referable; but so. difficult is it to invent a new name applicable to a 
species of Hypnum. with falcate leaves, there was already published. by 
Sullivant, in 1854, in the Proceedings of the American Academy of 
Arts. and. Sciences, vol. iii., a ZZ. arcuatum, from. the Pacifie Islands, 
and a. change of name. being again unavoidable, it is here proposed to 
give the species the name H. Lindbergii. It differs from H. pratense, 
Bry. Europ., in the following particulars :— 
Stems sparingly branched in an irregular manner, without any ap- 
pearance of becoming pinnate, the leaves loosely compressed, ovate or 
ovate-lanceolate, acute, but with a broad point; the margins entire, the 
cells at the angles enlarged and pale, the capsule according to Lindberg 
is on a rather thick seta an inch long, turgid, ovate, when dry, plicate. 
It grows in damp, sandy ground, among thin grass, and not in bogs ; 
it is found in many parts of Britain, being not rare in Sussex, by road- 
sides on sandy soils. The fruit has been gathered but once in Western 
Prussia, by Dr. von Klinggráff, in June, at Wiszniewo. In a barren 
state it was gathered in the Pyrenees by Spruce, and was distributed 
by Schleicher'as H. circinatum. 
H. pratense, Bry. Europ., differs. from the. above, in its irregularly 
pinnate. stems, more compressed foliage, leaves lanceolate, with a narrow 
point, denticulate at the apex, and the enlarged cells in the angles of 
the leaf of the same colour. 
This moss is found, according to the label on the specimen, in the 
: Stirpes Normales,’ ‘in pratis humidis, Vogesi et Alp. Helvet.’, but in 
the ‘ Synopsis,’ M. Schimper, says that he, with Hampe, had gathered 
it in the Black Forest. To this, also, belong the American specimens 
collected. by Drummond in Canada, and by Sullivant and Watson in 
the United States. It would appear that this species is to be sought 
for in bogs,sit certainly grows with Philonotis forstana, Brid., and may 
be expected to occur in Britain.
