ASTER MACROPHYLLUS - M 
55^ Aculeated form. Close-colony form with short root- 
stocks, very peculiar in aspect from the dark blackish-green leaves 
held stiffly outward at a straight slant continuous with the rigid 
blackish or purple petiole. Leaves very rough in life, and firm, 
somewhat triangular-cordate. Teeth long ine coarse, often over 
i in. long, sometimes even i in., with is projection, usually 
dorsally straight, though sometimes curvescent, with a strong 
aculeus which is very salient in life and points upward, giving the 
leaf its characteristic aspect. Radical petioles short, stout, succu- 
lent, enlarged at the base, not at all erect, but slanting at about 30? 
instead of 75? as usual. Radicals 3, sometimes 4, of which the 
2 last are nearly equal, and the 1 or 2 first are very much smaller, 
a little more acuminate and asymmetrical than in the type. Lower 
caulines 3, cordate-oblong, suddenly incurved-acuminate, sharp 
serrate. Stem smooth, blackish purple, its many leaves sometimes 
chiefly small, subentire, sessile and narrow oblong.  Bracts short, 
more rounded than in type. Inflorescence rather small and dense.

55^ Bunch-top form. Small leafy plants about 124 ft. high 
or less, with smooth stout ascending stem brownish and subsuccu- 
lent in life, glabrate and reddish with age. Leaves not large, only 
moderately rough ; radicals acne those of A. multiformis, 
2, narrow-cordate, short-acuminate, rather symmetrical, 
aculeately forward-serrate. Some wing-based oblong-acuminate 
caulines are more as in typical A. macrophyllus, as are the lilac 
rays, which however tend to assume a livid or slaty-lavender cast, 
and to fade whitish. Inflorescence small, densely convex. B 
thinner, longer, and less puberulent than in typical 4. "aps ur 
highly ciliate. Heads small, about 34 in. broad, 36 in. In 
small well-sunned colonies with grass between, under esolated 
trees ; sometimes 100 plants within 6 ft. with slanting stems about 
I5 in. high, and with the radicals overtopped by intermixed grass- 
blades
