126 DESCRIPTION OF ASTERS; DIVARICATI 
star the more because the small and pale whitish-yellow disks do 
not change to purple and blend in color with the rays. Leaves 
uniform, short, roughish, dull deep green, with broad brace-bases ; 
veins much darker than the leaf. Inflorescence of few scattered 
heads ; or of more; diffuse, and on long filiform pedicels often 34 
in. long. Bracts narrow, long, obtuse, chiefly with broad white 
scarious-frilled margins; ciliation and tip moderate. Surculi 
yellow or almost orange.

1? PURPLE-PAPPUS state; pappus purplish or deep vinous- 
Wert (in herbarium) instead of ferruginous or salmon-red, as is 
usual. Leaves very smooth and thin; otherwise nearly normal.

1? LoosE-FLOWERED form; plants in sunlight, where any 
explanation of the diffuse pedicels as due to reaching after light is 
disproved by the presence of close-flowered plants in the same 
patch amid the same conditions and equally mature.

PARU: L., but with conspicuous g growth of Mitchellian bracteals, 
1. €., bracteals resembling leaves of Mitchella repens in size and shape, 
i. ¢., the normally ovate-acute bracteals fail to develop their apical 
portion, about one third of the leaf, and become oval with obtuse or 
rounded apex, and remain subentire. Occasionally plants with both 
kinds of bracteals are found ; but generally only one kind is pro- 
duced on a plant and all plants from the same rootstocks are alike, 
while plants otherwise similar and growing within a foot or two 
produce the normal bracteals. Similar Mitchellian bracteals are 
occasionally developed in other varieties, and in beautiful profusion 
by A. divaricatus deltoideus. They are commonly darker, firmer 
and of richer tissue than the normal acute bracteals, and more con- 
spicuous though hardly half the size. I have not been able how- 
ever to prove them developed a second year from the same root- 
stock. It is doubtful if they are properly cases of arrested 
development. They seem never to occur on plants of the Mixed-
