Stigma two-lipped. Inflorescence simply racemose. Leaves 

 opposite. Herbs. 

 Capsule septicidal, or secondarily also somewhat loculici- 

 dal; placentae simple. Sepals distinct or nearly so. 

 Leaves and capsule somewhat glandular-punctate. 



I. Gratioleae, 

 Capsule locuhcidal (only tardily septicidal, if at all) ; placentae 

 branched and widely spreading. Sepals united over one 

 half length. Leaves and capsule not glandular-punctate. 



II. MiMULEAE. 



Stigma capitate. Capsule septicidal. 



Leaves alternate. Plant frequently with stellate hairs. 

 Corolla slightly zygomorphic. Filaments all with fertile 

 anthers. Inflorescence simply racemose. 

 Corolla yellow or white, rotate, its lobes much longer 

 than the tube. Filaments five. Herbs. 



III. Verbasceae. 

 Corolla rose-pink with orange markings, campanulate, 

 its lobes shorter than the tube. Filaments four (the 

 posterior lost). Shrub. IV. Leucophylleae. 

 Leaves opposite. Plant never with stellate hairs. Corolla 

 tubular-campanulate, zygomorphic, its lobes shorter than 

 the tube. Filaments five, the posterior without anther, 

 the others didynamous. Inflorescence simply racemose, 

 or of cymose fascicles. Herbs. 



V. Cheloneae. 

 Capsule loculicidal, the septum and adjacent capsule-wall per- 

 sisting, the remaining wall splitting irregularly. Corolla 

 saccate or spurred at base of anterior petal. Leaves alternate. 

 Herbs. VI. Antirrhineae. 



Corolla with the anterior lobes external in the bud. Herbs. 



(RHINANTHOIDEAE.) 

 Stamens two, the postero-laterals present, the antero-laterals 

 completely lost. Antero-lateral lobes of corolla external in bud. 

 Not parasitic. Sepals four, the posterior lost. Posterior 

 lobes of corolla completely united. Capsule loculicidal. 



VII. Veroniceae. 

 Stamens four, didynamous, the antero-laterals usually sUghtly 

 the longer. Usually, perhaps always, parasitic on the 

 roots of other plants. 

 Sepals five, alike, more or less united. Corolla-lobes all 

 somewhat distinct, the two posterior spreading or arched 

 or flattened; anterior lobe external in the bud. Capsule 

 loculicidal. VIII. Buchnereae. 



Posterior sepal shorter or wanting. Corolla decidedly two- 

 lipped, the posterior lobes united and arched nearly to apex, 

 the anterior lobes shorter; anterior or one antero-lateral 

 lobe external in the bud. Capsule septicidal or loculicidal. 



IX. Rhinantheae.
