delimitation occur northward aiid westward, through the land 

 of hills, of parallel mountain-areas with intervening trough-like 

 valleys, of red soil (leri\ed from Triassic rock or (jf black soil 

 from OrdoN'ician limestone, of various soils derixed from the 

 ridges of shale, gneiss and sandstone, appears self-evident. In 

 the northern portion of our territory glaciers, building lake and 

 gravel habitats, have left us a new series of environmental con- 

 ditions. Mr. Taylor's suggestive Flora does not attempt the 

 detailed analysis of distribution which is demanded. I believe 

 that the careful working-out of the ranges of the species of a 

 few well-selected families of plants will give the knowledge we 

 need for the dividing into phytogeographic areas of this varied 

 inland — knowledge which will be nearly as definite as if multi- 

 plied by such a wealth of data as is presented by Dr. Stone. 

 The problem is fascinating and it is with reluctance that I realize 

 that the Scrophulariaceae have not yet been observed over a 

 sufficient area or with sufficient thoroughness to warrant basing 

 upon this study any contribution toward such a survey. 



Our present study then attempts but these three goals: to 

 present keys contrasting the genera and species of Scrophulari- 

 aceae in our flora, to make certain the nomenclature, and to give 

 preliminary observations of distribution. 



A. Corolla with the posterior lobes external in the bud. 



(Antirrhinoideae.) 



B. Filaments five. Stigma capitate. Capsule septi- 



cidal. Sepals five, distinct. 



C. Corolla rotate, slightly zygomorphic, its lobes 



much longer than the tube. Filaments all with 



fertile anthers. Leaves alternate. I- Verbasceae. 



I. Verbascu7n. 

 CC. Corolla tubular-campanulate, zygomorphic, its 

 lobes shorter than the tube. Posterior fila- 

 ment without anther, the others didynamous. 



Leaves opposite. 11. Chelon'e.\e. 



Corolla white, lavender or pink, pubescent or 

 puberulent within, its anterior lobes pro- 

 jecting. Sterile filament slender, filiform, 

 white. 

 Corolla membranous, white or lavender, 

 puberulent or somewhat pubescent within 

 over base of anterior lobes. Sterile fila-
