The largest of the Psyllophorce, and in some respects allied to 
G. nardina, Fries. In some spikes, flowers with 3 stigmas are 
wanting, and in others they are not so frequent as those with 2. 
None of the specimens afford mature perigynia. Richard did not 
detect the racheola, though I have found it in most of the peri¬ 
gynia I have opened.

Willdenow referred the “ G. stellulata, (3 radiata ,” of Wahl. 
Act. 147, to C. rosea, with a query, and he has been followed more 
confidently by others. Dewey (Sill. vii. 271) notices the position 
of the male florets as inferior in Wahlenberg’s plant, and suggests 
that it may be referable to C. scirpoides, Schk. Probably to that 
plant or to C. trisperma, Dewey. 
I suspect the var. /3 and y insensibly pass into each other. 
Tuckennan describes his G. neglecta as having the male florets 
inferior; but I have his original specimens, which are identical 
with the /3 radiata, Dewey. Schweinitz, from a specimen I have 
of his, considered the var. /3 to be C. retroflexa ; and Muhlenberg 
(p. 220) describes the “ capsula [of O. retroflexa ] margine glabra 
et subscabra,” the last character being applicable only to G. rosea 
and its varieties.
