CHYLOCLADIA CLIFTONI, Harv. 



Gen. Char. Frond terete or subcompressed, rarely nodose-articulate, 

 alternately decompound, tubular; periphery formed of angular cells. 

 Fructification : 1, conical, external .conceptacles, opening by a pore, 

 containing a favelloid nucleus, surrounded by a web of filaments ; 

 2, triangularly parted, scattered tetraspores. — Chylocladia (Grev.), 

 from xy\o<;, juice, and /cXaSo?, a branch ; the tube contains watery 

 fluid. 



Frons teres v. subcompressa, nunc nodoso-articulata, alterne decomposita, tubu- 

 losa ; tubo succo aquoso repleto ; strato periplierico ex ceilidh rotundato- 

 angulatis contexto. Fr. : 1, cystocarpia simplicia, intra per icarpium extern inn 

 conicum carpostomio demum apertum inclusa, reticulo arachnoideo cincta ; 

 2, tetrasporce triangule divisce, sparsce. 



Chylocladia Cliftoni ; frond delicately membranous, rose-coloured, full 

 of slimy gelatine, nodoso-articulate, trichotomous or umbellately 

 branched; ramuli springing from nearly every node; lower inter- 

 nodes clavate, 4-5 times as long as broad ; upper obovate ; ultimate 

 ellipsoidal, obtuse at both ends.

 articulato-constricta trichotoma v. umbellatim ramosa ; ramidis fere ad sin- 

 gula genicula egredientibus saepe numerosis ; articulis inferioribus clavatis dia- 

 metro 4<-5-plo longioribus, superioribus obovatis, ultimis ellipsoideis utrinque 

 obtusis.

Hab. Cast ashore at Fremantle, Western Australia, G. Clifton, Esq. 



Geogr. Dtstr. As above. 



Descr. Boot a disc, with clasping fibres. Frond 3-5 inches long, 1-2 lines in 

 diameter, constricted as if jointed throughout, trichotomous or dicho- 

 tomons, somewhat fastigiate ; the upper branches frequently umbellate or 

 crowded and fasciculate ; all the axils very wide and obtuse. In some 

 specimens the principal divisions are beset with crowded or fascicled ramuli, 

 consisting of two or more articulations. The internodes or articulations of 

 the larger divisions are clavate, and often 5-6 times as long as broad ; 

 those of the smaller branches are broader in proportion to their length ; 

 and the ultimate are scarcely twice as long as broad, and regularly ovoid. 

 Xone are stipitate, the neck or node being generally half as wide as the 

 internode. The substance is very thin and delicate, soon decomposing in 

 fresh-water. "When fresh, the tubular frond is full of slime, and in drying
