268 DESCRIPTION OF ASTERS ; CURVESCENTES 
Allies. Its nearest affinity seems A. Erzensis, which differs in 
its glabrate leaves almost without hair on the veins, in its non- 
ciliate bracts, its compound inflorescence of separated cymules, 
etc. A. Schreberi and the other Schreberan species differ in their 
larger and more numerous radicals. A. Julianus has a taller 
inflorescence, thinner leaves and less pubescence. Most typical 
plants of A. glomeratus are almost unique among Biotian asters in 
their small bristly crenate rounded-cordate apiculate lower caulines ; 
but numerous variants diverge from these toward the species above- 
named and toward A. divaricatus. 
Variants : 
46? Globular form, the extreme of condensation ; branching 
miniature. With the type at Chautauqua, Cattaraugus and Albany 
county localities. 
46° Expanded form; the opposite extreme; sometimes 200 
beide with inflorescence 8 in. across and 9 in. high ; Hee reach- 
ing 4 in. high, rays 8 to 10, the lamina 45 in. long, =; broad. 
Localities in W. N. Y. 
46* Pedunculate form ; leaf-form not, as in all the preceding, 
diminished gradually to the top of the stem ; but with the leaf- 
series suddenly arrested after about 3 lower leaves, the numerous 
remaining leaves small and bractlike, 1 in. long or less, with very 
short winged petiole, all nearly of one size. Common with the 
type, W. N. 
46? Pomarial form, orchard-like plants resembling little loosely- 
globose apple-trees standing at little spaces apart with grass or 
radicals only between; smallest of the Curvescentes, 1 or sometimes 
1% ft. high. Radicals often 6 and all without sinus ; caulines all 
remarkably small. Leaf-form ovate-triangular, obtuse. Texture 
heavy, flabby, a little rough while fresh, hispidulous when dry 
above and bristly beneath. Teeth sharper but bracts more rounded 
than in type. Inflorescence a dome-like top quite large for the 
plant, 6-8 in. across ; not densely flowered. 
W. N. Y., Hanover, Rosebrook woods, Au. 31,'99; the type growing near. 
465 A emia xA. macrophyllus pinguifolius ? a probable 
hybrid, both assumed parents growing in the vicinity. Leaves 
smooth, thick, flabby ; upper caulines oblong, with truncate base 
and shallow teeth ; lower caulines shallow-crenate ; rootstock 
stout. Tends to glutinous hair and pedicelled glands, as in A. 
macrophyllus ; but shows all the inflorescence-characters of A 
glomeratus, and also its leaf-form. — Bernhardi’s A. g/utinosus, if 
it were recoverable, should be compared with this. 
W. N. Y., bankside thicket near the mouth of Big Indian Cr., July 31, '96.
