hyemale, var. affine, which prefers loose soils, especially on terraces 

 and hanks near streams, has about the same northern limit as B. 

 simplex, but without the outlying station: though it. occurs at Pem- 

 broke in Washington Co., it has not been found near the coast be- 

 tween that point and Wells.

This group corresponds exactly with that of the same name in 

 our last report. Of the species in sub-division A, Equisetum scir- 

 poides reaches its southern limits at Southbridge, Mass., and in 

 northwestern Connecticut. The two Lyeopodiums reach Cape Ann, 

 the central highland of Massachusetts and western Connecticut; 

 L. annotinum var. acrifolium is found also at Union, in the eastern 

 highland of Connecticut. It seems to he much less common in 

 Maine than typical /,. annotinum, and is not recorded by St. John 

 and Nichols. 



Of sub-division B, Lycopodium annotinum, var. alpestre is known 

 in our area only from Mt. Lafayette, /.. clcnatum, var. monostackyon 

 only from Mt. Washington and L. Selago, var. patens only from Mt. 

 Mansfield. Typical L. Selago 9 is chiefly confined to mountainous 



IJ Including vur. apprettum.
