MR. DRUMMOND’S COLLECTIONS, 185 
very limited, and comparatively of little interest, have been 
but partially distributed. It is otherwise with those from St. 
Louis on the Missouri, N. Orleans, including Pontchar- 
traine, (first. collection, readily distinguished by the printed 
labels and numbers,) Covington, Jacksonville, and N. Orleans, 
(second collection.) Of most of these there were many dupli- 
cates, and a large portion of them are in possession of the 
subscribers; preference, in regard to number, being given to 
those friends of Mr. Drummond who contributed most 
largely to his outfit, or who were the earliest to subscribe. 
I am indebted to Dr. Greville for assistance in determining 
the names of several plants from St. Louis, and to Mr. Arnott 
for the same service with regard to the first collection from 
New Orleans. I only regret that a similar advantage was 
not afforded me with the rest of this extensive Herbarium. 
I have, however, received most important aids in the nume- 
rous authentic specimens of plants of the Southern States, 
given me by my excellent friends, Dr. Boott, Dr. Torrey, 
Mr. Nuttall, B. D. Greene, Esq., the late Mr. Elliott, Dr. 
Wray, Dr. Darlington, Dr. Short, and Mr. Townsend, with- 
out which my catalogue would have been far more imper- 
fect than it now appears. William Wilson, Esq., has kindly 
undertaken the examination of the Mosses, which, though by 
no means so numerous as those of the Northern States, 
yet contain some highly curious species. It is intended 
to accompany the distribution of these with names. 
Besides the service I trust this catalogue may render to 
those who possess any portion of Mr. Drummond's plants, 
it may be considered useful as showing the geographical range 
of the species it embraces.

that C. lineariloba is a variety of C. Walteri, with narrower
