126 PITTONIA. 
flowers developed in my garden at Brookland, D. C., in the 
spring of 1899, the roots having been transplanted from the 
original station by myself in the summer of 1898. The 
emarginate character of the petals is very probably incon- 
stant. Such petals occur in true V. pedatifida now and then. 
16. V. pepata, Linn., var. INORNATA, Greene, Pitt. iii. 35: 
When seven years since I was enabled to demonstrate, 
what all botanists for a hundred and fifty years before had 
remained unaware of, namely, that the plant of Maryland 
and Virginia with two dark velvety upper petals was 
typical V. pedata, I gave the above varietal name to what 
I then called the “northern plant” which differs from the 
southern in several particulars, and among them in never 
displaying any dark-colored petals. 
I really ought to have been somewhat more definite as to 
the habitat of the variety inornata; for what I had in mind 
was the northwestern and inland plant common in the 
region of Lake Michigan and far to the westward. This 1s 
the “V. pedata” with which I was familiarly acquainted 
now nearly fifty years since in Wisconsin, and with my 
recollection of which the two-colored Potomac Valley plant, — 
in 1896, stood in contrast. 
What I would designate as the southern plant, and which 
extends along the Atlantic slope of the Continent all the 
long way from Maine to Florida, and which neither north- 
ward nor far southward seems to be two-colored as to its 
corolla, is either an aggregate of several species, or will at 
least be resolved, some day, into a number of marked 
varities. 
The northwestern plant, seems to be less variable and cer- 
tainly has a less"extended range. It is never “ glabrous;” & 
character named by Mr. Pollard in Brittons’ Manual, and
