CORALLINE YEUM JAPOXICiE. I3 



jios\s oi A. düatala, und " tr.insversim et «nbtiliter zonatis " in that 

 of A. (jülaxanroides (Spec. AJg. Lc.) Our plant has always plain 

 transverse zones and mncli more a])plies to the latter than to the 

 former. 



]\Iartens enumerates A. (jalaxanroides in the list he. He does 

 not acknowledge the reduction of the species hy Areschong on the 

 ground that his plant lias the articuli ''alle flach und ziemlich gleich 

 breit," while in A. dilatata ''sind die nutersten Glieder stielrund." 

 I could not und anv species of AwpJiiroa whose articuli were flattened 

 already at the base, provided that it had been a complete specimen.

Fronde 1.5-3.Ü cm. alta, decumbenti saepe erecta, ima basi 

 subtereti, superne compressa, di-trichotoma ; articnlis iniimis subtere-

 superioi'ibus ; conceptaculis numerosissimis. 



11ns species stands very near to Aiiijdiiroa dihitaUi, Lamx. But 

 the articuli are ahvays much more rounded and in every proportion 

 small. The attenuity of the terminal articuli. ending hnally in a 

 blunt point, is its special character. Conceptacles are generally found 

 on the shaded surface, but in the erect form on lioth surfaces.
