PLATE LIX. 
Te Prickly Ash is a shrub of middling 
height, found in woods and moist or shady decliv- 
ities in the Northern, Middle and Western states, 
It is rare in Massachusetts and the states north 
of it, its localities being very circumscribed. 
After I had taken pains to procure specimens 
from Connecticut, I accidentally discovered a 
thicket of the shrubs in a wood in — six 
miles from Boston. 
Late botanists have placed the genus Xan- 
thoxylum in Pentandria Pentagynia, although it 
is dicecious, or rather polygamous. Its calya is 
inferior, five parted ; corolla none ; capsules from 
three to five, one seceded. The X. fraxineum is 
prickly, the leaves pinnate ; leafets ovate, suben- 
lire, sessile, equal at base ; umbels axillary.
