and also by his flowering-time, “Septembri.” Itis confirmed by 
the specimen in Barton’s herbarium so far as it goes. The speci- 
men is an inconclusive fragment, some eight inches of the top of 
a small plant, unlike the curvescentes in the little oval rameals 
borne on its short branches. These, together with its other 
characters, agree with the occasional widely distributed narrow- 
bracted wing-petioled form of A. divaricatus L. with which it is 
here identified. 
16. ASTER DIVARICATUS CYMULOSUS Burgess 
Small plants with dense heads, short broad rays, and shorter 
less pe leaves. 
G. 6 (= PLATE 2), a small N. Y. specimen in hb. Bu., with some lower 
leaves bids as usual at flowering time 
. divaricatus cymulosus — in Br. & Br. Ill. Fl. 3: 357. 1898; as 
follows : 
** Smaller, bearing a single dense corymb about 4 in. broad, or 
several smaller ones ; the branches short, suberect ; acumination 
reduced ; rays short, broad, chiefly 3' — 4’’ long, sometimes 
Stem erect or flexuously assurgent, about 1 or 1% ft. high. 
Leaves serrulate ; or when sharply serrate, the teeth are few, 
coarse and rather straight, not upflung nor couchant. Sinus mod- 
erate or narrow. Inflorescence crowded into a single dense mass ; 
or less frequently compound, its well-separated cymules then 
brought nearly to a level. Bracts with long white terminal cilia- 
tion. Sept.—Oct. 
Differs from typical A. divaricatus L. and from the other varie- 
ties of that species, in its smaller and more dense-clustered heads 
and shorter broader rays. 
Differs from vars. deltoideus and curtifolius in its longer leaf- 
form, with more incurved-acuminate apex; differs also from var. 
alatus in its smaller leaves and less frequent wings ; and from var. 
fontinalis in habitat and lack of radicals as well as the foregoing 
characters. 
Hisrory. The earliest known specimen seems to be that cul- 
tivated by Nees in his botanical garden at Breslau, and preserved 
before 1856, in his herbarium, whence it eventually passed to the
