In an article, J.A. Savin, wrote, quoting Francis Galton :
"albino orchids ... 'rarely if ever produce albino offspring' "
(J R Coll Physicians Edinb 2002; 32, page 208)
Does this assertion remains true, nowadays ?
under what conditions? when crossed with what? when selfed?
For his part, Kenneth S. Wilson wrote :
"the term ALBINO... It is a word referring to a condition where plant
pigmentation is completely lacking or nearly so
so how musch must be lacking ... 76.44 % 89.12% ... chlorophyll?
anthocyanins? carotenoids?
. There are few albino
plants because it is generally a lethal condition. About as close a
condition as possible to true albinism occurs in the variegated plants or
those that have a saprophytic habit. To say that an orchid flower is an
albino or an albino form is ignoring the fact that the ovary of almost all
orchids is green and that the ovary is still considered a very important
part of any flower."
(American Orchid Society Bulletin, August 1980, p. 867)
Kenneth S. Wilson is an Orchid Judge, not a taxomist, and as far as I
know not a botanist.
I wonder hom often we would have to chew this until everyone understands
that the AOS Judging system is neither a taxonomic or botanic or
linguistic authority.

Do you consider that the flowers depicted in the following photos are
correctly identified (using the terms albina / albino) :
if you look at them and if they are completyl white : yes ... if not: no.
