Re: HYB: Louisa's Song/umbrata

I like "corona"!  Captures the part that I like, which is the light rim.

I read somewhere recently (one of the recent Bulletin articles?) that
<all> of the pigment in the petal is contained in the surface layer of
cells.  So it's not clear to me how there could be a physical overlay of
color.

Neil said:
<Adam, the "Umbrata" concept is still fluid.  Fred Kerr prefers to call
this phenomenon a "Corona" which is rather appealing.

As I understand "Umbrata", it refers to the fall surface overlay of dark
color  (and texture, probably), which usually leaves a relatively narrow
band of the underlying color showing--as in   LOUISA'S SONG .>
