ANDRE2EACE2E. 

 Fig. 1. Generic Character. 



Fruit at the ends of the branches (acrocarpous); stems erect, slightly branched. 

 Leaves in eight rows. Cells (areolce) (a) very small. Flowers {inflorescence) 

 monoicous or dioicous. Capsule (b) split into four valves, united at the top by 

 the lid, which does not fall off (persistent). Calyptra divided on one side 

 (mitriform) , separated from the vaginula, not, as in other mosses, by the rising 

 of the seta, but by the enlargement of the capsule. 



From the division of the capsule, the Andreoeacece are made into a separate 

 order (Schistocarpi) by M. M. Bruch and Schimper.
