Dypsis canaliculata ?

[Pez]

The biggest argument i've heard as to why the palm being distributed as Dypsis canaliculata isn't really canaliculata is the lack of ramenta on the abaxial side of the leaves. This is described in Palms of Madagascar as "almost continuous ramenta on the midrib" & "many ramenta to 2mm long." I have 2 of these palms and neither had any ramenta under the leaves when I purchased them (thank you Jeff Searl for the wonderful palms). My smaller one is still lacking ramenta, but each new frond on my larger one is showing more and more of this trait. On the contrary, my prestoniana (many people think this canaliculata is another variation of prestoniana) which is close to the same size has absolutely no ramenta. There are many other differences between these 2 palms, but I'll let others chime in.

I was going to post a picture of the ramenta sketch / illustration from POM (page 148) but I wasnt sure how copyrights work. ??

I have both of these here in SoCal. Along with what you said I have noticed this too:

It is less sun tolerant. A little less cold tolerant. It is a little slower. It also has dark green petioles with reddish-brown tomentum towards bottom of emerging spear. Also, look at the pictures of Bo's from his old garden, it looks different bigger too. I am not saying it is or is not another Prestoniana, but if it is then there sure is a lot of variation within this genus too.

Not D. prestoniana, IMO, since when does D. prestoniana have white, and black on the petiole, and a red emerging spear, let alone fine thin pinnae, it's another one of those that have been sold as D. sp. betefaka, I know, I know, it's another D. madagascariensis complex, Ed

In addition, D. canaliculata has not been seen since 1951, and the flower has never been described, see the index at this link for more details, Ed

My D. canaliculata was a Clark purchase that I have been very happy with. Grows very steady, but not quite as trouble free as the bigcurly/prestoniana.

Ed, because POM book says it hasnt been seen since 1951 doesnt mean no one has seen it..Funny how white men claim to be the first or last to see something Im white btw. Bill Beattie made a video of one of his travels to Madagascar called "A little more light". He filmed a group of around 10 individuals in the full blazing sun, these were incredibly healthy and very very stocky, absolutely incredible looking palms, the leaves keyed out to be Canaliculata, but none of these were flowering so nothing concrete.(this was well over 10 tears ago so these would surely be flowering now) The palms Bill filmed are of the same as what is being sold as Canaliculata. As you are very well aware Ed a lot of these Big Dypsis share a lot of similarities but thats very shortsighted for anyone to start lumbering different palms as one. Palms Of Madagascar is of World Class but is well overdue of updating.( is the revised one out yet?) We must all remember and most of us do, is that there is a LOT more Palms In Madagascar than whats in POM. pictured juvenile palm below still lacking ramenta and also has a petiole of 750mm. It will get ramenta and will eventually lack a petiole, this is in full sun as well.

Hi Pete, you mean Western man, don't you? And it's still an sp., as far as I am concerned, Ed

Hi Ed, is it politically incorrect to say white man? You know what point i was making, so many stats and figures taken by weekend warriors, dressed in safari suits while staying in 5star accomadation , and all the information is translated to them by a local who at the end of the day gets a nod of approval and a can of pepsi for his good efforts..Yes Ed its either Canaliculata or an undescribed sp too i think.

Un-ethical is the term, politics has nothing to do with it, but it sure doesn't bother me, as Humanity is over rated to say the least, and I won't extrapolate, I believe everyone here already knows my views, Ed

Guys, we need to stick to the topic, which is an interesting one. I'd rather not have to delete this thread because of a discussion that veers off into unwanted, and controversial, territory. What's "ethical", and not, is a very subjective concept so let's focus on the palm!
