660. Spirea (Ch.) corymbosa Raf. 1804, 
precis 1814, Mg. 1812, 1818. Lod. cab. (or 
sp. glauca Raf.) carpinifolia ? W. Suffrutieose 
quite smooth, stem angular redish, leaves peti- 
olate ovatoblong acute at both ends, unequaly 
serrate entire at the base, quite glaucous al-

— Alleghanies of Pennsylv. Maryland and Vir- 
ginia on dry ridges, stems pedal often annual 
leaves 1 or 2 inches long, nerves prominent be- 
neath, flowers white in large multiflore corymbs 
with 1 to 3 small ovate entire leaves, flowers 
nearly level large, stamens long. By a mis- 
print I stated this sp. to be trigynous in my pre- 
cis 1815, it is 5gynous. I discovered this plant 
in 1804 and communicated it to Muhlenberg. 
Sp. glauca would be a better name as there are 
so many corymbose kinds.
