506 EARLY INTERVALE FLORA Of fiASfERtf tf. S. ROBINSOtf. 



Triosteum perfoliatum, L., occurs at Riverton, and near 

 it is Anemone Virginiana, L. Polygonatum biflorum (Walt.), 

 Ell., which is widely though sparingly reported, prefers 

 the shade, as does Juncoides pilosum (L), Kuntze, while 

 on steep, stony banks Rhus radicans is frequent. Rough 

 places beside the stream are almost sure to contain Senecio 

 obovatus, Muhl., S. Balsamitae, L., and Apocynum canna- 

 binum, L. ; A. androsaemifolium, L., being even commoner, 

 but in richer soil. With them on each of the three Pictou 

 rivers will be seen the leaves of Meibomia Canadensis (L.), 

 Kuntze, the flowers not appearing before the middle of July. It 

 is, however, hardly too much to say that the distribution of 

 almost all of these species is as yet insufficiently known. 



Many plants found in other locations are also frequent here. 

 Such are B dbtnaria dilatata (Pursh), Hook, Vagnera racemosa, 

 L., Myrica Gale, L., and Ranunculus reptans, L., but it has not 

 been the purpose of this paper to enumerate them. 



Why this, the richest and most interesting division of our 

 flora, should have received such scanty attention is, perhaps, a 

 rjuzzle, and even yet not enough is known of the later species to 

 make many general statements. It is, of course, a matter of 

 common knowledge that the most characteristic plant during 

 the middle of July is Lilium Canademe, L., which later gives 

 way to Clematis Virginiana, L., and this in its turn to the 

 Asters, but much more work must be done before the subject 

 can be accurately treated.
