This is a rather pretty shrub, about four feet high, with pale woody branches, purplish twigs, and many, small, rich green leaves. The flowers have a glossy, bright green calyx and a yellow corolla, which is three-quarters of an inch long, streaked with dull-red outside and slightly hairy, the sterile stamen hairy and yellow.

Bushy Beard-tongue-P.antirrhinoides.
