Trillium rivale 'Del Norte'

Does anyone know what the authentic description of Trillium rivale 
'Del Norte'?

The name has turned up in seedlists off and on for many years, but 
without description. I have a dim recollection of being told it was 
originally found by Wayne Roderick in Del Norte county, California, 
distinguished by the petals being pure white and unmarked. However, 
this memory is very dim and uncertain.

Boyd Kline found a trillium on French Hill, in Del Norte country, 
that he believed to be a hybrid between T. rivale and T. ovatum. I 
have been growing F3+ seedlings from this for many years and suspect 
it may be a polyploid T. rivale, rather than a hybrid. Seedlings from 
my stock are being sold by Fraser's Thimble Farms as 'Del Norte' but 
I am not persuaded that this is a correct application of that 
cultivar name.

Google turned up nothing useful.
