Polygonum allocarpum may easily be recognized by its large leaves, 
lack of glaucosity, and large shiny achenes. Its nearest relative is 
perhaps one of the larger forms of the P. aviculare alliance, from which 
it is at once distinguished by achenial characters alone. From P. 
Fowleri Robinson, with which it has been confused, it differs in the 
much larger fruit, the thinner more veiny and usually larger leaves, 
the longer more persistent ocreae, and the more or less ascending 
habit. From P. Rai it is too widely different to require detailed 
comparison.

FURTHER NOTES ON THE ORCHIDS OF THE AsQuAM Regcion.— In 
my note on the orchids of the Asquam Lake, N. H., region, printed in 
Ruopora for March 1917, no mention was made of finding Pogonia 
affinis, although a specimen suspected of being this species had been 
collected. More recent investigation (June 29-July 9, 1917) proves 
the plant in question to be P. affinis. This species has not, so far as I 
know, been previously reported from New Hampshire. As only 
three plants (two in blossom) were found it did not seem advisable 
to do much collecting, although I took one specimen for my herbarium. 
Unfortunately the blossom was lost, but the.leaves are still preserved 
in rather poor condition. I also have two specimens of the capsule.
