140 DESCRIPTION OF AsrERS; DIVARICATI 
Becomes the prevailing form of the Divaricati in many sandy 
localities on approaching the sea. The stem-leaves curl involutely 
in continued dry weather, and the plants almost disappear entirely 
in prolonged drought.

while nearest to the typical 4. arenicola still verge toward normal 4. divaricatus L., as 
probably do all je growing so far inland as Albany.

4. Aster persaliens sp. nov. 
Virgate small-flowered plants of deep shade, with thin taper- 
based lance-like hack-edged leaves, stiff bevel-tipped bracts (acuter 
on central heads), maroon disks and flat-bunch inflorescence ; the 
couchant teeth very sharp and salient oh the name).

* My first observed specimens of this very distinct Aster, D. C., '87 and '88, were 
from Rock Cr., and in Va. opposite, then recorded as ** Tiai vo. with 
variants as ** A. corymbosus, intermediate form A," and A. corymbosus X A.—. 
Further scrutiny so impresses me with the distinctness and permanence of 4. paccm 
that I feel it misleading to continue it as a subspecies.
