iosorus rhizophyllus, was found ; hitherto this had only been 

 obtained from the rocky ridges on the south bank of the 

 Ottawa, below the city. In Hull, near Lake Flora, Muhlenhergia 

 Mexicana -a-iuMihus aromatica were discovered. Near the mouth of the 

 Gatineau River Iris ienax was gathered. This is a very rare plant, 

 being a native of the Southern States ; it has never been previously 

 recorded as growing in Canada, and Gray does not mention it as being 

 found in the noi-thern United States. The neighborhood of Lake 

 Wyndiago has contributed Melampyrum Americanum. In the spring 

 Ranunculus Cymhalaria svas found at Thurso growing in low clay meadows 

 in great profusion. This is a curiosity, as its natural habitat is along the 

 sea coast and in the neighborhood of salt springs. A special study of the 

 mai'itime plants which occur in this locality would form an interesting 

 subject for some of our members. Several have already been observed ; 

 some of you will remember the TriglocJdri maritimum var. elaUmi found 

 in the Mer Bleue on one of our excui-sions. Near Hemlock Lake two 

 rare ferns were discovered, Pellcea gracilis and Opliioglossum vulgatum ; 

 here, also, Bapline mezereum was seen growing. This last is not a 

 native of America, but two bushes wei'e found by different members of 

 the club growing wild, one in the woods behind Eideau Hall, and the 

 other in fine fruit among rocks by Hemlock Lake. Some years ago 

 two bushes were found on the top of Mount Royal, Montreal, ftir from 

 any i-esidence or thoroughfare. The bushes were noticed upon more 

 than one occasion, and to judge from their size and their rootstalks 

 were of great age. At Billing's Bridge Viola puhescens var. scabrius- 

 cula and Celtis occidentalis were observed, of the latter only three 

 or four trees grow here, and we are informed by Professor Macoun that 

 with the exception of a grove of six at Belleville, none others are known 

 east of Hamilton. The occurrence of such solitary specimens of full 

 grown trees introduces a subject for speculation. Are they chance 

 introductions, or are they remnants of a previous flora ? Dow's swamp 

 has proved almost an inexhaustible hunting ground. Here was found 

 that great rarity the Ram's-head orchid Gypripcdium Arietinuin which 

 was found in great profusion within a limited area. In the same place 

 two other rare orchids were found in large numbers Hahenaria rotundi- 

 folia and Jlicrostylis monophyllos. It is curious that this last species
