What do intentional hybrids of the two species look like, i.e. the repute=d
parents, serratum and tosaense? Do they look like typical A. ehimense? Th=is
would seem to be a case in which DNA analysis could solve the controversy
very handily. Is that in the works so far as anyone knows?

It should be noted that not everyone agrees that Ariaseama ehimense is a
hybrid of A. serratum and A. tosaense.  From what I have seen in nature
in Shikoku, in Ehime, the two alleged parents are not both present where
A. ehimense is abundant, and in any case do not overlap in bloom, with
tosaense flowering much later than serratum.  It is also hard to explain
the origin of the black spadix seen in many individuals of A. ehimense,
as the two supposed parents in the region do not show that
characteristic.
