Epilobium drummondii Haussk. Monogr. Gatt. Epil. 271 (1884). 
Two forms were met with. One was tall, sometimes 5 din, high, stringy, with nar- 
row leaves: Rochford, altitude 1,700 m., July 12 (No, 697). The other was lower, 
with broader, ovate-lanceolate leaves sinuately toothed, sessile and half-clasping. 
Sips Spring, in the Limestone District, altitude 1,800 m., July 28 (No. 698). 
Epilobium hornemanni Reichenb. Icon, Crit. 1, 73 (1824). 
Only afew depauperate plants collected at Sips Spring together with the preceding 
(No. 699). 
Epilobium paniculatum Nutt.; Torr. & Gr. FL. i, 490 (1sct), 
Custer, altitude 1,700m., August 21 (No. 574), 
Gayophytum ramosissimum Torr. & Gr. FL. i, 518 (1840),

(No. 700). 
GGinothera biennis L. Sp. P1.i, 346 (1753). 
This is evidently native in western Nebraska, as well as in the Black Hills. In 
general habit it differs much from 0, biennis of Europe. Rochford, altitude 1,600 m., 
July 11 (No. 701). 
Another form, somewhat like the preceding, but not strigose, was also found. The 
pubescence 1s fine, silky, appressed ; radical leaves many, obovate, about 2.5 em. long; 
calyx tube nearly 4 cm. long, lobes linear-lanceolate about 1.25 em. long; petals 
broadly obovate; pod linear-oblong, only a little narrower upward. Custer, alti- 
tude 1,700 1m., July 15 (No. 702). 
GSnothera sinuata L. Mant. 228 (1767). 
Only a few small specimens secured at Hot Springs, altitude 1,100 m., June 14 
(No. 703). 
GGnothera albicaulis Pursh, Fl. ii, 783 (1814), not Nutt.; Ge. pinnatifida Nutt. 
Gen. i, 245 (1818). 
The plant is very variable: Hot Springs, altitude 1,100 m., June 16; Herinosa, 
altitude 1,000 m., June 23; Custer, altitude 1,700 m., July 16 (No. 704). 
Ginothera pallida leptophyNa (Nutt.) Torr. & Gr. FI. i, 495 (1838); (2. leptophylla 
Nutt.; Torr. & Gr. loc. cit,, as synonym; (:, albicaulis Nutt. Gen. i, 245 (1818), not 
Pursh. 
The typical GQ). pallida has more or less runcinate-toothed leaves. Broken soil: 
Custer, altitude 1,700 m., July 15 (No. 705). 
C8nothera coronopifolia Torr. & Gr. Fl. i, 495 (1840). 
Sandy soil: Custer, altitude 1,700 m., June 4; Hot Springs, altitude 1,100 m., 
June 15 (No. 706). 
GSinothera cespitosa Nutt. Fraser’s Cat. (1813). 
Battle Mountain, east of Hot Springs, altitude 1,200 m., June 15 (No. 707). 
G3inothera serrulata Nutt. Gen. i, 246 (1818), | 
Fall River Falls, altitude 1,000 m., June 17; Rapid City, altitude 1,050 m., June 25; 
E1k Canyon, altitude 1,200 m., June 29 (No. 708), 
Gaura coccinea Pursh, FI. ii, 733 (1814). 
Hot Springs, altitude 1,100 m., June 13 (No. 709). 
A form, perfectly smooth, with white bark which peels off like that of G¢nothera 
pallida, was collected at Custer, altitude 1,700 m., July 15 (No, 710). This form is 
also found in western Nebraska, where I collected it in 1890 and 1891. 
Gaura parviflora Dougl.; Hook. Fl. Bor. Amer. i, 208 (1834). 
Hot Springs, altitude 1,050 m., August 2 (No. 711). 
‘Gray includes in his list, in Newton & Jenney’s Report, also GQ). chrysantha Mx, 
(G. pumila), which must be an error, as that plant is strictly an Atlantic coast spe- 
cles.
