ful but very rare H. fimbriata. Here too grows Iris prismatica, 
and on alittle point projecting into a pond Hierochloé odorata. 
In the lowland woods, among other interesting plants, Viola ro- 
tundifolia is frequent, and on higher ground Viola pedata. In 
this same valley a few specimens of Pentstemon levigatus have 
been found, while P. /zrsutus has not been seen, though it occurs 
afew miles to the eastward. Drosera rotundifolia occurs here, 
though not abundantly. Its habit is perhaps worth notice. It 
Srows on the surface of a smooth. ledge over which a little water 
is continually oozing, but there is very little soil. 
In a swamp on the southwestern slope of Tashua Hill Siam 
Carsonii grows in great abundance, almost choking the brook in 
some places. It is confined to the bed and immediate banks of 
the stream. The locality is at present in danger of extermina- 
tion by the dam of the new reservoir, which is in process of con- 
struction. 
On the wooded ridge west of Tashua is a locality where 
Woodwardia areolata is abundant (over a small area). With it 
Stow Aster acuminatus, Pyrola elliptica and P. rotundifolia, the 
two Chimaphilas and numerous other plants of interest. Not far 
distant Botrychium lanceolatum has been found, and still farther 
west is a swamp which is a favorite haunt of Calla palustris, and 
in the same vicinity Carex umbellata was found by the roadside, 
though recent search has failed to reveal any more specimens. 
Following down Mill River some four miles, most of the way 
through rich collecting ground, we come to Samp Mortar Rock, 
4 much-visited and very picturesque locality. Here in the stream 
one can find Utricularia vulgaris and U. intermedia, the latter 
creeping among the stones, and sending its naked bladder-bearing 
branches down to the water below. In the swift places the 
stones are covered with mats of Podostemon ceratophyllus, which 
‘May be seen in fruit in August. In the sand along the edge of 
the stream is Callitriche Austini, while in the river here, as else- 
where, C. verna is not uncommon, though not assigned to New 
England at all in the last edition of the Manual. Back from the 
tiver, onthe sandy slopes in an old pasture, are several large patches 
of Rubus cuneifolius. Further up in the edge of the woods are Or- 
alis violacea, and Aralia hispida, and in the clefts of the over-
