uncommon. When peduncles occur, they arc sparhigly 

 clothed with slender bracts that are nearly like the 

 leaves in shape and size. In many cases but a single 

 cone is borne on the peduncle, but in the majority the 

 peduncle forks near the summit, each fork ending in 

 a cone. At maturity the sporophylls appear to be 

 reflexed. 



Lycopodiiini Sitchcnsc is found in the United States in 

 Maine, New York, Idaho, and Washington, and extends 

 northward to Labrador and Alaska. It has not been 

 half a dozen years since its claims to specific distinction 

 have been seriously considered, and therefore compara- 

 tively little is known about it. It will doubtless be 

 found to be more abundant in the northern tier of 

 States than it has thus far been found to be. Owing to 

 its northern habitat it is likely to occur upon mountain 

 tops only in the southern parts of its range. 



The Tree Club-Moss. 



It is not the tree-like proportions of the tree club-moss 

 [Lycopodiuni obscuriitn) that have suggested its common 

 name, but rather its habit of growth and general appear- 

 ance. The upright stems are so much like miniature 

 pine trees that an)' one finding the plant for the first 

 time is likely to identify it by associating its appearance 

 with the idea suggested by the common name. 



The tree-like aspect of this species is heightened by 

 the fact that the main stem is deeply underground, and 

 the branches arising at some distance from one another 

 seem to be different plants instead of several branches of 

 one individual. Of all our lycopodiums, this species has 

 a main stem that is most like a rootstock, being slender,
