Iridaceae seed sources

[John A Gerrath]

I'm really interested in growing some of the wilder members of the 
Iridaceae (the Iris family).  I am looking for four genera in 
particular (all from the southern hemisphere): Isophysis (Tasmanian, 
semi-superior ovary!), and the "bushy" South-African genera Witsenia, 
Nivenia and Klattia (I've only seen these three in pictures, but they 
sort of look like Iris rhizomes tilted up into the air into a shrub-like 
aspect).  Any information about good seed sources that ship to Canada 
would be much appreciated. (I've tried Chiltern's, Plant World, Seederama and 
Banana Tree without success). Thanks in advance.
