I would like to know if anybody knows where to find these species :
* Aspidistra sp (Convallariaceae)
You can probably find it at any large houseplant company if you spell it
correctly.

According my sources (Rudall & Campbell, Flora (1999) 194, 201-214),
this is the correct spelling. I do not care the species level.
Houseplant usually don't propose such species. They only sell common
commercial ones.

Iris reticulata and Iris danfordiae are commonly sold by bulb companies. You
will probably have to look harder for the others.

That's why I am asking on this newsgroup. It would be possible for
Asparagales-specialized botanical gardens or private collectors.

Iris,
Central NY, Zone 5a, Sunset Zone 40

Do you have a mail adress from this company ? Do they have a web page
? Do they send outside USA and have they the abilitation to make
phytosanitary certificates ?

Cordially,
