Susanne , and others in AEG --Since I seem to have provoked more than a
little interest, let me go a bit further, and reduce some of the uncertai=nty
therein.
Let me introduce you all to Dogpile,  metasearch engine (used by librari=ans
to find stuff)  www.Dogpile.com.  If one just types in a word that seems =to
fit what you are hunting for, even a person's name, it will pull up almos=t
everything.  (even one's ex-wife's request for a key to the parking lots =at
Kansas U. Medical Center)  If you don't find what you want, use a differe=nt
search term., either more general or more specific.  Compound words requi=re
bracketing in double apostrophes  e.g.,"botanical garden",   "Bibliothequ=e
Nationale', etc.

.  In this manner I pulled up the Index to Plant Chromosome Numbers
(IPCN)---just type it in---  This takes one to the (Missouri Botanical
Garden Site--MOBOT) where there are about 30 Amorphophallus Chr. numbers
indexed,  about 40 Arisaema species numbers, indeed almost all plant gene=ra
that I have ever heard of., specified as to the source of the plant, and =in
some cases, particular clones of each. .   It might take an hour to go
through the aroids.  n=12,13,14, etc.

I did not fully realize that I had not introduced myself, since I thou=ght
I had done something like that when I applied to join the AEG  (senior
moments).  I am a retired clinical psychologist with a long-time interest=in
plants, hybridization,evolutionary biology, oncocyclus irises, conservati=on
of a number of things,  I collect figural milk glass, pressed glass
candlesticks, , have a mildly strange Shiba Inu (dog) with two surgically
renovated knees. Am married,   have some grown kids.  Wife has a horse (P=aso
Fino).  I'm trhing to learn about Arisaemas.  Have about a dozen and don'=t
know whether they've survived the winter yet.  A few arums.

Re conservation.  Am fully familiar with the extincton of a number of for=ms,
re irises, some may exist only in captivity like a few animals in zoos.
Have no hesitation inn trying to maintain genes of some specices in hybri=d
form if that is the only way to do it, especially where the provenances f=or
some species are being paved over, or destroyed to make way for orchards,=or
aqueducts, or whatever.
