Hello,
There is major difficulties concerning Ipomoea carnea subspecies
fistulosa and Ipomoea carnea subspecies carnea.
I had researched the supposed differences in the 'subspecies some years ago
and found that there were significant misconceptions involved regarding the
structure,location and behavior of the 2 supposed subspecies.
The only difference is in the shape (measurement parameters) of the leaves
and plants conforming to the leaf parameters can be found in populations
supposedly consisting of only 1 subspecies.
There are studies that indicate that other aspects like more vining or
trailing habit for subspecies carnea has been shown to be dubious at best.
The fact that both subspecies were found to be able to adapt and therefore
inhabit both arid and wet areas in both the New and Old world tropics has
been shown to be true and that both subspecies can exhibit upright or more
of a trailing (vining) habit based on topographical setting and adaptation,
not any feature that is hard-coded into the genetics.
The information on the web from official sites concerning the subspecies is
mostly related to subspecies fistulosa because that is what supports the
old , antiquated studies...subspecies carnea is rarely located on the web ,
not because it is any rarer than fistulosa but because it doesn't fit the
old studies...
There is no difference in the seed characteristics of subspecies fistulosa
or subspecies carnea.
The supposed differences were based on early studies that utilized
under-sampling and did not embrace a wide enough area of topography.
I used to have all of the most important studies on my old hard drive but
hardware self-destructed...although some of the more revealing studies were
conducted in India (!)
The USDA and others responsible for perpetuating the myths related to the
'subspecies' will not back off without losing face and political agendas
may apply...some co-author papers with Monsanto ( major chemical company
that manufactures / sells most of the herbicides to fight invasive exotic
plants, and as the list of invasive grows , so does the amount of toxic
chemicals used to combat 'invaders') ...my position is that the herbicides
used do more long term damage to ecosystems than the over-growth of any
plant species...enough said...
I would like to go on permanent record regarding my position on the myths
related to the Ipomoea carnea subspecies and that the *only* difference is
a relatively minor leaf measurement parameter and no other physical or
behavioral characteristic.
regards,
Ron
