ANOTHER HYBRID BETWEEN A WHITE AND A BLUE

Ezra BRAINERD. 
VIOLA CUCULLATA X PRIMULITOLIA. (V. lavandulacea Bicknell, 
Torreya, iv. 130.) This hybrid I discussed briefly in RHODORA, viii. 
52, remarking on its evident relationship to V. cucullata, and querying 
if the other parent might not be such a form of F. emarginata as I had 
in cultivation from Washington, D. C., with strongly decurrent base 
and leaf-outline of V. primulifolia. Soon afterward Mr. Bicknell in 
conversation stated that he had thought the doubtful parent might be 
the real white-flowered V. primulifolia. I replied there was no pre- 
cedent for so remote a cross in Viola; it must be considered quite 
improbable. But Mr. Forbes's recent discovery of V. Brittoniana X 
lanceolata throws a new light on the problem. A critical study of 
his plants leaves one in no doubt as to the correctness of his conclu- 
sions; the presence in them of stolons can be accounted for only on 
the hypothesis of a sexual union between a purple-flowered and a 
common white violet. The precedent being established, we are 
prepared to weigh the evidence sustaining Mr. Bicknell's opinion as 
to the parentage of his V. lavandulacea. 
The marks of V. cucullata are indisputable, especially the long-auri- 
cled slender cleistogamous flowers, the short glabrous spurred petal, 
the knobbed beard on the lateral petals, and the finally acuminate 
leaves. The marks of V. primulifolia are also conspicuous, namely, 
— the truncate and decurrent base of the leaf, its obscurely crenulate 
margin, its numerous nearly parallel veins diverging from the midrib,
