BRAINERD: STEMLESS VIOLETS OF THE SOUTH 7 
The leaf is primarily three-parted, and when well developed each 
of the three segments is further trisected, and then each of these 
subdivisions once more cut into 2-4 lobes. (See PLATE I, FIGURE 
2.) In the smaller leaves and in those that appear in summer the 
lateral primary segments are often imperfectly or obscurely tri- 
sected and seem to be somewhat irregularly pedate; and this 
fact doubtless suggested the inappropriate name of the species. 
In V. pedatifida the middle segment is never uncut, as in leaves 
strictly pedate, but is even more dissected than the lateral seg- 
ments.

All the species of white stemless violets found in the North, 
except Viola renifolia, are found also in the territory embraced 
in Dr. Small’s Flora; and in addition one not found in the North, 
V. vittata Greene. But only two of the northern species, V. 
lanceolata and V. primulifolia, are widely distributed in the South 
—V. pallens, V. blanda, and V. incognita being restricted there to 
the upland region of the southern Alleghanies. 
In this group pubescence proves to be an inconstant character. 
VIOLA PRIMULIFOLIA, which in the extreme North is quite glabrous, 
becomes more and more pubescent as we go southward, untili n 
the Gulf States it is often densely villous on the petiole and lower 
leaf surface. This variety was first noted by LeConte, and named 
var. villosa by Amos Eaton, when he adopted in his Manual 
LeConte’s treatment of the genus. Mr. Pollard’s var. australis 
seems to cover the same ground. 
VIOLA VITTATA Greene (V. denticulosa Pollard), an odd species 
with long linear leaves, is at times almost glabrous, and seems
