FIGWORT FAMILY 847 



Leaves lanceolate to oblong, at least the lower entire; inflorescence an elongated spike, the bracts uniform, 

 entire to pinnately lobed, nearly equaling to exceeding the corollas; calyx ample and spathe-like, enclos- 

 ing proximal portion of corolla. I- Hemistegia. 



Leaves or leaf-segments linear to filiform; inflorescence of head-like clusters (abbreviated spikes) of 1 to many 

 flowers, the immediate flowering bracts usually modified and calyx-like; calyx itself narrow, enclosing 

 the corolla (partially or wholly) only at base. II. Eucordylanthus.

Bracts usually with a pair of short distal lobes: corolla 18-20 mm. long, shorter than calyx, its throat 

 moderately inflated, the lower lobes and thin margin of upper lip purple; leaves dark green, soon 

 glabrescent except for ciliate margins; hairs filiform, some tipped with minute dark glands.

Corolla 13-15 mm. long, little inflated, the galea only slightly compressed sagittally. 



Calyx bidentate at apex; corolla purplish, its galea dorsally with reflexed hairs; bracts with shorter hairs 

 or even glabrescent; axillary fascicles not developed. 

 Bracts with spreading lobes, purple (at least distally), ciliate and on veins beneath somewhat 

 pubescent, some of the hairs gland-bearing; corolla-lobes longer than the throat. 



3. C. palmatus. 



Bracts with more ascending lobes, pubescent over entire surface to ciliately so or glabrescent, the 

 hairs not glandular; corolla-lobes with more conspicuous membranous margins and about 

 as long as the throat. 4. C. carnulosus. 



Calyx entire at apex; corolla cream-white, its galea dorsally with spreading hairs; bracts and leaves hir- 

 sute-hispid, the former with spreading lobes; axillary fascicles much developed. 



5. C. hispidus. 



Corolla yellowish, 17-18 mm. long, decidedly inflated, the galea strongly compressed sagittally, both lips 

 pubescent externally with spreading hairs; bracts villose-hirsute. 6. C. molhs. 



II. EUCORDYLANTHUS. 



Stamens 4, the filaments bearded (at least proximally) ; throat plus lips of corolla nearly as long as or usually 

 longer than the basal tube; calyx little, if at all, shorter than the flowering bract, its ap«x cleft less 

 than 2 mm. 

 Galea not or scarcely longer than the lower corolla-lip, usually pale or dull in color and pressed against 

 it, the throat and lower lip horizontally expanded. 

 Corolla 10-30 mm. long; flowering bracts with slender hairs. 



Anthers 2-celled; corolla somewhat pubescent, more than twice as long as wide, the distal margins 



of the lower lip thickened; spikes 1-15-flowered, the flowers with dorsal side uppermost; 



flowering bracts with fine hairs quite like those of other leaves of inflorescence. 



Flowering bracts with 1 to 3 pairs of pinnately disposed lobes; calyx cleft distally about 



1.5 mm.; spike either without special subtending leaves or with such palmately 5-lobed. 



A. KlNGIANI. 



Flowering bracts toothed to entire at apex; calyx distally bidentate (to 0.5 mm.) to entire; 

 spikes head-like, subtended by several special leaves (outer bracts). 



Throat of corolla pubescent within ventrally; outer bracts palmately 3-7-lobed. 



B. Ramosi. 



Throat of corolla glabrous or nearly so within ventrally; outer bracts 3-lobed or entire. 

 Inflorescences of dense head-like clusters, each 3-15-flowered and subtended by 

 several 3-lobed outer bracts; plants with glandless hairs. 



C. RiGiDi. 



Inflorescences of racemosely disposed small clusters, each 1-3-flowered and sub- 

 tended by one or a few simple or 3-lobed outer bracts; plants often with 

 gland-bearing hairs. D. Tenues. 



Anthers 1-celled; corolla wholly glabrous, less than or about twice as long as wide, the distal 

 margins of the lower lip thin; spikes 1-3-flowered, the flowers inverted so that the ventral 

 side is uppermost; flowering bracts setose-pilose. E. Neviniani. 



Corolla 8 mm. long; flowering bracts entire and pilose with stout yellowish glands that are slightly 

 higher than long, the plants otherwise glandless. F. Pringleani. 



Galea longer than and upcurved away from lower corolla-lip, throat open and the inverted corolla bright 

 purple; outer bracts of the single-flowered capitula 3-lobed; plants with glandular hairs. 



G. Laxiflori. 



Stamens 2, the filaments glabrous and the anthers 1-celled; throat plus lips of corolla shorter than the basal 

 tube; calyx much sbarter than the flowering bract, its apex cleft about 3 mm. H. Capitati. 



A. KlNGIANI. 

 Only species in Pacific states. 7. C. Helleri, 



B. Ramosi. 



Outer bracts equaling the length of the flowering bract, calyx, and corolla, these structures greenish or dull 



purplish; plants more widely and equally laxly branched. 8. C.ramosus. 



Outer bracts much shorter than the flowers; plants with more stiffly ascending branches. 



Inflorescence purplish, strongly contrasted in color with the whitened foliage; corolla purplish; outer bracts 

 5-7-lobed; leaves silvery green, the main cauline ones 2-2.5 cm. long; plants more virgate, the 

 branches shorter. 9. C. eremtcus. 



Inflorescence yellowish, only slightly contrasted in color with the foliage; corolla yellow; outer bracts 

 3-5-lobed; leaves yellowish green, the main cauline ones 1-1.5 cm. long; plants with widely_ ascending 

 branches. '0- C. bernardtnus. 



C. RiGIDI. 



Outer bracts, with their lobes, not or scarcely widened distally; spikes not or relatively softly setose-ciliate, the 

 flowers less densely crowded; plants more widely branched. 

 Corolla 13-16 mm. long, its lower lip externally sparsely pubescent, the flowers 3 to .'^ in a cluster; plants 

 finely pubescent, or the bracts glabrescent, the latter ciliate. 11. C. Ferrtstanus.
