A Few Drosera

[STpaMan]

I bought a small collection of plants last year. It wasn't labeled very well. I could use some help with Id's, any help would be appreciated. All of these plants are growing in the same tray outside in full sun.

Plant #2 it's in a 2 inch pot, very small plants.

Plants #6 I know the plant in the upper left is some kind of pygmy

Plant 4 is D. capensis, probably 'narrow'. I have some thoughts about a few of the others, but I would rather someone else with more experience take a guess.

Looks like you bought a boat load of D. rotundastickya and D. spatuhaha.

#1 D. spatulata or some such. Looks like what I have growing as ssp. lovellae

#3... D. capillaris, perhaps? Reminds me a lot of the plants I'm growing (Polk Co., FL locale).

#4 looks more like D. anglica to me than D. capensis.

#4 looks more like D. anglica to me than D. capensis.

Now that you mention it, it does look more like anglica.

 

[Not a Number]

D. anglica doesn't form a stem. It doesn't appear to have the big papery stipules of D. camporupestris. And D. camporupestris typcially does not bend near the petiole. My verdict is D. capensis.

#2 I would suspect D. brevifolia.

Pictures of flowers would definitely help.

 

[Bio]

That stem was bothering me, and I think the leaves just look like anglica due to the odd angles they are at in the picture. It's D. capensis.

As for the others, I have no idea. They all look pretty much the same to me.

The traps are pretty short for capensis, though, in my opinion. And they seem to be wider near the center than either end. Interesting plant either way.

Plants 1 and 2 are likely different forms of spatulata, the latter looking a lot like the "Kanto" form
Plant 3 is capillaris, probably a long arm form.
Plant 4 is D. affinis, not capensis or anglica
Plant 5 is probably that squat spatulata form again
Plants 6 are a bit young to determine right now, could be capillaris or intermedia.
I can rule out brevifolia for the squat plants, I grow that species, doesn't look at all like them.

D. brevifolia Hampstead, NC comparison. Flower photo courtesy Ivan Snyder. Under my lights in tropical tank these plants don't color up, but they grow for years instead of dying after winter outdoors. Boxes indicate plants in cropped comparison (most similar perspective). Both mine and Snyder's plants are in 2.5 inch pots.

Here is D. kaieteurensis, which some people find nearly identical to D. brevifolia, however the flower stalks are different

Flowers and seeds will tell the tale:

Drosera brevifolia Pursh. Petioles 5-10 mm. long, dilated, glabrous. Leaf-blades cuneate, 4-10 mm. long, usually longer than the petioles. Stipules absent or reduced to one or two minute setaceous segments. Scape 4-9 cm. long, bearing 1-8 flowers about 15 mm. in diameter. Sepals glandular- pubescent, oblong-ovate, 2.5-3.5 mm. long. Petals rose to white, obovate, 4-5 mm. long. Seeds black 0.3-0.4 mm. long obovate, oblong, caudate at base, crateriform, the pits in 10-12 rows.

Thanks everyone for your help. I was thinking plant #1 is some form of spatulata, it keeps getting bigger every time I look at it. I is kinda of ironic if #3 is capillaris (Polk Co. form) since I live 10 mins. from Polk Co. Plant #2, now that I think about it, nearly all the plants disappeared during winter. While plant #4 did not go dormant during winter. I know it isn't a capensis, all the capensis I own are huge and won't stop flowering. Plant #5 I thought was a spatulata until it bloomed the flower was small white (pygmy like) and the flower stalk only grew to about three inches tall. Plant #6 could be intermedia, though all the intermedia I have grow so fast and these seem to be happy staying small. I found some more pictures maybe they can help.

This is what all my D. capensis look like. (We get daily thunderstorms that have been beating them up)

This is intermedia right (I know eyes to big for it's mouth)

Okay, so it looks like plant 2 could be a different form of brevifolia, though that flower stalk in the first pic is a lot thicker than any of mine ever are, and not as glandular. The second pic looks a lot closer to mine. And again I say with 99% confidence, plant 4 is D. affinis, a tropical, stem-forming plant with long petioles and marginally elongate lamina.

 

[STpaMan]

Thanks hcarlton for your help. I agree plant #4 must be D. affinis. I'm not sure but I think if it were D. anglica the Florida heat and humidity would have 'numbered it's days' last summer. Plant #6 looks like their gonna be D. intermedia, they coming up all over the place. I got most of all three trays of Dews including a great D. spiralis and a monster D. regia from the one purchase.

This is what it looked like in the spring about 4 months ago.
