A weed? A D. rotundifolia?

A weed or rotundifolia?

Yes.

Seriously though, it's certainly not a weedy drosera like capensis or binata. Could be rotundifolia - has the look of one about it.
 
The more I view this the more it looks like Drosera capillaris to me. The first two photos aren't showing up.
 
I agree with NaN on D. capillaris. IMO, it also looks like it might be D. intermedia.
 
Links were removed but here's the weed with D. manni:

I think so too. It looks like the extremely pale capillaris I got growing under florescents...

Nice plant, though.
 
Hmmmmm, not D. rotundifolia or D. intermedia. Might be D. capillaris - are there any hairs on the underside of the leaf?

Doesn't appear to have hairs. I had to lift up a leaf. They are all decumbent. I ruled out capillaris, spatulata, and intermedia because spatulata has a wider leaf that blends in at the trap, forminging the spoon shape. D. capillaris have a more elonganted trap that this one has. This is a circle.

Here's what I mean:

Here's the plant in question:

This is D. capillaris:

This is D. spatulata:

And this is an old picture of now out of the collection D. intermedia and D. anglica:

I am far from being a reliable source of ID but these leaves and traps just don't look like capillaris, spatulata, or intermedia.

Here are D. rotundifolia seedlings that came and went a couple years ago:

Idk, Jim. My tiny D. rotundifolia have leaves that are quite wider than your sundew in question. I would have to lean towards D. spatulata on this one.

...Maybe it's a hybrid of another form of capillaris? Now that I think about it, it looks more like capillaris.

Edit: You can see here D. capillaris as various forms. It kind of looks like the last one.

Jim i believe the spatulata you have is the frasier island form, much different than the regular form. could also be Tokaiensis, here is a pic of a pot of spatulata and tokaiensis (Old photo)

D. capillaris comes in many forms. The clump I send you is "long arm"/"long leaved".

Here are some other forms:

Drosera capillaris

Although it is difficult to make out from your picture it appears that the immature leaves do not have the glandular hairs so characteristic of Drosera spatulata. Thus Tamlin's question if there are hairs on the underside.

Here's some crappy snaps of a sole survivor of the clump D. capillaris you sent me two summers ago. Perhaps what you have there are from seeds of siblings. There were flower scapes on a few plants in the clump when I received it.:

BTW: I have seed from the Drosera intermedia that you sent me, and I think some of NJ Pine Barrens D. intermedia. I'll have to check my seed bank. I also have limited amounts of D. anglica seed, some generic non-location, Hawaiian from two locations and some CA x HI. The HI and CA x HI are a snap to grow with no dormancy requirement. If I had read your caption earlier I would have sent some out with the D. ordensis anthers. Next time.

Thanks, Warren! I guess I'll have to wait for this plant to flower. Hopefully, it will. Looking at the pictures it seems that it might be the non-long arm form. Darn!

Your "D. capillaris" is a Pinguicula. Your mystery sundew looks like a pygmy sundew. See the little hairs in the center?
 
  • #15
Okay.. who put a butterwort in there! LOL! Which pygmy sundew, though?
 
  • #16
Who knows? A flower would help in that category. I can't tell without a flower.

BTW, white looks good on Pinguicula. :D

EDIT: Just read a few posts ago. Too bad it hasn't flowered yet. Keep us posted, though.
