Orlhocarpus. SCROPHULARIACE.E. 575 



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 mammselbrm, with the ovate short teeth involute. 

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



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 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. Bartsia 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 the length 

 of the upper. C. septentrionalis, Lindl. Bot. Keg. t. 925 (1825). 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 cauline 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. 

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



Even the var. septentrionalis, 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. occidentalis (belonging to the higher alpine region of the Rocky Mountains), 

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

 Lemmon. 



17. ORTHOCABPUS, Nutt. 



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. Lower lip of the corolla simply or someivhat triply saccate, and bearing 3 

 conspicuous mostly erect teeth or lobes ; the upper lip broadish or narrow : 

 stigma capitate : anthers all 2-celled : seed-coat very loose, cellular-favose and 

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

 Gray. 



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

 between the two genera, but retained here on account of the size of the lower lip, which nearly 

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

 includes Lehmann's genus Oncorrhynchus), the sectional name is changed 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.
