Discussion
Variety salsola refers to plants bearing burs with 6–14 wings in 2–3+ cycles, their tips ± spreading to patent; var. pentalepis (Rydberg) Strother & B. G. Baldwin refers to plants bearing burs with 5–9(–13) wings in 1(–2) cycles, their tips ± spreading to patent; var. fasciculata (A. Nelson) Strother & B. G. Baldwin [= Hymenoclea salsola var. patula (A. Nelson) K. M. Peterson & W. W. Payne, an illegitimate name] refers to plants bearing burs with 10–18 wings in 2–3+ cycles, their tips antrorsely ± appressed (see K. M. Peterson and W. W. Payne 1973).
Hybrids between Ambrosia salsola and A. dumosa have been called A. ×platyspina (Seaman) Strother & B. G. Baldwin.
