Pl. 7: 17. 1902. In tufts of Sphagnum, near Schoodie Lake, 
Maine (A. W. E). New to New England. Probably widely dis- 
tributed in North America but easily confused with other species of 
the ventricosa-group. Until revived by Schiffner the species had long 
been ignored or forgotten by the majority of European writers. L. 
longiflora is closely related to L. porphyroleuca and perhaps repre- 
sents a swamp or bog variety of that species, although Schiffner 
states that he has never seen connecting forms. When compared 
with typical L. porphyroleuca, which grows on rotten logs, L. longi- 
flora is seen to be about three times as large, the difference in size 
being especially apparent in the perianth. Аз a rule the leaf-cells 
have smaller trigones, and their walls are sometimes scarcely thick- 
ened at all. The mouth of the perianth is not lobed asin L. porphyr- 
oleuca but simply minutely and irregularly toothed, very much as in L. 
ventricosa. Unfortunately the Maine specimens are destitute of peri- 
anths but agree in all other respects with those distributed by Schiff- 
ner (Hep. Europaeae Exsic. 138, 139).

aloziella was first proposed by Spruce! as a subgenus under Cephalozia 
and afterwards raised to generic rank by Schiffner? It is not uni- 
versally accepted, even in. Europe, and yet the species which belong 
to it form a group which can be easily distinguished. ‘They are con- 
siderably smaller than in Cephalozia (subgenus Eucephalozia Spruce), 
their leaf-cells also are smaller, and their female flowers are usually 
borne on leading branches rather than on short postical branches. 
The cell-structure of the stems and branches is also characterized 
by being uniform, while in Cephalozia a cortical layer of enlarged 
cells is usually differentiated. The perianth in Cephaloziella, finally,
