Lookie what they've found

Quoting:
ANTANANARIVO, Madagascar — A self-destructing palm tree that flowers once every 100 years and then dies has been discovered on the Indian Ocean island of Madagascar, botanists said Thursday.

The name of the giant palm and its remarkable life cycle will be detailed in a study by Kew Gardens scientists in the Botanical Journal of the Linnean Society published Thursday.

"It's spectacular. It does not flower for maybe 100 years and when it's like this it can be mistaken for other types of palm," said Mijoro Rakotoarinivo, who works for the London botanical gardens in Madagascar.

"But then a large shoot, a bit like an asparagus, grows out of the top of the tree and starts to spread. You get something that looks a bit like a Christmas tree growing out of the top of the palm," he said.

The branches of this shoot then become covered in hundreds of tiny white flowers that ooze with nectar, attracting insects and birds.

But the effort of flowering and fruiting depletes the tree so much that within a few months it collapses and dies, said botanist Dr. John Dransfield, author of the study.

Dransfield noted that "even for Madagascar this is a stupendous palm and an astonishing discovery."

Sound like another kind of plant. Sends a shoot high into the air and then, when it's finished blooming, dies. An agave of some kind, I think?

It's a new monocarpic palm. Someone also posted a similar thread on gardenweb (here: http://forums2.gardenweb.com/forums/load/trees/msg0123095814782.html ) which has a bit more info, and there's more here, with photos: http://www.kew.org/scihort/news/new_palm_genus.html

Really great article you found from Kew.

I was poking around and found this-

That is absolutely amazing! I'm looking out my window at my white pines that are over 60' tall, and imagining a flowering palm of that size. Thanks for the links, and so grateful that one had photos.

E-lib, will now be trying to figure out how to get seeds and grow it for herself. Let us know how it turns out.

Won't be easy to get seeds - with only 100 trees, and if they live 100 years before flowering, that means on average, one palm flowering each year. As palms are usually dioecious, the chances of an individual getting pollinated and producing viable fruit are very low.

If it does happen, someone is going to have to be on hand to collect the ripe fruit, and sow the lot for local outplanting - if not, the species will be extinct in short order.

They'll also have to think about collecting pollen from flowering males for storage until a female plant flowers, and do some deliberate cross-pollinating (should be feasible, this is done a lot in commercial Date Palm orchards to increase fruit production).

I was mostly just kidding about Equilibrium searching for seeds. She does love a challenge when it comes to sprouting trees. She also really loves her tropicals! ☺

Guessed as much, but I thought it was interesting to speculate on just what dire straits this palm is likely to be in. I fear it won't be at all easy to get it to escape extinction. Tho' the Kew article does mention options on selling seed for ex-situ conservation.

Although I have an appreciation for this find, that's not my type of plant. I truly gravitate toward the natives. No way no how could I even dream of handling any plant that could attain those heights inside my home and my greenhouse is only 10' tall so that's out. I do hope their conservation efforts are successful though.

I personally give this Palm the "Darwin Award". This is survival of the least fittest and least probable to survive.

I think the species would normally be fine - it's just when 95% of its habitat is destroyed by man, it becomes particularly vulnerable by drastic reduction in pollination opportunities.
