is 
a tree 26 to 40 feet high, the branches have 
neither warts nor dots. Leaves 3 to 5 inches 
long, 1 or 2 wide, becoming quite smooth be- 
neath when old, but always rough above hardly 
trinervate, but nerves regular and reticulate. 
Found in Illinois, Kentucky if I remember
