The leaves, the calyx, externally as well as internally, and the 
capsules are markedly pubescent. 
Beadle ! describes from Tennessee as a species, P. intectus, but it is 
only a variety which has the leaves, capsules, and outer surface of the 
sepals glabrous or relatively so.?

The differences are thus comparable to those between P. coronarius 
and its variety, tomentosus, above.

THE AMERICAN VARIATIONS OF LYCOPODIUM 
ANNOTINUM. 
M. L. FERNALD. 
THE disposition of the American plants ordinarily passing as 
Lycopodiüm annotinum L. has often been a source of some perplexity 
to students in our Northern States and British America. As com- 
monly interpreted the species consists with us of the so-called typical 
L. annotinum, with leaves spreading, and var. pungens Desv., with 
shorter more rigid erectish leaves. The chief difficulties which field- 
botanists in the North have encountered have arisen from the fact 
that in the region from Newfoundland to the Great Lakes and eastern 
Pennsylvania there are two quite pronounced variations of L. annoti- 
num with spreading or even reflexed leaves. A study of the material 
in the Gray Herbarium and the Herbarium of the New England 
Botanical Club, 184 numbers, shows that the species in North America 
falls into four, instead of two, rather pronounced tendencies, the typi- 
cal form of the species crossing the continent, the three varieties each 
with more restricted distribution. The following synopsis may be 
of interest to others as a basis for the recognition of these four varia- 
tions.

2 Indeed, Beadle, 1. c., says of it: ‘‘From P. latifolius Schrad. this species may be 
recognized by the glabrous or glabrate leaves and by the absence of pubescence on the 
hypanthium and exterior surface of the sepals.”
