Peraphyllum ramosissimum is a handsome shrub growing to five feet tall and wide, and although it is not as common as its two ubiquitous companions Purshia stansburiana and Fendlera rupicola, it is common enough to be fairly easy to find in the low mesas and foothills. And once you have found one Peraphyllum ramosissimum, you will probably find many more nearby. 

Peraphyllum ramosissimum has been in our area for perhaps 50 million years as evidenced in fossils.

Thomas Nuttall named this genus and species in 1840 from specimens he collected on "dry hill-sides near the Blue Mountains of the Oregon" on his trip West with the Wyeth Expedition of 1834-1837.  (Nuttall's words as quoted in Intermountain Flora.)

"Peraphyllum" is Greek for "very leafy" and refers to the crowded clusters of leaves.  "Ramosissimum" is Greek for "many branches".

For many decades this plant was known by the common name of "Squaw Apple". I have not been able to determine the origin of that name, but since the word "squaw" is commonly thought to be a pejorative, I changed the name on this website to "Wild Crab Apple". Click to read a more complex understanding of the word "Squaw". Click again for another well-informed understanding of the word. Both of these articles indicate that the original meaning of the word "squaw" is "woman" or "young girl" from the Massachusett Algonquin language (present day Boston area). Also see Wikipedia and do a search for "squaw" on that Wiki page. Also read this well-reasoned discussion about changing the name of many California "Squaw" names.

As occurs with many words, in many parts of the world, in many languages, among many paranoid, mean-spirited people, the word "squaw" has been corrupted. To mock, slander, and defame, seem to be the pleasure of all too many people. We should not allow them to corrupt us and our language. Unfortunately the word "squaw" has been so widely debased that I dropped it.
