I agree with venusta, my plants are also hairy.

This is closed to what I received and I'm currently growing under the name Drosera esterhuyseniae.

[Daniel O.]

I´m wondering a little bit about the very strong hairyness of the leafes, but in my opinion it´s not D. esterhuyseniae.

My D. esterhuyseniae are looking this way, in my eyes very different in comparison to the pictures above (especially the leaf shape).

D. esterhuyseniae (sorry, an older picture but in the moment i´m not in Germany to take new pictures)

Best regards,

Dani

I'm not clear about some South African species, but all the examples of Drosera I've seen labeled as "venusta" match the photos. I have no idea what D. esterhuyseniae looks like...

[Zlatokrt]

I know D. esterhuyseniae to look like the plant on Dani`s picture (or like on this picture http://www.darwiniana.cz/vamr/?page=obrazek&id=3581 - this is from the greenhouse of Christian Dietz). The hairiness on D. venusta is not usually so strong and visible, but is still present, at least i remember to see some hairs on my plants.

the picture of the flower does not help ?

I agree with you Daniel that his plants and mine are more probably an hybrid involving D. esterhuyseniae (the one you showed) and D. venusta.

However, Christian's and your plants are in my opinion far from the pictures Christian has taken during his trip to South Africa:

But I have to admit I have no idea of what it could be.

Set name on a plant is allways dangerous,the are so many plants that looks allmost tesame on a pic,you are never sure.A plant can looks very difference in someone others cultivation place,or in the wild! Or am i wrong?

Crossings and mislabbeled plants came in roulation on this way.If you will set venusta on this ,you must mark whit ? Whitout any sources you are never sure ,or am i wrong again with this?

Keep in mind:This is only my opinion,what someone els think or do whit this is his matter,i know this is a very tricky item and some people have a totaly other thinking on this.

I personaly set never names by unnamed plants or i must be 100% sure and even then i mark whit a ? on the etiket,except for plants like cephalotus and darlingtonia!

Sorry for my bad Englisch ,i hope you not misunderstand anything,i do the best i can!

Cheers Willy,

Well, i have just checked D. venusta isotype on D. venusta isotype (it works on our university PCs, i hope someone can see it too) and i see some nice hairs on both sides of the petiole.

I also checked the holotype of D. esterhuyseniae (or D. curviscapa var. esterhuyseniae as they have written there) and it is not so much different from the plants which Daniel and Christian grows. It also does not look to me that the pics from nature are so different from the plants from culture - at least i think, that Christian would doubt his plant, if it looked too differently from the plant in his greenhouse. The blades of plants in nature look a little wider, but only on the close-up, on the photo of group of plants from above it is not so obvious. Hard to say...

My D. esterhuyseniae have not flowered till now so i´m not able to compare the flowers, but i´ve the confirmation from Andreas Fleischmann in the german forum that the plants i´m growing under this name are real D. esterhuyseniae.

But for sure it´s also possible that different growing condition can make the same species looking slightely different, a very good example for this is D. sessilifolia.

Best regards,

Dani

Hi,Paulo!

The plant you showed picture of in the first post of this topic is NOT d. esterhuyseniae, according to my opinion. It is drosera venusta.

The hairs is not a distinguishing feature here. I am growing d. venusta with very little (almost none) hair and also other whitch is quite hairy, especially on the petioles.

Aside from flower, it is the leaf shape that is (according to me) quite different fro d. venusta and d.esterhuyseniae. The latter one has wedge-shaped leaves, it gradually widens, with no distinct convexity, resp. curvature, whereas for d.venusta, you can easily see the curvature at about 1/3rd of a distance from the end of petiole.

Of course, the deciding feature is flower and seed size/shape. I say it is d. venusta, not d. esterhuyseniae. Would not be very happy to see more mislabelled plants in ciculation.

Thay are beautiful nevertheless! Best regards,:-)

I agree with you, that's why I have many plants of this unidentified specie because I don't want to sell or trade.

This plant was bought many years ago in a online carnivorous plants shop as D. aliciae, it was small, but when it became bigger it was obvious that that identification was wrong.

By now I always cut the flower stalk, but I left one so I can take the foto, I hoped that the flower piture would help.

I post here this question to see if anyone could give have a correct identification, but with this kind of doubt I think I have a nice plant but it will stay without a label...

[dudo klasovity]

may I ask how long was the flower stalk?

My d. venusta/coccicaulis is flowering now and has extremely tall fs. Up to 65cm. Here are some pics:

Dear Willy,

Yes, I think you're wrong. Most species have rather distinct shapes to the leaves and many other features like the seeds. Even hybrids are different enough to often mistaken for new species before the ecology is sorted out.

cp_produtos' plants and everyone else's D. venusta are a solid match.

Dani's plant is clearly another species.

OK then i am wrong,but i never say it s not venusta,probably its venusta,but only iff this is sure for 100% .

This is why i say its not easy item,everyone have other thaugths off these ,some people love it to set names on unnamed plants ,others not like it ,everyone must do what he most like,so no problem att all.

The problems came only when you see after a long time that you have a mislabeled plant,

Cheers Willy
