ASTER AMPLIATUS 361 
ends (3 x 2% in.), cordate-acute (6 x 5 in.), cordate-oblong, 
acute (517 x 314 in.), etc. 
Caulines begin with the characteristic obtuse and ampliate form 
in large size (to 7x 5 in.), or with broadly cordate-acute leaves 
of similar size, all with long weak slender petioles, these shorter 
however than the leaf-length. Smaller plants sometimes show 
only narrower cordate-oblong lower caulines. 
Middle and upper caulines oval-oblong, broad, irregular and 
asymmetrical, sharply dentate, with expansive broad-wing gash- 
toothed base (as often in A. divaricatus alatus) or in smaller leaves 
with an entire undulatiform wing (as in A. undulatus). Apex of 
these leaves obtuse retuse or acute. 
Axiles like the last (4 x 2% in.), or broad, biacuminate, ser- 
rulate (3 x 1% in.), and sessile. 
Rameals often numerous and conspicuous, obovate or oblong- 
Nee nans by a broad base, acute, minutely slit-serrulate or 
suben 
Ecos broad and irregular, of several or many leafy- 
stemmed, shallow corymbs, each convex-topped and composed of 
8—40 loose heads, with slender, but rather short, pedicels. 
Bracts lingual, rather narrow, rounded at apex, all nearly 
alike but progressively thinner, EC more scarious and more 
silvery-green toward the inmost serie 
Rays rather thin, violet or pale- violet involutely-wrinkled on 
drying. 
Habitat, Catskills, at 2,500-3,000 ft. (Grand-View, E. front of Kaaterskill 
Mtn., Se. 7, '98, in numbers, at several places).

70. Aster sympodialis sp. nov. 
Tall, robust, scattered plants, with thickish, ample, regular, 
low-crenate leaves, broad cordate-ovate leaf-type ; about 3 radicals ; 
numerous caulines, chiefly ovate-oblong with strap-wing or taper 
base; high-ascending or erect branches, each successively over- 
topping its axis, producing a straggling long-pedicelled inflores- 
cence; and with numerous (14-20) long, narrow, fragrant rays 
with obtuse apex and tapering or pedicelled base, violet fading 
white. 
Name, L., from the strong tendency of lateral branches to surpass Fus axis.
