at the base ; cells narrow, a few only at the angles being en-

 gated, dichotomous, irregularly pinnato-ramulose ; branchlets 

 swollen, curved ; leaves falcato-secund, imbricated, very con- 

 cave, round with an abrupt apiculus, entire, nerveless or two-

In bogs, in various parts of the country. Bearing fruit, 

 but rarely, in spring and early summer. 



Dioicous, forming flaccid, greenish yellowish or chocolate- 

 brown tufts often many inches long. Stems forked, branched, 

 irregularly pinnate ; leaves even, entire, falcato-secund, imbri- 

 cated, large, swollen, very concave, roundish or elliptic with 

 a small abrupt apiculus, nerveless or faintly two-nerved at the 

 base; fruitstalk 2 inches long, even, reddish; sporangium 

 short, oblong, curved, cernuous ; lid conical, pointed. 



A magnificent species, very different from those Bog Mosses 

 to which it bears some external resemblance. It was formerly 

 very abundant about Whittlesea Mere, acquiring many inches 

 in length and occasionally bearing fruit. When growing on 

 rocks, it is sometimes quite procumbent. In some situations. 

 it is almost black, the young tips of the branchlets only being 

 of a tawny green. 



C. Leaves secund, turned upwards. 



78. H. incurvatum, Schrad. ; monoicous ; stem creeping, 

 subpinnate ; divisions curved at the tip ; leaves loosely imbri-
