Mabrya acerifolia

Mabrya acerifolia, or brittlestem, is a mat-forming herbaceous perennial native to south-central Arizona. It has pale yellow tubular flowers. It was first described by Francis W. Pennell in 1924 in the genus "Maurandya" and transferred to "Mabrya" by Wayne J. Elisens in 1985. The epithet "acerifolia" refers to the somewhat maple-like shape of its leaves.
