Cleomella palmeriana Semi-desert. Sand and clay openings. Spring. It is easy to pass this plant by as a Cleome lutea but Cleomella palmeriana is only about one tenth the size of Cleome lutea and when the two plants are in fruit another distinguishing characteristic becomes apparent: Cleome'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 of his in Utah in 1890. The word "Cleome" is of uncertain origin and "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).
