RE: BRYONET: bryophyte chromosomes


Rod's observations are important.

In fact, assuming few would respond to my comment, I asked R. Rednaz, a
reclusive bryologist who is knowledgeable and occasionally supportive if
he would comment on my note. He wrote me:

"What's the matter with you, Zander? The aneuploids are either mistakes
or will not germinate. The polyploids on the other hand are a great
opportunity for describing cryptic species. I'm going to go through
Fritsch and describe as a new genetically different but morphologically
cryptic species any polyploid that has a geographic distribution
different from the type of the species. Thanks for the tip!"

Well, this was rather stern. On the other hand, Rednaz is assuming that
(1) the polyploids will eventually differentiate as a new species, (2)
they are the same as any molecular DNA cryptic species that may be
distinguished, or if different, then the DNA cryptic species are no
good, and (3) people will let him get away with it.

I think he is correct in number (3).
