Castilleia. SCROPHULARIACE^. 297 



mountains of Arizona, east to Dakota and Colorado. A most polymorphous species, and 

 the oldest name not a good one. Bracts, as in other species, varying from red to yellow or 

 white. 



C. miniata, Dougl. A foot or two high, mostly simple and strict, glabrous or nearly so 

 except the inflorescence : leaves lanceolate or linear, or the .upper ovate-lanceolate, acute, 

 entire (rarely laciniate-3-cleft) : spike dense and short: bracts from lanceolate to oval, 

 mostly bright red, rarely whitish, seldom lobed : calyx-lobes lanceolate, acutely 2-cleft : 

 corolla over an inch long; the galea exserted, linear, longer than the tube ; very short lip 

 protuberant and callous, as deep as long, with ovate short teeth involute. Hook. Fl. ii. 10(3 ; 

 Benth. 1. c. ; Gray, Bot. Calif, i. 574. C. pallida, var. Unalaschcnsis, Cham. & Schlecht. 

 1. c., partly. C. pallida, var. miniata, Gray in Am. Jour. Sci. I.e. 337. Alaska to Sas- 

 katchewan and southward along the higher mountains through Colorado, Utah and Cali- 

 fornia. 



= Galea decidedly shorter than the tube of the corolla and not over twice or thrice the length of 

 the lip. 



C. pallida, Kunth. A foot or so high, strict, commonly villous with weak cobwebby 

 hairs, at least the dense and short leafy-bracted spike, or below glabrous, not glandular or 

 viscid : leaves membranaceous, mainly entire ; the lower linear ; upper lanceolate or ovate- 

 lanceolate: bracts oval or obovate, partly white or yellowish, equalling the (half to inch 

 long) corolla : calyx cleft to or below the middle and again more or less 2-cleft ; the lobes 

 oblong or lanceolate : galea 2 to 4 lines long, barely twice the length of the lip, its base 

 not exserted from the calyx. Syn. PI. vEquin. ii. 100 : Benth. 1. c. ; Gray, Bot. Calif, i. 

 575. C. Siliirica, Lindl. Bot. Reg. under 925. Bartsia pal/Ida, L. Spec. ii. 002. Subarctic 

 N. W. coast and islands, Chamisso, &c. (Siberia.) Passes into 



Var. septeiltrionalis, Gray. A span to 2 feet high, sometimes almost glabrous : 

 bracts greenish-white, varying to yellowish, purple, or red : lip smaller, from half to hardly 

 a third the length of the galea. Bot. Calif. I.e. C. septentrional is, Lindl. Bot. Reg. 

 t. 925 ; Benth. 1. c. C. pallida, Hook. Kew Jour. Bot. v. 258. C. pallida, var. Unulaschensis, 

 latifolia, Cham. & Schlecht. 1. c. C. acuminata, Spreng. 1. c. Bartsia acuminata, Pursh. Fl. 

 ii. 429. Labrador, alpine summits of White Mountains and Green Mountains of New Eng- 

 land, and north shore of Lake Superior, to the Rocky mountains of Colorado and Utah, 

 and north-westward to Alaska, Aleutian Islands, &c. Some larger forms appear to pass 

 into C. niitiiata. 



Var. OCcidentalis, Gray. Dwarf and narrow-leaved form, 2 to 6 inches high: 

 bracts comparatively broad, mostly incised or cleft, the tips and flowers whitish : lip 

 about half the length of the rather broad galea. Bot. Calif. 1. c. C. occidenta/is, Torr. in 

 Ann. Lye. N. Y. ii. 230; Benth. 1. c. High alpine region of the Rocky Mountains, Colo- 

 rado, and Sierra Nevada, California. 



Var. Haydeni. More slender, 3 to 5 inches high : linear leaves sometimes with one or 

 two slender-subulate lobes : bracts merely ciliate-pubescent, laciniately 3-5-cleft into linear 

 lobes, bright crimson: lip not half the length of the galea. Alpine region of the Sierra 

 Blanca, S. Colorado, Hayden, Hooker, & Gray. Seemingly very distinct from C. pallida, 

 but connected through the preceding variety. 



C. viscidula. A span high, tufted, pubescent with very short stiff mostly glandular- 

 tipped hairs and somewhat viscid, only the dense naked spike with some short villous 

 hairs : stems slender : leaves linear, attenuate, entire, or uppermost 3-cleft : bracts 3-5- 

 cleft, more or less dilated ; the upper rather shorter than the flowers, with reddish or whit- 

 ish lobes : calyx-segments shorter than the cylindraceous tube, 2-parted into linear-lanceo- 

 late lobes: corolla three-fourths inch long; galea hardly one-third the length of the tube, 

 twice the length of the lip ; lobes of the latter elongated-oblong, equal in length to the 

 ventricose obscurely 3-carinate but not callous lower portion. Nevada, in the E. Hum- 

 boldt Mountains, at 9,000 feet, Watson (part of no. 810). 



C. Lemmoni. A span or more high, pubescent, and the dense oblong spike somewhat, 

 hirsute-villous, not glandular : leaves narrowly linear, entire or 3-cleft ; uppermost more 

 dilated and cleft: bracts 3-cleft, the upper with reddish lobes and equalling the flowers: 

 calyx-segments as long as the tube, oblong, petaloid, emarginate or barely 2-cleft at apex : 

 corolla fully three-fourths inch long; galea oblong, about a quarter the length of tube, 

 hardly twice the length of the ventricose lip; lobes of the latter ovate, rather shorter than
