Hot Springs, altitude 1,100 m., August 2 (No. 75(5). 



Two dei>;uii»erate specimeus iu blooui (several jilauts were seeu) wore collected 

 al)ove Fall Kiver Falls, altitude 1,000 ni., Juno 17. These two had narrow loaves, 

 more toothed than usual, and I took them at first to be G. nana Nutt., but they must 

 belong to (/. sijuarrosa (No. 757). 



Chrysopsis villosa (Pursli) Nutt. (U-u. ii, 151 (1818); Ainelhi'^ rillo-sus Pursli, Fl. ii,

 Aplopappua nuftaUii Torr. & Gr. Fl. ii, 242 (1812). Gypsum rocks above Hot Springs,

 Pursh, Fl. ii, 564 (1814); Aplopappus (?) spinitlosus DC. Prodr. v, 347 (1836). 



Kare: Hot Springs, altitude 1,100 ni., August 2 (No. 761). 



Solidago erecta Pursh, Fl. ii, 542 (1814). 



This is the >'. spcciosa angustata Torr. A: (ir., of Newton &, Jeniiey's Report. I refer 

 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 Elliott.' Gray- regards the two as the same 

 species notwithstanding the iiubescence attributed to the first. It is near S. speclosa, 

 but the primary veins are more or less jirominent and often looi)ed. 



Hilly places: Custer, altitude 1,700 m., August 16 (No. 762). 



Solidago missouriensis Nutt. Jonrn. Acad. Phil, vii, 32 (1834). 



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'. «n'ssoi(rie7JS(s, but should, if held sepa- 

 rate, be called variety glaherrlma {S. ijhiherrima Martens). Tlie true S. missouriennis 

 was also collected, viz, at Custer, altitude 1,700 ni., August 16 (No. 764). This was 

 named variety montana by Dr. Gray. Another form was found with broad leaves, the 

 lower often 1.5 cm. wide, the stem tall, 5 dm. high, panicle Avith uiiright branches 

 and large heads. It may be the variety extraria Gray, or, perhaps, a hybrid of iS'. 

 viissonriensis and the preceding, together with which it grew. Custer, August 16 

 (No. 7G5). 



Solidago rupestris IJaf. Ann. Nat. 11 (1820). 



Owing to the, meager material, the determination is doubtful. It may perhaps be a 

 narrow and thin-leafed form of S. nerotina Ait. Little Elk, altitude 1,100 m., June 28 

 (No. 766). 



Solidago canadensis L. Sp. I'l. ii, 878 (17.53).
