Suicide trees of the world

So this feeling of liking trees better than people probably has a lot to do with social dissatisfactions springing from the unsavoury things being done to and with trees that I come across at my job. A lot of it probably also has something to do with getting really high and watching The Private Life of Plants and thinking it was just the coolest thing ever. (Still do.) A lot more of it also has to do with growing up with a surfeit of trees and a deficit of people, while presently living in a situation with a deficit of trees and a surfeit of people.

(Almost funny story: a couple of nights ago, we were walking home and I - ever a pleasure to live with - was maintaining an unbroken stream of profanities about stupid Belgian wankers, et cetera, incapable of all of the fundaments of livable civilized organization, et cetera, plus the weather sucks . . . on the last stretch, the F-word broke in to request I shut up so we could concentrate on enjoying the evening air. I obliged, but almost without missing a beat a guy ten feet in front of us started being violently, noisily, extendedly sick on the pavement, and a yelling drunk chick thirty feet in front of us started leaning on her car horn. Neither stopped until after the arrival home. Nearly a moment of win, except it was really disgusting and annoying.)

Anyways, wherever the liking-trees-better-than-people has come from, obviously it's made me quite interested in trees, and the more I find out the more interested I'm getting. They are so fucking cool and their reproductive strategies are mind-blowing - or rather, their life cycles are mind-blowing, in the sense that time and mortality to a tree mean something completely different than what time and mortality mean to an animal, that is to us.

I guess the most remarkable example, because of the way these different conceptions of time and mortality intercept with a homonym, is the suicide tree. Say it to some people, and they'll think of the cerbera odollam, an Indian/Malagasy swampy tree, used as an ornamental, whose kernels have been used countless thousands of times to stop the beating of otherwise healthy human hearts in some of the most crowded and impoverished parts of the planet, where our race's life has been, as a generality, fruitful and yet horrendously, unignorably short. And yet not short enough for some. (That having been said there are an awful lot of them in Kerala, which is a remarkable place.)

Say it to others and they'll think of the tachigali versicolor, a central American jungle-y rainforest-y tree that lives to be about a hundred years old, grows to about 50 meters tall, flowers once, and then dies. The thinking goes that the gap it creates in the forest canopy by its death benefits its saplings by letting them get a little more light than they would otherwise, and that the benefit of releasing seeds so seldom (the species has a seeding event every five years or so) is that predators are rather less likely to eat them or the saplings: flowering, seeding and sprouting so intermittently, they would never be a primary food source that predators would learn or evolve to rely on.
