1914] Fernald,— Variety of Polygonium cilinode 165 
I have found no records from Martha's Vineyard for either species, 
and they are not known on Block Island. 
For Ilex opaca this area forms the extreme northeastern limit 
of the species, which follows the coastal plain south to Florida, and 
extends inland to Missouri. It prefers moist soil in woods, but is also 
frequent southward on dry mountain slopes. 
Ilex glabra finds its extreme northeastern limit in southwestern Nova 
Scotia growing in the southern counties as far east as Halifax,! but 
there is a gap of 275 miles between there and Cape Ann, with no 
intervening stations. It follows the coast southward in swamps, 
moist sand, and low woods, to Florida and Louisiana. 
It is very interesting that these two allied species, with somewhat 
different soil-preferences, should be so evenly distributed over the 
same area in southeastern New England. Along with them here and 
there are over a hundred other coastal-plain plants, many of which 
find their northeastern limits here. The waterwashed glacial debris 
found in these New England sand-plains and kames is sufficiently 
like the recent coastal-plain further south, to furnish similar soil 
conditions, while further north on the New England coast these condi- 
tions disappear, and the plants with them. 
For information in regard to these ranges I am indebted to Dr. 
E. W. Sinnott, Messrs. A. C. Bent, S. N. F. Sanford and Professors 
J. F. Collins and M. L. Fernald.

Tue West VIRGINIAN VARIETY OF POLYGONUM CILINODE.— Poly- 
gonum cilinode Michx., one of the commonest plants of the Canadian 
Zone, ranges from Newfoundland to Athabasca and south into the 
Great Lake states, the mountains of Pennsylvania, and the cooler 
districts of New England. South of the Pennsylvania mountains it is 
very rare, but it has been reported as far south as North Carolina. 
The only material seen by the writer, however, from south of Penn- 
sylvania is Greenman’s No. 346 from Spruce Knob, West Virginia, 
where the plant is localized, as indicated by the citation in Mills- 
paugh's Living Flora of West Virginia (1913) of no other station in the 
state. But besides its isolation on Spruce Knob, the West Virginian
