106 DESCRIPTION OF ASTERS; DIVARICATI 
Rays linear, slightly narrowed at the ends, about 1 in. long, 
often 1 as broad. 
Disk- flowers often about 25, their lobes cut about halfway 
down the body, which is broad funnel-form, tapering into a stout, 
pale greenish tube. The tube expands slightly at its base, and is 
about 2 the length of the disk-flower. 
mip yellowish-white in bud, then white, becoming dingy 
after flowering and slightly tawny in the herbarium within a year, 
often reddening finally ; seen a fine salmon-red in 10 years, and 
still deeper in 20. 
Receptacles convex, alveolate, the socket of each flower stel- 
lated with a sharply 5-pointed membrane. Each alveolus rises in 
its center into a hollow conical tubercle or foveolus on which the 
achene stands 
Involucre usually but faintly triseriate-chequered from the 
green tips. 
Bracts with their sides whitish (in the middle and inner bracts) 
the narrow midrib distinctly precurrent, greenish or brownish, and 
slightly clustered, inner bracts often without any green. 
Internodes lengthen greatly during flowering, changing the 
aspect totally. The inflorescence is prominently bracteate in the 
bud, the subglobose young buds often remaining for some time in 
sessile clusters among their triangular- ovate bracteals, suggesting 
little Carpinus bracts (July 11-25, in W. N. Y., etc.). 
Development ; as noted about Washington; D.C, 1 in. high, 
3 leaves unfolded, Apr. 17; on May 17, 15 in. high, 7 leaves 
full grown, one of them already dead; on July 17, near Dunkirk, 
N. Y., same height and number of leaves but with the flower-buds 
becoming distinct. 
In full flower, Dunkirk, N. Y., at 500 ft. elevation, and 
Taconic Mts. at 1,600 ft., last week of Aug. and first week of 
Sept. ; vic. N. Y., Sept., into first week of Oct.; Washington, D. 
C., last week of Aug. through Oct. 
Some flowers remain till frost, especially from sprouts ; late 
flowers collected about N. Y., Nov. 3, 5, 8; about D. C., Nov. 8. 
Young radicals about N. Y. have been found to reach $ in 
long by Apr. 12, 21 in. by Apr. 25.
