200 MR. DRUMMOND’S COLLECTIONS. 
Orl. (». 53).—I am quite doubtful respecting what I have 
here called 8. and y. Mr. Arnott and myself were at one 
time disposed to refer the foliage of 8. to A. saccharinum: 
but if the flowers distributed really belong to the same plant, 
it is probably referable to A. rubrum; and the var. y. we had 
proposed calling 4. Drummondii. The fruit distributed 
certainly belongs to the foliage: still, without flowering 
specimens, I have thought it safer to consider it a var. of the 
present species. The forest-trees are eminently difficult of 
investigation, except to those who have the advantage of 
studying them on their native soil. 
143. A. dasycarpum, Willd.—A. eriocarpum, Mich.—Alle-

154. V. rotundifolia, Mich.—N. Orl.—My specimens of 
this exactly agree with the description of Elliott, who, how- 
ever, thinks, that the P. vulpina of Walter, and even of 
Linnæus, may be the same. Mr. Greene has sent me 2
