This is a strikingly showy plant; stem rises gracefully to a height of 5 feet 
often, and is crowned with a cluster of scarlet mottled flowers. 
The lax, scattering arrangement of the leaves is in striking contrast to 
the usually more crowded arrangement in EZ. asperum. Judging from the 
description in Flora of North Am. T. & G. p. 95, I should think its 
nearest affinity would be £. elatum, Nutt. MSS. Still it appears distinct 
from this, all the more probably so, as the only points at which it was 
taken were Camp Grant, Ariz., and Mount Graham, near by, but 5,000 
feet higher, where it had developed some local peculiarities without bring- 
ing it any nearer known species. The stem of the mountain plant was 
more light, airy, leaves smaller and more numerous, and pods longer, but 
with essentially the habit of the same species at the foot of the mountain. 
I am loth to name a new Erysimum, for reasons which are apparent to 
all who have studied the genus. Still, this seems too well marked a species 
to pass it by.
