ASTER CAPILLARIS 177 
widely-separated inflorescence (according to age); its crimson 
disks; and the leaf-form of its axiles. Like A. glomeratus in the 
numerous strigose hairs of the stem, and of the veins beneath ; in 
the convex-topped dense young inflorescence; the ovate-acute 
cauline leaf-form, the dry and crumbling leaf-texture, and winged 
axiles. Like A. oviformis in form and thinness of radicals; and 
somewhat so in cauline leaf-form. 
Possibly this isa hybrid of A. oviformis and A. persaliens ; but 
I do not find evidence enough to warrant describing it as such, 
for it is unlike both those species in the remarkable deep-forked 
tendency of the inflorescence, with branches chiefly about 35° i 
angle. Itis also unlike both in its large size of heads, and the 
thinner texture of the chiefly acutish bracts. 
N. Y., Silver Cr. ravine; growing out of the shale-wall of the gorge, near 
its base, with pies 4X 1% in. or less, Au. 17, '96. A. oviformis was then grow- 
ing within a rod, and 4. persaliens may have been near, certainly various allied Di- 
varicati were so.

Species 19-21. 
19. Aster virgularis sp. nov. 
Small wand-like plants with little taper acuminate leaves of 
elegantly bicurve base, moderate or sharp sinus, closely serrulate 
or minutely slit-toothed margin, pale narrow bracts and reddish 
disks. 
Name, from L. virgula, t € wa 
Fic, 27, plant from Bryn Mawr MA. vic. N. Y., Se. 2$, 97; in hb. Bu; à, 
characteristic lower leaf; d, a upper leaf. 
Stem slender, chiefly about 1 ft. high, wandlike, erect and 
reddened ; growing in loose clusters. 
Leaves somewhat ovate-acuminate in type, incurving into a 
long acuminate termination from a broad base abruptly rounded 
into the moderate sinus. 
Radicals and lower caulines broad-scutiform, the latter sud- 
denly long acuminate, small, 1% x 1 in. chiefly, elegantly curved 
in broadly sweeping bicurve base to a small brace or incurved 
sinus. Large leaves scarce, but sometimes reaching 21% x 134 in 
Middle caulines narrow-scutiform, with straightish or slightly 
incurved sides, and also with elegant bicurve brace, but the sinus 
sharp. 
r caulines and axiles narrow, triangular-lanceolate, with 
atraightish sides from a single-curve round base, the sinus having
