somewhat ascending, 2.5 to 5 cm. long : fruit globose or ovoid, about 
1 cm. long. — Damp thicket, Groton, Connecticut, June 21 and Aug.

SOME EXTENSIONS OF RaANGE.— Ranunculus Allegheniensis, Britton, 
which is not mentioned in the recently published Flora of Vermont, 
was collected by the writer in Smuggler’s Notch, Vermont, July 5, 1897. 
Acalypha Virginica, L. var. gracilens, Muell, whose northern limit 
in Gray's Manual and Britton & Brown's Ill. Flora, is given as Rhode 
Island and Connecticut, was collected in Bourne on Cape Cod, 
September 15, 1901 ( G. G. Kennedy, M. L. Fernald, E. F. Williams), 
at Readville, Mass., near Boston, September 23, 1900 ( W. P. Rich, 
H. A. Purdie, E. F. Williams); and at Hampton Falls, N. H., Septem- 
ber 22, 1901 (B. L. Robinson, E. F. Williams). 
Cyperus Grayi, Torrey, given in Gray's Manual as occurring from 
Plymouth, Mass., to New Jersey, was collected by the writer at Plum

Prenanthes serpentaria, Pursh (not P. trifoliolata, Fernald) was

form common in this neighborhood and northwards. It is a smooth 
plant with the pappus included within the scales of the involucre. 
Westwood appears to be one of the most northern stations for 2. ser- 
| pentaria which is common southwards, and is distinguished from A. 
trifoliolata by its somewhat bristly involucre and by the very long 
pappus which exceeds the involucre by 1 to 2 lines. — EMILE F.

LOBELIA INFLATA x CARDINALIS. 
OAKES AMES. 
AN isolated plant of ZLobeZia inflata, L. was impregnated when the 
flowers were in a receptive condition with pollen of Zodelia cardinalis, 
L. The flowers were not netted nor in any way protected from insect
