Carex viridula Michx. 

 Common along the outlet of Lake Pleasant. House 7488 August 

 12. Also less frequently along the shore of Lake Pleasant. In 

 both places Carex cryptolepis Mackenzie {no. 7484) is an asso- 

 ciated plant. Both here and at Lake Harris in Essex county search 

 was made for forms intermediate between these two species, which 

 by some authors are regarded as varieties of C. Oederi, native of 

 the Old World, but no intermediate forms were found. The two 

 are very distinct in color of foliage and in the character of the 

 fruiting spikes, C. cryptolepis always being taller and paler 

 green (yellowish green), and when the two grow associated C. 

 c ryptolepis matures its fruit 2 or 3 weeks earlier, but owing 

 to differences in soil, moisture and exposure within short distances 

 along some stretches of these Adirondack lake shores, the maturity 

 of C . viridula often overlaps that ofC. cryptolepis. 



Cyperus dentatus Torrey

 L. Xyris caroliniana Walt., Spiraea tomentosa L. 

 Oxycoccus macrocarpus (Ait.) Pursh, an association of 

 species duplicated with minor variations in places of similar soil con- 

 ditions upon Long Island. 



Myriophyllum tenellum Bigelow 

 Common in shallow water or emersed on muddy banks along the 

 outlet of Lake Pleasant. House 7489, August 12.
