BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 623 
forms which have probably resulted from hybridization in the 
indefinite past. We have no pure Viola sagittaia in Vermont, but 
most of your odd forms turn up from time to time in the Champlain 
valley.” 
*VIOLA FIMBRIATULA Sm. X OBLIQUA Hill. 
_ Asingle cluster growing with Viola obliqua on a shaded bank 
at Watts Run, June 9, 1909. 
Petioles and peduncles pubescent with short spreading hairs, 
the leaf blades similarly clothed on the veins beneath, sparsely 
appressed-pubescent on the upper surface, ciliate; later leaves 
ovate-oblong and openly cordate, or somewhat attenuate-triangu- 
lar from a subtruncate base, coarsely and rather closely sinuate- 
dentate towards the base, the largest 6 cm. wide by 9 cm. long 
on petioles 10-15 cm. long; apetalous flowers few, mostly weakly 
developed, the buds lanceolate and acute, their petioles ascending- 
horizontal or declined. 
This plant grew in shade beside a mass of Viola obliqua. No 
Viola fimbriatula was found with it, but the specimens are obvi- 
ously intermediate between these two species, and on Nantucket 
no others are possibly to be assigned as parents. 
*VIOLA ODORATA L. 
An old garden plant of the town, here and there strayed 
along streetsides and established in neglected yards. One 
particular tuft has grown for many years in a crevice between 
the paved sidewalk and a brick wall on North Water Street. 
It was first noticed in 1899, and has been found at the same spot 
on every subsequent visit to the town, evidencing both the 
tenacity of the plant and the undisturbed repose of the town 
streets. 
VIOLA LANCEOLATA L. 
Very common in bogs and low grounds and in wet sandy soil 
about the borders of ponds. In full flower May 30, 1908, June 3, 
1909, June 3, 1911, and still commonly in flower June 15; some 
flowers remaining June 25, 1910. 
Plants growing with Viola pallens and appearing more or less 
intermediate with it, and others approaching Viola primulifolia 
are not improbably hybrids.
