In the proliferous perigynia, from which some of the male spikes 
and the ramuli of the female ones issue, we occasionally find not 
only the exserted axis bearing florets, but the usual female floral 
organs, showing that the racheola, so often met with within the 
perigynium of other species, is a rudimentary axis. This fine 
species belongs to the Vesiearice.

The oblique emarginate orifice of the perigynium and the el¬ 
liptic papillose achenium distinguish this species from C. hys- 
tricina. I have never seen specimens from the southern states. 
The one in Elliott’s herbarium, Mr. Curtis tells me, was from 
Muhlenberg. Eendler however found it in Venezuela with the 
orifice of the perigynium entire. I have figured a perigynium 
from his specimen at the lower corner of Tab. CCLXXVII. I 
have observed the same oblique entire orifice in some of the spe¬ 
cimens from Dr. Barratt from Connecticut.* The var. ft has the 
culm 4-15 inches in height, the female spikes 4-12 lines long, 
3-4 lines broad. It was sent to me by Mr. Sullivant and Dr. 
Chapman. The other variety is possibly a hybrid between G. ten¬ 
taculata and G. lupulina, for the achenia are abortive. It may be 
Schkuhr’s G. G. G., judging from the number of the nerves on 
the perigynium, and the absence of the achenium in the figure. 
It differs from G. tentaculata in the characters I have pointed 
out. It differs also from G. Halei and from C. lupulina in the 
squamae; from the last also in the more divergent spikes and 
perigynia, narrower and shorter bracts, and narrower leaves. 
The absence of the achenium deprives us of the clear evidence 
it would afford as to the affinity. As the existence of hybrids in 
Carex is doubtless, this plant, as well as G. Sullivantii, is de¬ 
serving of attention.

* In Jameson’s specimens from the Andes of Quito, the orifice 
of the perigvnium is oblique and bifid. The colour of some of 
the perigynia is purplish, and the lower spike in one specimen is 
compound at base, having two small abortive spiculse.
