Pencilled cranesbill - Geranium versicolor

Oh man, the picture isn't really in focus. Nevermind, you can get the picture. This species is a garden escape, and introduced species. Its veins are deep purple making it look as if it has been drawn on in pencil and the petals are notched at the end. The flower can be white to pink. I found it in growing in a scrubby wasteland area at the back of some gardens.
