I have taken pictures of more that 400 flowering plants already, although many of them are still on my unidentified list. Sometimes I find a plant with its seeds and have to wait 2-3 seasons (or never!!) before I find it in flower. I have walked many many kilometres in search of new plants. Some have been found only once and never again.
I have also learnt that when I find a new plant, I have to take as many pictures as possible – immediately. Because tomorrow it might not be there anymore – withered or inside the stomach of another organism.
