ASTER VIRIDIS 137 
nearly orbicular, 1 to 2 in. in diameter.—All the above characters 
seem derived from A. macrophyllus. 
Stems I or 1% ft. high, brownish, smooth and glabrous, 
slightly flexuous, brittle, forking above into a wide loose inflores- 
cence with slender divergent branches and irregularly corymbose 
top, the whole often 8 in. broad and 6 in. deep. Caulines small, 
8 or so occurring below the similar axiles, about 2 x 1 in., ovate- 
triangular, low-serrate, acute with narrow sinus and short slender 
petiole. Upper axiles soon show short wings and then become 
abruptly sessile.— Characters allied to A. divaricatus. 
Rameals of two types, oblong-acute and serrulate, derivable 
from the norm of A. divaricatus; and oblong-rhomboid, obtuse 
and crenate, derivable by prolongation from the oval Mitchellian 
rameals also produced on A. divaricatus. Both types may exist 
together on the same plants, either one being predominant and the 
other reduced to a few exam 
Head 1 in. broad or slightly less, resembling A. divaricatus ex- 
cept that most bracts are thinner, narrower and sharper; but 
thicker than in A. Schreberi ; a many sore are as rigid and as 
blunt and almost as ciliate as in A. divaric 
Differs from A. owed fentinali posee in its rameals, 
bracts, its larger coarser radicals and in the presence of many gro- 
tesque flowing teeth

success in finding other examples since writing the above, leaves the para E of its 
hybrid origin unchanged. 
Habitat, especially: in sandy and gravelly roadsides in deep 
loose soil toward ditches, in full sun, forming small scattered 
clumps.
