The word "Rhamnus purshianus" has its etymology rooted in both Greek and Latin.
The genus name "Rhamnus" is derived from the Greek word "rhamnos", which means "buckthorn". This is in reference to the plant's classification in the buckthorn family (Rhamnaceae) and its characteristic appearance, with spiny branches and often small, greenish-yellow flowers.
The specific epithet "purshianus" pays homage to the American botanist Frederick Traugott Pursh (1774-1820). Pursh was a German-born naturalist who extensively studied and described North American flora, including the buckthorn species now known as Rhamnus purshianus.
