The more important range-extensions and observations of the 

 summer arc enumerated below; as in the previous enumeration the 

 species new to Canada (37) are marked **, the additional ones (25) 

 new to Nova Scotia.* 



Woodwakdia virginica (L.) Moore. Besides occurring as already 

 reported, in Yarmouth and Queens Cos., the Chain Fern is character- 

 istic of boggy shores and thickets northeastward through Digby Co. 

 to Annapolis Co. (near Lamb's Lake; near Liverpool Head L.) It 

 is frequent throughout Shelburne Co., sometimes, as at Harper Lake, 

 reaching a height of 1.7 m. 



W. A.REOIATA (L.) Moore. Rather frequent in the Tusket Valley, 

 north to Pearl Lake, Kemptville and east to St. John (Wilson) Lake; 

 splendidly developed in the sandy alluvium and lake-margins of the 

 Roseway River system, Shelburne Co., plants from near the head 

 of .McKay's Lake, Middle Ohio, measuring 7 dm. high. 



Athyrium acrostichoides (Sw.) Diels. Rich woods on north 

 Mt., Belle Isle, Annapolis Co. 



A. A.NGUSTUM (Willd.) Presl, var. elatius (Link) Butters. Swampy 

 woods on slopes above Lahave River, Bridgewater, Lunenburg Co. 



Thelypteris simulata (Daw) Nieuwl. Reported from Yarmouth 

 to Queens; but now known eastward to Lunenburg Co.: knolls in 

 boggy thicket by Wile's (Oakhill) Lake. Extending north in Yarmouth 

 nad Shelburne Cos. to Kemptville and to Jones Lake, Roseway River. 



Thelypteris Boottii (Tuckerm.) Nieuwl. At various stations in

 habitats in all acid areas in the province. Unrecorded stations are, 

 for Digby' Co.: forming a close turf with Vaccinium Oxycoccus and 

 Rynchospora alba at peaty border (many acres) of Tibert Lake, Free- 

 port, — this, probably the most extensive station known for the 

 species, within a few rods of the Bay of Fundy; wet sphagnous 

 hollows in peaty savannah along The Brook, Central Grove. Shel-
