Sanvitalia abertii

A low-growing DYC, found in the U.S. from southeastern California to western Texas, and common in much of New Mexico. The ray & disk achenes are morphologically distinct. S. abertii is distinguished from other Sanvitalia in part by having narrow phyllaries, these about the width of the ray achenes and not overlapping.
