ally smaller and simpler ; the lobes sharply serrate : calyx unequally 5-toothed ; the 

 teeth almost as long as the tube : corolla purple ; the upper lip little exserted out of 

 the calyx, much shorter than the broad lower one, and only about half the length 

 of its abrupt upturned or retrocurved filiform beak, this 2 or 3 lines long. — Proc. 

 Am. Acad. vii. 384. 



Moist meadows in the Sierra Nevada at 5,000 to 10,000 feet, from Mariposa to Placer Co., 

 Bridges, Brewer, Bolandcr, Torrcy. 



+- +- Upper lip of the corolla blunt and beakless : radical leaves ample, nearly equal- 

 ling or exceeding the spike or dense raceme. 



i. P. densiflora, Benth. Pubescent when young, or nearly glabrous, stout, a 

 span to a foot or more high : leaves oblong-lanceolate or broader in general outline, 

 ^v twice pinnatifid or piunately parted, and the divisions irregularly and sharply in- 

 cised and toothed ; the upper simpler and reduced to foliaceous bracts of the dense, 

 or in age more lengthened and looser spike or raceme : calyx-teeth 5, lanceolate or 

 subulate : corolla red or scarlet, straight and narrow, slightly clavate, an inch or more 

 long ; the lower lip very small, inconspicuous, only a quarter of the length of the 

 upper : anther-cells with tapering or acute base. — P. densiflora & P. attenuata, 

 Benth. in DC. 1. c. 574. 



Common throughout the western and middle portions of the State. Spike at first 2 or 3 inches, 

 in age often a foot or more in length : pedicels shorter than the calyx, sometimes very short. 

 Tube of the corolla either little or considerably exserted. 



5. P. semibarbata, Gray. Somewhat pubescent, or at length glabrate, almost 

 stomless : leaves crowded next the ground, slender-petioled, much exceeding the 

 short and nearly sessile spikes, twice piunately parted into small and short mostly 

 few-toothed or incised lobes : calyx unequally 5-toothed : corolla yellowish, exter- 

 nally pubescent, two thirds of an inch long, moderately enlarging upward, straight ; 

 the short obtuse upper lip a little incurved, slightly longer than the almost erect 

 lower one : the two longer lilaments villous above the middle ; the others nearly 

 naked : anther-cells abruptly pointed at the base. — Proc. Am. Acad. vii. 385. 



Open woods through the Sierra Nevada, at 5,000 to 10,000 feet, from Mariposa to Placer Co. 

 (Brewer, Bolandcr, Gray) ; also found near Carson City by Anderson. 



P. CENTRANTiiF.r.A, Gray in Bot. Mex. Bound. 120, is a somewhat similar, but more peculiar, 

 nearly stemless species, with once pinnatifid leaves, longer and purple corolla, and awned anthers. 

 It was discovered in New Mexico, but has recently been detected iu the southwestern part of 

 Utah, so that it may reach the borders of California, 



Order LXIX. OROBANCHACE^l. 



Root-parasitic herbs, destitute of foliage and green color, with irregular chiefly 



bilabiate corolla, didynamous stamens, and one-celled ovary and capsule with two or 



more parietal many-seeded placenta;, — by the latter character only distinguished 



from Scrophidariacew. — Seeds very small and numerous, anatropous, with a minute 



embryo at the base of transparent albumen. Calyx and corolla persistent, hypogy- 



nous. Stamens on the tul ii ■ of the corolla: anthers 2-celled. Style long: stigma 



2-lobed or nearly entire. Capsule 2-valved : each valve bearing one placenta or a 



pair. Dry or fleshy scales, in place of leaves, alternate. 



A small order mainl] of the northern temperate zone, of 1] genera and about ISO species, all 

 except a dozen belonging to the Old World, only two genera represented in or Dear California. 



1. Aphyllon. Stamens included: cells of the anthers pointed at base. Calyx 5-cleft 



2, Boschniakia. Stai ruded: anther-cells closely parallel and blunt at base. Calyx 



truncate posteriorly, the teeth anterior aud lateral.
