VOL. XI, NO. 144.—BOTANICAL GAZETTE.—N OV., 1886. 
Memoranda of a revision of the North American Violets. II. 
ASA GRAY. 
Group IV. Subcaulescent, first flowering from the ground, on slender 
mostly subterranean shoots from a deep thick rootstock or caudex, not stolon- 
iferous nor creeping, later more caulescent, always low: corolla wholly or 
mainly yellow, except in last two species, the spur short-saccate: stigma beak- 
less, sometimes with a short antrorse lip, concave, orbicular, antrorse-terminal 
or oblique at the large and gibbous-clavate summit of the style, bearded below 
its margin by a tuft or rarely a ring of stiff and reflexed or spreading bristles. 
Western species, but one cismontane. 
* Leaves undivided, from roundish-ovate or cordate to lanceolate: lateral 
petals slightly bearded or beardless in the same species 
+ Ovary and oval capsule glabrous. 
V. peduneulata Torr. & Gray. California and Arizona. 
V. Nuttallii Pursh. Kansas to the Saskatchawan, British 
Columbia, and the northern borders of California. Although 
some forms of this come near to the next, the capsule should dis- 
tinguish them. A good part of Sir Wm. Hooker’s V. premorsa 
belongs here, namely the specimens of Scouler’s collection. Also 
V. linguefolia Nutt in Torr. & Gray. 
+ + Ovary and globular capsule pubescent. 
of forms, among them the var. venosa (V. aurea, var. venosa Wat- 
son, V. purpurea Kellogg): there are larger-leaved and long-pet- 
ioled forms which approach V. pedunculata, and narrow-leaved 
Ones which are very like V. Nuttallii. 
Leaves finely dissected : subterranean shoots commonly sending up 
their scapiform peduncles from under ground ; the last species more caulescent 
+ Petals beardless, essentially yellow. , 
V. chrysantha Hook. Well marked by the bipinnately dis- 
Sected leaves, beardless and deep orange-yellow petals, the upper 
slightly or largely brown-purple.
