A thought: This summer, I gave myself the goal of photographing every kind of wildflower in my area. It turned out to be quite a large project; I ended up with about 6000 images of perhaps 130 species. When I started, I figured the big question I would be answering would be this: - Here is a plant; what species is it? But as I progressed, I found myself confronted with the surprising difficulty of answering a somewhat different question: - Here are two plants; are they the same species? This article suggests yet a third question: - Here is a plant; is it a known species? It is interesting to think that, for some of my 6000 images, the answer may just be "no".
