314 PITTONIA. 
friend T. H. Kearney, Jr. The autumnal specimens were 
collected by himself in September, 1897. "There are some 
suggestions of affinity between this and a certain hitherto 
somewhat obscure southern violet, of which I shall next 
make mention. : 
V. ESCULENTA, Ell. Sk. i. 300 (as a synonym under V. pal- 
mata, var. heterophylla): V. heterophylla, Muhl. in Le Conte, 
Ann. Lyc. N. Y. ii. 139 (1828), not of Poir. Encycl. viii. 646 
(1811) It is time that renewed attention should be given ' 
to the long neglected V. heterophylla of Muhlenberg, first 
fully described by Le Conte in his admirable monograph. 
It is said to be a plant of wet clayey lowlands in the Caro- 
linas and southward, not occurring at all in the hilly or 
mountainous districts. Its leaves are said to be considerably 
diversified, the whole plant glabrous and slightly succulent, 
and in use as a pot herb by the negro population. Le Conte, 
who knew the species well, and, as I have said, was the first 
to fully describe it, left an unpublished beautifully finished 
and colored figure of it, and this is in my possession. I have 
been endeavoring to match this figure, in various collections 
of southern violets; but the only specimen of it hitherto de- 
tected by me is one in the herbarium of Dr. Charles Mohr 
of Mobile. It is an old specimen, collected long ago, in 
Louisiana, by Carpenter, seems wholly unlike any other 
plant known to me, and well matches Le Conte's unpub- 
lished plate, of what he called V. heterophylla, Muhl. 
V.cusPIDATA. Acaulescent, low, at time of petaliferous 
flowering 3 or 4 inches high: leaves round-cordate, cucul- 
late, crenate-serrate, veiny and rugose, short-hirsute as to the 
`. petioles and along the veins beneath, sometimes also on the 
upper face, and the margins ciliolate: sepals obtuse, cilio- 
late from the base to the middle: corolla about 8 lines long 
and 9 in breadth, deep blue, the paired petals broad-obovate, 
abruptly acutish, the odd one nearly equalling those next to
