Re: Re:Iris brevicaulis Ontario

The color of this Ontario brevicaulis is interesting.  It seems to have much more red in it than brevicaulis I have seen from the South, which are almost all in the blue and lavender range.  There was a possible brevicaulis documented in Northen Ohio that seems to have that same color trait.  http://www.ohionatureblog.com/2009/06/its-always-nice-to-find-what-youre.html  Perhaps it is a regional variation, and perhaps there has been some past introgression with I. fulva.

Being doing some research. Found original article. It was in
University's archives , so will be a few days for them to dig it out.

Here is a photo courtesy of P. Allen Woodliffe, who was involved in
Ministry of Natural Resources. Apparently there were originally about
10 populations, but may only be two left in conservation areas. R est
replaced by development. Located on Pele Island, south of Point Pele
in Ontario. This is the most southerly part of Ontario, same latitude
as North California.


Close up of flower does show the signal bristles. But I also saw some
on by blowups of I versicolour, but quite a bit smaller. Currently no
photos of stem. Still tracking down a herbarium specimen.

I just may be able to get a plant. I'll be working on it. The genetics
of this plant will have an interesting tale to tell. If a true
brevicalus, it may be part of a relic population with information on
migration route of the Louisiana iris.

.Allen gave permission for his photos to be posted on SIGNA, if there
is an interest.
