delimitation occur northward and westward, through the land 
of hills, of parallel mountain-areas with intervening trough-like 
valleys, of red soil derived from Triassic rock or of black soil 
from Ordovician limestone, of various soils derived 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 eesti 
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.
