Sorry I got that wrong, they are in Ducampopinus. Which means they are related to Bristlecone pines. So they are still closely related to some 5NP's.
I know, I found that interesting too. Maybe we can call them the "two needle five needle pine"... lol jk.
Vance,
Harold Sasaki has had several at his nursery every time I've been there. I believe his were seedling grown, but they were fairly old with good trunks and plenty of branching. I'll check next time I'm there if you'd like. They were cheap too! I know he also has bristlecone and limber pines.
I have also heard that some of the Colorado guys are collecting them in southern CO. But I've only seen one specimen.
