Of this species, collected by Douglas in Upper California, 
we know nothing from personal observation, not having 
met with it in our visit to that country. It is remarkable 
for the almost tomentose pubescence of its leaves, and the 
petioles and young branchlets are said to be velvety; the 
leaflets usually 3, are ovate acuminate, 3-lobed, cleft, and 
serrated. The samara oblong, pubescent, rather shorter 
than the oblique, obovate, and nearly erect wings of the 
seed. 
It appears there is yet a third species of this Genus, 
called by Decandolle, Negundo Mexicanum, which has also 
trifoliate leaves.
