Pecos River Skeletonplant

Lygodesmia ramosissima Greene

Comments

provided by eFloras
Lygodesmia ramosissima is often confused with the more widespread L. texana; it can be distinguished by its thinner, more intricately branched stems, 5–7 florets per head, sulcate cypselae, and later daily flowering time (A. S. Tomb 1980).
