54 MR. DRUMMOND’S COLLECTIONS. 
may serve as a memento of my having been at Philadelphia. I 3 
have met with several Mosses which I did not find in my - 
former journeyings in the more northern latitudes, in sufficient — 
quantity for publication: such as Leucodon, sp.? Gymnostomum - 
pyriforme, Diphyscium foliosum, Buxbaumia aphylla, several — 
Phasca, Polytrichum tenue, Tortula, sp., Didymodon pallidus, — 
Grimmia, allied to pulvinata, and another resembling Glypho- a 
mitrion Daviesii, Pterogonium, two species, and a Hypnum, n. spa 
&c. Ihave visited several of the museums here, and observed a. — 
great many interesting objects which I hope to find myself. — 
Amongst them I have examined the collection of Mosses of the — 
celebrated Muhlenberg.* The specimens are miserable, butstill _ 
sufficient to enable me to assure myself that there are many I — 
have not yet met with. I have been to see the garden that once — 
was Bartram’s, and found that it was still kept up as a nursery * 
by Colonel Case; and that it retained some very fine specimens — 
of trees. The season, however, is said to be unusually back- — 
ward, but I find it quite warm enough for my pursuits. The - 
early Peas are just coming into meen and the Potatoes ap- — 
pearing above ground. The only vegetables of this season’s — 
growth in the market are Asparagus and Radishes. In the — 
woods are a good many species of Viola, and in one day's walk | 
I have observed, in flower, V. pedata, V. palmata, V. cucul- — 
lata, V. debilis, V. ovaio, V. lanceolata, and one or two others — 
with which 1 am not so well acquainted. I shall proceed ims 
: mediately to Baltimore and Washington, where I find it will | 
be necessary to go, in order to procure letters from the Go- — 
vernment to the military posts on the Missouri, &c.; thence - 
of some very rare and some new Mosses, an excellent set of the spring — 
plants of Pennsylvania, especially of the Vaccinium tribe, Gonolobus ob- 
liquus, Br. &c. and the little known Floerkia, of which genus an account — 
. is given at page 1. of the present vol., from the pen of Professor Lindley.
