ASTER AMNICOLA 289 
of A. curvescens, and inflorescence-form that of A. umbelliformis, 
both not really very closely akin. A. vittatus is its intermediate 
to A. curvescens. A. sylvicola is its correlative, of mountain wood- 
land depths. All of these are, however, markedly unlike A. am- 
nicola in appearance and in many important minute characters. 
When straying beyond its habitat of best development, under 
riverside bushes, into the open sun, A. amnicola produces truelli- 
form thicker and more rigid leaves, smaller, but still palish green, 
and strigose beneath ; remaining still unlike any other of the Cur- 
vescentes. 
** Radical leaves smaller, ovate-cordate, thin but firm, dark 
green. Species 52-54. 
52. Aster sylvicola sp. nov. 
Upright plants of clearings in woods, with small dark suben- 
tire cordate leaves, square sinus, villous veins, shallow-chanfer 
bracts, and about 10 rather short rays. 
Name, = forest-dweller; from its habitat, as opposed to 4. amnicola, 
to which it is ri deditos 
Fic. 67, plant + tian Hunter Mt., Catskills, Se. 6, 799, in hb. Bu., 4 natl, 
size, with radical groups 1. Only external rays indicated 
Stem erect, terete, brownish-green, 2 ft. high or less, smooth 
and glabrous. Radicals a violiform tuft, about 5, cordate, with 
deep narrow sinus, 3 x 2% in. or less. 
Leaves all very dark green above, very pale or whitened be- 
neath, of subentire aspect, but really low- serrate, with petioles at 
first much longer than the leaf, still as long as the leaf in the 
middle caulines 
Leaf-form cordate, elegantly and symmetrically curved, merely 
acute; the upper caulines becoming reduced, passing from cordate- 
ovate, acuminate with broad shallow sinus or truncate-base, to 
lanceolate with winged base, or to short-oblong. 
Inflorescence irregularly convex, loose, with long suberect 
branches, and inconspicuous or larger oval-elliptic axiles and 
rameals, 
eads not many, convex-topped, small and delicate, on very 
long tenuous pemved pedicels, quincunx with very deep green- 
tipped bracts, -5 js in. high. 
racts more i Ant and more sharply contrasting than in 
many allies, the pale portion being variegated by the long acute 
green-tip. Rays not so long as the last, § in. or less.
