Var. intermedins Bry. Eur., has the stem leaves longer, distant, 

 and appressed; the stems bright yellow and firm. It is of about the same habitat 

 as the var. aquaticns in the vicinity of Montreal, though both varieties seem to 

 be local and rare. 



(c). Group pseudofluitans Renauld. These are the largest mosses of 

 the adunci, with leaves scarcely or not at all secund, the stem apices generally 

 straight and convolute. 



Var. paternus Sanio, ( = D. pseudofluitans Warnst.). This is the 

 coarsest of the group, with deep green leaves, the stem apices upright, convolute, 

 the leaves not appressed nor secund save in dried-up ponds, the leaf apices very 

 long and loriform, and the auricles not distinctly separated. It is common in 

 marshy woods, often with D. capillifolius which it resembles somewhat, except 

 that the costa in paternus is narrow and not percurrent. 



Var. flexilis Renauld. This is more delicate than the preceding* 

 with more the aspect of Amblystegium riparium, but the auricles are very dis- 

 tinct. It is very variable in its aspects; Dr. Roth thought it not a good variety 

 and referred it to Amblystegium riparium, but this view is hardly consistent with 

 the very distinct auricles of flexilis. It is rare and local. 

 II. Drepanocladus capillifolius Warnst. 



(a) . Forma typica Warnst. has very long, narrow leaves, a strong and 

 excurrent costa, and a "woolly" aspect. It is very common in moist woods, 

 ditches, and like places. 



(b) . Var. fallax Renauld, or forma fallax, as Renauld called it first, 

 has the upper stem leaves secund with a hardly percurrent costa, but in the 

 lower older stem leaves the costa is long-excurrent as in forma typica. Indeed, 

 this moss, which is most common in open meadows, seems to be only a form 

 brought about by the sudden and rapid dessication of the ponds and ditches. 

 It abounds in the Montreal meadows and vicinity. 



(c) . Var. brachydictyon Renauld, is a smaller plant, with spreading 

 shorter leaves, an excurrent or percurrent costa. It has been found so far only 

 in a marshy brook at Oka, P. Q.; rare. According to Renauld our American 

 capillifolii are much more variable than the European; the discovery of the 

 forma fallax was a big surprise to him. 



III. Drepanocladus uncinatus Hedwig. This is a very common plant with 

 a sub-percurrent costa and circinate serrate leaves, which distinguish it at once 

 from the preceding species in which the leaf apex is smooth. It is found in 

 rather dry situations, on old stumps and rocks; very common. It must not be 

 mistaken for Hypnum Patientiae (our American form of H. arcuatum) which is 

 without a costa or with a double slender one. 



IV. Drepanocladus fluitans L. The most common form here of the species 

 seems to be the var. Jeanbernati Renauld, a fine-looking yellow moss, with 

 leaves distinctly serrulate (more strongly at apex) and more or less secund, es- 

 pecially at the tips of the stems. It is rather infrequent and local, but occurs 

 in ponds among siliceous rocks at Rigaud, P. Q.
