1. Pedicularis lanceolata Mx. Lanceleaf Lousewort. 



A stout, erect, usually simple perennial, 1-3 ft. high, glabrous or 

 nearly so. Leaves mostly opposite, lanceolate, or linear-lanceolate, 2-5

 reduced to bracts. Flowers in short, terminal, dome-shaped spikes; 

 calyx cleft on the lower side, with several tooth-like lobes on the upper 

 side; corolla pale greenish-yellow, the upper lip tinged with brown or 

 brownish-purple, 's-1 in. long. Inflorescence decidedly elongating in

Erect herbs, parasitic on the roots of other plants, with 

 alternate leaves and usually brightly-colored, inflorescence 

 bracts. Flowers in spikes or racemes. Calyx laterally com-

1. Castilleja coccinea (L.) Spreng. Scarlet Painted-cup. 



Annual or commonly biennial, villous-pubescent, rather slender 

 plant, 1-2 ft. high. Stem leaves prominently parallel-veined, divided 

 into 3-5 linear, obtusish segments, sessile; the basal leaves in a rosette, 

 parallel- veined or some at least, with two prominent side ribs from the 

 base, entire. Inflorescence bracts 3-5 cleft, the lower green, the upper 

 ones orange-scarlet, very conspicuous. Corolla ^-1 in. long, greenish-
