The more immediate affinity of this species, from the aristate 
squamae and vaginate bracts, is with C. tentaeulata rather than 
G. vesicaria, L. I should infer, from the few specimens I have 
seen, that it is not so common as several of its allies.

This delicate species differs from its allies in its contracted 
inflorescence, narrow triquetrous perigynium, with its long linear 
rostrum and muticous scales. It is a more gracile plant than 
the var. (3 of C.folliculata, the spikes smaller, with fewer and more 
compact flowers. The perigynia in Tab. CCLXVII. that are un¬ 
derscored are from the original specimens of Michaux, in the 
Herb. Mus. Paris. Kunth however quotes the G. rostrata, Mich, 
(from an original specimen), under G. xanthophysa, a species not 
noticed in the Pl. Bor. Americana. I infer that he must have 
been misled by the general resemblance of G. rostrata to that 
plant.

Culmus 2-4-pedalis, obtuse triqueter, firmus, apice scabrius- 
eulus; pars spicas gerens 7-24 poll, longa. Folia 3-5 lin. 
lata, culmo breviora. Bractece vaginantes, latse, in specimini¬ 
bus infiorescentia elongata omnes nisi summa culmo breviores. 
Vaginae inferiores 1-2 poll, longse. Pedunculi 1-5 poll, longi, 
scabri. Spica mascula 6-11 lin. longa, 2 lin. lata, plus minus 
(ssepius breve) pedunculata, interdum spicam supremam foemi- 
ncam vix superans. Spica; feemineae sub 9-12 lin. longse et

pido-aristatse. Perigynium 5^-0-,-,,- lin. longum, l-rViur lin.

Var. /3; culmo graciliori breviori, foliis bracteisque 
angustioribus; spicis longioribus, foemineis laxi-pluri- 
floris; perigyniis angustioribus vix inflatis laxis omnibus 
demum horizontaliter patentibus basi contractis glabris 
vel superne serratis, ore obliquo nunc subintegro ; squa- 
mis ovatis acutis brevioribus muticis vel breve cuspidatis; 
achenio minori.—C. folliculata, Elliott, 545 ; Chapman, 
544. 
Drejer considers this noble species to be the full evolution of 
his Spirostachycc, passing through it into Pliysocarpce. The var. 
/3 is no doubt the C.folliculata of Elliott, as Mr. Curtis remarks 
to me that “ the southern form has short scales.”

pallide viridibus remotis, terminali mascula parva ovali

serte vel exserte pedunculatis; bracteis vaginatis, nisi 
extremis culmo longioribus; stigmatibus 3, brevibus; 
perigyniis anguste subulatis elongatis basi contractis in

bicuspidatis, cuspidibus acutis deorsum reflexis, viridibus
