MUTATIONS IN VIOLA. 187 
color of the corolla. This blueness of the corolla was one of 
the facts which, taken along with the massed rootstocks, leaves 
and flowers, convinced me that the plants could not be referred 
to V. emarginata, although the locality was one in which that 
species might be looked for. 
A year after having published it I transferred a clump of it 
to my garden, and the one self sown seeding from it had corollas 
almost purple, so that I have since then suspected the whole 
thing of being a mutate, of which V. emarginara is the parent, 
notwithstanding that the characters of it are good enough for a 
proper species. 
V. ABERRANS, Greene, Proc. Philad. Acad. for 1903, p. 683. 
This offspring of V. jimébriatulais the first violet observed by me 
which at the very outset impressed me as indubitably a mutate. 
In the midst of a colony of the true V. fimbriatula near Wash- 
ington there grew one plant differing from all the others not 
only by its cordate long-petioled leaves with no hint of the 
dentation, but also by the fact that its caudex was multicipitous. 
I transferred the plant to my garden. It flourished there for 
three years. Seedlings from self-sown seed sprang up around it 
the second year, others the third year, seven or eight of them 
in all, Out of those one was a revert to V. fimbriatula, a perfect 
revert, without shadow of approach to its true parent, while the 
other six or seven were as precisely true to the parent. I noted 
at the time some characters of calyx and corolla, and wrote them 
down, but the manuscript is lost. 
After all this, the violet came in to me, in the dry, from Mr. 
Witmer Stone, for my opinion as to what it should be, and I 
gave him my manuscript name for it, and my view of its origin. 
He afterwards expressed his own—a zoologist’s—opinion of it. 
It is not now rare in the U. S. Herbarium, and has come in 
from various localities; and here, notwithstanding my own 
exclusive right to the name, I find several sheets have been 
labelled by Mr. House “ V. aderrans (Stone) House” ! 
V. SECEDENS, Greene, Pitt. v. 121. At the place of publica- 
tion this has been sufficiently indicated as, in my opinion, a 
mutate; bearing just that relation to V. subagtitata of the West, 
which V. aberrans bears to V. fimbriatula of the East.
