At the end of last summer I noticed a Siberian peashrub (Caragana arborescens) growing on the south end of BYU campus. It was near the stairs that lead up from the botany pond [1] to the Benson Building (chemistry building). Since legumes have become a recent fascination of mine [2], I decided to photograph the plant and upload the pictures to Wikimedia Commons (the media repository for Wikipedia). It was at this point that I discovered something unique about the seed pods. Every time I tried to pick one of the seed pods, it would explode in my hand, scattering its seeds everywhere. Then I noticed that some of the seed pods burst open while still on the tree.[3] Only by being very careful was I able to collect some for the photographs. The photos then took up residence on the desktop of my lab computer until last week.
The reason I waited to upload them to Wikimedia Commons is that I wanted to scrub the backgrounds and replace them with a solid color. It isn't that hard to do, I just put off doing it. The photographs I took were off the leaves, the seed pods, and the seeds. I went ahead and uploaded them as-is.[4]

As you can see, the black felt reflected a lot of light and I didn't really like all that texture visible back there. So I used the GIMP [4] to change the backgrounds to a solid color. Here are the final results:
I think they look a little better now. Along with uploading the retouched photographs to Wikimedia Commons, I also included the photo of the seeds on the "Measured seeds" media page (here) and all three on the "Caragana arborescens" media page (here).
