Walking Trees, Parasitic Flowers, and Other Remarkable Plants (mitpress.mit.edu)

One remarkable native parasitic US flower is the Ghost Pipe. It parasitizes the mycorrhizal interface between a fungus and plant. They are uncommon or rare, so I was overjoyed the first time I saw a little stand of them, having read about them years before. I did not pick any (please don’t), but I did want to feel their texture and was surprised to find them firm and waxy, not flimsy like I expected.

If you live near Philadelphia, you can find them under the right conditions in the Wissahickon Valley Park. I hiked there with friends and was shocked by how many we spotted just off trail; they were all over the place!

We have these in Maine too. I’ve always known them as indian pipeweed, although I suspect they aren’t called that anymore as it’s a bit culturally insensitive.


Yeah, I first learned of them under the name Indian Pipe, and a half hour later saw the Ghost Pipe alternative, so ran with that for that very reason. It’s also a more descriptive name, given how they look.


Huh, I had no idea that these are rare; but I know them as Corpse Flowers. I've seen them on numerous hikes here in BC.


> Then there are mangroves whose trunk flattens out at the base; these trees stem from a branch at a low elevation — and they walk!...Is this tree really walking? When we walk, our physical mass moves as a whole. But no displacement of matter occurs with mangroves; the way they grow just makes it look that way. The “movement” is the growing process, four to five meters a year. The branch experiences necrosis and vanishes at one end, while it keeps developing on the other.


This turns out to have been wholly fabricated by tour guides.

Appealing story, though.

BTW, if you like that sort of thing, https://cantrip.org/slow.pdf

Thank you for sharing that. It was a fun read.


I suppose the mangroves walk as much as a glider in Conway's game of life glides.


I was having brain freeze trying to understand what exactly was meant, but this is a brilliant way of putting it.


But not even that much I don't think. But perhaps you are thinking along the lines of a whole forest moving. Trees dying on one side, born on the other. Over a long timescale the forest 'walks'.


How is that different than a horizontal tree growing on one end and rotting on the other?


Well it does say "poetic" in the name of the book, which I own, and I would say "the way they grow just makes it look that way" would definitely poetically count as walking.


Rafflesia is, of course, well known in South-East Asia. But apparently, its name is more well known than what it is. In Singapore, there is a condominium named "Rafflesia" (next to the locally famous education institution, Raffles Institution) and I always wondered how the residents would react to know they are living in a place named after a smelly, parasitic plant. :-)


Anyone interested in learning more about the history and economics of rubber trees and ethnobotany is advised to watch this fantastic Wade Davis YouTube video [0] and I also highly highly recommend the book One River by the same speaker [1].

According to https://en.wikipedia.org/wiki/Hemileia_vastatrix the fungus isn't native to Brazil and mainly parasitizes coffee, not rubber.
