RE: Iris savannarum

 

Rodney,

 

I have seen some many differing numbers cited as to how many Louisiana species Small named.  I have wondered how Small did the deed.   He published photos in Addisonia for one thing.  But I don’t really know the mechanism that would have been used to record the naming of a species.  I notice that giganticaerulea is not on the list you sent, so maybe there are other lists.

Here's that list of Small's irises. I just noticed that 'Shrevei' is on the list. That is obviously not and LA but rather considered a variant of I. virginica.

Interesting discussion on Dr. Small.



A few of tidbits:



The SIGNA check list lists 58 irises named by Small. (It treats all but giganticearulea as cultivars.) I assume these were all the ones he formally described.



As I recall he established a test garden at the NY botanical garden for his LA collections.



There is an literature review on the hexagonae by Philip W. Ogilvie in SIGNA #62. His conclusions (1998) are below.

"Conclusions: The evidence from the literature could be interpreted as supporting only
three species, conservatively: I. hexagona, I. fulva, and I. nelsonii. (According to this
reasoning I. hexagona would in turn be divided into eight subspecies: I. hexagona subsp.
hexagona, I. hexagona subsp. foliosa, I. hexagona subsp. savannarum, I. hexagona subsp.
kimballiae, 1. hexagona subsp. flexicaulis, I. hexagona subsp. rivularis, I. hexagone subsp.
albispiritus, and I. hexagona subsp. giganticaerulea. The literature may, with equal validity,
be understood to be supporting ten species: I. hexagona,I. fulva, I. foliosa, I. savannarum, I.
kimballiae, I. flexicaulis, I. rivularis, I. albispiritus, I. giganticaerulela, and I. nelsonii. Until
adequate field collecting and laboratory testing has been done to clearly demonstrate the
true relationships and levels of differentiation in this group, I believe the second scheme will
lead to less confusion."
