166 Rhodora [SEPTEMBER 
for June 1910, twice came under my notice in the Burlington Region. 
It was collected in swampy soil at the south end of Porters Swamp, 
Colchester, 2 August (Blake 2442), and later the same day a less typical 
form of it was collected (2456), growing with Polygonum amphibium f. 
Hartwrightii, an analogous state of another amphibious species, in a 
swampy spot near Barney Point, Colchester. The latter number 
was clearly intermediate between the typical form and good subsericea, 
and the inconstancy of the character of pubescence, coupled with the 
presumptive evidence of its ecological nature afforded by the habitat — 
more or less exsiccated swampy ground or meadow in each case — 
shows that the plant is better considered a forma than a variety.
