320 FIGWOKT FAMILY. 



10. ANTIRRHINUM. No spur, but a sac 9r gibbosity at the base of the personate corolla 



(Lessons, Fig. 257) ; otherwise like 9. 



1 1 Neither spur nor sac at base of the corolla, nor a projecting palate in the throat, 

 nor with the upper lip laterally compressed or folded and narrow and arched. 



o Stamens with anthers 4, and no rudiment of the fifth ; peduncles \-flowered. 

 x Plant climbing. 



11. MAURANDIA, including LOPHOSPEUMUM. Herbs with alternate or partly oppo- 



site leaves, and solitary long-peduncled flowers in their axils, climbing by their coil- 

 ing leafstalks and flowerstalks. Calyx 5-parted, foliaceous. Corolla open-mouthed, 

 between bell-shaped and inflated-tubular, with 2 plaits or hairy lines running down 

 the tube within, the border obscurely 2-'ipped or oblique, but the 5 spreading round- 

 ish lobes nearly similar, the upper ones outermost in the bud. Pod as in 10. 



x x Plant not climbing (erect or trailing). 

 + Flowers (hanging) in a terminal shoioy raceme or spike. 



12. DIGITALIS. Herbs with erect simple stem and alternate leaves. Calyx 5-parted, 



foliaceous, the upper sepal smallest. Corolla declining, with a long more or less 

 inflated tube and a short scarcely spreading border, distinctly or indistinctly lobed, 

 the lower lobe or side longest, the lateral ones outermost in the bud. Pod 2-valved, 

 many-seeded. 



+ + Flowers axillary, and generally solitary. 



Upper lobes (or lips) of corolla covering the lower ones in the bud (except sometimes 



in No. 13 and perhaps in No. 17.) 



Calyx prismatic. 



13. MIMULTJS. Leaves opposite, with single flowers in the axils of the upper ones. Calyx 



with 5 projecting angles, 5-toothed. Corolla tubular or funnel-form, 2-lipped, the 

 upper lip of 2 rounded and recurved lobes, the lower of 3 rounded spreading lobes. 

 Stamens included. Stigma of 2 flat lips. Pod 2-valved, many-seeded. 



14. TORENIA. Trailing herbs, with opposite leaves. Calyx with sharp angles, 2-lipped 



at summit, the lips 2-toothed and 3-toothed. Corolla short-funnel-shaped or tubular 

 with inflated throat, 4-lobed, the upper lobe (sometimes slightly notched) outermost 

 in the bud. Filaments arched and their anthers brought together in pairs under the 

 upper lobe, the longer pair almost equaling the upper lobe and bearing a short naked 

 branch or appendage at base ; the shorter pair simple and included. Stigma 2-lipped. 

 Pod many-seeded. ^ Calyx not prismatic. 



15. CONOBEA. Low branching herbs with opposite leaves and small whitish flowers. 



Calyx 5-parted, equal. Upper lip of short corolla 3-lobed and the lower 3-parted. 

 Stigma 2-lobed. 



16. HERPESTIS. Low rather succulent herbs with opposite leaves. Calyx 5-parted, but 



the upper division broader. Upper lip of the short corolla entire or notched or 2- 

 cleft, the lower 3-lobed ; or rarely the limb nearly equally 5-lobed. Style dilated or 

 2-lobed at the top. 



17. LIMOSELLA. Creeping fleshy plants, with clustered entire leaves. Calyx 5-toothed 



and bell-shaped. Corolla short and small, open-bell-form, nearly regular and 5-cleft. 

 Style short and club-shaped. 



Lower or lateral lobes of corolla covering the upper ones in the bud. 



18. GERARDIA. Herbs with branching steins, opposite or some alternate leaves, and 



above with single flowers in their axils or those of the bracts. Calyx 5-toothed or 

 5-cleft. Corolla inflated bell-shaped or tubular funnel-form, with an oblique or rather 

 unequal border, the 5 lobes somewhat equal, the lower and lateral ones outside in 

 the bud. Two pairs of stamens of quite unequal length. (Lessons, Fig. 263.) Pod 

 globular or ovate, pointed, 2-valved, many-seeded. 



19. 8EYMERIA. Herbs, like 18 ; but corolla with a short and broad bell-shaped tube, not 



longer than the 5 ovate or oblong nearly equal spreading lobes ; and the stamens 

 almost equal, their anthers blunt at base.
