One sessile pistillate spike ovate and at € 
staminate, with two or three radical peddntied bearmg each 
a pistillate spike, as in the common variety. 
As this variety is found growing on the same root with the 
other, there can be no doubt about it, although the fig. in 
Schk. and all the descriptions given before that in this Jour- 
nal, Vol. X. imply that all the pistillate spikes are on radical 
peduncles. This variety too is very common.

As Wahl. had established a ston 8 bes the name of C. 
_subulata, it became necessary to change the name given by 
Mx. to this species. But as Mr. Nuttall had given the plant 
another name ee pecs requires that this species 
should be called C. Collins Though I have never seen 
the termination of the fruit so came aia there can be 
no doubt that Mr. Nuttall respected the plant which I called
