Banfora zone in Burkina Faso, sept. 2005

Recommended Posts

Hello all,

I had the opportunity to visit the nice zone around Banfora in southern Burkina Faso. I found CP in two places I visited in last september :

-Fabédougou domes and the zones between the domes and Karfiguela waterfall. At this site I found a Drosera species (I guess D. indica, ???), and one or two Utricularia species.

Plants can be found both at bottom of cliff and on the plate.

-Sindou about 50 Km from Banfora, similar habitat, I found Drosera on a thin layer of sand over the rock, this place is drier than Fabédougou.

There were also some Genlisea a few meters before, on a more humid substrate, I think it could be G. stapfii (known from Ivory Coast), but I'm not a specialist. If some have other guesses about Drosera and Genlisea identifications, please let me know ;-)

If some of you know who I can contact for an advice or where and how to send specimens for identification it would be great. :?

Great pics from a not very often visited region of the world Michael, thanks for sharing it!

In my opinion the Drosera is indeed D. indica as it is known at the moment, but looks like the complex needs to be divided up in future.

Kindest regards

Stefan

Hello Michael!

Stefan immediately told me to answer to this topic! ;-)

Very nice photographs of habitat and plants!

Yes, the Drosera you found growing there indeed is D.indica, the "common" (i.e. "out-of-Australia") type (which most closely hits D. indica s. str., therefore this plant will even be D. indica when the complex got split up [hopefully on subspecific level only!]).

Considering the beautiful Genlisea, I would rather think it is G. barthlottii than G. stapfii. First, the flowers seem to be a little bit to large to be of G. stapfii (and the spur of the flower of your plant is much longer than its lower lip!). Moreover, the seed capsule seems to be covered with short glandular hairs as well as with longer stalked ones, a good character to distinguish G. barthlottii from its close relative G. stapfii.

The only problem: G. barthlottii is so far only reported from Guinean inselbergs, as far as I remember correctly. (I will check my notes as soon as I'm home from university this evening!)

I do not have any access to my Utric literature here, too, but my tip for the tiny lilac Utricularia which hides on your 2nd photograph: U. arenaria.

I promise to check this as soon as I'm home again, too! ;-)

If you whish me to properly identify your plants, you can send me some specimens, of corse! You can e-mail me privately: [email protected]

All the best,

Andreas

Andreas, thanks a lot for your help I will send you an email soon. Maybe I could have fresh specimens as my friend and guide is coming to france soon. If so I will send them to you. I have some good contacts in the area so I think I can obtain more informations and plants (live ? preserved ? if so, how ?).

Best regards, Michael Negrini
