glumes, on the other hand, especially in the female plant, are not 
so sharply pointed as in R. Ludwigii, Steud.

This species seems to be variable in the size cf the culms, spike- 
lets, &e., and to a smaller extent in the shape of the bracts and 
glumes; but as on the same specimen instances of these differ- 
ences in form are met with, it is obvious that they do not warrant 
the formation of more than one species.

This species is remarkable for the reduction in the number of 
its parts. In both the male and female plants there is but a 
single flower enveloped by two bracts; there are four glumes only, 
the two stamens in the male plant being placed opposite to the 
two inner glumes.

This species has much of the habit of some of the forms of R. 
8ubverticillatus, but is readily distinguished from it by the much 
more oblong form of the bracts, glumes, the presence of only a 
solitary floret in each spikelet, &c.
