30 Mr. Tuckerman, on some Plants of New England. 
Hab. “In several low places towards the hills,”’ Pennsylvania, 
Bartram, (ex Kalm.) High Mountains of New York and Penn- 
sylvania, Pursh. Cedar Swamps, Columbus, Ohio, Sullivant. 
The plant from the last station, is the only one that I have seen. 
It seems to be the B. pumila of Willdenow, and is distinguished 
from B. glandulosa by the entire want of the resinous dots found 
on that species, as well as by its dense soft pubescence, mostly 
broad-ovate leaves and larger aments. ‘The present is possibly 
the more southern, and B. glandulosa the more northern of these 
allied species. Although it is enumerated in the Flora Boreali- 
Americana of Sir William Hooker, it would seem that the dis- 
tinguished author refers his own specimens rather to B. glandu- 
losa. ‘The citation ‘Canada, (Linn.)” I have not been able to 
identify ; our species being established on Kalm’s specimens, in 
the first Mantissa, where the habitat mentioned is ‘ America 
Septentrionalis.” 
B. euanpuLosa, (Michx.): humilis, ramis glanduloso-punctatis 
glabris, foliis obovatis basi integerrimis obtuse serratis glabris, 
amentis foemineis breviusculis lato-cylindraceis, squamis trifidis 
lobis oblongo-subovatis subeequalibus. E. T.—Michz. Fl. 2, 180, 
Pursh, Fl. 2, 622, Hook. Bor. Amer. 2, 156, and B. pumila, 
Hook. 1. ¢. ‘ 
Hab. ‘Circa lacus a sinu Hudsonis ad Mistassins,’’? Michaux. 
“ Canada,” Masson, in herb. Lambert. (White Mountains?) My 
specimen is that from the Lambertian herbarium, and a very 
beautiful one. ‘The species seems to be distinguished by its very 
glabrous habit, and its leaves (all in my specimen) cuneate and 
very entire at the base ; thus somewhat resembling small leaves 
of Crategus parvifolia. By the former character it is separated 
from B. pumila, and by the latter from the succeeding species. 
Among my White Mountain specimens are two, that may possi- 
bly belong to this species. 
B. Lirretxiana (mihi): humilis glabra, ramis resinoso-punctatis, 
foliis subrotundis grosse serratis petiolis nunc 4 lin. longis, amen- 
tis feemineis oblongo-cylindraceis, squamis trifidis lobis oblongo- 
obovatis intermedio longiori. 
Hab. White Mountains, in Oakes’s Gulf, between Mount Wash- 
ington and Monroe, and elsewhere in the alpine regions. A some- 
what erect shrub, with leaves which are from two to four times 
as large as those of B. nana. ‘To this last, which occurs on our
