Solidago serotina Ait. Hort. Kew. iii, 211 (1789), not Willd, 
Here and there, in copses: Haney’s ranch, August 5; Cody’s Lakes, August 10; 
South Dismal River, August 12 (No. 1648). 
Solidago canadensis L. Sp. Pl. ii, 878 (1753). 
A hirsute form approaching the varieties scabra and procera of Torrey & Gray: 
Thedford, September 12; Mullen, September 14 (No. 1757). 
Solidago canadensis gilvocanescens var. nov. 
Low, 3 to 4 dm. high; leafy; leaves 3 to 6 em. long, oblanceolate to lanceolate, 
remotely serrate above the middle or entire; the whole plant finely puberulent- 
canescent and of a yellowish hue, often somewhat scabrous; inflorescence dense, 
contracted, with short recurved branches; heads smaller than in S, canadensis. 
It resembles somewhat the varieties canescens and arizonica in the pubescence, but 
differs from both in being much lower and more leafy. The leaves resemble some- 
what those of the latter, but the bracts are very different. It was growing in sandy 
soil near water, Cody’s Lakes, Hooker County, Nebr. (No. 1662). Specimens of this 
variety are preserved in the National Herbarium, from the following localities: 
Dodge City, Kans., August 19, 1890, B. B. Smyth, No. 162; Montana (locality not 
given), L. F. Ward (this is labeled S, nemoralis). No. 34 of Nicollet’s Northwestern 
Expedition, labeled S. incana f. (?) Torr. & Gr., collected July 25, 1839, on saline, 
swampy margins of the Lake of the Woods near Devil’s Lake, Minn., is a form with 
narrower leaves. 
Solidago nemoralis Ait. Hort. Kew. iii, 218 (1789). 
Two forms were collected. One is about 6 to 8 dm. high with an open panicle, 
resembling somewhat a large form of 8. canadensis; evidently scabrous: Thedford, 
September 8; Cody’s Lakes, August 9 to 12 (No. 1663). 
The other form is lower, 4 to 6 dm. high, with a narrow, nearly spicate panicle: 
Thedford, September 8 (No, 1751). 
Solidago mollis Bartl. Ind. Sem. Gatt. 5 (1836); Solidago incana Torr. & Gr, FI. 
ii, 221 (1841); S. nemoralis incana Gray, Proc. Amer, Acad. xvii, 197 (1882). 
This is a good species, and perfectly distinet as well from 8. nemoralis as from 
S. radula, to which it has been referred. 
My plant is low, 2 to 3 dm, high, very leafy; leaves thick, triple-nerved, diminish- 
ing upward; the lower 5 to 7 em. long and 2 to 3 em. wide, obovate, coarsely and 
remotely serrate scabrous and somewhat canescent; panicle short, of short recurved 
branches; heads larger and with broader bracts than in S. californica, lower forms 
of which it resembles, Specimens in the National Herbarium collected by Orcutt 
(No, 89, partly) in California and by C. G. Pringle, at Tehachipi Pass, California, 
resemble this in growth, but have the pubescence of 8, californica. The specimens 
in the National Herbarium are as follows: Whipple Expedition, Antelope Hill, on 
the Canadian River; 8, M. Rothammer, No. 488, Upper Missouri; two sheets col- 
lected by L. F. Ward, in Montana, 1883; two sheets by Dr. Wilcox, Nebraska, 1887; 
P. A, Rydberg, No. 157, western Nebraska, 1891, A specimen, collected by Dr. 
Palmer in Arizona, 1869, has no name. Near the railroad, Mullen, September 18 
(No. 1770). 
Solidago rigida L. Sp. Pl. ii, 880 (1753), 
West Cody’s Lake, August 10; Plummer Ford, August 22 (1666). 
Buthamia graminifolia (L.) Nutt. Gen. ii, 162 (1818); Chrysocoma yraminifolia L. 
Sp. Pl. ii, 841 (1753); Solidago lanceolata L. Mant. 114 (1767). 
Thedford, September 8 (No. 1788). 
Eriocarpum spinulosum (Pursh) Greene, Erythea, ii, 108 (1894); Amellus spinulo- 
sus Pursh, FI. ii, 564 (1814). 
Throughout the sand hills, but local: Thedford, June 19, August 9; Dismal River, 
June 27; Plummer lord, July 4 to 8; Mullen, July 26 (No, 1403),
