Dogwood-leaved Aster. 
A very strongly characterized species, with leaves resem- 
bling those of Dogwood. It is one of the most common 
species all through Maryland, where it attains a height of four 
feet. In this vicinity it is very rare, and I have not met with 
it above two feet high. Flowers white, large. In the thickets 
a little west of McMahon’s Garden, and in those four miles 
above the falls of the Schuylkill ; scarce. Perennial. August, 
September.
