SOLIERIA AUSTRALIS, Harv. 



Gen. Char. Frond cylindrical, dendroid, formed of three strata ; the me- 

 clullary of longitudinal, anastomosing filaments; the intermediate, of 

 several rows of angular oblong cellules ; the cortical of 2-3 rows of 

 minute, coloured cellules. Fructification: 1, conceptacles immersed 

 in the medullary region, the walls formed of a dense plexus of fila- 

 ments; placenta fibrocellular, central (often at length hollow), sus- 

 pended in the cavity by fibrous emanations from the walls; spores 

 pedicellate, pyriform or ellipsoidal, emitted in fascicles from the pla- 

 centa ; 2, zonate tetraspores, dispersed among the cortical cellules. — 

 Solieria (/. Ag.), in honour of M. Solier, a distinguished French 

 naturalist and algologist.

Solieria avMralis ; frond dendroid (1-2 feet high), robust, excessively 

 branched ; branches alternate or scattered, near together, many times 

 alternately compounded ; ultimate branchlets (1-2 inches long) linear, 

 acute, much attenuate at base, cystocarps half-immersed in the 

 branchlets.
