Var. STRIGOSUM, n. var. 
One and a half to two feet tall. Stem clothed with stout, 
appressed hairs; leaves lanceolate to linear-lanceolate, obtuse, 
strigillose ; sheaths averaging half an inch long, densely strigose 
and long-ciliate ; bracts strigillose and ciliate; flowers whitish. 
Indiana: Indianapolis, along the White River (Britton); West 
Virginia: Preston Co., along the Cheat River (J. D. Smith); 
Canada: Gatineau River (Macoun). 
This well-marked variety we now have from three separate 
localities. Its almost white flowers, dense strigoseness and heav- 
ier habit separate it very clearly from the typical form.

13. POLYGONUM EPILOBIOIDES, Weddell, Ann. Sc. Nat. 3d ser.

ser. xiii. 253 (1849). 5 
Brazil: Matto-Grosso, on the Paraguay River (according to 
Meisner.) ; 
In every case in which Meisner had occasion to refer to this 
species, he was inclined to be very skeptical about its validity. 
It is admitted here in the hope that some certain facts concern- 
ing it may be obtained. Dr. Morong did not meet with it in 
Paraguay.
