Notes
S. squarrosus is often confused with Lipocarpha microcephala (R.BR.) KUNTH, which it deceivingly resembles in habit. The latter species is easily recognized by the narrow c. 1 mm long nut enveloped by 2 thinly membranous hypogynous scales, and by the widely patent or reflexed involucral bracts.
