G. filiformis - correct ID?

Recommended Posts

Hello,

i have a few plants of genlisea, which i grew from seeds about two years ago. They are now adult and in flower. I got the seeds as G. filiformis and i think it looks like filiformis on CPPF (i checked especially the photos which Fernando marked as true G. filiformis), but your opinions would be welcome to make sure that my feelings are correct.

Thanks in advance

Hi Adam,

Actually that's G. pygmaea!

I can tell you by the very dense eglandular hairs on the sepals (in G. filiformis the sepals are almost glabrous), and the acute apex of the spur (vs. rounded or truncate in filiformis).

Interestingly the flower looks too pale, but that can be environmental.

Best Regards,

Paulo

Hi Paulo,

thank you for ID, but i am quite confused now. I am finishing a research on Lentibulariaceae genome size and this plant has more than twice larger genome then typical G. pygmaea. Can G. pygmaea have 10 - 15 cm long flower stalks? Or it might be a hybrid of something??? Or could it be, that G. pygmaea (or Genlisea at all) can occur in several ploidy levels? I can try to make some more pictures if you want to see something more.

Thank you

Adam

Hi Adam,

Do you have any picture of what you call 'typical G. pygmaea'?

I ask because there's a lot of confusion regarding the ID of G. pygmaea and closely related taxa - mostly new species that were misidentified as G. pygmaea in the past. It is possible that your plant is a closely related species from Brazil (not yet described) that shares several morphological characteristics with G. pygmaea, but is much more robust (that could explain the different genome sizes). What's the size of the flower?

Best Regards,

Paulo

Hi Paulo,

this is what i know as "typical" G. pygmaea, at least among growers here in czech:

The flower was 7 mm long and 5 mm wide from tip to tip.

How many undescribed species do you think will be described in the future? I am just curious...

Best regards

Adam
