Preliminary work in 1941 indicates that
V. dobbini is tetraploid. There is considerable
indication that it is an allotetraploid derived
from angustifolium and torreyanum. If one draws
a line around the localities where it is known it
would look as if it were a bona fide species*
Actually, it seems never to have built up 001% than
minor local populations. One therefore cannot says
"distributed from ........to.......instead,
about all one can say is:"Sporadic where the ranges
of aneustifolium and torreyanum share common terri-
tory and where they have been ecologically thrown
together." Actually, as on Long Island, where
aneustifolium and torreyanum have been somewhat
promiscuous, 1 have the feeling that dobbini is
more common than we suspect. The occasional coarser
plants which so often are non-fruiting, might easily
be the allotetraploid. Since most blueberries are
self-sterile, it is only where two individuals arise
close enough together that pollen can be exchanged
that a population would be likely to be built up.
Therefore it is only in rare instances that dobbini
can became”established." The immediate importance of
this material lies in a demonstration of how a poly-
ploid species may arises it does not necessarily have
to have a single origin, it can arise in several or many
places and then with time their ranges could become™
confluent. Or they might never becom^oined. And then
we irould begin to talk about "relic colonies" and
"Tennants of. an ancient distribution." Well, we all do
it—and here is dobbini with a perfectly marvelous set
of disjunct colonies, and "all probably as "new as
yesterday" —that is, relative to the age of the
?ajority of species.
