Hi,

I just thought i could share these pictures with you. I have taken them about 2 weeks ago. Here they are :

HI Christian,

Just out of curiosity, do you know where your D.graminifolia is originally from? It'll probably be Caraça, Diamantina, Grao Mogol, or Itacambira.


Take Care,
Fernando Rivadavia
 
Hi Christian,

Serra do Cipo and Diamantina are different places in Minas Gerais state, SE Brazil, a few hundred km apart. While D.graminifolia is very common in the Diamantina area, it is not know from the Serra do Cipo. So I imagine your plants are probably from Diamantina, also known as the "spiralis" form due to the way the leaves uncurl (and because it was actually published by Saint Hilaire as D.spiralis, different from D.graminfolia).

Take Care,
Fernando Rivadavia
 
Hi Fernando,

Thanks for the Information! I have just looked it up. I received the plants with the location data i wrote above. I will aks the one, who gave me the plants soon if it was a mistake.

Nice looking plant Christian.

Looks a lot like mine. The leaves unfurl similar to the fiddleheads of a fern.
 
This is exactly the main difference between the type graminifolia (which due to pollution may be extinct in the wild by now, unfortunately...) and the northern forms. In the type plants, the leaves uncurl from a nice rounded bud, like the slice of a rolled up cake. In the northern forms, the whorls of the young leaves are usually not round, but oval and the internal whorls often stick outwards at different angles.

Hi,

as I am the one who gave Christian the plants let me say I have got the location data from the collector but I will ask him again next time I meet him for more details. Sorry for the problems I did not know that the places are so far apart. A foto of this location type in flower from February 2004:

Enjoy it!

Hi Fernando and all,

identifying that beautiful D. graminifolia would be great. In my eyes leave structure indicates the "spiralis" form but I didnot see a living specimen of the other type yet.
So here two pics of the above clone but of different plants:

and here two photos of another clone:

Hope that helps in identifying!

Collectors:

The first plant we now know should be from Diamantina was collected by Thomas Carow years ago and survived in the collection of Paul Debbert for years. In summer 2000 I started with Pauls last 2 plants and have brought it in vitro growing very good under sterile conditions.

The second one has the exact location data:

D. graminifolia northern giant, Itacambira FR2,

so Fernando guess who collected it years ago (around 1999) and was kind enough to send me some seed :-)). The plants flowered but so far I didnot get seed. Sometimes I have problems to get viable pollen from D. graminifolia and D. chrysolepis. As soon as I have seed they will go into tubes, too.
By the way most of the other plants from that time also do well. Only my beloved G. guyanensis seedlings didnot make it.

For those interested in Drosera graminifolia, note that this winter saw a specimen of this species frozen solid in its pot for a day or so. The plant is now returning to growth, much to my surprise. Evidently these plants have some resistance to brief freezes. The D. ascendens that was in the same pot is likewise returning to active growth, as is the Drosera regia which suffered the same fate.

The specimen that froze was received as seed from an Itallian grower who believed the seed was inviable, but sent it for my studies. It was labelled as Drosera graminifolia “Caracca” . I am wondering if this was collected by Fernando, or from another source? The seed germinated for me, although it was poorly stored since 1999. I am very happy the plant survived as it is a single specimen.
 
How do these beautiful plants deal with warm (70's) nights during the hot Georgia summer?
 
I get the impression from reading that they do alright with the heat but need a good overnight low dropoff.
 
JLAP.

I have two plants, one I keep inside under lights the other outside all summer.

They don't like it outside here in the summer :). It survived and grew, but looked rough. I moved it back inside now (just in time for it to get cool).

I can vouch for summer growing outside. Just brought in back inside and am not sure if the plant is even alive.
