Jamesoniella autumnalis, which are marked in the Preliminary List 

 with the sign ".—/'' may now be marked with the sign " +." The 

 Maine record for Jungermannia pumila, however, seems to have been 

 based on an incorrect determination and ought to be stricken out. 



Making the additions and subtractions as indicated above, the 

 census of New England Hepaticae would stand as follows: Total 

 number of species recorded, 135; number recorded from Maine, 83; 

 from New Hampshire, 103; from Vermont, 81; from Massachusetts, 

 80; from Rhode Island, 64; from Connecticut, 96; from each of the 

 six states, 35.

TWO VARIATIONS OF CAREX GLAREOSA.

One of the most characteristic sedges of brackish shores of the Gulf 

 of St. Lawrence and of the broad estuary of the River is a small caespi- 

 tose plant which ordinarily passes as Carrx glareosa Wahlenb. There, 

 in eastern Quebec and New Brunswick, the ordinary phase of the 

 plant agrees with most of the arctic material and that of Scandinavia 

 in having plump planp-convex broadly ellipsoid, ovoid or obovoid 

 perigynia which usually taper abruptly to the short beak. A varia- 

 tion of the plant which is less common, and known to the writer only 

 from Cacouna and Bic on the River St. Lawrence differs constantly 

 in having fusiform perigynia which taper gradually to each end. Aside 

 from the plants of Cacouna and Bic the only specimens in the Gray 

 Herbarium with such narrow perigynia are two sheets from Sweden 

 and one from Finland. . . ... , 



As these two phases of Carex glareosa occur in eastern Canada, 

 they are well marked and very constant extremes, each occupying by 

 itself large areas of brackish sandy or gravelly shore. At Cacouna 

 and at Bic the plant with slender jierigynia alone has been found, 

 while at Riviere du I>oup, Dalhousie, Escuminac, Bonne Esperance, 

 and at numerous other places, the plant with short ovoid or obovoid 

 perigynia appears to be the sole representative of the species. 



As already intimated, this broad-fruited plant is generally much 

 better known than the other, and as shown by herbarium-specimens
