Members of the genus Geranium are commonly encountered; they can easily be distinguished by their dissected palmate leaves and weirdly elongated seed-pods, which due to a fancied resemblance causes several species to be known as cranesbills. I have long been familiar with Midwest woodland species of Geranium, such as the common Wood Geranium or Alum Root, which some refer to as the Old Maid’s Nightcap: Geranium maculatum.
Here in central New Mexico I’ve been seeing profuse growths of another species, one with a very spiny and elongated seed-pod. You might say that the pod is a caricature of the actual bill of a crane. I’m not sure of the species, but suspect that it’s a native of Europe that has found a new home in the US, as have so many other Europeans.
