It may interesting in this connection that some one 
(perhaps Dr. A. Gray?) at one time had intended publishing 
what is a good specimen of P. ammophila Greene. A specimen in 
the N. Y. Botanical Garden Herbarium, originally from the Torrey 
Herbarium, collected Aug. 25, 1929, at Troy, N. Y. is thus labelled 
as indicated below. The following annotation is appended to the 
sheet. 
“Polygonum hirsutissimum (mihi) a new one! Description. 
Stamens 5, stigmas 2, style 2 cleft, cylindric-ovate, thick round 
obtuse: general bracts about 2-flowered, each flower with a bract 
also. Stem assurgent simple or branching very hirsute; leaves 
oblong linear-lanceolate overy hirsute, tapering gradually to the 
obtuse or subacute apex, subsessile subcordate at the base scabrous 
ciliate, stipules hirsute, long ciliate; peduncle smooth or nearly 
so, 12-24 inches long. Grows in great plenty in company with 
P. mite and amphibium var. terrestris in a lot 1 mile NNE of Rens. 
School. August.” 
PERSICARIA NEBRASCENSIS Greene, Leaflets Vol. 1., p. 47. 
AQUATIC OR SUBAQUATIC PHASE. Plant with a creeping root- 
stock which is rather thick: Ochrea of the upper leaves mem- 
branous as in the terrestrial and slightly hirsute when emerging 
from the water. Leaves of the same shape as the terrestrial, but 
perfectly glabrous throughout, obtuse, rounded or subcordate at 
the base, and acute at the apex, broadest little below the middle, 
elliptic to elliptic oblong. Internodes 1.5-4 cm. long in branches 
and 4-11 cm. on the rhizome. Petioles short, .5—3 cm. long; bracts 
triangular acute, glabrous: seed almost lenticular, black. Peduncles 
short 1.5—-2 cm. long: spike 1.5—2 cm. long. 
The lower leaves are especially glabrous, and the upper re- 
duced, sometimes appressed scabrous on the margin. They are 
smaller than in P. ammophila and on the terrestrial less hirsute. 
It is more than likely that typical aquatic phases will be found 
to have the habit and foliage resembling that of P. ammophila. 
The lower leaves of the specimen described are normally aquatic 
but the plant has recently emerged from the water the upper
