 Herbs, with alternate opposite or rarely vcrlicillate, pinnately lolied cleft or pinnatifirl 

 leaves, and yellow red purple or white flowers, iu terminal spikes orsjnke-likc racemes. Calyx 

 tubular, clefl on the lower side or sometimes also on tlie upper, or 2-5-toothed. Corolla 

 strongly 2-lipped, the tube cylindric, the upper lip (galea) laterally compressed, concave or 

 conduplicate, sometimes beaked; lower lip erect or ascending, 3-lobed, the lobes spreading 

 or reflexed, the middle one the smallest. Stamens 4, didynamous, ascending within the 

 upper lip of the corolla; anthers appro.ximate in pairs, their sacs transverse, equal, parallel,

 many-seeded, loculicidally dehiscent. Seeds reticulate, pitted, striate or ribbed. [Latin, 

 pertaining to lice, long supposed to breed lice in sheep that feed on these plants.] 



About 125 species, mostly natives of the northern hemisphere. In addition to the followins:, 

 some 25 others inhabit the western parts of North America. Mostly known as Lousewort; a few 

 red-flowered species are called Red Rattle.

Perennial, glabrous; stem simple, erect, 1°-!%" 

 high. Leaves alternate, lanceolate in outline, acute 

 or acuminate, pinnately parted or the lower pinnately 

 divided into lanceolate acute creuulate or incised 

 segments, the upper sessile, the lower sleuder-pcti- 

 oled, 2'-6' long; spike i'-5' long, very dense; cal_\ x 

 5-toothed, nearly as longas the corolla-tube, the teeth 

 short, acutish; corolla red or purple, the galea pro- 

 duced into a filiform beak 6"-S" long, which is de- 

 curved against the lower lip and upwardly recurved 

 beyond it; body of the corolla 2^2 "-3" long; capsule 

 obliquely ovate, about 3" long. 



In wet soil, Labrador, Greenland and Hudson Bay to 

 the Northwest Territorj' and British Columbia, south in 

 the Rocky Mountains to New Mexico, and in the Sierra 

 Nevada to California. Summer. 



2. Pedicularis Lapponica L,. Lapland 



Pedicularis. (Fig. 3331.) 



Pedicularis Lapponica L. Sp. PI. 6og. 1753. 



Perennial, puberuleut; stems simple, or sparingly 

 branched, leafy, 4'-S' high. Leaves sessile, or very 

 short-petioled, alternate or the lowest opposite, lanceo-

 calj-x cleft on the lower side, 2-toothed on the upper; 

 galea erect, arched, tipped by an abruptly spreading or 

 recurved conic beak about I'-'long. 



In open places, Labrador and Greenland to the Arctic 

 Sea. Also in .\rctic Europe and Asia. Summer. 



Pedicularis pedicellata Bunge, ati Alaskan species is re- 

 corded by Bunge from Labrador. It is distinguished from 

 the above by its scapose stem, deeply pinnatifid leaves and 

 pedicellate lower flowers. We have not seeu specimens 

 from the eastern side of the continent.
