ASTER ORBICULARIS Sol 
Teeth small and inconspicuous, of subcrenulate or serrulate 
type, often doubly serrulate, on upper caulines becoming inconspic- 
uously slit-serrulate. 
Petioles of the radicals slender and much longer than the 
leaves ; of the lower caulines hardly the leaf-length, and quickly 
diminishing into a long series of short strap-wings. 
Middle caulines passing from orbicular-apiculate to ovate- 
oblong ; upper caulines and axiles oblong and sessile, these and 
the lanceolate rameals often amplexicaul and conduplicately- 
sheathing their branches. 
Inflorescence rather close, broad and high-convex, its branches 
subequal, spreading upward at a high angle, 45° or often more. 
Bracts very much alike in shape, the outer acutish, and ovate- 
oblong, and all over green, the middle similar but straight-sided 
and obtusish, the inner with broad whitish scarious sides and broad 
green medial band ; all with sudden short triangular dark-green tip. 
Rays still lilac or purplish.—Some plants of “ A. macro- 
phyllus" Hort. Berlin as represented by specimen of 1839 in hb. 
Gray (labelled by Gray as “ fere 8," i. e. nearly same as A. Schre- 
ert, because so smooth to touch) may have belonged here, having 
nearly orbicular lower caulines with deep narrow sinus, obtuse or 
with slight apiculation, subentire or faintly denticulate; with few 
glands and little hair. 
Habitat, rocky shores and borders, in considerable sun ; Maine 
to L. Erie. 
Examples : 
e., * Bar Harbor, dry thicket, Au. 26, '97," Di; in hb. Du., ** with 
camphoric odor on sweeping the hand over the upper part of the plant; abundant in 
edge of woods and in grass near; not forming plantations but separated.”

58. Aster biformis sp. nov. 
Small stocky plants with thick roughish spongy leaves and 
dense convex corymb, growing in small sunlit grass-mixed patches, 
the few basal leaves cordate-oval and closely crenulate, an abrupt 
series of little ovate-oblong leaves following above. 
says L., from this double leaf-type.
