shorter than the flowers : corolla more than an inch long, narrow ; the linear-lan- 

 ceolate upper lip conspicuously long and exserted ; the lower very protuberant, as 

 deep as long, callous and mammoslbrm, with the ovate short teeth involute. — 

 Hook. Fl. ii. 106. C. pallida, var. miniata, Gray in Amer. Jour. Sci. 1. c. 



In the Siena Nevada and other mountainous districts, extending northward and eastward 

 through the same range as the preceding. 



^-i- +-i- Uiyper Up of the corolla considerably shorter than the tube, barely twice or thrice 

 the lengtli of the comparatively conspicuous lower lip. 



8. C. pallida, Kunth. A foot or so high, above commonly .villous with long 

 and weak cobwebby hairs, especially the dense leafy-bracted spike : leaves all or 

 mainly entire, membranaceous ; the lower linear ; the upper from narrowly to ovate- 

 lanceolate ; the floral or bracts often sparingly laciniate or cleft, colored usually with 

 white or yellowish, equalling the flowers (these commonly an inch long) ■. lower 

 lip of the corolla only one 'third or half shorter than the upper. — C. Sibirica, 

 Lindl. Bart><ia pallida, Linn. This is Siberian and Arctic N. W. American. 



Var. septentrionaliS. Commonly less pubescent, often almost glabrous, a span 

 to two feet high : bracts not rarely tinged with purple : corolla two thirds to three 

 fourths of an inch long ; its lower lip less large, from one third to half tbe length 

 of the upper. — C. septentrional is, Lindl. Bot. Iteg. t. 92.5 (182.5). C. acuminata, 

 Spreng. Syst. ii. 775 (1825, Bartsia acuminata, Pursh, unless this be C. miniata, a 

 slender pale form of which comes from Sitka, &c.). 



Var. OCCidentalis. Barely a span high, tufted : leaves rather rigid, narrow ; 

 the upper cauHne as well as the sparingly colored (pale) bracts often 3-cleft : corolla 

 a third to half an inch long ; its lower lip about half the length of the upper. C. 

 occidentcdis, Torr. in Ann. Lye. i^. Y. ii. 230. 



Even the var. scptentrionalis, which abounds on the higher mountains north and east of Cali- 

 fornia, and extends across the continent high northward to Labrador, has not been met with 

 in the State. Var. occidentcdis (belonging to the higher alpine region of the Eocky Jlountains^

Calyx short-tubular or oblong-campanulate, 4-cleft, or sometimes cleft before and 

 behind, and the two lateral divisions 2-cleft or parted. Corolla tubular ; the upper 

 lip (galea) little or not at all longer than the lower, like that of Castilleia but 

 shorter, small in comparison with the inflated 1 - 3-saccate lower one. Stamens as 

 in Castilleia, or the lower and smaller anther-cell sometimes wanting. Style, cap- 

 sule, &c., similar. — Low annuals, with two exceptions (of the Californian region 

 and one South American), more or less resembling Castilleia in foliage and inflores- 

 cence, very nearly related to it through the first of the following species, although 

 the later ones are conspicuously different. 



§ 1. Loiver lip of the corolla simply or someiohat triply saccate, and bearing 3 



conspicuous mostly erect teeth or lobes; the dipper lip broadi^h or narrow: 



stigma capitate : anthers all %celled : seed-coat very loose, cellularfavose and 



arilliform : bracts with more or less of colored tips. — Castillkioides, 



Gray. 



Closely connects with Castilleia, through C. brcviflora, the perennial species truly ambiguons 



between the two genera, but retained here on account of the size of the lower lip, whi<-]i nearly 



equals the short upper one. In extending Bentham's section Oncorrhynchus (so called bciMusr it 



includes Lehmann's genus Oncorrhynchus), the sectional name is change(l on account of its ina]!- 



propriateness : for the galea is not hooked in the original South American species, nor in any 



other, exc^t in the anomalous 0. purpurascens.
