ASTER DECAPHYLLUS 393 
an inch or two up the flowering stem as if grafted on; but usually 
it crowns the rootstock closely, not to be followed by the flower- 
ing-stem till another year. 
Leaf-type thick, firm, subsucculent, glabrate, very dark green, 
very rough above when dry, very smooth when fresh, minutely 
rugulose with impressed veinlets, and thus closely areolate above, 
each areola having 2 or 3 whitish papillae and many pale scurf- 
like d ots. 
Glands scattered over the leaves beneath are minute, spherical, 
subsessile, colorless or amber-like ; such granule- glands continue 
over the involucres, branches and upper stem, on the pedicels 
mixed with scanty minute puberulence. 
Lower caulines include some sharp-cordated ovate-acuminate 
or lanceolate leaves with narrow petiole ; and a non-cordate round- 
based oval or ovate-lanceolate type with long undulatiform petiole. 
Middle or chief caulines oblong-elliptic or ovate-oblong, 
acuminate, close-serrulate, 317 x 1% in., with a taper strap-wing 
often forming an additional inch. 
Jpper caulines and rameals oblong-lanceolate, with contracted 
sessile base. 
Teeth closely aquiline-serrate in 1st and 2d radical forms, long 
straight-serrate or coarsely crenate-serrate in chief radicals, ob- 
scurely serrulate in caulines 
No obvious hair present. 
Inflorescence branches given off at a high angle, 70°-80°, 
prolonged and leafy, seldom rising to a uniform level. 
Bracts oblong-lingual, quite uniform, with acuted apex but 
obtusish at its termination, with green or reddened medial band 
and pale or white thin scarious mar 
Rays oblong, of a beautiful m pom or blue-violet, paling 
slowly ; of nearly uniform breadth, about 7; in. long, slightly up- 
raised along the edges, appearing entire at the rounded end, but 
minutely tridentate under a lens. 
Disk-flowers composed 24 by the filiform, greenish tube, rather 
gradually swelling into the upper %, which forms a narrow purple- 
brown bell with its lobes 17 or even 24 of its e as in A. /usstet. 
Achene cylindrical, faintly about 10-striat 
Pappus rufous in 5 years. 
Habitat, rich openings and clearings in deciduous forests, Maine 
and the Taconics to L. Erie. 
Examples : 
Maine, Cumberland, Se. 15, '85, J. Blake in hb. T. C. Porter 
ass., Zaconics, Mt. Ethel, oak-clearing, near Melius’ corner, Au. t5-Se. 5, 
1903 ; flowering-stems without radicals ; abundant radical rosettes set for next year’s 
flowering ; but not visible yet May 1, 1904.
