Calyx -lobes rounded or wholly united laterally; galea dorsally puberulent; bracts linear 

 or oblong, 3-lobed; leaves linear to linear-lanceolate, cinereous-whitened by the 

 close glandless tomentum. XVI. Lanatae. 



Calyx cleft laterally more deeply than medianly, its lobes unequal, lanuginous, the upper pair 

 linear-lanceolate and acute or obtuse, the lower pair much larger (usually both wider and 

 longer) and broadly rounded; bracts green, against which contrast the yellow galeas of the 

 corollas. XVII. Plagiotomae. 



Sepals united much farther dorsally than ventrally; corolla 30—45 mm. long, its lower lip less than one- 

 fourth the length of galea; bracts distally scarlet-red, the inflorescence elongated and with relatively 

 isolated flowers. XVIII. Linariaefoliae. 



Plant annual; leaves and bracts lanceolate-attenuate, entire, the younger bracts distally scarlet; calyx cleft 

 evenly medianly more deeply than laterally; corolla yellow or reddish distally, the galea more than 4 times 

 the length of the rudimentary but projecting lower lip. XIX. Stenanthae.

Galea lanosepubescent dorsally, its membranous margins narrow; pouch of the lower corolla-lip scarcely inflated; 



bracts dull yellow to reddish. 1. C. arachnoidea. 



Galea puberulent or finely pubescent, its membranous margin at least one-third its width; pouch of lower corolla- 

 lip inflated; bracts dull yellow to usually russet or dull reddish. 

 Pouch of lower corolla-lip somewhat inflated, less abruptly contracted to the pale free lobes; galea obtuse 



to acute; capsule 7-9 mm. long; leaf-segments linear. 2. C. Payneae. 



Pouch of lower corolla-lip much inflated, very abruptly contracted to the yellow free lobes; galea attenuate; 



capsule S mm. long; leaf-segments filiform. 3. C. fiUfolia. 



II. PiLOSAE. 



Membranous margins of galea yellowish-translucent throughout, its dorsal surface pubescent with glandless 

 hairs; lips of corolla usually wholly exserted beyond calyx, the corolla yellowish, with the lower lip nearly 

 as long as the galea; bracts with usually 2 pairs of lobes; stems ascending to erect, both stems and 

 leaves hirsute-villose. 4. C. psittacina. 



Membranous margins of galea proximally or wholly purple; lips of corolla partially or only tardily exserted beyond 

 calyx, the corolla greenish. 



Bracts distally widely rounded, narrowly whitish-margined, with 1 pair of lateral lobes (or sometimes alsr 



a distal shorter pair); galea pubescent dorsally with glandless hairs; plants 2-4 dm. tall, erect, the 



stem, leaves, and bracts villose-hirsute. 5. C. pilosa. 



Bracts acute or acutish, or else narrowly rounded, distally or wholly yellowish or purple; plants 0.5-2.5 dm. 



tall, diffuse or ascending, the stems more finely villose-hirsute and the leaves and bracts pubescent. 



Galea hairy to pubescent dorsally with glandless or slightly gland tipped hairs, its membranous margins 



distally pale or white like the lobes of the lower corolla-lip; calyx nearly as long as the corolla, 



so that the corolla-lips are only partially, if at all, exserted; bracts light yellow to dull purplish, 



with 1 pair of lateral lobes (or sometimes also a distal shorter pair); plants 0.5-2.5 dm. tall. 



6. C. nana. 

 Galea minutely puberulent, its membranous margins and the lobes of the lower lip all purple; calyx 

 much shorter than the corolla, the lips of which are wholly exserted; bracts purple, with 2 full 

 pairs of lateral lobes; plants 0.2-1 dm. tall. 7. C.rubida. 



III. CiNEREAE. 

 Only species. 8. C. cinerea. 



IV. Pallescentes. 



Corolla 13-15 mm. long, the pouch of the lower lip only slightly inflated, puberulent to glabrescent. 



Hairs of stem and leaves minute, reflexed-incurved to -appressed; calyx much shorter than corolla (reaching 



to pouch of lower lip), its lobes lance-attenuate, 1-1.5 mm. long; stem 1.5-2.5 dm. tall, stiff and 



often branched. 9. C. oresbia. 



Hairs of stem and leaves spreading; calyx not or little shorter than corolla, its lobes ovate, 0.5-1 mm. long. 



Bracts and calyces yellowish; calyx -lobes shorter than wide, acutish to rounded; stems many^ 1-2.5 



dm. tall, densely white-villose. 10. C. villicaults. 



Bracts greenish to vinaceous-brown, against which contrast the yellow calyces; calyx-lobes as long as 

 wide, acute to obtuse or slightly rounded; stems few or solitary, 1-1.5 dm. tall, somewhat villose- 

 hirsute. 11. C. cryptantha. 

 Corolla 17-25 mm. long; calyx little shorter than corolla (usually reaching to lobes of lower lip), its lobes 

 short and triangular-ovate. 



Pouch of lower lip and the galea finely pubescent, the former dark green and somewhat inflated; leaf-blades 

 and -segments filiform-linear; stem 1-2 dm. tall, diffusely ascending-erect, the herbage with reflexed 

 hairs. 12. C. pallescens. 



Pouch of lower lip and the galea puberulent to nearly glabrate, the former paler and scarcely inflated; 

 leaf-blades wider; stem usually taller, the herbage pilose-pubescent with spreading hairs. 



Stem and leaves finely pubescent, the former mostly 3-6 dm. tall, the latter linear or linear-lanceolate 

 with mid-blade mostly 1-1.5 mm. wide; bracts relatively narrow and leaf-like, the mid-blade 

 3-4 mm. wide, acutish or acute, and usually with 2 pairs of narrowly linear lobes; pouch of 

 lower corolla-lip purplish. 13. C. cervina. 



Stem and leaves hirsute, the former mostly 1.5-3 dm. tall, the latter broadly linear with mid-blade 

 mostly 1.5-3.5 mm. wide; bracts relatively wide, the mid-blade 3.5-5 mm. wide, obtusish to 

 rounded, and usually with 2 pairs of linear or widely linear lobes; pouch of lower corolla-lip 

 pale yellowish green to slightly purplish. 14. C. Thotnpscnii. 



V. Chrysanthae, 



Bracts yellowish, rounded at apex, exceeding or about equaling the corollas; galea puberulent to finely pubescent 

 with glandless or finely gland-tipped hairs; leaves many, ascending, mostly with linear-attenuate lobes. 



15. C. Cusickii. 



Bracts evidently exceeded by the corollas (only slightly so in C. Ownbeyana) ; galea, if pubescent, with gland- 

 tipped hairs. 



Leaves oblong lanceolate, obtuse, usually with a pair of lobes; stem, and margins and ribs of leaves and 

 bracts, hirsute with stifily spreading yellow hairs and also with some gland-tipped ones; calvx-lobes 

 free laterally 2-3 mm. (Glanduliferae) 24. C. xanthotricha. 



Leaves linear-lanceolate to lanceolate, attenuate, entire or the upper sometimes with a pair of lobes; stem 

 and leaves with laxly spreading glandless white hairs (or these obscurely gland-tipped in C. Lem- 

 monii) ; calyx-lobes shorter.
