1917] Pease,— Taraxacum ceratophorum in New England 111 
In our current manuals Oenothera pumila is somewhat ambiguously 
described as “puberulent”’ or “sometimes finely puberulent.” The 
extensive series in the Gray Herbarium and the herbarium of the 
New England Botanical Club, with the exception of the above cited 
specimens, is invariably strigillose or puberulous with appressed or 
sometimes merely incurved hairs, generally dense but sometimes sparse 
in age (although never quite lacking), and is at once distinguishable 
from var. rectipilis. The latter is probably the only form occurring 
on the southern shore of the Baie des Chaleurs in New Brunswick; 
the two collections from that region are the only specimens of either 
form of the species from New Brunswick which I have examined. 
At the Ontario locality var. rectipilis apparently occurs with the typi- 
cal form, since one of the four specimens representing Macoun 44,466 
in the Gray Herbarium is clearly referable to true O. pumila. In all 
features but pubescence var. rectipilis seems quite indistinguishable 
from ordinary 0. pumila L.— S. F. BLAKE, Stoughton, Massachusetts. 
A Dtacnostic CHARACTER OF NUPHAR MICROPHYLLUM.— The 
writer has often noticed in collecting Nuphar microphyllum ' that the 
fruit is quite naked at base, that is, without the rings of partly decayed 
filaments which abound at the, base of the fruit in all our other species 
of the genus. This character, which apparently is not recorded in the 
descriptions of the species, is of great diagnostic value, especially 
in separating N. microphyllum from small forms of N. rubrodiscum. 
The character, although not mentioned in the description, is well 
brought out in the photograph of fruit of N. microphyllum in Miller & 
Standley’s paper on “The North American Species of Nymphaea.” ? —

TARAXACUM CERATOPHORUM IN NEw ENGLAND.— On 27 July, 1909, 
a single plant of a Taraxacum clearly differing in appearance from the 
familiar New England species was collected by the writer in a moist 
gully (at an elevation of about 4500 feet) in King’s Ravine, Mt. Adams,
