Cireza lutetiana L. Sp. Pl. i, 9 (1753). 
Common in shaded, wet places: Plummer Ford, July 3; Forks of Dismal River, 
July 11 (No. 1468). 
Cinothera biennis L. Sp. Pl. i, 346 (1753). 
Common on the banks of the Middle Loup River at Mullen, July 17, 18; also in 
Grant County, July 31 (No. 1578). Grades into the next by several forms. 
Cinothera biennis parviflora (L.) Torr. & Gr. F1.i,492 (1840); (2. parviflora L. 
Sp. Pl. ed. 2, i, 492 (1762). 
Flowers very small, of the size of the next species. Mullen, July 18; Middle Fork 
of Middle Loup River, July 26; South Dismal River, August 14 (No. 1573). 
Ginothera sinuata L. Mant. ii, 228 (1767). 
All my specimens are low, generally less than 1 dm, high, the leaves sinuately 
toothed or entire. This is the only form growing in Nebraska. Thedford, June 15 
(No. 1302). 
Ginothera rhombipetala Nutt.; Torr. & Gr. FI. i, 493 (1840), 
This is common on the sand hills near Phimmer Ford; July 6 to 8 (No. 1510). 
Ginothera albicaulis Pursh, FI. ii, 733 (1814); ). pinnatifida Nutt. Gen. i, 245 
(1818). 
C. albicaulis of Fraser’s Catalogue is a nomen nudum, and the first plant described 
under this name is the present, which Mr. Pursh inaccurately supposed to be identi- 
cal with that of Fraser’s Catalogue. 
Rare in the region, only a few specimens secured at Mullen, July 15 (No. 1293). 
G&nothera pallida Lindl. Bot. Reg. xiv, t. 1142 (1828); Ge. albicaulis Nutt. Gen. i, 
245 (1818), not Pursh. 
The common form in Nebraska has a tall, upright white stem and narrower, linear 
or Jinear-lanceolate, or linear-oblong leaves, with mostly entire margins. It gener- 
ally grows on prairie soil, Mullen, July 19 (No. 1586). 
Ginothera pallida latifolia var. nov. 
Leaves broad, 6 to 9 em. long and 2 to 5 cm, wide, remotely dentate, cinereous on 
both sides; stem diffuse and much branched. 
It grows in sand draws and on the banks of rivers. Mullen, July 17; Grant 
County, August 4 (No. 1544). No. 112 of my western Nebraska collection is the 
same. In aspecies as variable as (2, pallida, perhaps the number of varietal names 
should not be increased; but this is so remarkable and so different from the common 
form, that I feel justified in adding another name. It is true that there are some 
intermediate forms, as for instance No. 1813 of tis collection (Mullen, July 17), but 
such forms are very rare. If no intermediate forms were found, we should call them 
distinct species. 
G5nothera serrulata Nutt. Gen. i, 246 (1818). 
A common plant throughout the region. Thedford, June 16; Plummer Ford, July 
3 (No. 1303). 
Gaura coccinea Pursh, FI. 1i, 783 (1814). 
Rather common on the prairies. Thedford, June 17 (No, 1348), 
Gaura parviflora Dougl.; Hook. Fl. Bor. Amer. i, 208 (1834). 
Rare: only one poor specimen secured, at Plummer Ford, July 3 (No. 1460), 
Gaura biennis L.Sp. P1. i, 347 (1753). 
Rare: on banks of Middle Loup River, above Seneca, September 16 (No. 1777).
