tube, not longer than the 5 ovate or oblong nearly equal spreading lobes ; arid 

 the stamens almost equal, their anthers blunt at base. 



19. M1MULUS. Herbs, with opposite leaves, and single flowers in the axils of the 



upper ones. Calyx prismatic, 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. 



20. TORENIA. Trailing herbs, with opposite leaves and axillary flowers. Calyx 



prismatic, 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 equalling 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. 



2. Stamens with f/norl anthers only 2, a pair of sterile ones or abortive f laments 



generally present a/so: jlowers small: calyx ^-parted: corolla, 2-lipped : leavts 

 opposite, with single, Jlowers in the axil 'of the upper ones : peduncles simple 

 and bractless. 



21. ILYSANTHES. Spreading little herbs. Upper lip of the short corolla erect 



and 2-lobed: the lower larger, spreading, 3-cleft. Upper pair of stamens 

 with good anthers, included in the tube of the corolla; lower pair borne in 

 the throat and protruded, 2-forked, Avithoiit anthers. Stigma 2-lipped. Pod 

 many-soeded. 



22. GRATIOLA. Low herbs. Upper lip of the corolla either entire or 2-cleft; 



lower 3-cleft. Stamens included; the upper pair with good anthers; the

3. Stamens willi anthers 4, the fifth stamen present as a barren /lament or a scale : 



calijx ^-parted or of 5 imbricated sepfils: stir/ ma simple: leaves chiefly oppo- 

 site : fltwers in the axils of the upper leaves, or iclwn tltese are reduced to 

 bracts forming a terminal panicle, or raceme : peduncles few- flowered, or u'htn 

 one-flowered bearing a pair of bractlets, from the- axils of whit h Jlowers may 

 spriny : pod many-seeded. 



23. SCROPT1ULARIA. Homely and rank erect herbs. Corolla small, with a 



globular or oval tube, and a short border composed of 4 short erect lobe- and
