Radix csespitosa, fibrosa. Culrnus l-l^-pedalis, gracilis, 
debilis, reclinatus, obtuse triqueter, Isevis, vel superne tantum 
inter spiculas scabriusculus. Folia sub lineam lata, culmo 
longiora vel breviora, mollia. Brae tea; 3 ; inferiores elongates; 
infima (nunc pedalis) spicam longe superans ; superiores breves. 
Spica 3-8 poll, longa. Spicules ovales vel elliptic®; infima 
12-5 poll, remota ■ summa quandoque mascula vel sterilis.

pallide fulvo-punctulatum. Achenium yy lin. longum, yy lin. 
latum, oblongo-ovatum, basi productum, plano-convexiuscu- 
lum, basi styli decidua crassiore.

vis obsoletis, 1 t 2 q —A j lin. longis ( Royle , etc.), et perigyniis 
angustis lin. latis, achenio plus J-j lin. lato [Hooker). 
Koch, Andersson, and Lange describe the lower spicula as oc¬ 
casionally compound, and Reichenbach figures a variety with a 
creeping root. I have not seen any American specimen of this 
common European plant, but Gay says it is found in Newfound¬ 
land, and the ‘Flora Rossiea’ reports it as a native of Sitcha, 
though Bongard does not include it in his list.

At page 112, Tab. CCCLY., I described and figured the C. la- 
cu.fris, Willd., referring it to the C. riparia, Curtis, hut omitted 
to say that the specimen figured was from Rhode Island, and to 
allude to the European and Asiatic habitats of the species. In 
Europe it is found from Norway, Sweden, Denmark, to Constan¬ 
tinople ; and in Asia, on the Caucasus and Altai. Lange, 140, 
and Bromfield, 575, allude to a variety with a variable distribu¬ 
tion of female florets on the solitary male spicula, like the n. 1 
I have figured from Switzerland, which I owe to the kindness of 
M. Spacli; but I have not met with any description which applies to 
the n. 2, from the banks of the Leet. Eor, though De Candolle (El. 
Eranc. vi. 297) has a variety “ spicis omnibus femineis he says 
nothing of their form, which is so peculiar in the specimens 
figured from my own and Professor Balfour’s herbarium.
