Re: Re: perrieri ID's

 I seem to be having a hard time keeping up with e-mail, to much needing to be done outside (SDB Bloomseason). But this is a quick run down on identifying perrieri. There are only a few bearded species that have branching close to the rhizome. I. aphylla is the most notable. I. furcata, and I. babadagica are much like smaller aphyllas and the lumpers place them with aphylla even though their chromosomes are 2n=24. I. perrieri and I. sabina are the other species that branch from the base they have 24 and 40 chromosomes respectively. Although I have hoped to research this further (I hope to develop a key to Iris species as part of the encyclopedia) at present I know of no fool proof way of distinguishing them based on morphology. If one is given their provenance then there is no problem but often the place of origin is lost on garden plants. Generally aphyllas have blue beards and perrieri has a white-yellow-tipped beard as does sabina. To my knowledge there are only a very few of us that have sabina in cultivation so probably you could noy have that. Unfortunately there are aphyllas with white beards also. I often find the bearded species rather exasperating because many of the traits used to distinguish them grade into each other. Please, Tom and anyone else take photos for the encyclopedia. The more information I can assemble the more likely we will be able to pin these things down in the future. My aphyllas this year were ravaged by rain, no good pictures.
