346 DESCRIPTION OF ASTERS; MACROPHYLLI 
a true green, the lower ones a deep dull green with a cabbage-blue 
tinge. Radical leaves very glutinous in May, little so by the mid- 
dle of June; bracts then already glutinous and overspread with 
small capitate hairs, and beginning to show white margins. 
Inflorescence copious, a widespread convex corymb 6-8 in. 
across in fairly-developed plants, in larger ones becoming high, 
with sharply ascending branches at angle of 50? to 70? ; and heads 
of diverse development, each branch beginning as a reversed 
raceme with long-pedicelled buds down its sides below the terminal 
blossoming head, but later becoming highly irregular by the greater 
lengthening of occasional Md pedicels. 
Heads of moderate size; 3; inch high, 1 or 1% in. broad or 
less. Involucre hemispheric or finally with truncate base, ṣẹ in. 
high. Pedicels long, when dry clavate-thickened to a marked 
degree, when fresh slender, % to 1% in. or even 3 in., nude at the 
base, their subtending bracteals being very small, elliptic-ovate. 
Bracts lingual and nearly alike in size, color and shape, nearly 
all-over greenish when dry, with increased thickness and green at 
the large spatulate green-tip, broadly ciliate all around, coriaceous, 
minutely puberulent except over the broad pale brownish margin. 
Occasional variant bracts are bevel-topped, and a few slightly 
acutish. Upper bracts are apt to show pinkish-purple margins ; 
or often all are purpled throughout. At first flowering (July 1, in 
’97), the 3 chief rows of bracts are nearly equal in length, and the 
outer bracts do not show midrib or green tip, but are increasingly 
thickened and fleshy to the obtuse incurved and somewhat hooded 
apex. 
Rays broad-oblong with rounded apex, 14 to 16, beautiful clear 
lilac, by evening light amethystine, in age more purplish-violet, 
drying nearly blue. Young rays purplish-red, their color seen 
already strong in 1897 by June r9, but not expanding till the 
month following. 
Disks broad and golden, soon full red. 
Pappus extremely long and copious, becoming twice the disk, 
whitish or ecru in growth, rufescent within 3 years after drying. 
Achenes slender-fusiform, brownish, sparsely clothed with weak 
deciduous ascending bristles during growth. 
Viscidity of the copious glandular hairs reaches its extreme 
among Biotian species here, all young and growing surfaces mak- 
ing the fingers sticky and odorous at a touch, such glands remain- 
ing still present though less viscid over nearly the whole stem and 
upper surface of leaves at maturity. 
Odors present include a delicate fragrance from the flowers, a 
bee-bread odor from the disks, and, more conspicuous, a nutty
