506 EARLY INTERVALE FLORA OF EASTERN N. S.—ROBINSON. 
Triosteum perfoliatum, L., occurs at Riverton, and near 
itis 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 Habenaria 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 
puzzle, 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 Liliwm Canadense, 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.
