Re:RE: hybrids

>>I suspect that the odd Echinodorus Marble Queens are simply a partial
reversion closer to the 'normal' genetic traits of the regular species
(genetic drift again.) Sports often 'revert' to wild types if the genetic
trait that we find so admirable is not adaptive to the plant. Variegation is
particularly susceptible to this, since the white (or cream) parts are from
a lack of chlorophyl in that area. Without the extra photosynthes those
blank areas would normally provide, the plant may not be as well adapted and
start producing leaves with more green. As plantlets, the ones with the most
green are likely to grow faster than the others. All green ones will
probably be culled, but others that show less than normal may be included,
especially if the nursery needs to fill its quota of plants from a
relatively short supply. Variegation is the worst about this but as anyone
following the threads on red leaved forms can see other traits tend not to
be as fixed as we would like<<

So are all varigated plants hybrids either by man or by nature? Are stem
plants hybridized as well? Maybe someone can tell me if these plants, not as
commonly available as others are hybrids or not, as I am bringing many of
these into my inventory in the next month:

varigated mexican oakleaf, trichocoronis rivularis variegatus
varigated bacopa
varigated Hygrophila difformis
Rotala macrandra varigated
R. roundifolia "indica"
Ludwigia inclinata
"Dwarf" lobelia cardinalis
Hygrophila rosannervis
Gymnocoronis spilanthoides varigated
Barclaya longifolia "red form" (red on both sides)
Alternanthera reineckii rosaefolia
Alternanthera 'red bound' one of the "blacklisted"?
How about Nymphaea?
zenkeri 'green'
zenkeri 'red'
Nymphaea rubra
