Hi David,
I have no expertise with Trillium. I agree it is confusing. 
I looked at CalFlora for T. chloropetalum…
and for T. angustipetalum…
and I looked on google maps for where Redwood National Park overlaps with the distribution maps on the CalFlora pages. Looking at the 'Distribution Grid' more detailed view, I see T. chloropetalum is more coastal and T. angustipetalum more montane.
Based on those items alone, I would have concluded T. chloropetalum could be found in Redwood National Park, as well as T. angustipetalum. 
So I expect CalFlora is just not as up to date as some other resource. 
Perhaps the answer is that a photograph and a map are not sufficient for ID?
