Juncus has been verified by Mr. Frederick V. Coville, and that of the 
grasses by Prof. I’, Lamson Scribner and Mr. L. H. Dewey. 
Acknowledgment is also due to the Academy of Natural Sciences of 
Philadelphia for the loan of specimens for comparison. All the plants 
have been compared with the collections in the National Herbarium

RANUNCULACES. 
Clematis ligusticifolia Nutt.; Torr. & Gray Fl. i, 9 (1838), 
Rare; on a billside near Plummer Ford, Dismal River, August 22, 24 (No. 1717). 
Anemone cylindrica Gray, Ann. Lye. N. Y. iii, 221 (1836). 
Banks of Dismal River, south of Thedford, June 27 (No. 1431). 
Thalictrum purpurascens L. Sp. Pl. i, 546 (1753). 
A tall, puberulent form with thick leaves, which are paler beneath, was very 
common among the bushes along the streams. On Middle Loup River at Natick, 
June 20, and Norway, June 22, 23; on Dismal River, south of Thedtord, June 27; ; at 
Plummer Ford, July 3; South Dismal River, August 14 (No. 1413), 
Batrachium divaricatum (Schrank) Wimm, Fl. Schles. 10 (1841); Ranunculus 
divaricatus Schrank, Baier. Fl. ii, 104 (1789). 
The plant seems to be nearest this species, which has been regarded as the same as 
hk. circinatus Sibth.; but my specimens differ from European ones of that species in 
having more flaccid leaves with longer and finer divisions. In the latter the lobes 
are short and rigid, spreading in a circle around the stem. ‘The Nebraska specimens, 
viz, my No. 4 from Lodge Pole Creek (1891) and those of the present collec tion, have 
the very fine divisions more or less ascending. ‘The sessile leaves and the much 
longer peduncles distinguish it from forms of Batrachium trichophyllum. Tt was col- 
lected in Middle Loup River, near Thedford, June 16, and in Dismal River, near 
Plummer Ford, July 3 (No. 1385), It was also seen in the lakes of Grant County. 
Cyrtorrhyncha cymbalaria (Pursh) Britton, Mem. Torr. Club. v, 161 (1894); Ran- 
unculus cymbalaria Pursh, Fl. i, 892 (1814), 
The oldest name for this species, however, seems to be Ranunculus salsuginosus 
Pallas.? According to Ledebour?® 2. salsuginosus Pallas,? and R. salsuginosus DCA 
are not the same. According to the same author, the former is 2, eymbalaria Pursh, 
and the latter &, plantaginifolius Murr. and R. ruthenicus Jacq., a similar, but 
larger, plant. Pallas in his ‘“ Reise,’’ does not give a description under the name 
RK. salsuginosus, but bases this on an already described and figured plant, giving as 
synonyin “ Ranunculus repens flore in caule singularis, fol. varie sectis; Amman ruth, 
107, tab, 13, fig. 2.°. As I have no access to Amman’s Stirpitim Rariorum Rutheno, 
Ican not tell whether this is our B, cymbalaria or not. I am, howey er, strongly. 
inclined to believe that Ledebour is right, as he cites the synonym given above, 
while neither De Candolle nor any American author, as far as I know, uses it as a 
reference to 2’. salsuginosus. De Candolle gives it as a synonym of I. eymbalaria. 
Common on moist, sandy soil; near Thedford, June 15, 16, and Whitman, August 
1 (No. 1884). 
‘On my return from Washington, I visited Columbia College arfd Harvard Uni- 
versity, staying one week at each place. I hereby extend my thanks to Dr. N. L. 
Britton and Dr, B. L. Robinson for the use of the herbaria and botanical libraries of 
their respective institutions, and to the former and Mr. J. M. Greenman for kind 
assistance given. The valuable notes taken at both places have been incorporated 
in the following catalogue.
