mosses on trees. (Botanical Gazette. XXXII. December 



1901. p. 422—423.)

 the north west side, 10*/.. on the north side, 20°/u on the north east side,

 of trees where the greatest amount of moisture is received and held, 

 and this latter factor is considered to be the chief one affecting the 

 location of the alga and mosses. Moore.
