Title: Clematis hirsutissima ? with pictures of leaves
Post by: PaulM on July 21, 2011, 01:02:58 PM
I collected this Clematis species in Colorado ( Florissant Fossil Beds National Monument ) in 1999, and I wonder if anyone can help me with its identification. The leaves are whole. I wonder if it can be a variety of C. fremontii ?

It looks like Clematis fremontii but I'm not a clematis expert.  Attaching a picture of C. fremontii in my garden.

Can't put a name to this Paul but C.fremontii's range does not go as far west as Colorado to my knowledge. It is mostly restricted to Kansas and Nebraska with a single location in Missouri.
Panayoti should be able to ID this.

It should be hirsutissima if its from Colorado. Are all the leaves entire? Is it an herbaceous perennial or a scandent vine? It could be dictyota (pitcherii variety dictyota) which would be superb to have for molecular work currently underway!

 Fremontii is known from 1 site in Tennessee, 2 in Georgia, a couple dozen in Missouri, and in Nebraska and Kansas it is very abundant in the right geological formation. The Missouri plants are somewhat scrambling and more slender than the others. The Tennessee material is very hard to separate from the Kansas/Nebraska stuff.

I posted some pictures of this Clematis which I collected in Colorado in 1999 about a month ago, and Aaron Flodén gave me the folllowing reply:

I have taken some pictures of its leaves now, and they are not all entire.

It dies down to the ground in the winter, and produces several procumbent ( up to 50cm long ) stems in the summer.

Here are the pictures:

Paul, I felt it would be useful to combine the two threads about your Clematis from Colorado. :)

Thank you Maggie ! That's something you can only do as a moderator, right ?

That's right, Paul..... I can't do anything really useful, like whipping the tablecloth from under the dishes  ;D

Maggi,

How exactly WOULD that be useful?

Lovely Clematis, particularly that full shot of fremontii.  One to try to find if possible, as that looks stunning.  :o

How was Paul able to post pictures when the facility is down? ???

Lesley,

I'm guessing that the facility is back up.  I saw pics posted elsewhere and wondered the same thing.  I haven't tried actually posting a pic, but the option is there and I can bring up the available list for uploading a pic, so I guess it is working again?

Yes Folks, Fast Fred has things back to normal.... or as "normal" as anything ever is around here!! ;D



Paul:  I could astonish guests at dinner..... isn't that useful ?

Um..... I'm not entirely sure.  Also, I'm thinking that "astonish" might perhaps be a slightly strong word for it? :-\

Oh wait, you were meaning that you would actually leave the plates etc still sitting on the table in perfect condition? :P

Yes! Whip the table cloth off and leave all the plates and glasses standing perfectly on the table.... ;D ;D
astonishing!

See I could astonish them too, Maggi.  I could whip the tablecloth off the table and scatter all the plates etc to the four winds..... I think that would astonish my guests as well.  ;)

Nah, Paul.... that would HORRIFY your guests....... my way is much better!

 (Or would be, if I could do it. Can't understand why Fred hasn't arranged it as a Moderator's tool for me.... and he still hasn't got us a working scent button for the Forum  :'(   )

Definitely C. hirsutissima. It can vary in the leaf lobe character. Some are very fine and hairy while others approach the entire-leaved eastern North American spp or that one outlier in eastern Europe.
