It is distinguished fromS. lautuss.s. by its taller sparingly branched, strictly erect annual growth habit, succulent stems and foliage, and oblong-spathulate, irregularly serrate or lobulate, deeply toothed leaves. It has fewer involucral bracts, disc and ray-florets, shorter often twisted ray-florets, and smaller, sparingly hairy cypsela. [ABSTRACT FROM AUTHOR] |
