On pp. 71 and 72 of the current AIS Bulletin, in an article by Tony Huber, I
read the following:
"I. sanguinea was originally produced by a natural cross of I. laevigata (32
chromosomes) X I. ensata (24 chromosomes). All three still grow wild in
Japan. The Sino-Siberian members of the family may have originated from a
natural cross of 28-chromosome sibirica (which in this case provided 28
undivided chromosomes), pollinated by 24-chromosome ensata."
Aside from the chromosome numbers, does anyone know what the evidence is
for these statements? This is an idea that is wholly new to me and one that
I find very surprising.

"I know many children to whom I would fain make a present on some one of
their birthdays, but they are so far gone in the luxury of presents--have
such perfect museums of costly ones--that it would absorb my entire earnings
for a year to buy them something which would not be beneath their notice."
--Henry David Thoreau, Journals, Nov.5, 1855.
