660. Spirea (Ch.) corymbosa Raf. 1804, 

 precis 1814, Mg. 1812, 1818. Lod. cab. (or 

 sp. glauca Raf.) carpinifolia ? W. SufFruticose 

 quite smooth, stem angular redish, leaves peti- 

 olate ovatoblong acute at both ends, unequaly 

 serrate entire at the base, quite glaucous al- 

 most white beneath, corymb terminal multiflore

 — Alleghanies of Pennsjlv. 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 Sgynous. 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.
