tlie base, 1 or 2 ft. liigh, villous-hirsute and viscid; leaves oval, obtuse, half an inch or 

 more long, some above 3-5-lobed and red; calyx 2-cleft to the middle, the lobes entire or 

 emarginate, almost equaling the corolla; corolla 8 lines long, the short teeth of the lip 

 inflexed. 



3. C. parviflora, Bong. A span to 2 ft. high, villous-hirsute above; leaves variously 

 cleft into linear or lanceolate lobes, or sometimes the cauline are mainly entire and nar- 

 row; calyx lobes oblong and 2-cleft at the apex or to below the middle; corolla an inch or 

 less long; only the upper part of the narrow galea exserted — A variable species. As in 

 the preceding species, the bracts and calyx are usually colored red or crimson, but some- 

 times varying to yellow or even white. 



4. C. miniata, Dougl. Commonly 2 ft. high, strict, often slender; leaves lanceolate 

 or linear-lanceolate, almost always entire, the broad floral ones of the close spike some- 

 times incised or 3-cleft, usually bright red, rarely whitish; calyx lobes lanceolate, acutely 

 2-cleft; corolla over an inch long, exserted, exposing the short ovate teeth of the lip. 



5. C. foliolosa, Hook. & Am. Densely white-woolly, the matted hairs loosened with 

 age; many-stemmed from a woody base; leaves narrowly linear, an inch or less long, 

 crowded below and fascicled in the axils. 



10. ORTHOCARPUS, Nutt. 



Chiefly distinguished from Castilleia by the upper lip of the corolla (galea) which but 

 little, if at all, surpasses the usually more conspicuous and inflated 1-3-saccate lower 

 lip. 



§ 1. C.ASTiLLEioiDES, Gr. — Lower Up of the corolla simply or somewhat triply saccate, and 

 hearing 3 conspicuous teeth; the galea hroadish or narrow; stigma capitate; anthers all 

 2-celled; bracts with colored tips. 



* Filaments smooth; galea straight or nearly so, naked, narrow; the lip moderately 



ventricose; its teeth erect. 



1. O. attenuatus, Gr. Slender, strict, a span or two high, mostly simple; leaves 

 linear and attenuate, often with a pair of filiform lobes; spike slender; lower flowers 

 Bcattered; bracts with slender lobes barely white-tipped; corolla narrow, half an inch 

 long, white or whitish; narrow teeth of the purple-spotted lip nearly equaling the galea. 



2. O. densiflorus, Benth. Erect or diSusely branched from the base 6 to 12 inches 

 high; spike dense, many flowered, at length cylindrical, or lowest flowers rather distant; 

 bracts 3-cleft, about equaling the flowers, their linear lobes purple and white; corolla 

 from 8 to 12 lines long, the tips usually purplish, the teeth of the lip shorter than the 

 galea. 



3. O. castilleioides, Benth. At length difi'use and corymbosely branched ; leaves from 

 lanceolate to oblong, usually laciniate; the upper and the bracts cuneate-dilated and 

 incisely cleft, green or the obtuse tips w^hitish or yellowish; spikes dense, short and thick: 

 corolla nearly an inch long, dull white or purplish- tipped; lip ventricose-dilated.
