cordate, or unequally rounded at the base. ‘The same proportions 
as to size obtain with respect to the spathe, spadix and head of fruit of 
the two forms. ‘The seed of the two forms germinate in exactly the 
same manner. ‘The germination has been described by Dr. Th. Holm

Peltandra virginica var. angustifolia (Raf.) comb. nov. P. angusti- 
folia Raf.—“ Leaves hastate cordate narrow oblong, lobes obtuse" . . 
(Raf. l. e. 89). What has been said in the case of var. heterophylla 
might be repeated of this form. In June, 1906, I observed in Nan- 
jemoy Creek, Md., some plants growing with P. virginica which ap- 
proach nearly the concept of P. angustifolia. The leaves are mostly 
rounded at the base, but occasionally halberd-shaped; the blades are 
2.5-3 dm. in length and barely 4 cm. wide. So far as external char- 
acters are concerned this form appears to be farther removed from the 
type than var. heterophylla. 
Type specimens have been deposited at the Gray Herbarium.

THE NORTH AMERCAN VARIATIONS OF LYCOPODIUM 
CLAVATUM. 
M. L. FERNALD and C. H. Bissett. 
In 1831 Greville & Hooker described from the Canadian Rocky 
Mountains a I-spiked variety of Lycopodium clavatum as 
“Var. B. monostachyon; spica solitaria, pedunculis brevibus" from 
` “The Rocky Mountains, north of the Smoking River, in lat. 56°. 
North America. Mr. Drummond.— The variety 8. is a remarkable 
one. ‘The whole plant is more compact, the leaves less dentato-ciliate,
