 3-5 dm. high; leaves narrowly lance-linear to almost filiform, usually entire; 

 bracts 3-cleft to near the base into linear-lanceolate attenuate divisions; calyx 

 about 6 mm. long; its lobes linear-lanceolate, acuminate; corolla about 15 mm. 

 long; galea about 6 mm. long; lip 5 mm. long, only slightly gibbous. Mountains

21. TRIPHYSARIA (Benth.) Rydb. PELICAN FLOWER, JOHNNY-TUCK. 



Annual caulescent herbs. Leaves alternate, often pectinate, or else entire, 

 those subtending the flowers usually colored. Flowers perfect, in terminal 

 leafy spikes. Calyx deeply 4-cleft. Corolla irregular, 2-lipped; upper lip erect, 

 straight, narrow, much shorter than the lower, which is 3-lobed and strongly 

 3-saccate. Stamens 4, didynamous, ascending under the upper corolla-lobe; 

 anther-sacs solitary or two and then dissimilar in the manner of the two pre- 

 ceding genera. Stigma capitate or sometimes 2-lobed. Capsule oblong, locu- 

 licidal; seeds many, reticulate. 



1. T.hispida (Benth.) Rydb. Stem 2-3 dm. high, soft-hirsute, strict, simple; 

 leaves with linear-lanceolate, attenuate divisions, or the lower entire, soft- 

 hirsute; spike leafy; bracts similar to the leaves; calyx-lobes subulate; corolla 

 white, 15-18 mm. long, viscid-puberulent; lip saccate, 2-3 mm. deep; galea 

 subulate. Low ground: Wash. Ida. Nev. n Calif. Submont. My-Jl. 



22. ADENOSTEGIA Benth. 



Branching annuals. Leaves narrow, alternate. Flowers perfect, in leafy 

 spikes at the ends of the branches. Calyx cleft to the base on the sides and 

 therefore 2-leaved, or sometimes 1-leaved by the want of the lower division. 

 Corolla tubular, with a funnelform throat, slightly 2-lipped; the upper lip narrow, 

 entire; the lower round, slightly 3-toothed or entire. Stamens 4, didynamous, 

 or sometimes the shorter pair wanting. Styles wholly united, with an inflexed 

 apex; stigma entire. Capsule compressed, loculicidal. Seeds few. [Cordy- 

 lanthus Nutt.j
