^bSame references indicate different study areas or community types; transect data used only in cases where single vegetative zones were sampled and when no obvious elevational gradients were present; lists taken from some community types are from sample plots where S. robustus had highest frequency or cover values. Except for a few common species, e.g. Phragmites australis (synonym= P. communis), no attempt has been made to eliminate synonyms.
