Paphiopedilum Cerveranum

[reivilos]

Hello,

Here is my currently blooming Paph Cerveranum.
I hope Frank Cervera is around so that he can confirm this is truly his Cerveranum .

whatever it could be, i want one!

Looks like appletonianum.

I think P. cerveranum is part of the bullenianum complex (Malaysia Archipelago) rather than the appletonianum complex (Indochina area).

As a species "complex", the taxonomy is a mess with lots of local variants that overlap in traits of geographically distant plants. Probably the only way to verify a species in this group is on the basis of known geographic origin.

I think what is amazing is that the appletonianum/bulleniananum flower type (representing a particular pollination strategy) is successfully deployed in such a wide geographic region.

This is a beautiful flower.

Most likely is the variety you have labeled it but your last picture is far from a fully opened flower. Please post a follow up shot of a mature flower to confirm.

You're right. I didn't realized the flower had evolved ever since.
This one was taken today:

I like it!

 

[SlipperFan]

It just gets better and better. The fuzzy edge on the pouch is cool.

Very interesting.

I could not see any of the pictures...

 

[Marc]

Same here, I only see grey warning signs.

Hi, I'm glad you picked it. Here it is.

 

[NYEric]

thanks.

 

[wjs2nd]

Hmmm, cool shape and color. I bet it'll make some very unique crosses.

 

[abax]

Thank you for the thumbnail. I couldn't see the first photos either and was
very disappointed. I think it's beautiful!

Nice, I like these. I have 3 of these bought as amabile, ceramense and celebesence. The leaves show different shape and colour pattern. I think (?) this is different from appletonianum not only in the (finely) hairy staminode but also in the ciliated pouch rim. I picked up this possible difference in Cribb's book on comments about robinsonii which is was described from a cultivated plant. P. robinsonii is now understood to be cerveranum. Cribb suggested a hybrid with hookerae, which now seems unlikely as wild populations have been found in SW Vietnam. However, it is interesting that pouch-rim ciliation also occurs in hookerae but not in appletonianum or bullenianum. In the book "Slipper Orchids of Vietnam" Averyanov,Cribb et. al., I think that some of the numerous in situ pics of appletonianum are actually cerveranum, which Cribb had considered a variety of appletonianum, but they are too small to be sure.

I like it too.
I wish we could all post big photos.....

A nice reminder that "species" is a concept we try to impose on the biological world, not one the biological world must conform to.

Looks like appletonianum.

The name "P. cerveranum" is considered as a synonym of P. appletonianum by Kew.

That is all correct.

The pictures attached in the thumbnail are quite small, I tried to enlarge them but I could not clearly see the staminode, which is unique to P. cerveranum. However, the staminode does look like it has the requisite horn on the staminode that differentiates P. cerveranum and is consistent across the known wild populations. To be sure I would need to see a clear picture of the staminode.
