good deal of enterprise due to particular attraction toward such habitats, is 

 required by the collector. The amateur who decides to visit such places must 

 be ready to pass for a crazy fellow, or at the best, for an eccentric. 



Next, there is the difficulty of coming to the right spot at the right time in 

 order to secure these plants to best advantage. If one arrives too early, one is 

 apt to find nothing save water in these ponds or marshy spots; at best only a 

 rudimentary growth of moss will be there. If one comes too late, the grasses 

 and other plants will have choked or replaced the aquatic mosses. The collect- 

 ing of fine specimens, therefore, remains a chance affair unless one lives near 

 enough to the spot to watch the plants and to collect them when at their best. 

 Of course, chances are more favorable in the thick woods, yet some species prefer 

 to grow in the open sunshine of the meadows. In the vicinity of Montreal, the 

 best time to collect Drepanocladi seems to be from the first of May until the end 

 of June; sometimes a bit sooner or later as the spring may be more or less ad- 

 vanced according to the season. 



To the fraternity we beg to submit the following account and partial list 

 of the Drepanocladi more frequently met with in the vicinity of Montreal. We 

 shall use here the divisions and groups recommended by Renauld in his treat- 

 ment of the Harpidia in Husnot's Muscologia Gallica. 

 I. Drepanocladus aduncus Hedw. 



(a) . Group typicus Renauld, comprises mosses of small or middling 

 size, with strongly secund leaves, and with more or less hooked apices to the 

 stems; the hyaline auricles clearly separated. 



Var. tenuis Ren. is a delicate moss in springy or very moist places, 

 of a greenish-yellow aspect. It is rather local, but abundant at Oka, P. Q., in 

 springy rivulets. 



Var. falcalus Ren. forma suhpiligera Ren. is a plant of middling 

 size with a greenish yellow aspect and is quite common everywhere in moist 

 woods and in drying ponds in meadows. It is very near the var. gracilescens 

 which it seems to replace here, and from which it differs in the long, slender apex 

 of the stem leaves. Of late this plant has been called D. suhpiligerus (Ren.) 

 Roth. 



Var. aquaticus Sanio, is larger than the preceding, finely straw 

 colored, and differs mostly in the apex of the stems, which are arched rather than 

 hooked, and in the distant, scarcely secund stem leaves. It is found abundantly 

 in the vicinity of Montreal in wet argillaceous meadows, but seems to require 

 plenty of sunshine and air, and to be rather local, as it has not been reported save 

 as above mentioned. 



(b) . Group Kneiffii Renauld, contains mosses with the leaves scarcely 

 secund, the stem apices straight, not hooked (at least in the following varieties), 

 the auricles not clearly defined. 



Var. polycarpon Blandow, of a dark green aspect has stem leaves 

 short, oval and spreading. It occurs in furrows of argillaceous meadows in the 

 vicinity of Montreal.
