272 Our Wild Grooseberries. [May, 
Dr. Parry’s Wyoming collection is a small-leaved form of it, 
which was mistaken for R. leptanthum ; but the flower, is per- 
fectly smooth, evidently white, and the style deeply cleft and 
hairy towards the base. I suspect that this species inhabits the 
northwestern shore of Lake Superior. Botanists visiting that 
district should look for a species with pure white flowers, a half- 
inch or less in length, with cylindrical tube, and stamens decid- 
edly shorter than the lobes. 
ER. cynosbati L. This dogberry, as the name denotes, is well 
marked by the usually strong prickles on the fruit, weak prickles 
on the stems (the thorns sometimes wanting altogether, but occa- 
sionally well developed), slender peduncles, and especially by the 
broadly bell-shaped tube of the greenish flower. It is common 
from Lower Canada to Illinois, and in the Alleghanies to Virginia. 
It is found occasionally with the berries as well as the stems wholly 
unarmed, 
In the rest of this section the calyx-lobes are decidedly longer 
than the short, bell-shaped tube ; and the berries are smooth and 
naked, purple, sweet and pleasant-tasted. 
R. gracile Michx. is the most distinct of them. It is well 
named on account of the slender peduncles, long and narrow ca- 
lyx-lobes, and almost capillary filaments. The latter are half an 
inch long, generally connivent or closely parallel, and soon con- 
spicuously longer than the oblong-linear calyx-lobes, which, 
being reflexed in anthesis, as in all these species, then expose 
the whole length of the stamens to view. The flower is whiter 
than in the rest of these species, having barely a slight tinge of 
green. The berry is pretty large, and is prized in cultivation, 
under the name of Missouri gooseberry. It is the R. Missouri- 
ense of Nuttall in Torrey and Gray’s Flora. It is also, as the 
figure shows, the R. niveum of Lindley in the Botanical Regis- 
ter; and from the character, it is probably the R. triflorum of 
Hooker’s Flora. It ranges from Tennessee and Illinois to the 
northern borders of Texas, and northwestward into the Rocky 
Mountains. In Michaux’s Flora the habitat is the mountains of 
Tennessee ; but I suppose it will not be found in the Alleghanies. 
A note with the specimens in his herbarium at the Jardin des 
Plantes records that they were collected “ in itinere Nashville.” 
R. rotundifolium Michx. is a species of the Alleghany Mount- 
ains, ranging northward and eastward into New York and the 
western borders of Massachusetts. Professor Dewey long 28° 
collected it near Williamstown, and Professor Tuckerman’s Am-
