194 Report of the Brown-Harvard Expedition. 



B. MOSSES AND HEPATICS. 



Note. — The examination of these plants is still incomplete. Mr. 

 Collins reports on them as follows: " Specimens collected (mostly 

 without fruit) 114; specimens determined, about 85; species deter- 

 mined, 29. Thirteen of these have already been reported from sev- 

 eral localities on the Labrador coast, Five of them have been 

 reported from one locality only. Of the remaining eleven, two (Di- 

 cranum fuseescens, Polytrieum piliferum) have been indefi- 

 nitely reported from " Labrador;" five (Brachythecium sale- 

 brosum, Conostomum boreale, Dicranum Bergeri, Pogo- 

 natum capillare, Polytrieum .commune,) are very common 

 throughout North America and are reported from both Greenland 

 and Newfoundland, and it would be very surprising if they did not 

 occur on the Labrador coast, although there is no previous record of 

 them; three others are entirely new : Mnium. punctatum. elatum. 

 is known in Miquelon, but the type has been reported also from the 

 Labrador coast; Barbula ruralis is known previously only from 

 further north and west ; Splachnum Worm.skjoldii seems to be a 

 very good find, having ;been known heretofore only from high north- 

 ward—Smith Sound (78°— 82° N.), Greenland, Norway, Lapland, 

 Spitzbergen. and N.Asia; and finally one (No. 26b, see below), if a 

 variety of Pogonatum urnigerum, is here found much farther 

 north and at a higher altitude than previously known. Most of the 

 undetermined specimens are apparently more or less common species 

 (or duplicates), although, from a hasty perusal, a few of them may 

 prove interesting, as I cannot place them without further study." 



For the detennination of previously recorded localities, "Paris: 

 Index Bryologicus (1894-1900)" has been consulted, in addition to the 

 authorities already referred to. Specimens recorded below merely as 

 from the " Atlantic coast of Labrador" were gathered in a variety 

 of places and seemed to the collector to be so common and widely 

 distributed that no more definite local references were made.
