Hey folks, I thought I'd upload some Stylidium debiles photographs, as my first venture into uploading images.... Side viewBefore being triggeredAfter being triggered

Hey Vic,
Surely you must be entirely correct!

I hope so; I grow this easy, little beauty too and don't want to change my label! Cheers Vic

Barry,
Stylidium ISN'T carnivorous? I thought it was protocarnivorous, only evidance of nutrients being absorbed was needed, or have they been shown not to, or is it one of those "guilty of non CP until proven so" type of things I just made up from a court thing.
Anyways.
Very nice S. Debiles! I ordered one, too. Cool trigger!

Hey Sam,
Doug Darnowski would be the person to ask. But my understanding is that some species have stalked mucous glands, and that these glands do have digestive enzymes. But there's no proof yet of absorption of nutrients.
It sounds compelling, but I suppose that proof is probably incomplete. There is also a paper that just came out...I'm scratching my head to remember the details...that weighed against carnivory in Stylidium. Erg, I don't remember the paper, though!

Apparently, Doug will be presenting his research on carnivory and Stylidium at a Joint Congress on Botany & Plant Biology being held in July this year. I stumbled across this link when looking for the recent paper Barry mentions above. According to the abstract, Doug will be discussing radio label studies investigating N absorption. No doubt, our President will enlighten us all, when the time is right, not in advance of publication. www.2007.botanyconference.org/engine/search/index.php?func=detail&aid=18Vic

So how exactly does this trap work? I see the before and after, but what exactly is the trigger? A bug lands on the end and it wraps around?
xvart.

Barry With a great photo like that of S. debile, you'd better bring plenty of film with you for all the species you should see here. Looking forward to wearing out you shutter finger. cheers Phill

I'm really looking forward to it!

Barry, and others:
I'm writing a paper on coevolution of orchids and insects, but came across this today in a book.
In Plant-Pollinator Interactions by Nikolas Waser, there is an interesting discussion of coevolution regarding Stylidiaceae on page 267 and 268

Phissionkorps Good luck with the book, I will be interested to read it when complete. I came across a book called An Enthusiasm for Orchids, Sex and Deception in Plant Evolution. This covers a broad aspect of the orchids adaption to specific insect pollinators centred around the West Australian Orchids. A good read with a couple of pictures of Byblis and Nepenthes included in some very nice orchid and habitat photos. Cheers Phill

well it won't be so much a book as a short (10-12 pages or so) paper critiquing some past studies and offering some of my own insights. I find it hard to believe some of the studies I've come across have been published and continue to be cited, seeing as there is sometimes no replication, or the authors stated something that I think could only be related to their data with a little imagination.

That's called science! It's done in the land of carnivorous plants, too. How many times have we read any of the following: Byblis plants catch birds Nepenthes can capture small monkeys Drosophyllum should only be grown one plant per pot Darlingtonia was first collected by Brackenridge while he was being chased by Native Americans. Anyone else have a favorite, oft-repeated fallacy?
