David and List Members,

I got a shipment of the mystery Irids a few days ago from Donald (thanks
again Don) so let me give you an update on their description.

They have thin lancolet leaves, like a Siberian, up to approx 24" in length
by 3/8" in width at their base; the pink rhizome is in fact a stoloniferious
stem, which travels sub-surface, that appears to be one form of propogation
for the plant and is approx 1/5" in diam, with new leaf sheaths (shoots),
earlier described as orange bands (old sheaths), every 1"; the roots are
thin and branching from the base of the fan, my largest had 9 leaves.

Nothing about this plant reminds me of I. pseudacorus except for the color
in the stolon which does not resemble a rhizome at all.  I will be taking
one of the plants with me to the Missouri Botanical Garden today so maybe
they can shed some light on its ID.
