Pursh, Fl. ii, 559 (1814). 
Ilot Springs, altitude 1,100 m., August 2 (No. 756). 
Two depauperate specimens in bloom (several plants were seen) were collected 
above Fall River Falls, altitude 1,000 m., June 17. These two had narrow leaves, 
more toothed than usual, and I took them at first to be G. nana Nutt.,lut they must 
belong to G, squarrosa (No, 757). 
Chrysopsis villosa (Pursh) Nutt, Gen, ii, 151 (1818); Amellus villosus Pursh, Fl. ii,

Aplopappus nuttallit Torr. & Gr, V1. ii, 242 (1842). Gypsum rocks above Hot Springs,

Eriocarpum spinulosum (Pursh) Greene, Ery thea, ii, 108 (1894); Amellus spinulosus 
Pursh, Fl. ii, 564 (1814); Aplopappus (2) spinulosus DC. Prodr, v, 347 (1886). 
Rare: Hot Springs, altitude 1,100 m., August 2 (No. 761). 
Solidago erecta Pursh, Fl. ii, 542 (1814). 
This is the 8. speciosa angustate Torr, & Gr., of Newton & Jenney’s Report. Lrefer 
it doubtfully here. It does not agree with the original description by Pursh, being 
perfectly smooth except the margins of the leaves, which are scabrous. It agrees 
well with the description of S, erecta by Flliott.!. Gray? regards the two as the same 
species notwithstanding the pubescence attributed to the first. It is near S, speciosa, 
but the primary veins are inore or less prominent and often looped, 
Hilly places: Custer, altitude 1,700 m., August 16 (No. 762). 
Solidago missouriensis Nutt. Journ. Acad, Phil. vii, 32 (1884), 
Very variable. The form held as the typical one, that is, stouter with spreading 
panicle of recurved branches, was collected at Custer, altitude 1,700 m., August 14 
(No. 763), This is, however, not the original S. missouriensis, but should, if held sepa- 
rate, be called variety glaberrima (S. glaberrima Martens). The true S, missouriensis 
was also collected, viz, at Custer, altitude 1,700 m., August 16 (No. 764). This was 
named variety montana by Dr. Gray. Another form was found with broad leaves, the 
lower often 1.5 em, wide, the stem tall, 5 dm. high, panicle with upright branches 
and large heads. It may be the variety ertraria Gray, or, perhaps, a hybrid of 8, 
missouriensis and the preceding, togetier with which it grew. Custer, August 16 
(No. 765). 
Solidago rupestris Raf. Ann. Nat. 1d (1820). 
Owing to the meager material, the determination is doubtful. It may perhaps be a 
narrow and thin-leafed form of 8. serotina Ait. Little Elk, altitude 1,100 m., June 28 
(No. 766). ‘ 
Solidago canadensis I.. Sp. Pl. ii, 878 (1753).

Custer, altitude 1,700 m., August 1 (No. 1207). 
Solidago nemoralis Ait. Hort. Kew. iii, 215 (1789). 
My specimens are more or less scabrous, some have axillary clusters and resemble 
somewhat S. bicolor concolor. Custer, altitude 1,700 m., August 16 (No, 768).
