 L. sahincefoUum, Willd., L. cliamcBcyparissias^ A. Braun ; 

 with branches more erect and fascicled. Prof. Asa Gray remarks : — 

 " The typical form of L. comjjlanatum, with spreading, fan-like 

 branches, is abundant southward (in N. States), while northward 

 it passes gradually into the var. sabinoefolium.^^ I have only one 

 rather imperfect specimen of the European L. cJiamceci/parissiaSj 

 collected at Bonn on the Rhine, by my friend Professor G. S. 

 Blackie, which does not differ in the branching from ordinary 

 Canadian forms of L. comj)Ianatum. It appears to be quite a 

 common species in the States, for I have it from a great many places. 



Selaginella. 



S. spinidosa, A. Braun. — Small, prostrate, leaves lanceolate, 

 acute, spreading, spinosely toothed ; fertile branch stouter, ascend-
