336 | Mr. J. E. Bicneno’s Observations 
ries so — according to the soil in which it grows, as to render 
it difficult to assign the limits between it and £, and some of the 
foreign species.. Many botanists indeed have considered the bog 
variety as a distinct species. Ray, Dillenius, Sibthorp, Withering, 
and the French botanists are of this opinion. On the other hand, 
Linneus, Willdenow, Curtis, and Sir James Smith regard it only 
as a variety. To the latter opinion I assent after much examination. 
Sir James Smith, Flor. Brit. 386. in his 8 has only described that 
variety growing in bogs with a conglomerate head, composed, as 
Ray says, * ex pluribus veluti globulis coacervata;" but mine 
includes not only. this, but another, equally common, the y of Lin- 
nzus, where the little heads stand on long footstalks, growing 
something like the one figured by Linnzus, Flor. Lap. t. x. 2., and 
yettotally distinct from it. Sir James Smith is at a loss to recon- 
cile Ray's synonyms; but all the figures to which he refers are 
without doubt intended for the plant in its pedunculated state. 
Desvaux has made Linnzus's 8 and mine a new species, which he 
calls Luzula erecta, as above quoted. I cannot, however, agree 
with this arrangement, being quite satisfied that Linnæus’s plant, 
Flor. Lap. l.c., is a good species, and is to be known by the 
leaves being narrower and nearly destitute of hairs, the stems 
compressed, and spikes umbellated. Wahlenburg, who has given 
it a place in his valuable Flora, calls it Juncus pallescens, with 
this definition: “ foliis planis, culmo compresso, spicis umbella- 
tis oblongis pedunculatis patentibus, bractea foliacea.” I have 
not observed it in any collection of British plants, though it is 
very likely to be a native of the northern mountains.
