A common shrub in the drier mountains and arroyos, especially in the southern 
part of the State, where it is a valuable forage plant much browsed by cattle, sheep, 
and goats. It is well worth cultivation for decorative purposes since it grows rapidly 
and produces an abundance of white flowers as large as apple blossoms, while the 
clusters of plumose fruits, first greenish and later reddish tinged, which remain on 
the plant for some time, are almost as beautiful as the flowers. 
The type of F. paradora acuminata was collected on the mesa near Las Cruces and 
that of F. micrantha is from the same locality. 
The native name is ‘‘pofiil.’”’
