Hi All.

I make a few shots of CPs in Imbituva, Paraná, Brasil ...
... a new location for D. viridis (?), but isn't a new location for
the other species, I posted a topic in this forum in 2008 (or 2009?)

U. praelonga


U. nervosa (seedpots)


U. gibba


U. nana


D. communis



D. viridis (?)


Regards.

Great field report. I especially like the U. nana.

[kisscool_38]

Great report Carlos  
A pleasure to see Drosera viridis, no so common in brazilian reports.

Hi Carlos ,

very nice pictures.
It really seems to be D. viridis you have found there.
Have all the plants been coloured greenish?
I´m asking because there are also existing reddish forms, for example the form from ´Parelheiros, SP´.

Thanks for sharing these pictures.

Best regards,

Dani

Nice plain whorl!

Hi All!

Jeff: I collect some spares of U. nana for try again this location, it's a difficult species, blooming is hardest.

Aymeric: I think that the people do not differentiate D. communis between D. viridis and then to photograph the D. viridis. I was to this place some times and in this only time I suspected that they were D. viridis.

Daniel: Reddish D. viridis? It's a new thing to me, I saw only green plants.
They would not be D. communis to me , but I'm not a taxonomist.

Adam, Jims and mr pc: Thanks.

Regards.

Hi Carlos ,

yes, reddish plants and i don´t think they might be D. communis.

My D. viridis ´Parelheiros, SP, Brazil´ are coloured deeply red (almost violett) in the center of the plant.



I´m also growing a form from ´Serra de Ponta Grossa, Campo Largo, Paraná State, Brazil´. These plants are under exactly the same growing conditions and the same lightning greenish like the plants you have shown here.

Best regards,

Dani

Very red, I loved ...   ... I saw only green plants, look like a mutant D. viridis or a hairless D. communis.

" ... It is distinguished from D. communis by its overall larger size; leaves always green, never turning red even when exposed to direct sunlight ..." (Rivadavia, 2003)

Hi Carlos,

yes, i know Fernando´s species description.

Here is a link about Matthias plants from the same location:
http://www.cpukforum...s...&hl=viridis

So it seems so as if there is also existing a reddish form.

Best regards,

Dani

[Carlos Rohrbacher]

I liked, iIt's a beauty and unusual 'viridis' (viridis = green)  

Do you have flower pictures?

[Daniel O.]

Hi Carlos,

for my sadness my plants have not flowered till now, i really don´t know why.
But for sure the plant is mature.

In the link i´ve posted Matthias is saying that his plants are in flower nearly all the time, really strange.

Best regards,

Dani

[kisscool_38]

Unless it is red, stipules and petioles are consistant with Drosera viridis from Fernando description.
By the way, I didn't know there was a "red form" of Drosera viridis. It is a very beautiful plant, I love the contrast between the red petiole and the green lamina.

Regards

Aymeric

[Fernando Rivadavia]

Hi guys,

Not sure we can start calling it a "red form" of viridis yet, hehehe! I have seen in the wild plants that have reddish petioles (but not lamina) similar to the ones grown by Matthias, although only in very rare exposed & sunny conditions. But I have never seen plants as res as yours Dani, and I can only imagine that this is due to your artificial lighting (different wavelengths? very intense?). Very beautiful, but in nature they do not look like that.

Either way, there are other morphological characters to distinguish viridis from communis. The most guaranteed way I have to convince the unbelievers is to visit a natural location where both species grow together, to show them how different they are side-by-side. :)


Best wishes,
Fernando

Hi Fernando,

you are right, i should not call it a "red form", i only wanted to say that it´s very reddish in comparison to plants from other locations.

Yes, you are right, i´m growing them under artificial light (2 bulbs, T8 36Watt/840 and T8 36Watt/865). The distance to the plants is about 13 cm. I´ve not exchanged the bulbs since about 9 months, so the light should be not so good as at the beginning when i´ve exchanged them.
BTW, it´s one of Matthias plants, and i don´t think my lightening is more intensive than his lightening.
Perhaps the colouration has also something to do with the colder night temperatures the last few months, i really don´t know.

I´m also growing D. viridis ´Serra de Ponta Grossa, Campo Largo, Paraná State, Brazil´ and they are growing exactly next to each other but the plants are greenish, even the petioles are not reddish (sorry for the bad picture quality).


In my opinion there is a big difference in the colouration nethertheless they are growing next to each other.

Best regards,

Dani

[Fernando Rivadavia]

Hello Dani,

I don't doubt that there could be variations within D.viridis, but not sure this is what you're seeing.

Or both! :)

This plant does not seems as big & healthy as your red ones. Could it just be an age difference?

All the best,
Fernando

[Daniel O.]

Hi Fernando,

both plants are nearly identical in diameter, about 2 cm.

You are right, the green plant doesn´t look very healthy in the moment (i´ve even lost a few of them); that was also the reason why i did not show it at the beginning.
Since a few weeks it´s growing better (first leaf with dew); i received the seed about 18 months ago, but from the beginning they have been greenish.

The red plants are about 3,5 years old and they are forming "stems", so perhaps really the age is responsible for the different colour.
They have not always been so deeply coloured but they have always been reddish.

Best regards,

Dani

[Carlos Rohrbacher]

Which the conclusion? In my last picture is a D. viridis?  
This red plant is a D. viridis 'cultivar'?

[Fernando Rivadavia]

The conclusions are:

1.) Carlos, we can not ID your plants 100%, we would need more & better photos.
2.) In exceptional conditions (very bright and/or cold nights) , it seems that D.viridis CAN get reddish.
3.) Dani may have detected a slight genetic variation between D.viridis from 2 locations, which after more investigation he can decide whether to publixh as a cultivar. But for now it is still simply D.viridis without any other names attached.

Best wishes,
Fernando
