ant in maritime pools southward quite to tropical America. The 

 rocky shore, too, had maritime plants: Samolus floribundus in wet 

 crevices, Teucrium canadcnsc, var. littorale, and Juncus articulates, 

 var. obtasatus. West of Eel Lake w r e came to an extensive, dry, 

 Polyiri chum -covered barren with meagre enough vegetation but 

 with Habenaria blephariglottis and Ilex glabra abundant, even domi- 

 nant in some areas, Carex aenca, which we had had only from Spring- 

 hill Junction, and a good number of Panicums. The brackish 

 marshes along Abram River contained extenisve sloughs full of Scir- 

 pus Olneyi, which, when we first got it at Sand Beach, had seemed a 

 thrilling discovery; a small quagmire at the border of the barren 

 was full of Utrieularia geminiseapa Benj. (U. clandestina); and a wet 

 cart-road was bordered by Juncus acuminata.? and /. marginatus 

 (one of the long discredited plants of Lindsay's Catalogue). 



When we returned to Belleville station Long was closely studying 

 the railroad-bed — to find more of the curious little weed with short, 

 club-shaped scapes and tiny dandelion-like heads, Arnoseris pusilla. 

 The plant, a wanderer from Europe, is well established at this point 

 and is likely to spread, since no one bent on gathering a bouquet 

 will disturb it. Long and Linder had got into dry barrens where 

 Corona abounds but most of the lakes had hopelessly inaccessible 

 shores, flooded high into the bushes and bordering swales where, 

 floundering thiough the acres of Sparganium americannm or Pontr- 

 deria one would take his life in his hands (or more likely consign it 

 to the waters). They had succeeded, however, in finding enough 

 accessible shore at Clearwater Lake and at another, called Minnigo- 

 bake, to secure Cy penis dcntatus, which we had not previously col- 

 lected, Ophioglossum vulgatum, occurring in cobble-beach as at Cedar 

 Lake, MyriophyUum tenellum and Subularia aquatica again and, of 

 course, Utrieularia subulata. The most striking discovery, however, 

 was that of Juncus subcaudatus (Engelm.) Coville & Blake, 1 in the 

 wet border of a spruce swamp. This plant, treated in the 7th edi- 

 tion of the Manual as a southern variety of ./. canadensis (ranging 

 north to Rhode Island, although Long and I have subsequently got 

 it on Cape Cod), we found through the rest of the season to be a thor- 

 oughly characteristic denizen of boggy woods or openings in spruce 

 swamps from Digby Neck south through Yarmouth County thence
