182 DESCRIPTION OF ASTER; DIVARICATI 
Bracts thin, obtuse-chanfer, and oblong or almost lingual and 
roundish at apex, with rather strong ciliation and 2 whitish 
scarious margins. Green tip thin and broad or absen 
Rays rather narrow, about 10 or I2, linear- Jes with the 
sharp or truncate apex nearly equally divided into 2 or 3 small 
blunt teeth. Disk flowers numerous, soon deep crimson, with 
broad bell, deep narrow widespread lobes, and slender threadlike 
stalk, the stalk sometimes three times the bell in length, sometimes 
but just equal. Achenes slender, fusiform, the minute hair gen- 
erally absent from the striae at maturity. 
— The foregoing typical form is very distinct from other 
species ; than carmesinus and argillarius and other small species 
it is much sharper-toothed : than wirgularis, stilettiformis and other 
sharp-toothed species, its leaves are much rounder. 
Habitat, forming loose patches, either in half-grassy or nearly 
bare situations, in thin soil, over gneissic or slaty rocks or among 
stones derived from them. Mass. to Va
