    Just seen a bunch of these on a trip to the Yukon. Absolutely prime time for arctic alpines. Despite rain and snow and hail I catalogued hundreds of species. (And birds!)

    Could this plant also be referred to as “amphiberingian”? (still my new favorite word 🙂 )

    All of the Orobanchaceae are parasitic – either holoparasitic or hemiparasitic. This particular genera (Pedicularis) are all (?)hemiparasitic. The Orobanchaceae are true parasites. They should not be confused with myco-heterotrophs (such as Indian Pipe). The Myco-heterotrophs are ‘interlopers’, taking nutrition from the fungal hyphae that have a symbiotic relationship with trees or shrubs. The myco-heterotroph sneaks into the relationship without giving anything back to the fungus. So as far as the tree knows the fungus is taking and giving. The myco-heterotroph is just there for the ride and ‘pays nothing back’ to either tree or fungus.

      I sometimes wonder about that “pays nothing back” statement…would not be a bit surprised there is some sort of subtle asymmetric mutualism going on that just hasn’t been “unearthed” yet…

    Well, and how many of the hundreds of Pedicularis (or Castilleja) have actually been verified experimentally as hemiparasites? Some have been so documented, but I’ll bet it’s a very small percentage of the total species count. Playing devils-advocate, maybe hemiparasitism is actually uncommon in these genera! The point being, who knows for certain? Heckard’s great greenhouse experiments with perennial Castillejas in the 1960s demonstrated that many (but not all) of the 20 or so species he studied set more seed and grew more vigorously with Helianthus hosts than those without hosts, but other than that, studies have been limited, to say the least.
