Notes
S. pumila is a polymorphic weed segregating into regional populations. These overlap to such an extent that the recognition of more than one species cannot be upheld, though there may be a case for distinguishing between tropical and Mediterranean populations at infraspecific level (Clayton in K.B. 33: 501–503 (1979)). Much argument has been devoted to the nomenclature of this species (summarized by Terrell in Taxon 25: 297–304 (1976)), but it now seems that the commonly used names S. glauca and S. lutescens should be referred to Pennisetum. S. pumila is closely related to the caespitose perennial S. sphacelata, and specimens lacking their basal parts are often indistinguishable. It is even more difficult to separate from S. gracilis Kunth (= S. geniculata auct., non (Willd.) P. Beauv.), the common American species which also occurs in Tropical Asia; this is a short-lived perennial, commonly with short knotty rhizomes bearing dormant buds, though the perennial habit is not usually very obvious.
