las, and their rounded hydrocotyle-like seemingly entire leaves. 
V. ACHYROPHORA. Low and with foliage of V. landa, the 
pale thin leaves round reniform to subcordate reniform, ob- 
tuse, obscurely crenate, less than an inch broad, on petioles of 
an inch or more, at base subtended by a pair of quite large ovate 
subscarious stipules, these becoming brown-chaffy and persistent 
at the nodes of the slender horizontal rhizome: peduncles seldom 
2 inches high, conspicuously bibracteate above the middle, the 
bracteoles lance-ovate, obtuse, green and erect: sepals oblong- 
lanceolate, acute; corolla white (or possibly pale purplish), fully 
# inch broad, the upper petals oblong-spatulate, the odd one 
much broader and retuse, all glabrous. i 
St. Paul Island, Bering Sea, July 18, 1897, James M. Macoun ; 
the specimens distributed under the name of V. palustris; but 
if the flowers were only one-third as large as they are, the plant 
might pass for V. blanda, but for the peculiar chaffy rootstock. 
V. ARIZONICA. Related to V. cognata, the whole plant as, 
glabrous, but more slender, with smaller leaves, these from 
cordate-reniform to round-cordate, obtuse, beautifully crenate, 
about ĉł inch broad, scarcely as long, the slender petioles more 
than twice as long: peduncles of more than twice the length 
of the leaves, bibracteolate in the middle: sepals ovate-lanceolate, 
short and very obtuse; petals purple, large for the plant, all 
except the odd one with broad rounded limb, that narrower and 
rather shorter than the others. ; 
At Post Spring, Fort Verde, Arizona, 17 April, 1888, Dr. 
E. A. Mearns. The type specimens are in the herbarium of 
the New York Botanic Garden. I do not know other evidence 
of the occurrence of a violet of the V. cucullata subgroup so 
far to the southwest. The leaves are much smaller, the flowers 
as much larger, than those of V. cognata; and the aspect of 
the plant, with its long slender pedicels, is peculiar; more like 
that of my V. crenulata of northern New York, though the 
leaves are not cucullate as in that.
