There is such confusion involved in the name of S. confervoides for this species 
that it is better avoj It was originally described by Poiret from Madagascar ; 
he aang the two long barren glumes enclosing the spikelet (which will not at 
ull do for §. tonuissimus) Kanthe following, describes the spikelets as 1-flowere 
It re probable that Poiret and Kunth partly described from S. submersus, 
Sauy., an aquatic species whi ch oceurs in Madagascar.

This species is (as many other small Cape Isolepis) generally like 8. selaceus, 
Linn., and S. cernuus, Vahl. The nut is much contracted at the base, where it is 
surrou anded by a wide cireular yellow dise with which it falls,
