 Rep. 1870, 479. £. f/lomeratum, Gray, Am. Jour. Sci. ser. 2, xxxiv. 

 225, non DC. £. glomeratum, var. virgatum^ Porter & Coulter, Fl. 

 Colorad. 102. Hispida, baud caaesceus ; caule simplicissimo cum 

 thyrso angustissimo stricto (s»pius ultrapedali) foliato demum 2-3- 

 pedali ; cymulis etiam fructiferis perbrevibus foliis fulcrantibus aii- 

 gusto-liuearibus brevioribus ; foliis caulinis inferioribus radicalibusque 

 augustissime spathulatis ; corollie limbo lin, 2 lato, foruicibus latioribus 

 quam loiigis ; nuculis vix ultra sequilineam lougis lato-ovatis obtusis 

 sajpe nitidulis dorso parce papillosis cajterum Itevibus. — This we have 

 only from the eastern slopes of the Rocky Mountains in Colorado, and 

 it does appear to be a distinct species. The slender leaves subtending 

 the cymes of the virgate thyrsus are an inch or two long, all but the 

 uppermost several times longer than the flower-clusters. 



K. GLOJiERATA. Cynoglossum glomeratum^ Pursh, Fl. ii. 729. 

 3Igosotis glomerata, Nutt. Gen. i. 112; Hook. Fl. Bor.-Am. ii. t. 162. 

 Rochelia glomerata, Torr. Ann. Lye. N. Y. ii. 225. Eritrichium 

 glomeratum, DC. Prodr. x. 131 ; Porter & Coulter, Fl. Colorad. 102. 

 E. glomeratum, var. hispidissimum, Torr. Bot. Mex.' Bound. 140. 

 Valde hispida ; caule (cum thyrso oblongo interrupto demum aperto et 

 in spicis fructiferis folia multo superantibus evoluto) semipedali ad 

 sesquipedalem ; foliis plerisque spathulatis, radicalibus saltern pube 

 minuta inter setas basi demum papillosas pi. m. canescentibus ; corolla 

 limbo 2-3 i- lin. lato, fornicibus a^quilongis ac latis ; nuculis crassioribus 

 1^-2 lin. longis ovatis versus apicera obtusiusculum angustatis, dorso 

 pi. m. corrugate. — This belongs rather to the plains along the eastern 

 base of the Rocky Mountains, from Saskatchewan to New Mexico, but 

 extends westward to the interior of Washington Territory, and to 

 northern parts of Arizona. It occurs both with short and with longer 

 style. 



= = Minus hispida, nana, raulticaulis e caudice perenni ; foliis saltern 

 radicalibus pube moUi strigoso-sericea incanis cum setis parum rigidis

K. SERiCEA. Eritrichium glomeratum, var. kumile, Gray, Proc. 

 Am. Acad. x. 61, & Fl. I.e., magna parte. Nuculoe oblongo-ovat£E, 

 obtusa?, obcompressse, dorso subrugoso-tuberculatai. — Alpine and sub- 

 alpine, on mountains from Colorado and Utah to Oregon and Montana, 

 and probably in the British Possessions. There are less canescent 

 specimens from the Saskatchewan region and also from the higher 

 Sierra Nevada (and uncertain as to the duration of the root) which
