I guess this is skeptic in me, however, has anyone done transplant
experiments to see if its an environmental thing! I'm still trying figure
out the rationale for venosa and purpurea distinction. I've seen purpurea
purpurea that look like "venosa", fuzzy, large wavy hoods etc growing in
multitutudes in Northern Ontario, and I've seen what most would call "ssp
purpurea, growing in the carolinas. Other field types have also made the
same observations. However, I would agree about the burkii, it is
morphogically very different from other purps.
Another interesting example is the var ripicola designation that was once
used to describe the Marl Bog form of purpurea. These plants are extremely
different from typical purps, very small, brittle deep red leaves, with the
whole plant not bigger than a man's fist! However, pull one out and plant
it in a typical sphagnum bog habitat, and voila! You have a typical
purpurea in a couple of years.
I suppose as human's we have this insane urge to classify things, maybe
instead of splitting hairs on purpureas maybe we should work on some of the
more obvious plants that deserve status, ie all the green "albino" forms of
Sarrs. S. purpurea f. heterophylla is formally recognized, where is S.
rubra jonesii f. heterophylla, S. psittacina f. heterophylla, S.
leucophylla f. heterophylla etc etc etc.
While I'm on this thought, how about all the alatas, people are splitting
hairs on purps when alata is more variable than any other sarr!, and yet,
no ssp, no var's, no formas or anthing of the like.
Is anyone planning on giving formal status to the rubras of western
Georgia, that we all affectionally call Ancestral? What about the mountain
form of flava that occurs in a number North Carolina mountain bogs?
Maybe I should write a paper ;-)
