104 Rhodora [May 



ward Island. Wiegand treats the species as belonging to the Pied- 

 mont and Alleghenian regions from Vermont and New York to 

 North Carolina, there occurring chiefly in bogs. Its abundance in 

 Nova Scotia and Prince Edward Island on either damp or dry soils 

 suggests that it may be a Canadian species which southward takes 

 to the bogs. 



We were gradually growing into the habit of spending all our 

 mornings in the barn caring for the presses and on July 13 it was, 

 therefore, afternoon before we got away, all five of us by automobile, 

 with the avowed purpose of going inland to Carleton or to Kempt- 

 ville. Not far from Yarmouth we were tempted by a little pondlet, 

 dignified by the wholly undistinguishing name Lily Lake, to stop 

 long enough to "size up" the place, a bog-pond with quaking bushy 

 margin, where we collected for the first time Rosa 2>(ihistris Marsh, 1 

 and deep in the spruce thicket immature but thoroughly character- 

 istic Thdypterit nmviata (Davenp.) Nieuwl. (Aipidiwn simvla- 

 him), 2 heretofore unknown east of southern Maine but afterward 

 found to be quite general on bog-barrens, in spruce swamps or in 

 alder-thickets as far east as we worked in the Avalonian formation 

 (Port Mouton and Broad River). This southern fern was growing 

 with its regular southern associates, Carex athwticu and C. Hoivei, 

 and nearby were the ubiquitous Carex bullata, var. G recti ei, and 

 Thelyptcris Boottii (Tuckerm.) Nieuwl., 3 which soon proved to be a 

 common fern. 



The next stop was a brief one, to prospect a little about the shore 

 of Greenville (or Salmon) Lake. The water was high but Isoefes, 

 as usual wherever we went, was already well fruited; Xyris carolini- 

 ana was becoming really recognizable; and, abundant in the boggy 

 thicket, where in Maine or New Brunswick we should expect Galium 

 trifidum, was the larger and smoother G. tincturiuin, again a southern 

 species not previously known northeast of Massachusetts. 



We had gone but a short distance up the west bank of the Tusket 

 River when, at Tusket Falls, we spied an extensive tidal flat, one of 

 those "demd damp, moist, and unpleasant" stretches of ooze and 

 slimy mud which is always sought by the properly enthusiastic 

 field-botanist, for here there is good collecting. The tidal flats at 

 Tusket Falls do not equal some in New England nor those on the
