 leaves and bracts inctsely pinnatifid or toothed. 



9. C. mollis, Gray, 1. c. Barely a foot high, with numerous branches, villous- 

 hirsute : leaves oblong- linear ; the lower entire and. obtuse ; the upper and the 

 bracts with 2 to 4 pairs of laciniate obtuse teeth or lobes : flowers in short thickish

Salt-marshes of San Francisco Bay, at Mare Island and Vallejo, C. Wright, E. L. Greene. 

 Corolla three fourths of an inch long. Seeds somewhat reniform, with a loose and thick cellular- 

 reticulated coat. 



19. PEDICTJLARIS, Tourn. LOUSEWORT. 



Calyx 2 - 5-toothed, irregular. Corolla strongly bilabiate ; the upper lip (galea) 

 arched and laterally compressed, sometimes beaked ; the lower erect at base, 2-crested 

 above, 3-lobed. Stamens 4, enclosed in the upper lip : anthers transverse, equally 

 2-celled, all or in pairs closely approximate. Style filiform : stigma small, entire. 

 Capsule ovate or lanceolate, oblique, compressed, more or less loculicidal. Seeds 

 several or numerous, comparatively large, ovoid. Perennial herbs ; with alternate 

 or sometimes opposite or whorled leaves, these mostly pinnately divided or lobed, 

 the floral ones commonly reduced to bracts ; the flowers commonly spicate, some- 

 times racemose, of various colors. The leaves in ours all or mostly alternate. 



A genus of nearly 150 species, widely distributed, but chiefly in the northern hemisphere and 

 in cool temperate or arctic regions, more numerous from Oregon northward and in the Eocky 

 Mountains than in California, which, however, has two or three peculiar species. 



* Leaves undivided, merely serrate : flowers racemose : corolla beaked. 



1. P. racemosa, Dougl. Glabrous or nearly so : stems numerous in a cluster, 

 a foot or two high, very leafy : leaves lanceolate, with narrowed base more or less 

 petioled, closely and often doubly crenate-serrate ; the upper floral or bracts linear 

 and entire and shorter than the flowers, but the raceme leafy below : calyx split 

 down the front, 2-toothed posteriorly : corolla white or purplish, with tube hardly 

 exceeding the calyx ; the upper lip strongly incurving and tapering into a subulate 

 beak which touches the broad lower lip : anthers pointed at base. Hook. Fl. 

 ii. 108. 



Mountain woods, Sierra and Bear Valleys, Lemmon, Bolander. Also Utah and Colorado in the 

 higher mountains, and north to British Columbia. 



* * Leaves at least once pinnatifid. 



-f- Upper lip of the corolla tipped with a long and slender proboscis; its base ivith a 

 tooth on each side : anthers very blunt : stem and virgate spike strict, together from 

 a span to 2 feet high. 



2. P. Groenlandica, Eetz. Glabrous : leaves lanceolate in outline, pinnately 

 parted ; the divisions linear-lanceolate, sharply and sometimes incisely serrate: calyx 

 campanulate ; the 5 teeth short : corolla rose-colored, short, barely half the length 

 of the filiform deflexed and then ascending or recurved beak, this nearly half an 

 inch long. Fl. Dan. t. 1166, poor. P. incarnata, Eetz, Obs. iv. 27, t. 1. P. sur- 

 recta, Benth. in Hook. Fl. ii. 107, & Prodr. x. 566 ; the larger-flowered form, which 

 prevails. 



Higher parts of the Sierra Nevada from Placer Co. (Torrey) east to the Rocky Mountains, and 

 north to British Columbia, Labrador, and Greenland ? 



3. P. attollens. Gray. Glabrous below : the dense spike rather woolly : leaves 

 lanceolate or linear in outline, pinnately parted, with linear or somewhat oblong 

 divisions, some of the lowest leaves nearly bipinnatifid ; the upper scattered, gradu-
