4. Pedicularis Grayi A. Nels. 



Stems 4-10 dm. tall, fistulose, glabrous or pubescent above and in the inflores- 

 cence; leaves 2-6 dm. long, basal and cauline, glabrous or somewhat pubescent 

 when young, pinnately divided to the midrib with the segments pinnatifid into 

 serrate or incised lobes; inflorescence 15-40 cm. long, spicate, many-flowered; 

 bracts linear from an ovate-lanceolate base, the lower ones pinnatifid and often 

 longer than the flowers; calyx 1-1.5 cm. long, with 5 linear-lanceolate lobes; 

 corolla 2.5-3 cm. long, sordid-yellow or sometimes streaked with red; galea 9-15 

 mm. long, curving downward and cucullate, not at all beaked but with 2 lateral 

 teeth just below apex. 



In damp woods, marshes and wet meadows along streams, in N.M. (widespread 

 in mts.) and Ariz. (Apache, Greenlee, Graham and Cochise cos.), June-Sept.; 

 also Wyo. 



20. Castilleja L.f. Indian Paintbrush. Painted-cup 



Perennial or annual herbs, sometimes woody at the base; leaves alternate, 

 entire or pinnately lobed; flowers in bracteate spikes; bracts prominent, usually 

 more conspicuously colored than the flowers; calyx tubular, terminating in 4 or 

 (if wholly united laterally) 2 lobes; corolla extremely zygomorphic, with a long 

 narrow galeate (hooded) upper lip and a shorter often vestigial lower lip, the 

 tube long and narrow; stamens 4, didynamous, each pair of anther sacs unequally 

 placed; capsule ovoid, bilocular, loculicidal; seeds numerous, the testa loose 

 and alveolately reticulate. 



More than 150 species, concentrated in western North America, Mexico and 

 Central America; 1 species in the West Indies, about 5 species in South America 

 and about 10 species in Eurasia. The common name "Indian blanket" is sometimes 

 loosely applied to this genus but that name should be reserved for Gaillardia of 

 the Compositae.
