It is clearly (not so clearly) different from the other
species of Xanthosoma, but it probably has its origins associated
with humans. Should we consider it an artificial species, or should
we consider it as a species that evolved in some kind of mutualistic
relation with the human animal? The same with X. riedelianum, X.
atrovirens and many other species. Even Spathiphyllum wallisii is
not known in the wild. >>aren't many
plants totally unknown in the wild? including pineapple, corn, and
the common hibiscus. <<
Pineapples are certainly known from the wild, the wild
'forms'/species produce MUCH smaller (2" dia.)sour fruit, not as tasty
as the selectivly bred forms that are commercially grown. I grow three
'species' here, beautiful (but spiney!)little things.
I just posted a note about 'wild' maize, and I`m not
sure about hibiscus, but there are vars./species of 'simple' hibiscus which
I`ve been TOLD are the wild forms, one has a basket/pendant
bloom.
To TRY and keep this discussion
Aroid-related, perhaps someone w/ time on their hands here in Florida or in
a warm clime (Eduardo!?!?!?) can plant and observe a rhizome from a
'cultivated' plant of X. sagittifolia---I am told that unless this plant is
'tended', i.e. harvested, re-planted, etc., it stops or slows its producion
of the desirable off-shoot rhizomes and just becomes a GIANT plant that
produces many blooms, in other words it reverts to a 'wild'
state. If even this 'proves' nothing, at least it may show/teach us something about what
the 'wild' plant was like! I have seen these 'wild' Xanthosomas
here in Florida, and they are MUCH larger than the ones you see in
cultivated fields South of the Miami area.
