on the Genus Juncus of Linneus: | 323 
Stem a little bulbous at the base, decumbent, striking root at the 
“joints, generally a few inches in height, cylindrical, fistulous. 
Leaves at the root filiform, articulate; those of the stem larger, 
subulate, knotty-jointed, brittle, springing from a large scariose 
sheath. Flowers in a corymb, as if proliferous, fasciculato-ver- 
ticillate, light-brown. Calya-leaflets lanceolate, acuminate, stri- 
ated, rigid. Capsule obtuse, light-brown, not longer than the 
calyx, somewhat shining, mucronate. 
Though I am not enabled to ascertain many modern synonyms 
with certainty for this common plant, I feel confident that it will 
be found on examination to be a good species. ‘The French bo- 
tanists give it the above name in their herbaria. Rostkov, Will- 
denow, and most others seem to have considered the J. uliginosus 
of Smith and this to be the same. Sibthorp’s description of 
uliginosus corresponds so nearly with it, that I think he had an 
eye to it in drawing up his specific character—* Floribus fasci- 
culatis, fasciculis proliferis, foliis setaceis articulato-nodosis." Wi- 
thering's definition is also applicable to this. Haller’s no. 1321 
is most likely intended for it—* Foliis sessilibus articulatis, pani- 
cula simplici, glumis aristatis.” And Parkinson’s figure 1189 
tolerably corresponds.
