30 PITTONIA. 
deltoid ; both faces of all sparsely appressed-perbescent : petali- 
ferous flowers not seen, the few apetalous ones on slender and 
not very short horizontal or ascending peduncles. 
In woods near Houston, Texas, 17 April, 1900, B. F. Bush; 
the specimens distributed for V. Langloisiz, to which species this 
makes no near approach in any way. The foliage is of most 
peculiar outline, and might be described as narrow-reniform, 
with a large apical cusp. 
V. Austin. Related to V. cognata of the Rocky Mountains, 
but the slender rootstocks branching and the plants therefore 
tufted ; both shorter as to stature and leaves and flowers larger; 
herbage light-green and altogether and unvaryingly glabrous: 
leaves mostly subreniform-cordate, at time of petaliferous flow- 
ering 1 to 2 inches broad, the length rarely 1} inches, abruptly 
tapering to the petiole, obtuse, evenly crenate: peduncles equal- 
ling or slightly exceeding the leaves, bibracteolate a little below 
the middle: sepals lance-oblong and linear-oblong, obtusish ; 
corolla commonly an inch wide, petals blue, spatulate-oblong, 
obtuse, all nearly equal, the lateral pair only scantily bearded, or 
apparently sometimes not at all so: fruiting peduncles of the 
late apetalous flowers erect, shorter than the petioles, their cap- 
sules about 5 lines long. 
Subalpine in the Californian Sierra, the best specimens of 
petaliferous plants being from Mrs. Austin, Butterfly Valley, 
Plumas Co., 1876. The late summer state, with capsules from 
apetalous flowers, known only in a sheet collected by my former 
pupil, Mr. Milo 8. Baker, in Big Valley, Lassen Co., 3 July, 
1893. At the time of my proposing the V. cognata ‘segregate 
from V. cucullata I placed these Californian and some other 
Pacific coast forms tentatively under V. cognata ; but in the 
light of additional material I see cause to sepafate them. 
V. GALACIFOLIA. Slender rootstocks more or less multicipi- 
tous and the leaves and peduncles consequently tufted, 4 to 6 
inches high at petaliferous flowering, slender, of thin texture
