Discussion
Plants with smooth, round seeds and larger, ovate to lanceolate (and not usually falcate) leaves have been segregated as E. ocellata subsp. arenicola. Leaf size and shape and seed surface sculpturing, however, vary considerably across the species range, and most individuals appear intermediate. Therefore a variable and more broadly defined subsp. ocellata is recognized here.
