332 . Description OF Asters; MACROPHYLLI 
Fic. 79, plate 12, plant of Silver Cr., N. Y., Au. 17, '96, in hb. Zz.; un- 
usual in its trifurcate habit. 
A. macrophyllus biformis Burgess in Br. and Br. Ill. Fl. 3: 360; with 
original description 
“ Small, stocky, with 3 or 4 small oval closely crenate spongy- 
thickened lower leaves with long slender petioles, the sinus deep, 
narrow, the teeth triangular to semi- 
circular ; stem-leaves crowded, much 
reduced, subentire, ovate-oblong, 
i inflorescence nearly 
grassy sunny situations, forming 
small patches, Maine to Ontario 
and L. Erie.” 
Stem rigid, chiefly 1 ft. high, 
somewhat zigzag, reddened, gla- 
brous below, covered above with 
short stiff glandular stubs. 
Leaves apple-green, much red- 
dened in fall, impressed-venulose 
beneath under a lens. Leaf-form 
oval-acute with deep rather narrow 
sinus ; these leaves 3, or sometimes 
2, 4 Or 5, about 3 x 2 in. or less. 
a) é Petioles stiff, fleshy, naked, not 
Aster biformis f widened below but continuing terete 
Fic. 78 to the stem, all erect and succes- 
cui sively shorter, the first much longer 
than its leaf; resulting in bringing the large leaves nearly on a 
level, just elevating them above the grass-sward. In plants not 
closely surrounded by grass the leaves are separated and spreading. 
Little leaves 8-10, sometimes 16, crowded in small plants, re- 
motish on well grown plants (occupying then 6-8 in.), On the 
less-usual branching individuals these little leaves continue on 
each branch. 
Corymb dense, flat or convex; its stiff straight leading 
branches and their pedicels all given off at an angle of 50°-60°. 
Heads large for the plant, nearly 1 in. across; involucre 45; or 
ig in. high, minutely glandular. 
Bracts narrow, somewhat lingual and uniform, reddened on the 
edges, whitish with a distinct narrow green median line but hardly
