Dear all'
	Just to sort out Mark's Iris miscellany. He mentions a number 
of choice species that fit under a variety of divisions in the genus 

	The Oncocyclus, I sari, is a section of the subgenus that 
includes all bearded iris, subgenus Iris. Likewise the I. lutescens 
in the same subgenus is in a different section, Iris.

	A very different subgenus, Limniris, includes both the 
section Lophiris for all the crested species including the native 
Iris cristata. This species can be extremely variable in the wild and 
numerous color selections and forms have been made-all very lovely.

	The section Limniris also include a wide range of 'beardless' 
irises including 16 distinct series. One of these is the series 
Chinenses which had been poorly represented in cultivation until the 
past few years. The most common species is the very small, I. 
minutoaurea, but it is now possible to purchase I. koreana, I 
odaesanensis, I rossii and others. Also in cultivation but not yet 
commercial is the smaller still I henryi and the larger I 
speculatrix. A varied and fascinating lot.

	Mark's mention of Iris cycloglossa points up yet another 
subgenus Scorpiris, a true bulbous group normally called the Junos.

	Here's a brief chart to put these in perspective:

Genus Iris
	Subgenus Iris (Bearded iris)
		Section Iris	I lutescens
		Section Oncocyclus	I. sari

	Subgenus Limniris (Beardless iris)
		Section Lophiris (Crested Iris incuding I tectorum)
				I. cristata

		Section Limniris (Beardless Iris)
			Series Chinenses	I. koreana
					I. odaesanensis

		Other series include the Louisiana, Siberian, Pacific coast
			natives and many more

	Subgenus Scorpis (Junos)	I. cycloglossa
					I. wilmottiana alba

	Confused yet? Knowing who's who helps to get a better guess 
on how to grow these very distinct species. Thanks for the pictures.
