Cactus and Clouds – Curves

Clouds are not as common in Arizona as they are in Alberta. One day, however I saw these ‘comma’ clouds, with a trio of Saguaro cactus stretching up as if to catch the wisps!

These clouds reminded me of punctuation. Don’t they look like big apostrophes or commas except they curve the wrong way?  I think they are Cirrus uncinus clouds, but I’m not sure.

The cactus with the curved arms are Saguaro cacti.
