subexserte pedunculatis; fructibus ovato-conitis acuminatis 
rostratis bidentatis maximis glaberrimis nervosis inflatis di- 
vergentibus, squama ovato-cuspidata triplo longioribus. 
Culm i2—24 inches high, acutely triangular, scabrous 
above, leafy ; ieaves linear-lanceolate, rather rough, nerved, 
glabrous, shorter below, upper ones surpassing the culm; 
bracts long, leafy, nerved, much surpassing the culm, with 
short sheaths; staminate spike single, pedunculate, oblong, 
slender; staminate scale long, lanceolate, tawney ; pistillate 
spikes 1-3, generally two, approximate, erect, with inclosed 
and short peduncles, the highest nearly sessile, the lowest 
sometimes remote and exsertly peduneulate, three to nine 
flowered but generally about six; fruit ovate, conic, rostrate, 
two-toothed, much inflated, nerved ; pistillate scale ovate, 
cuspidate, about one-third as long as the fruit. Colour of 
the whole plant dark green——very glabrous.

Flowers in May—grows in marshy situations—common. 
From the description of this species by Linnzus, which has 
been repeated by most of the authors until the publication of 
Muh.’s Gram., it would seem that the specimens first sent to 
Europe had only one pistillate spike. Hence the descriptions 
in Willd., Pursh, Eaton, Rees’ Cyc. &c. are defective, as 
there is generally more than one pistillate spike. The writer 
in Rees’ Cyc. has noticed this disagreement of the descrip- 
tion with the fig. of the plant in the Linn. Trans. The rep- 
etition of the defective description of Willd. by Pursh, shows 
with how little attention Pursh had examined this species. 
Muh. was of the opinion that C. intumescens, Rudge, might 
be the C. folliculata, L., in which he is followed by Pursh. 
But in Rees?’ Cyc. the two are described as different species, 
though there seems to be no essential difference between 
them. As the writer appears to have had the means of 
comparing the fig. of Rudge with that of C. folliculata, it may 
be inferred that the two, if varieties, are very remote. By 
those familiarly acquainted with C. folliculuta, the point 
could be determined upon a moment’s inspection of the fig. 
of C. intumescens, in the Linn. Trans. This fig. however, I> 
have never seen. There can be no douot that the C. lurida, 
Wahl. is not, as is supposed in Rees?’ Cyc., the C. intumese 
cens, Rudge; but is the C. lupuling, Muh. Of this, if it
