 lower lip no wider than long; calyx-lobes serrate to entire; pinnae of leaf- 

 blades strongly lobed and the lobes again serrate; stem 1-3 dm. tall, with a 

 few small leaves or scape-like, the flowers in a terminal congested cluster or 

 sometimes with a few lower and smaller fascicles. V. Asplenifoliak. 



Corolla pale yellow or white, proximally purple-spotted, the galea decurved over and 

 enfolded by the lower lip, its elongated beak decurved over 180° from the 

 oorolla-tube and the lower lip wider than long; calyx-lobes entire; pinnae of 

 leaf -blades sirnply serrate-dentate to dentate-lobed; stem 3-6 dm. tall, the 

 leaves decreasing uniformly from base or the upper portion sometimes bare, 

 the flowers in an elongated spike-like raceme. VI. Contortae. 



Beak upcurved, much longer than the body of the abruptly decurved galea; corolla purple. 



VII. SURRECTAE. 



Segments of the simply pinnatifid leaf-blades crenate-serrulate; bracts abruptly differentiated, sessile, little 



longer than wide, truncate or cordate at base, the inflorescence short and dense (semi-capitate), 3-5 



cm. long; corolla yellow, its lips distally purple, the galea narrowed to a beak little longer than 



wide; anther-cells acute. VIII. Compactae. 



Calyx-lobes apparently 2, the uppermost being lost and the two laterals of each side having united throughout; 



leaf-blades serrate or doubly crenate, the teeth cutting less than one-third distance to midrib. 



Corolla purple, the truncate apex of the galea with 2 bristle-like teeth ventrally; calyx distally crenate or 

 crenulate, the tip of each side toward the dorsal margin; capsule abruptly acute; stem with longi- 

 tudinal lines of fine pubescence; leaf -blades doubly crenate, the margins usually white-callose. 



IX. Canadenses. 



Corolla white or purple-tinged, the galea with a slender incurved beak that nearly or quite touches the 

 lower lip; calyx distally entire, the acuminate tip of each side medianly or slightly dorsally placed; 

 capsule attenuate-acuminate; stem glabrous; leaf-blades serrate to creno-serrulate, the margins less 

 frequently callose. X. Racemosae. 



I. Centrantherae. 



Capsule nearly symmetrical, dehiscing both ventrally and dorsally; corolla 27-28 mm. long, glabrous, the dark 

 purple lower lip strongly contrasting with the pale (but purple-tipped) galea; leaf-blades pinnatifid, the 

 midrib broadly winged and the segments somewhat doubly crenate-dentate. 1. P. centranthera. 



Capsule decurved distally, only on the dorsal side rounded and dehiscent; corolla 21-23 mm. long, externally 

 finely villose over the lower lip, mostly yellow but with the apices of both lips purple; leaf-blades more 

 deeply and sharply cut, the midrib narrowly or proximally not winged. 2. P. semibarbata. 



II. Densiflorae. 



Only species. 3. P. densifiora. 



III. Bracteosae. 



Apex of galea beakless. 



Lobes of calyx distally filiform, glandular-pubescent, the free portions of the lateral lobes longer than 

 their united proximal portions. 



Corolla violet-carmine, 20 mm. long; glands on calyx-lobes large, blackish; bracts 15-20 mm. long, 



lanceolate with caudate tips, much exceeding the calyces. 4. P. atrosanguinea. 



Corolla purple or partly yellow; glands on calyx-lobes small, pale; bracts shorter. 



Corolla 13-16 mm. long, the lobes of the lower lip ciliate; bracts oval, with caudate tips. 



5. P. bract eosa. 



Corolla 18-20 mm. long, the lobes of the lower lip erosely ciliolate to eciliate; bracts lanceolate- 

 caudate. 6. P. paddoensis. 



Lobes of calyx lanceolate to linear, not or scarcely glandular. 



Calyx-lobes linear, the free distal longer than the united proximal portions of the lateral lobes. 



Inflorescence villose; free distal usually more than twice as long as the united proximal portions 

 of the lateral calyx-lobes. 



Galea in anthesis raised little above and usually enfolded by the lower lip; bracts lanceolate 

 or ovate-lanceolate, with caudate tips that are as long as or longer than their proximal 

 portions; leaf-blades with 6 to 8 pairs of relatively wide dentate segments; corolla 

 greenish yellow. 7. P. pachyrhiza. 



Galea in anthesis raised well above and not enfolded by the lower lip; bracts ovate, with 

 caudate tips shorter than their proximal portions; leaf-blades with 8 to 10 pairs of 

 narrow doubly and sharply toothed segments; corolla with galea purple and lower lip 

 yellow. 8. P. Thompsonxi. 



Inflorescence glabrous or nearly so; free distal less than twice as long as the united proximal 

 portions of the lateral calyx-lobes; corolla greenish yellow. 9. P. flavida. 



Calyx-lobes triangular-lanceolate, the free distal shorter than the united proximal portions of the 

 lateral lobes; corolla either wholly greenish yellow or with purple galea. 10. P. latifolia. 

 Apex of galea narrowed to a short acute beak; corolla citron-yellow. 11. P. Canbyi. 



IV. HiRSUTAE. 



Corolla yellow, its lower lip ascending or appressed; sepals and dentations of leaf -blades acute to acuminate; 

 cauline leaves several, not overpassed by the basal ones; stem 2.S— 4 dm. tall, the raceme becoming 5-10 

 cm. long. 12. P. rainierensis. 



Corolla purple, its lower lip deflexed-spreading; sepals and dentations of leaf-blades cuspidate; cauline leaves 

 1 or 2, much overpassed by the large basal ones; stem 1-1.5 dm. tall, the raceme onlv 2-4 cm. long. 



13. P. Dudleyi.
