Bromus mermis, Leys., and purgans, L., are both kept distinct from ciliatus, L., by 
Grisebach. I am indebted to Munro for their identification, together with that oipictus, 
mini, which is undoubtedly ciliatus, L. Asa Gray refers purgans to ciliatus. Durand 
mentions this plant as a native of Greenland, lat. 65°, under the name of B. Kalmii ?

Since the printing of the foregoing paper, I have received, through the kindness of 
Dr. Asa Gray, particulars of the discovery of Oalluna vulgaris near Tewksbury, Massa- 
chusetts, by Mr. Jackson Dawson, occurring rather abundantly over about half an acre 
of boggy ground, amongst various strictly American plants. This tends to confirm the 
statement of De la Pvlaie, that Callwict, is an inhabitant of Newfoundland.
