As I said before trying to identify species through photographs with obovate, spatulate, oblanceolate, or oblong leaves is difficult. How the leaves appear in a two dimensional photograph depends a lot on the perspective, angle and lighting. These can be affected by focal length and position of the lens (distance and angle).
If you look at Harry A. Gleason's key to American Drosea leaf shape doesn't play a role in distinguishing between Drosera capillaris and D. intermedia. Rather the key depends on flower color (pink for D. capillaris and white for D. intermedia) and the appearance of the seeds. I've stressed this many times before - flowers and seed will give you the best keys to identify between theses species.
(after eliminating D. filiformis, D. rotundifolia, D. linearis and D. anglica we are left with the following:
Here is an example of how the angle at which a photograph taken can affect the perceived leaf shape (two dimensional image)Stipules free or lacking.
Scape glabrous; stipules conspicuous, free
Flowers white, 7-8 mm. wide; seeds irregularly and densely covered with
long papillae, 0.7-1 mm. long. -> 5. D. intermedia
Flowers pink, 10 mm. wide; seeds papillose-corrugated with 14-16 ridges,
0.4-0.5 mm. long. -------------> 6. D. capillaris
Scape glandular-pubescent; stipules absent; seeds crateriform, 0.3-0.4 mm.
long. ---------------------------> 7. D. brevifolia
Same leaf, same plant different angle. I'll leave it to you guys to debate the species. It is a species and quite mature - there are 4 or 5 old flower stalks and a new one on the way.
