ORDER ANTHOCEROTALES. 



Gametophyte a decumbent branching dark green, 

 membranous or fleshy thallus, with irregular pores on 

 the under surface, sometimes also on the upper; cuticu- 

 lar cells mostly small, those of the medulla much larger, 

 each cell with a single large simple chloroplast. Sporophyte 

 enclosed in a cylindric involucre, filiform, forming spores 

 continuously in basipital succession, opening in two 

 valves from above downwards, a persistent columnella is 

 yjresent; the wall often possesses well-formed stomata. 

 Spores globose, variously sculptured on the free surface ; 

 rudimentary elators of 1-3 geniculate cells present or in 

 ieAv instances perfect spiral elators.
