By the way I have here to give the illustrations of fructified 

 portions of Spyridia filamentOSa Harv., which I have missed 

 when I illustrated that species in Vol. Ill, no. i, PI. CII., fig. 



5-14- 



Tctrasporcs are formed from genicular cells surrounding the 

 joints of ramelli and one or two spores are observed at the same 

 joint. Antheridial cells are formed from genicular cells of ramelli 

 and afterward a dense cluster is formed by their confluenting 

 together over many articulations. Cystocarps globular attached 

 to the side of branches or branchlets, with a short and very 

 slender pedicel.
