Icones,
I'm a hobbyist orchid grower, not a botanist, but based upon a talk one
well-respected speaker gave to our orchid society several years ago, my
understanding is that some 'alba' orchids with suppressed anthocyanin
(red or purple) and flavonoid (yellow) pigmentation can still appear
greenish due to the inheritance and distribution of chlorophyll within
the plant, including the flowers. Can any of our resident taxonomists
and botanists confirm or deny this understanding?
Marc,
After I got off the computer I went and looked at my set of the Japan
Orchid
Growers Association's Register of Awards. Admittedly my set is
incomplete
(missing 7 issues) but I was able to locate one Laelia (Sophronitis or
Hadrolaelia if you prefer) tenebrosa alba listed. However in looking
at the
photograph it just shows an aurea form. There are two types of aurea
forms,
one with the color of the lip the same as in the type, and then ones
with
pure white lips. There are clones that are green instead of yellow,
but I
would never call any of these alba.
