usual generous assistance in identifying or verifying the specimens, 

 and in tlie preparation of this article. 



Aspidium aculeatum, Swartz, var. Brauiiii, Koch. In August, 

 1904, on revisiting the mountain brook which comes down the north 

 side of Greylock, where I had previously found Hydrophyllum Caiia- 

 dcnse, I came across several plants of this fine fern. As far as I can 

 discover, it has not hitherto been reported from Massachusetts. 



Aspidium simuiatum, Davenport. In September, 1904, I found 

 this interesting fern not uncommon in the swampy woods bordering 

 ponds in Becket and Otis. I have little doubt that on further search 

 it will be found in similar situations in other parts of the county. 

 Most of the New England records hitherto published have been from 

 near the coast. 



Potamogeton confervoidcs, Reichb. {P. Tuckermani, Robbins). 

 Grows in Lake Undine on the Dome at an altitude of 2000 feet. 

 The only other known station for Massachusetts is in Uxbridge, 

 where it was collected by Robbins. It is found at high altitudes in 

 New Hampshire and Vermont, and in several stations in New Jersey. 

 It is recorded in Bennett's Plants of Rhode Island (p. 42) but no 

 locality is given. 



Eleocharis intermedia, Schultes. This species has been collected 

 in northern Maine, in Vermont and in Salisbury, Connecticut but 

 has not, so far as known, been reported for Massachusetts. I col- 

 lected it in Pittsfield in 1902. 



Scirpus lineatus, Michx. Collected at Stockbridge in 1902. It 

 has been recorded from Middlebury and Bristol, Vermont (Rho- 

 DORA, vi, 139), but not so far as I know from the other New Eng- 

 land states. 



Eriophonim polystachyon, L., var. Vaillantii, Dub}-. Mr. M. L, 

 Fernald collected this cotton-grass at Sheffield in 1902. The atten- 

 tion of American botanists was first called to this variety by Mr. 

 Fernald in Rhodora, iv. 82, where he records material collected by 

 Dr. Fellows near Portland, Maine. 



Carex aenea, Fernald. Occurs on rocky ledges on the Dome 

 Sheffield, and in Glendale (vid. Rhodora, iv, 227). 



Carex Bebbii, Olney. Occurs in bogs and low ground in Pittsfield, 

 Glendale and Sheffield (vid. Rhodora, iv, 228.) 



Carex intumescens, Rudge, var. Fernaldii, Bailey. Occurs not 

 infrequently in wet woods.
