Cleomella palmeriana

Cleomella palmeriana (Palmer's Bee Plant)
Cleomaceae (Cleome Family)
formerly Capparaceae (Caper Family)

Semi-desert. Sand and clay openings. Spring.
Southeast Corner of Utah, April 17, 2010.

It is easy to pass this plant by as a Peritoma lutea but Cleomella palmeriana is only about one tenth the size of Peritoma lutea and when the two plants are in fruit another distinguishing characteristic becomes apparent: Peritome's fruits are much longer than broad with numerous seeds; Cleomella's fruits are about as long as broad and have two to twelve seeds.

Cleomella palmeriana was named by Marcus Jones in 1891 from a collection he made in Utah in 1890.  The word "Cleome" is of uncertain origin; "Cleomella" means "tiny Cleome".  Edward Palmer (1829-1911) was a highly respected botanist in the American Southwest and in Mexico.  (Click for more biographical information about Palmer).
