PLATE 85 



Fig. 1. Dendrymcnia flabellifolia. The major portion of a 

 clump showing the base, the long irregular denuded 

 lower axes, and the somewhat pyramidal aspect of the 

 foliiferous portion above. The forking of the blades 

 shows fairly well, but the spiral arrangement of these 

 on the axes does not, nor are the tetrasporangial sori 

 distinguishable. I. Isabela. x 0.4.
