I take Delavay’s plant to be intermediate between the two 
varieties. Forrest No. 5546 is a tree; Delavay No. 3725 is a 
shrub ; Forrest No. 5835 is a dwarf shrub. The leaves of the 
series differ much in size and in shape, but are much alike in 
consistency, in the arrangement of the lateral veins, and in the 
silky hairs which are specially prominent on the under side of the 
veins. The bracts and nutlets are very similar.
