1. Pedicularis canadensis L. Common lousewort. Fig. 704. 



Perennial, hairy; stems simple, closely clustered, to about 4 dm. high; leaves 

 scattered, the lowest pinnately parted, the others pinnatifid, all or nearly all

 commonly spreading, the lateral ones rounded and larger; anthers transverse, the 

 cells pointless; capsule lance-oblong-flattened, several-seeded, twice as long as 

 calyx. 



In open forests, on the edge of forests, on open seepage slopes and marshy 

 soils, also in clearings and prairies, in Okla. {Waterfall) and e. Tex., Mar. -May; 

 from Me. and Que. to Man., s. to Fla., Miss., La., Tex. and n. Mex. 



2. Pedicularis groenlandica Retz. Elephant's head. Fig. 705. 



Plant glabrous throughout; stems 3-7 dm. tall, exceeding the leaves that are 

 basal and on lower part of stem; leaves 10-15 cm. long and 2 cm. wide, with 

 12 to 15 pairs of pinnules (all cut to the narrowly margined midribs), each 

 linear-lanceolate and somewhat saliently and callosely serrate-dentate, the basal on 

 petioles usually shorter than the blades, the cauline short-petioled or sessile, the 

 upper much smaller; bracts of inflorescence shorter than the flowers, linear- 

 lanceolate, with a few pairs of slender lobes; pedicels 1-1.5 mm. long; calyx 4-5 

 mm. long, with 5 subulate entire lobes of which the uppermost is scarcely shorter 

 than the others, the calyx tube scarcely cleft ventrally; corolla 8-10 mm. long, 

 glabrous, bright-pink to red-purple, its tube straight, its upper lip arched and 

 decurved, dark-purple, terminating in a slender and side-curving dark-purple beak 

 4-8 mm. long, its lower lip deflexed-spreading, light mallow-purple, the middle 

 lobe somewhat the narrowest; anther cells acute; capsule 6-8 mm. long, dorsally 

 rounded and dehiscing throughout, ventrally less rounded and dehiscing distally; 

 seeds 3 mm. long. 



In wet mt. meadows, seepage banks about lakes and ponds, in swamps and 

 marshy areas, in N. M. (Taos Co.) and Ariz. (Apache Co.), June-Sept.; Greenl. 

 to Alas., s. in mts. to N.M., Ariz, and Calif. 



3. Pedicularis Parryi Gray. Fig. 704. 



Plant glabrous or the inflorescence slightly pubescent; stem strict, to about 

 4 dm. tall, very leafy at base but slightly so above; leaves linear-lanceolate in 

 outline, the lower ones 4-10 cm. long, deeply pinnately parted into numerous 

 linear-lanceolate acute pinnatifid divisions 4-6 mm. long and closely callous- 

 serrate; uppermost leaves reduced to narrow linear bracts; spike dense, elongate- 

 spiciform, 4-20 cm. long; calyx 5-toothed, the teeth entire; corolla 1-2 cm. long, 

 ochroleucous or more yellow; galea strongly falcate, with decurved subulate- 

 conical beak of about the length of the width of the galea. 



In wet mt. meadows, in and along boggy streams, N. M. (Rio Arriba. Colfax 

 and Mora cos.) and Ariz. (Apache, Greenlee and Coconino cos.), June-Oct.; 

 Wyo. to Mont., s. to N.M. and Ariz.
