form I think most typical has thin, nearly smooth leaves. The lower stipules are 
generally narrow and often entire, while the upper are broad and glandular-toothed. 
Thedford, June 21; Dismal River, June 28; Plummer Ford, July 5 (No. 1354), No. 
1313 is a similar form, but with smaller leaflets; Thedford, June 16. No. 1849 is a 
form similar to the first, but with the leaves more hairy beneath, the fruit larger, 
spherical, and bright red, the stipules mostly narrow; Mullen, August 17; Thedford, 
September7. The other forms collected have the leaves distinctly pubescent beneath 
and even somewhat glandular. In one the fruit is large and spherical, the sepals 
sometimes lobed and deciduous; in the other the fruit is smaller and pear-shaped, 
the sepals persistent. Notwithstanding this, I believe they are but forms of the same 
species. The first of the two (No. 1848) was collected at Natick, June 20; Dismal 
River, June 29; the other (No. 1606) near the Forks of Loup River, June 27. 
Cratzgus coccinea L. Sp. PI. i, 476 (1753), 
In my specimens the corymbs are slightly villose. The trees were small, the tall- 
est only about 4 m. high. Near the Forks of Dismal River, July 11 (No. 1528), 
RIBESIACE. 
Ribes floridum L’Her. Stirp. i, 4 (1784). 
My specimens are more tomentose than usual. Common along the streams: Nor- 
way, June 22; Dismal River, June 27 (No, 1415), 
Ribes aureum Pursh, Fl. i, 164 (1814). 
The form with black fruit was not uncommon on the hillsides near the streams. 
Norway, June 22; Natick, June 20; Plummer Ford, July 38; Mullen, July 27 (No. 
1366). 
The form with golden-yellow fruit was found only on the Middle Fork of Middle 
Loup River, July 27 (No. 1601). 
Ribes gracile Mx. FI. i, 111 (1803). 
Only a few bushes were found near Crumb’s horse range, on the Dismal River, 
_ July 10 (No. 1523). 
HALORRHAGIDACE. 
Myriophyllum spicatum L. Sp. Pl. ii, 992 (1753). 
What I take as the typical form was collected in leaf only on a lake in Grant 
County, northwest of Whitman, September 19 (No. 1785). Another form having 
smaller leaves, with shorter, more or less fleshy lobes, was found in bloom in Swan 
Lake, 25 or 30 miles south of Whitman, August 7 (No. 1784). 
Hippuris vulgaris L. Sp. Pl. i, 4 (1753). 
This is new to the State. The only locality known is a swamp, near Haney Bros.’ 
ranches, 25 miles south of Whitman; August 4 (No. 1645). 
LYTHRACES. 
Lythrum alatum Pursh, Fl. i, 334 (1814), 
Common in meadows: Plummer Ford, July 3; Forks of Dismal River, July 12 
(No, 1468). 
ONAGRACES. 
Epilobium lineare Muhl. Cat. 39 (1813). 
In the western part of the region: Middle Fork of Middle Loup River, July 26; 
northeast of Whitman, July 31 (No. 1603). 
Epilobium adenocaulon Hausk. (Est. Bot. Zeit. xxix, 119 (1879). 
Along the banks of Middle Loup River, north of Mullen, July 16 to 19. No. 1556 
is a more simple and broad-leafed form; No.1576,a more branched and narrow- 
leated form.
