124 DESCRIPTION OF AsTERS; DIVARICATI 
KK KK GG EX DTNEXPTAINED. INFLORESCENCE-VARIANTS ; 
forms not due to immediate environment, and having 
some strong peculiarity in the inflorescence. 
! Bgoap-RAY form. Plants with broad, short, dark, coarse- 
toothed leaves, broadly divaricate inflorescence, and broad heads 
with unusually broad rays and bract-tips, the latter mostly abruptly 
truncate. Rays about 7, over % in. broad. 
N. Y. vic., Bryn Mawr, Se. 6,’99, on Palmer Rocks. 
1? 'THREE-RAY form. Peculiar plants with few large thin 
smooth dark-green leaves, an attenuately forked inflorescence 
with many large lanceolate bracteals ; and very imperfect heads 
occasionally of 6 rays but usually with about 3 long rays and the 
others wholly or partly abortive. Leaf-form oblong-cordate, in- 
curved-acuminate, with very large broad brace-base, the upper 
truncate, the axiles lance-oblong, tapering almost equally to the 
sessile base. Otherwise the petioles are very long and slender. 
N. Y., Kaatersksll Min., Se. 7, ’99, in shade. 
* Five-ray form ; a small little-leaved form with small heads 
chiefly 5-rayed ; the first head of each branchlet bears 6, the one 
or two lateral heads 5. Plants cespitose, 114 ft. high, glabrate. 
Leaves thin, apt to be continuously petioled. Rays oblong, 
blunt at the minutely three-toothed apex. 
Ms., Zaconics at Sky Farm, Se. 5, 1903. 
* CANALICULATE form. Rays horizontal, linear-canaliculate, 
their sides being early and continuously upcurved. Leaves thin, 
sinus and petiole continuing well up to the loose inflorescence. 
Bracteals rather large, ovate-acute. Bracts very abruptly trun- 
cate or bevel-topped, broad and short, thin along the pale edges, 
thickened along the middle and the short dark tip. Stem apt to 
be pale m 2 ft. or less, and zigzag.

— Many other oca of the Divaricati and Macrophylli occa- 
sionally lose the flatness of the rays with age, the margins becom- 
ing upraised; but in this present form the canaliculate stage is 
the principal one, the rays remaining flat for scarce any time, per- 
haps from greater delicacy of their thin texture. 
1? Cupreous form. Rays persistently change from dull-white 
to coppery-red year after year. Stem strong, greenish, highly 
zigzag, about 2 ft. ; branches stiff, wide spreading ; bracts highly 
ciliate, mostly truncated obtuse, as in A. divaricatus type. Leaves 
(except in larger size, earlier growth and deeper color) like those 
of the Russet-tuft form, with which it grows and from which it
