ON OAKESIA, 445 
in the New Jersey plant. In 1840, a still more northern 
station for the shrub was added by Mr. Nuttall, (Herb. 
nostr.) who gathered it in the flowering state, on the banks of 
the Kennebeck River in Maine. A specimen from the 
Lambertian Herbarium, in my possession, of the female plant 
in an advanced state, which is labelled on the back of the 
paper, * Newfoundland, Cormack,” in the handwriting of Mr. 
Lambert, affords the only other habitat, with which we are 
as yet acquainted.* It seems likely that the range of our 
plant, though extending so far south as the warm sands of 
New Jersey, will yet prove on the whole quite northern. I 
have now only to add the complete diagnosis of Dr. Klotzsch, 
which affords no room (to me, at least.) for improvement. 
But the name given by him to the new plant, being previ- 
ously assigned to a different genus, I venture to propose for 
it another, in honour of my kind friend William Oakes, Bag: o 
of Ipswich, Masstts. I cannot but think it is with pecu 
propriety that our plant wil commemorate a name in- 
separably connected with the New England Flora.
