Horny Phrag. manzurii?

[eteson]

First bloom of this schlimii. This is close in coloration to manzurii but look at the staminode...It is horny and not rounded as the manzurii plant described by Higgins et al.

I am not sure if horny is the word i am trying to use... i want to mean "with horns"

Hybrid?

 

[eteson]

Plant collected in the wild. Far, very far from other known populations.

IMHO, as I said before here, manzurii could be a end member of the schlimii species swarm of shapes and colors...

What a Q-T, whatever it may be!

x colombianum ?...Anyway for me it is the same species which has a large variability ...

 

[Seb63]

And we can have various form on the same plant like this one :






not very stable...and always a surprise ;-) (different dates, temperature ...)

Cutie!

 

[Phrag-Plus]

Wow!! That is very interesting! Thanks for sharing those very interesting photos incredible variations on the same plant..!

what a nice example! I've observed the same thing in some of my schlimii plants. Do you have a picture of the whole plant?
thanks a lot!

Interesting horns. I wonder if it will always bloom like that.

I think this part of Section micropetallum is rapidly evolving. Staminode shape, growth habit (ie - leaf width and length) and flower color are so variable that positive identification of species based on flower morphology appears to be almost impossible. What appears to be possible, is they're all varieties of "schlimii" in one form or another. Where is that point from which these swarms developed?

Tom, agree with you. Also a lot of work with DNA needs to be done in micropetallum section... but the main problem I can see is that it is VERY difficult to get the locations where the plants were collected...

Other interesting question is why are so rapidly evolving... The eastern Cordillera is being uplifted quite fast during the past few million years... but the central and western cordillera were much more "stable"... I wonder if this could be the reason why we found such variability in the Eastern Cordillera...

Eliseo,

It must be the reason why the species found in the Eastern Cordillera appear to be rapidly evolving! If I wasn't as old as I am, I'd love to try tracing the ancestral species to it's source using DNA analysis; what an adventure that would be!

Usually if you have a population swarm with lots of variability, it likely most recently emerged from a hybrid crossing and there are lots of different things being expressed as it back crosses continually. If the area where it's growing is geologically 'new' then places that previously could grow a plant no longer can, and vice-versa. The areas of North America that were recently covered by glaciers are now uncovered so species previously likely separated were able to join so invite the possibility of hybrid swarms with cyps and spiranthes
