How to Identify D.Intermedia vs. Anglica

[doug]

I am not sure how to separate Drosera Anglica from D.Intermedia.
Could someone explain it to me?

This webpage had a good description of the differences between them.

I happen to have a picture of the two, side by side, taken 2 years ago:

Thanks for the help.
On the following web pages it shows D. Anglica seed as being longer than D. Inermedia and D. Linearis. I would say the Anglica seed is more banana shaped.

I was at as site 2 days ago that was listed as having Anglica but when I looked at the seeds They are like the seeds of linearis. My question is this: If the seed doesn't look like the pictures in the links is it possible to be Anglica? Is seed shape definitive?

Seed shape is one of the best ways to ID certain things, f'rinstance the difference between D.peltata and (i sit now officially a ssp??) D.auriculata, conditions can change the habit of the plants but the seeds will not be altered too much.
BUT D.anglica grows in a LOT of places and there could be some forms with sorta atypical seeds...
Are you trying to ID plants that you've found?? I'm just curioous as to what you are trying to determine, and kinda why, maybe someone could be more clear if we knew exactly what you are getting at??

[doug]

I was at MacGregor Point provicial park and they list D. rotundifolia and D.anglica but not D. intermedia or D. linearis. When I looked at the seed of the plant they are calling D. Anglica It did not look like Anglica seed.

The plants look more like a small version of D. linearis.

Ooooh okay...
Quick answer- we went bogging a month or two ago and we visited that site, Purpman was determined to find D.anglica there as he had never had the luck before and is positive the species is present... we didn't get to stomp about too much in there, tried to stay on the edges (and didn't want to get in trouble, we were not there to ruin anything since we know what we are doing) but other than D.rotundifolia, what we saw was ALL D.linearis exclusively so maybe the seeds you are wondering about are in fact D.linearis

That is my two cents on that, maybe others could give better or different accountings tho
