quite the mode of growth usual in caulescent violets, but not ) 
otherwise known in any North American acaulescent species. 
V. PARNASSIFOLIA. Size of the last, the rootstock similar’ 
but petioles and peduncles rather stout and the whole herbage 
glabrous and somewhat fleshy: leaves all subreniform-cordate, 
abruptly acutish, within the basal sinus tapering abruply to the 
petiole, the margin only obscurely crenate: peduncles little sur- 
passing the leaves, bibracteolate near the middle, the bracteoles 
small but green and ascending : sepals oblong-lanceolate, acute; 
petals with oblong-obovate limb, the odd one like the others and | 
as long; the corolla as a whole about } inch broad. 2 
Distributed from Butterfly Valley, Plumas Co., California, by 
Mrs. Austin in 1876, under the name of V. blanda. But the 
species is most distinct; the very firm leaves much like those of - 
some Parnassia in form and texture; the peduncles and petioles | 
reddish or purplish, as seen in V. /anceolata and its nearest 
es.

V. ANODONTA. Slender, 3 to 5 inches high at petaliferous 
flowering, from slender horizontal or ascending white rootstocks : 
leaves ł to 14 inches broad, not quite as long, in outline subor- 
bicular, with shallow open sinus at base, or almost truncate at 
base (the outline then semiorbicular), of very thin texture £0 
very remotely and obscurely crenate as to appear entire, glabrous 
or with a few scattered hirsute hairs about the summit of the- 
long slender petiole, and the base of the leaf: peduncles almost 
twice as long as the leaves, bibracteolate below the middle, the 
bracteoles though small green-foliaceous : sepals broadly oval 
(more than half as broad as Iong) and very obtuse: limb of the 
white petals obovate, the odd one very broadly and almost trun- 
cately so and shorter; the corolla as a whole rather more than i 
+ inch broad, : 
Known only from the mountains of Fresno Co., California, 2 
where it was collected by Mrs. Peckinpah in 1890. Very note- 
worthy among plants of the V. Zanda group for its large corol- —
