ASTER DIVARICATUS 125 
may be a derivative. Disks deep red-brown in nature, deep crim- 
son in drying. Copper-color in the rays appears in about a week 
after expanding, and remains two or three weeks, when the rays 
become marcescent ; and even in this shrivelled state they retain 
much of the copper-red color. — For color comparison, see also

joining similarly shaped leaves of the Russet-tuft form, and of typical 4. divaricatus. In 
O days 26, the red had faded entirely from these leaves above and was dis- 
appearing beneath; the leaves were now full grown, 2 and 2% in. long, with broad 
excavated sinus, For seven years that this group was under observation it maintained 
its characters exactly, standing out year after year with copper-colored heads though 
surrounded with white ones. After ei iat in 1903 most of the colony died, espe- 
cially the central cupreous plants; only one or two sprouts from the cupreous form 
came up in 1904 (and again sen hm feeble and faintly cupreous inflorescence. 
5 WHITE-DISK form, with disks whitish or after drying pale 
cream-color. Stem very dark plum-color, flexed, slender, 12 to 
15 in. Leaves long, dull dark green, firm, dense, opaque, 
smoothish. Leaf-form oblong-lanceolate, the 4 or 5 lower ones 
so, abruptly rounding into a broad shallow sinus, the small close 
teeth continuing upon the long acumination. Other leaves oblong- 
elliptic or lance- elliptic. Narrow petioles continue into the inflor- 
escence, quickly diminishing, the lowest ones 1 inch long, most 
others only 1 or Lin. Leaves serrulate, subrugose beneath while 
fresh, not so when dry. Inflorescence small, few-flowered, about 
IO divaricated heads on capillary pos + to $ in. long, with 
linear bractlets. Heads very small, 4 iin. high, £ in. broad or less ; 
disks finally turn a dingy pale brown. Rays 6, sometimes " 
oblong, milk-white ; pappus very white. Bracts uniform, smooth- 
backed, rounded at apex, white-ciliate all around, with a dark 
definite crescentic tip; the inner ones pale, scarious, without 
green
