I didn't find your pix of the hybrid flower, but I'll search|
some more unless you have a handy url.
In this same discussion, the cv "Indian Giant' is brought to
mind. This is a much larger form of S. venosum. Could it be a
tetraploid? Has anyone compared chromosome numbers to the typical,
smaller form? And is this, by the way, any more or less hardier than
the typical form?
And even a bit father afield are the 2 species Dracunculus
vulgaris and Helicodiceros m. The former is found in the western
Mediterranean islands and has a 2N= 28. The latter is found in the
Eastern Medterranean with 2n = 56. Apparently there's no place where
both occur in nature.
Is Helicodiceros derived from a tetraploid ancestor of
Dracunculus vulgaris or do they both share a diploid, and at one time
more wide spread, ancestor? More importantly can they be hybridized
to produce a triploid F1?
Growing these species in close proximity as you do encourages
bee produced hybrids to form. I really enjoy your exploring this
here. More as I give it more thought.
