  Albino Anchomanes
From: "Michael Pascall" mickpascall at hotmail.com> on 2002.04.22 at 15:34:39(8591)
We have recieved two lots of Anchomanes giganteus from
Bjorn Malkmus . All have grown very well , and I am hoping for a flower on
the largest one later this year.
But , strange things have happened to one plant from the first lot . When it
emerged from its dormancy last September it was all white . It stayed very
small and did not last long at all . I repoted a few months ago and it
re-shot , but albino again !

Michael Pascall,

Dear Michael,

There was a posting on this list some time ago about an Amorphophallus sp.
seedling that did the same thing, then died, so it must happen from time to
time in some aroids. A friend also had it happen in a few Anthurium
seedlings. Maybe something triggers the 'death' of all the chlorophyll for
whatever reason.

The Best,

I've seen this with seedlings of various plants. Some seem more prone to
it than others - I have one albino Manfreda virginica (which has
occasionally been Agave v.) seedling now, a Hippeastrum species seedling
last year was, but I've had a number of albino hemerocallis seedlings.
(One batch was almost 10% albino.)

As expected, they grow perfectly well for a while and then die suddenly -
I assume when all energy available without photosynthesis is exhausted.
The longest lasting for me was the hippeastrum, which was surprising as I
didn't think there was much reserve nutrition in that very thin seed.

I have always wanted to try growing one of these on in sterile conditions
(as with orchid seedlings, or meristemmed plants) - no particular reason,
just to see if I could. But I never have - the logistics seem much more

I don't have any way to know if these are truly albino (achlorophyllous)
or just have greatly reduced levels. There is a fairly commonly grown
variegated form of Hemerocallis fulva, the old orange daylily. Last year I
moved it. This year, where it was, a single shoot has come up that looks
completely white. Every day I expect to see it dead, its root exhausted.
But it has been up for weeks now, and appears to be growing very slowly,
so either I missed a chunk of root the size of a large konjac or it does
have some small amount of chlorophyll.

At last! An aroid topic! I love the ongoing measurement thread, but have
something for this:

A also do hybridizing (strictly amateur) and have come across this in
numerous species: hemerocallis, rosa, dianthus, and lagerstroemeria, off the
top of my heads. One possible hypothesis: I have only had these
difficulties when attempting to cross multi-hybrid parent with multi-hybrid
parent. Attempting to cross hybrid with species or species with species
have never had this occur. I have not as yet attempted to cross any aroids.
All aroids that I have germinated from seed (only 2 so far) have been
strictly species, and no others growing in vicinity that might
