How Conifer Seeds Develop
1 day ago
We (formerly Nashaway Trackers) are a group of loosely connected nature lovers who enjoy sharing our observations and discoveries about the fauna and flora of the northeastern US. Most of us are especially interested in mammal tracks and sign, but we also post about birds, insects, plants, etc.
Beautiful and informative. Thanks.
ReplyDeleteI agree! I've seen plenty of the Indian pipes, but will now be on the lookout for pinesaps. That first photo, Lars, makes me wonder if pinesaps are prone to fairy ring formations, my favorite mycological phenomenon.

Susan, that is an interesting observation, because these are not fungi. They are parasitic herbaceous plants, and in the heath family, that which includes blueberries, cranberries,azaleas and various heathers (oddly enough).
ReplyDeleteRing formation occurs in some garden perennials, such as creeping phlox. Maybe the cause is similar whether fungi or herbaceous plants: a tendency to spread out from a nutrient depleted area.
Enlightening as always, Janet. My thought now is that pinesaps might make a good horror film subject - something along the line of "The Attack of the Parasitic Herbaceous Plants." Not quite The Little Shop of Horrors, but ...
ReplyDeleteFunny you should mention Little Shop of Horrors. That film came to mind when I reviewed my swamp azalea photos (posted 7/3/11). The look of the buds gave me the willies (as did Seymour's thirsty plant) -- I almost entitled the post "Audrey III" but worried no one would get the reference. Clearly you would have!
ReplyDeleteActually, these days the saprophytic plants like Indian pipe, pinesap, and pinedrops are placed in their own family, Monotropaceae, which is in the same order (Ericales) as the heath family (Ericaceae). Although I hadn't really noticed it before, it would make some sense for these plants to form fairy rings, because they are invariably connected to fungi underground. It's a sort of mycorrhizal association that (I believe) is unique to this family, in which the plant obtains sugars from other plants through the fungus.
ReplyDeleteIs that true? I read exactly the opposite: formerly in Monotropaceae but now lumped in Ericaceae.
ReplyDeleteHmm... I guess they moved it back again! It also used to be in the Pyrolaceae. Hard to keep track of these things.
