Herbariums Mon tagne ist es ihm gelungen, einige fragliche Punkte auf- 

 zuklären. 



Besonders scharf ist die Unterscheidung zwischen Opegrapha culmi- 

 gena Lib. und Opegrapha Epilobii Lib., indem Verf. die erste im Kreise 

 der Opegrapha varia, die zweite Art im Kreise der Opegrapha atra stellt 

 und für identisch mit Opegrapha herbarum Mont. und 0. Tiirneri Leight.

Biatora cinereo-virens Lib. (Crypt. Ard. II u. 115) ist nichts anderes 

 als Squamaria crassa var. Dufoiirei Nyl. ; Parmelia flavoglaucescens Lib. 

 (Crypt. Ard. III u. 216) ist von Candelaria concolor (Dicks.) Fr. nicht 

 verschieden. J. B. de Toni (Modena).

In der Umgebung von Friedrichsberg bieten zahlreiche erratische 

 Blöcke, tiefe Schluchten, ausgedehnte Moore und Buchen- und Nadel- 

 wälder dem Bryologen eine reiche Ausbeute von vielen interessanten, 

 zum Theil auch seltenen Arten, z. B.: Sphagnum Lindbergii, Grimmia 

 Alühlenbeckü, Dicranum viride, Fissidens pusilliis, Trichostomiim 

 cylindricum, Plagiothecinm latebricola, Plagiotheciiim Ruthei, Brachy-

Hay, G. Um Some Features of the Flora of Chathem 

 and New Brunswick. (Trans. R. Soc. Con. VIII, IV. p. 

 125—134. 1902.) 



The region treated of embraces the head waters of the Restigniche, 

 Chepisequit and Tobique rivers in Chathem New Brunswick. 



Along the entire course of the Restigniche, as also in the upper 

 St. Jordan river, Silene cucubaliis is one of the most abundant species, 

 and the author confirms the opinon of Mr. L. Fernald that it was 

 introduced though the medium of the early French settlers who made 

 this river one of their highways. Pimpinella saxifraga, an agressive weed 

 which Covers the highway for two or three miles above F r ed e r i c ton to 

 the exclusion of almost every other plant, is also traced to the influence of 

 the French settlers more than two centuries ago ; Hiimulns lupiilus is found 

 in such situations as to favour the idea of its being indigenous. Tana- 

 cetiim hiironense introduced from western localities and now abundant 

 on the St. Jordan, is beginning to make its appearance on the 

 Restigniche and the same may be said also of Collomia linearis. Hie- 

 raciiim praealtnm or the „king-devil", is rapidly invading new territory 

 and bringing about the extermination of smaller plants, proving to be 

 one of the very worst weeds with which the farmer has to contend. 

 A large number of alpine plants are to be observed on the Restig- 

 niche, especially near the mouths of tributaries which flow from the high- 

 lands of south-eastern Quebec. 



At Chepisiquit lake five plants were found new to the flora of 

 New Brunswick. Rannncnliis circinatus, Myriophyllum alterniflorum, 

 Carex iitriculata var. minor, Potamogeton heterophyllus and Pyrola 

 secunda var. piimila. D. P. Penhallow.
