 GEATELOUPIA FILICINA.— ^i/. 



Gen. Guar. — Frond eartilagino-membranaceous, flat, solid ; axis composed of closely 

 interwoven, anastomosing, longitudinal filaments, becoming vertical and dicho- 

 tomous towards the surface, where the cells are very minute, moniliform and 

 compact. Fructification of two kinds, on distinct plants : 1. Favellidia, formed 

 immediately within the stratum of moniliform cells, and communicating with the 

 surface by a minute pore ; 2, Tetraspores cruciate, imbedded among the 

 moniliform cells of the periphery. Name in honour of Dr. Grateloup, a French 

 algologist. 



Geateloupia filicina. — Frond linear, flat, tapering to each end, bipin- 

 nate ; pinnae and pinnulae resembling the main stem, very patent and 

 flexuose.
