It's hard to follow the plant profiles. Even when it's not a great profile, I've put enough effort into it that I usually don't have time to come up with something else. So: transmitted light photos.
(The previous transmitted light posts can be found here.)
Taraxacum officinale. This one, on the other hand, is unpleasant because it was taken at the end of fall and the leaf in question was old. There may have been mildew on it too.
Fragaria x 'Fort Laramie,' autumn. I was reminded last fall how brilliant the colors can be on strawberry plants. One of those things I knew at one time but forgot about.
Colocasia esculenta. If you only concentrate on the darker areas around the main veins, this sort of looks like a few very carefully-arranged green feathers.
Weigela florida 'Alexandra.' If I'm reading correctly, the on-line consensus is that this is the same as 'Wine and Roses.' Looks pretty, whatever you call it. A little dark for the yard, maybe.
Stromanthe sanguinea 'Triostar.' These often turn out nicely, but I rarely think that the photo came out looking like the leaf actually looked in person. This one isn't quite right either (though it's still a nice picture).
Quercus sp., autumn. I have a lot of autumn Quercus photos stockpiled; this isn't the best one by a long shot, but it's still my favorite from this set.
