338 Plants of the Rocky Mountains— Supplement III 



a. Incance ; calycis negmentis dilalatis suhintegris. 



C. FOLioLosA, Hook. & Am. Floccoso-tonientosa, tomento e pilis 

 ramosissimis ! Caules suffruticosi cum tbliis adultis quandoque glabrescen- 

 tes : galea ultra segmenta calycis spathulato-oblonga saepius retusa leviter 

 exserta.— The peculiarity of the pubescence is indicated in Bot. Mex. 

 Bound. Survey, p. 118. 



C. LAN ATA, Gray in Bot. Mex. Bound., 1. c. Herbacea, tomento arach- 

 noideo appresso albo-lanata: flores fere C.foliosoe, sed majores. 



b. Cinereo'puherulce vel suhtomentosce ; calycis segmentis scepissime hifi- 

 dis ; galea exserta. Folia supra nunc glabra. 



C. INTEGRA, Gray in Bot. Mex. Bound. 1. c. Caulis laxe tomentosus: 

 folia (sjepms tomentulosa) omnia integeirima, vel floralia sublobata, raro 

 trifida: flores sesquipollicares, galea inajore et labio breviore quam C. 

 purpnreoe.—Bes\des the numbers already cited, this is No. 244 of Parry's 

 Rocky Mountain collection (a dwarf or subalpine form) ; and my C. (omen- 

 tosa, from Mabibi, Arizona, Thurber, appears to be a more' tomentose 

 state of the same species, the flowers in the specimen not well developed. 

 It IS closely related to C. purpurea, and perhaps runs into it. To that, at 

 least, I now refer the undistributed specimens of Wright's first collection. 



C. PURPUREA, Don. Caulis tomentulosus vel cineretis : folia pubera vel 

 glabrata, superiora vulgo cum floralibus trifida seu laciniata : flores polH- 

 cares, labio minus quam in aflSnibus abbreviato (2-2^ lin. longo). Flo- 

 ral leaves varying from cherry-red to flesh-color, or light yellow." Lower lip 

 of the corolla by no means half the length of the galea in well developed 

 flowei-s. To this species belongs C. angusiifoha. Gray in Bot. Mei. 

 Bound. 1. c, excluding the synonymy, and excluding the plant of H. 

 Engelraann from Bridger's Pass, the latter being C. miniata. It is, ac- 

 cordmgly, Wright's No. 1491 and 1492, and Lindheiraer's 488 and 669. 

 ^.,-^-r ^<'^"« (plerisque 3-5-Jidis lobis linearibus) floralibus apice nee 



''''•''° -J coloratis. Calyx aut cequaliter aut antice profmdius fissus, 



los(B vel subcin 



lin. longa. 



^ C. BREviFLORA, Gray, PI. Parry, No. 243. (Euchroma breviflora, Nutt 

 m herb. Philad.) Spithamaea, spica densa, florescente vix polhcari; 

 calyce ovoideo-oblongo, lobis lanceolatis ; corollse lutea tubo kre incluso, 

 labio inferiore triplicato-saccato breviter trifido, lobis oblongis obtusis.-- 

 Rocky Mountams, Nutlall, Parrv, No. 243. A well-marked species of 

 this genus; the lip of the corolla" about as long in proportion to the galea 

 as in C. sessiliflora, but more trisaccate,— therefore one of the transiUous 

 to Orthocarpus. The calvx in flowers of the same spike is sometimes 

 about equally cleft behind 'and before, and sometimes split in front while 

 ihe posterior cleft is no deeper than that between the lateral lobes. 



t tie third section of Orthocarpus and Castllleia.
