This plant was considered by Nees von Esenbeck to be refer- 
able to R. Ludwigii, Steudel, and, in accordance with that opinion, 
is so named by Nees himself in Dr. Sonder's herbarium. A com- 
parison of the plant, however, with an authentie specimen of R. 
Ludwigit, Steud., in the Fielding herbarium, shows that the two 
plants, though very closely allied, yet belong to different species, 
or at least must be considered to do so till further evidence may 
supply intermediate links between the two. The present species 
differs from R. Ludwigii, Steud., in the larger size of all its parts, 
in the many-flowered male spikelets, in the more acuminate form 
of the bracts, in their shorter points and closer disposition. The
