NEW SPECIES OF ERIOGONUM. 395 
Cryptogamia are included in the search. In collecting flowering-plants, 
one can pass over the ground with considerable rapidity; but in look- 
ing for Mosses, etc., unless every erack and crevice be carefully scruti- 
nized, the rarer species are always certain of being overlooked. Thus 
Cdipodium Griffithianum was plentiful on the easternmost rocks of the 
Barries, but I saw it nowhere else in fruit, except a single small patch 
in the cliffs above Loch Callater. Bryum Zierii was plentiful in Glen 
Dole, but very scarce everywhere else. Polytrichum hercynicum was 
plentiful on the Barries and on the northern slope of Craig Wharl, but 
very scarce in Glen Dole and elsewhere. Some of the more common 
plants were also very fine in certain localities : thus, on the eastern 
stream on Craig Maid, Luzula spicata was remarkably luxuriant; in 
ascending from Canness, Sibbaldia was seen very fine ; also Gnaphalium 
supinum, the stems five inches in length. Rubus Chamemorus was no- 
where so fine as on the summit of Craig Rennet and on the southern 
slope of Lochnagar. i

This is one of the results of the Oregon and Californian Mission 
sent out by an association from Edinburgh, for botanically exploring 
* In reference to some remarks made upon this little work on some plants of the 
Oregon country, in a late number of our Journal, it is only fair to state, what we now 
learn, that it was never intended as a publication, but as a catalogue that might be 
useful to those interested in Mr. Jeffrey's mission.—E».
