the under surface of the leaves was pink-red in life. In 
the dried specimen, it has changed to a rich golden rust- 
color. It is probable that the finest of the stellate hairs 
(that is, those on the blade itself) were, in life, whitish 
as they are in the dried material and that the coarser 
stellate hairs along the primary, secondary and tertiary 
nerves (now rust-colored, but in places still pinkish) were 
responsible for the general hue of redness. The specific 
epithet refers to this beautiful character of the under 
surface of the leaf.
