Identification. P. esseriana or jaumavensis?

[jogaila]

Is it possible clearly identify - this is Pinguicula esseriana or Pinguicula jaumavensis? And to what details of the flower should I pay attention for the identification?

Thanks, Jeff

Here are the rest of photos picasaweb.google.com/musekautas.vabzdziaedis/PinguiculaSp?authuser=0&authkey=Gv1sRgCIPYrvW3xI6qhAE&feat=directlink

If I understood right: the thin darker stripes in the flower present - that's P. esseriana, absent - P. jaumavensis?

[jeff]

excuse me I have reverse the information to the picture ( it is right no)

esseriana have no stripe to the corolla throat , jaumavensis yes

for me with the others pictures it is a esseriana

For me, these two appear the same species, just from different locations... I'm not really understanding why these two are different... A couple of stripes on the flower vs. none is just a varietal difference.

And yes, I've grown both for a number of years.

Bonjour

I am OK with you DAVE but actually it is their name.

for me yes a variety or a form to P.esseriana .

why not an other name like P.esseriana var ( or f ) jaumavensis for me more adequat .

Thanks Jeff,

Do you know anymore about them, why the author thinks they are different?

Here is perhaps the best explanation (other than Debbert's original publication):

Bonjour

some others infos on esseriana , jaumavensis, debbertiana,ehlersiae

- Indeed, for ZAMUDIO esseriana var esseriana might be a hybrid.

what makes him say that's a test he did:
it has many colorful fresh pollen samples of3 types of flower, result a lot of pollen grains not absorb the color, they were empty, no cytoplasm or only a minimal amount same for normal pollen. For him, therefore, not grains explain the low viable seed production, so a low capacity for sexual reproduction.

- chromosome numbers (J.Casper,R.Stimper )

esseriana var esseriana 2n=32
esseriana var ehlersiae 2n=32
jaumavensis 2n=22
debbertiana 2n=22

may be a explanation why jaumavensis keep her name.

also my precedent message is not adequat.
