projecting, px incurved, narrowly elongate and falcate or con- 
cavo-conve With these occur also, couchant and curvescent 
teeth as in p persaliens. Winged petioles frequent, even through 
the middle of the stem. Like .4. aja its leaf-substance 
is thickened, and curvescent teeth are common. . Inflorescence- 
form particularly like that of 4. tober each long flagelli- 
form branch bearing a convex or dome-topped subumbelliform 
long-pedicelled cluster. Bracts semble those of A. persaliens. 
Rays become olivaceous, and disks purplish.

5. Aster atrovirens sp. nov. 
Long-leaved tall wand-like plants of moist woods, the margins 
closely slashed with long slender teeth, the small heads crowded 
in a small leafy-based convex inflorescence often continued down 
several axils, new heads long continuing to develop ; plants of 
weedy aspect and deep green (whence the name, L., blackish- 
green). 
Fic. 13, from plant of Jerome Av., vic. N. Y., Oc. 2, 1901, in hb. Bu.; with 
bract of the extremest obtuse type ; and eed sek leaf from low down the stem. 
Stem green or brownish-green, 2% ft. or less high, very leafy, 
nearly straight, erect or assurgent. 
Leaves very dark green, paler beneath, thin but rather firm, 
smoothish : petioles chiefly rather short and slender, not equal- 
ling the leaf-breadth. Leaf-form somewhat triangular and ovate- 
acuminate, sloping below into narrow lobes, with a broad moderate 
sinus, the teeth close, long, sharp and slender, their bracts 
straightish or at least not so continuously and strongly curved as 
in A. persaliens. Lower caulines cordate-ovate, acuminate, 5 x 
in., their coarse teeth often 49; in. deep and 1⁄4 in. long ; their fal 
sinus rather shallow, vesci in the middle. Middle caulines 
Ovate-acuminate, 5 x 2 in., or 3% x 1%, the slender petiole I in. 
or less. Upper si ' lance- acuminate, 3 A x IM in. with 
short broad wing base, and long entire acumination. Axiles like 
the last, usually retaining the short broad wing ; commonly be- 
coming triangular-linear, finally only 1 14 x 14 in. at an inch or so 
from the top xd the stem.  Rameals few or remote, ovate, ‘entire, 
. or nearly so, 34 in. long 
Heads small, leaty-subtended, closely branched or subsessile,
