islands of Penobscot Bay, Maine, and lies about 12 miles south of 
Mt. Desert Island. It has a length of one and a half mile, with a

upon it, during a two hours visit on 26th of August last:

Coptis trifolia^ Salisb. C. arvense, Scop. 
Capsella Bursa-pastoris, Moench, Vaccinmm Pennsylvanicum^ Lam.

The species printed in Roman seem to be recent introductions on 
the cleared portions of the island, perhaps by the agency of sheep 
and birds. The remaining species belong to the flora of the neigh-
