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

 through the same range as the preceding. 



++ ++ Upper lip of the corolla considerably shorter than the tube, barely twice or thrice 

 the length of the comparatively conspicuous lower lij). 



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

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

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

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

 "white or yellowish, e(i|ualling tho flowers (these commonly an inch long) : lower 

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

 Lindl. Baitsia pallida, Linn. This is Siberian and Arctic N. W. American. 



Var. septentrionalis. Commoidy 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 loss large, from one third to half tho length 

 of the upper. — C. septentrionalis, Lindl. Bot. .I\og. t. 925 (1825). C. acuminata, 

 Bpreng. 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 \ipper canline as well as the sparingly colored (pale) bracts often 3-cleft : corolla 

 a third to half an inch long ; its lower lip about half tlio longth of tho upper. C. 

 occidentalis, Torr. in Ann. Lye. N. Y. ii. 230. 



Even the var. septentrionalis, which abounds on the liigher moinitnins north and cast of Cali- 

 fornia, and extends across the continent liigh northward to Labrador, lias not been met with 

 in the State. Var. occidentalis (belonging to the higlier alpine region of the Rocky Mountains), 

 on the higher parts of the Sierra Nevada, from Tulare Co. to Sierra Co., Brewer, Bolander,

17. ORTHOCARPUS, Nutt. 

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

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

 lip (galea) little or not at all longer than tho lower, like that of Casiilleia 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 

 tho later onos are conspicuously dillVrent. 



§ 1. Lower lip of the corolla simply or someichat triply saccate, and hearing 3 

 conspicuous mostly erect teeth or lobes; the np])er lip broadifh or narrow: 

 stigma capitate: anthers all 2-celled : sced-cont very loose, cellnlarfavose and 

 arilliform : bracts tt>i(k more or less of colored tips. — Castilleioides, 

 Gray. 



Closely connof'tfl with nnstillrin, through C. hrri/lnrn, the porpiniinl specii'q truly nmbiguous

 equals the short upper one. hi extending I^cnthain's section OncorrlnixrhuR (so called because it 

 inchi(les Lehmann s genus Oncorrhynchns), the sectional nainn is chnngrd on account of its inap- 

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

 other, except in the anomalous 0. purpurascens.
