Orthocarpus. SCROPHULARIACE.E. 579 



12. O. faucibarbatus, Gray. Nearly glabrous, or the bracts, &c., with some 

 short hirsute pubescence, rather stout, and the branches fewer : leaves rather coarser : 

 corolla apparently white and with smaller sacs ; the beard within less conspicuous ; 

 the straight upper lip barely tinged with purple : otherwise nearly as 0. erianthus. 



-Pacif. E. Rep. iv. 121 ; Watson, Bot. King Exp. 457. 



Moist grounds, around San Francisco Bay and northward to Mendocino Co., apparently not 

 rare. 



* * Anthers 1-celled; the lower cell mostly small and imperfect in the first two species: 

 seed with an outer loose and arilliform coarsely reticulated coat. 



-t- Lower lip of the corolla very broad; the sacs deeper (horizontally) than long, 

 ++ Comparatively small: narrow upper lip truncate at the tip : capsule oblong, obtuse. 



13. O. gracilis, Benth. Minutely pubescent, or below glabrous, branched from 

 the base ; the slender branches a span or more high : leaves 3-parted into linear- 

 tiliform divisions, or some of the lower nearly entire : upper bracts shorter than the 

 rather closely spicate flowers, the tips of their lobes purplish-tinged : corolla pubes- 

 cent, purplish ; its slender tube twice the length of the calyx ; lower lip decidedly 

 shorter than the upper ; its sacs small but deep, somewhat conical. 



California (near Monterey ? ), Douglas, Nuttall. We have only specimens from Douglas. 

 Corolla 7 lines long ; the upper lip 2 lines ; lower one a line deep. Seeds broadly oval, in a very 

 loose and lace-like arilliform coat. 



-n- -n- Sacs ample : upper lip subulate : capsule ovate : stem simple or few-branched : 

 spike thickish and commonly dense, at least above. 



14. O. campestris, Benth. Glabrous or nearly so below, above (the calyx and 

 base of bracts) hirsute or hispid, 2 to 4 inches high : leaves and bracts narrow-linear 

 and entire, rarely with a lobe or two : calyx-lobes lanceolate, often united in pairs : 

 corolla white ; the erect and scarious teeth of the lower lip slender and rather 

 conspicuous. PI. Hartw. 329. 



Fields in the valley of the Sacramento, Hartweg. Plumas Co., Mrs, Pulsifcr Ames. Corolla 

 about three fourths oi' an inch long : lower lip 2 lines deep. 



15. O. lithospermoides, Benth. Hirsute above, pubescent below, about a 

 foot high, strict and simple or with some erect branches, very leafy : leaves lance- 

 olate or lanceolate-linear and all but the lower with few or several slender lobes ; 

 the floral with a dilated base and somewhat palmate lobes almost equalling 

 the crowded flowers : calyx-lobes linear : corolla cream-color, " often turning pale 

 rose-color " ; the sacs very ventricose (fully 3 lines wide) ; the teeth short and incon- 

 spicuous. 



Hillsides, and moist meadows ; common through the western part of the State from San Fran- 

 cisco Bay and the Sacramento northward. Corolla an inch long or rather less. 



-f- -t- Lower Up of the corolla less ample, surpassed by the subulate upper one; the sacs 

 not deeper than long: hirsute, strict and simple, or the larger plants branching, with 

 leaves and lobes linear and mostly attenuated : spikes leafy : calyx-lobes slender. 



16. O. lacerus, Benth. A span to a foot high, rather soft-hirsute and above 

 viscid : leaves mostly pinnately parted or the upper floral palmately 3 - 7-cleft into 

 long and narrow divisions or lobes : leafy spikes at first dense, at length loose : 

 calyx-lobes shorter than the tube : corolla yellow, its sacs about as deep as long. 

 PI. Hartw. 329. 0. hispidus, Watson, Bot. King Exp. 230, in part, &c. 



Open grounds, from the valley of the Sacramento (Hartwc.rj) and through the Sierra Nevada, 

 where it abounds from Mariposa Co. to Sierra Valley. Corolla two thirds or half an inch long ; 

 the tube little or considerably longer than the calyx. Related on one hand to 0. Jithospermoides 

 in its larger forms, in the smaller ones to 0. hispidus, with which it has been confounded.
