Viola orbiculata Geyer, Hook. Lond. Journ. Bot. vi, 73 (1847). 
This has the large rootstalk, the acutely triangular glandular-margined stip- 
ules and bracts, and the stigma of V. glabella, but it is nearly acaulescent, the 
stem leaves being mostly reduced to mere stipules; the peduncles are much 
elongated, and the leaves are quite glabrous, the margin merely glandular-den- 
tate, not ciliate as in V. glabella. The general outline of the leaf is that of J. 
biflora L.; but it is less caulescent than that species, and differs from it in root- 
stock, stipules, and stigina, as above noted. 
The leaves are mostly radical, numerous, on slender, glabrous petioles 5 to 
10cm. long, with bright-green blade 3 to5 cm. in diameter, generally circular in 
outline, but occasionally slightly elongated, the margin minutely glandular, 
crenate, the sinus of the deeply cordate base closed by the overlapping lobes, 
the under surface quite glabrous, the upper beset with seattered, short, stout, 
appressed hairs. The early-flowering form, with large yellow flowers on long 
peduncles, appears frequently as if acaulescent, nothing being left to represent the 
(usually two opposite) leaves of the sarmentose stem except the scarious, acutely 
triangular, glandular-margined stipules near the ground—the similar peduncular 
bract is quite near the flower. The later basal leaves are larger, on longer peti- 
oles, and in all our specimens exceed the sarmentose stems. The several weak 
stems bear each usually two opposite leaves much smaller than the basal leaves, 
on petioles 1 to 2 cm, long, the blade more ovate in outline, and the basal sinus 
less deep. From theiraxils spring 2 to 4 short-peduncled cleistogamous flowers, 
while the stem continues as a slender, usually leafless, stolon, This does not 
root in any of our specimens, though they are in fruit, and does not exceed the 
long-petioled later leaves; yet it probably does so later in the season.
