Re: HIST:pumila atroviolacea

From: HIPSource@aol.com

<< What is 'pumila atroviolacea?'  Given the history it is surely not a true
 Iris pumila.  Is it instead a form of Iris lutescens ('I. chamaeiris')? >>

My best information is that it is a clone collected by Augustino Todero of 
Italy in 1856. It is listed in the 1939 Checklist as PUMILA ATROVIOLACEA and 
I have read somewhere that it is not known in the wild. I do not grow it 
myself, but Rick Tasco says it phenotypically resembles pumila very closely. 
According to Garden Irises, (Randolph,1959, Appendices D and  E) the 
chromosome count for I. chamaeiris is 40, of Atroviolacea, 36. Counts 
determined for I. pumila L. have been 30 and 32. Also, the hardiness issue 
argues against it being a form of I. lutescens. Hopefully someone will offer 
more potent insights.
