Two new Violets. 
By CHARLES Louis POLLARD. 
“VIOLA PORTERIANA Nf. Sp. 
Mature plant 2-3 dm. high, robust, acaulescent, from a stout 
branching rootstock ; leaves long petioled, evidently exceeding the 
peduncles; blade glabrous or besprinkled with scattered hairs, in 
the early leaves cordate-oblong, obtuse, regularly but not promi- 
nently crenate; in the latter leaves deltoid-triangular, the base in- 
clined to be cordate, obviously decurrent upon the petiole; apex 
obtuse or more often acute; margin ciliate, remotely and very 
irregularly crenate or dentate, the base sometimes with a few 
marked incisions; petiole pubescent below, 13-18 cm. long, the 
blade in the mature leaves 13 cm. long and 7 cm. wide at the 
base; flowers deep purple, as seen in a single withered specimen ; 
cleistogamous flowers on ascending or erect peduncles; capsule ob- 
scurely 3-angled ; seeds pale, not mottled nor pitted. ' (Plate 314-) 
Type specimen collected in the vicinity of Bushkill Falls, Penn- 
sylvania, May 31, 1897, by Mr. Joseph D. Crawford and the 
writer; additional specimens, in a later stage of development, 
were obtained by Mr. Crawford, July 15, near Hamburg, Pa. 
The species is dedicated to Professor Thomas C. Porter, who 
acted as guide on the very delightful Decoration Day. excursion 
of the Torrey Club, and who was among the first to express an 
opinion of its distinctness. In fact there was substantial agree- 
ment among the botanists then present that the plant could not 
well be referred to any known species of the sagittata group, 
although the dried specimens may easily deceive those whose 
conceptions of lV. sagittata and V. cucullata are of the elastic — 
order. It may be distinguished from V. ovata Nutt., an abundance 
of which was collected on the same excursion, by its much greater _ 
size, absence of hirsute pubescence and the relative differences in 
the length of petioles and peduncles. From the true V. sagittata 
it may be known by the broadly triangular leaves, which are quite 
without the characteristic lobes and incisions of that species, and 
also by its habitat, which is dry sandy soil. Very probably it~ 
hybridizes or even intergrades with V. ovata, although I have 
never seen anything approaching it in the hundreds of ovata — 
plants examined, including the typical specimens in the herbarium : 
of the Philadelphia Academy of Sciences, :
