only 3 prominent: peduncles filiform, pendulous, mostly 1-flow- 
ered, when 2-flowered the pedicels very unequal: perianth very 
small, 4 lines long, of a very deep green, darker than the foliage.

Mutations'in Viola 
Among the North American violets that have been first brought 
into notice through my researches during the last ten years, there 
are several which, at the time of their publication I indicated 
as being perhaps mere abrupt metamorphoses, so to speak, of 
more common and familiar forms; abrupt though perhaps per- 
manent deviations from the names of other species ; distinguish- 
able and demanding to be distinguished from mere varieties by 
the abruptness of their divergence from their parent types, not 
showing those intergradations with it which subsist between 
varieties and their respective type species. 
Over and above those recognized by me at the outset as prob- 
able mutations, there are others which I did not at first suspect 
of having had such origin, but which I have since learned to 
think of as probably belonging to that category; and I wish 
without further delay, to make a list of all which I now view in 
the light indicated, not excluding from the list a few quite old 
species—published as such, at least—the very names of which 
are at this date half-forgotten. 
V. INDIVISA, Greene, Pitt. v. 124, t. 13. To the detailed 
account of this given at the place cited L have to record some 
extension of its known range. It seems to occur in very typical 
condition in the immediate vicinity of Chicago. U. S. Herb. 
sheet, n. 313,261, over a label reading “ Flora of Chicago. Col- 
lected by W. S. Moffatt, M. D.,” contains four specimens, of 
which three are V. pedatifida with leaf segments wider than usual, 
the fourth exactly V. indivisa. The indication of special locality 
is “ Claybanks.” Sheet 339,398, by L. M. Umbach from Naper- 
ville, very near Chicago, 18 May, 1897, is occupied by four spec- 
imens of pure V. indivisa, and in petaliferous flower. The 
corollas are larger than in those garden-grown specimens described
