Corolla 17-21 mm. long, its lower lip externally pubescent; plants softly pubescent throughout. 



Plants 3-6 dm. tall, diffusely and very widely branched; flowers 4 to 6 in a cluster, each corolla 20-21 

 mm. long; bracts finely pubescent, but nearly eciliale. 12. C. littoralis. 



Plants 4—12 dm. tall, with many ascending-spreading branches; flowers S to 10 in a cluster, each 

 corolla 17-21 mm. long; bracts setosely ciliate and pilose. 13. C. platycephalus. 



Outer bracts, and usually their lobes, clearly widened distally; spikes more harshly setose-pilose; plants with 

 ascending branches. 



Throat of corolla longer than wide, hardly distinguishable from tube; outer bracts with linear-oblanceolate 

 plane bodies, their width little (less than twice) or not exceeded by the spreading setae, the bracts 

 green to apex; corolla 12-14 mm. long. 



Plant laxly branched, several or many of the lateral branches exceeding the central stem; outer 

 bracts setose-hairy as well as ciliate, less obviously widened distally; flowers 3 to 6 in a loose 

 head, the corolla presumably dull yellowish. 14. C.rigidus. 



Plant more strictly branched, the lateral branches stricter and more erect, only the uppermost some- 

 times exceeding the central stem; outer bracts setose-ciliate, but slightly or not setose other- 

 wise; flowers 5-1 S in a compact head, the corolla light yellow, proximally dark brown within 

 throat. IS. C. compactus. 



Throat of corolla wider than long, strongly contrasted with tube; outer bracts with filiform-oblanceolate 

 b9dies, their width much (at least twice) exceeded by the spreading setae, the bracts with blackish 

 violet callose tips; corolla 14-16 mm. long, white, with dull purple wide antero-lateral lines. 



1 6. C. filif alius. 



D. Tenues. 



Outer bracts 3-lobed, the segments with enlarged tips. 



Plants diffusely spreading, the slender stems extensively procumbent; corolla 14—15 mm. long, its galea 



relatively pubescent distally; outer bracts with long spreading lobes. 17. C. nidularius. 



Plants erect, with many ascending branches; corolla with galea more finely pubescent. 



Flower-clusters brownish or purplish, hirsute; corolla with relatively dark galea; plants more 

 glandular. 



Lobes of outer bracts linear, flat, often relatively distally placed; corolla 15-18 mm. long. 



18. C. Hansenii. 

 Lobes of outer bracts narrowly linear or filiform, often involute, more proximally placed; corolla 

 13-16 mm. long. 19. C. viscidus. 



Flower-clusters light yellow-green, finely pubescent (the bracts ciliate); corolla with galea white; plants 

 finely pubescent, the hairs on stem beneath inflorescence gland-tipped, but elsewhere glabrous. 



20. C. pallescens. 

 Outer bracts entire, or angulate-dilated at apex. 



Inflorescence hirsute, the ciliation of the bracts relatively long; leaves linear, usually flat; stem pubescent 

 to hirsute over entire surface. 



Tips of outer bracts enlarged, usually angulate (to rudimentary bases of one or both lateral lobes). 

 Plant hirsute with slender glandless hairs that much exceed the short gland-tipped ones; main 



cauline leaves widely linear; branches strongly ascending. 21. C. pilosus. 



Plant canescent-pubescent with fine glandless hairs, but with gland-bearing hairs on stems below 

 inflorescences; main cauline leaves linear or narrowly linear; branches widely ascending- 

 spreading, diffuse. 22. C. diffusus. 

 Tips of outer bracts not or scarcely enlarged, not angulate though often callose; plant pubescent, 

 glandularly so above or throughout. 23. C. Bolanderi. 



Inflorescence merely pubescent, the bracts finely ciliate; leaves narrowly linear or filiform, mostly involute; 

 stem glabrous, or bifariously minutely pubescent. 



Tips of outer bracts enlarged, often essentially angulate-lobed ; corolla pale or white, with conspicuous 

 dark maroon-purple streaks; plants diffusely branched, the flowers solitary. 



24. C. brunneus. 



Tips of outer bracts not or scarcely enlarged, not angular nor strongly callose; corolla greenish 

 yellow, the galea wholly brown, the throat laterally purple-brown, but with less conspicuous 

 or no dark lines; plants with many ascending branches, the flowers in clusters of 1-3.

Plant 2-4 dm. tall, lax and somewhat decumbent, loosely much-branched, the herbage 

 pubescent with spreading filiform hairs, some of which bear small dark glands. Leaves and 

 bracts glaucous-green, the former oblong-lanceolate, the latter oblong, usually with a pair of 

 short sharp teeth near apex, foliaceous ; calyx 20-22 mm. long, oblong-lanceolate, enclosing 

 much of the corolla-throat, distally with sharp teeth less than 0.5 mm. long; corolla 18-20 mm. 

 long, its galea concave-rounded, finely pubescent dorsally, scarcely decurved at apex, and with 

 wide purplish thin margins, its lower lip with pilose-pubescent moderately inflated pouch and 

 minute glabrous rounded lobes; stamens 4, the slender upper filaments with slightly smaller 

 anthers, the lower thicker and longer, with fused anthers ; capsule 7-9 mm. long.
