CORALLINE VER.Î: JAPONIC^. 



OORALLINAE VERAE JAPONICAE. 



Amiphiroa, l.amx. 



1. Amphiroa valonioides, sp. nov. 



rj. I. %. 1—8 : ri. IV. fig. 1. 



Fronde pulvinato-caespitosa; ramis paucis, patentibus, lateralibus, 

 pseudo- sympodialibus vel irregulariter dichotomis ; articulis exacte 

 cylindraceis, equicrassis, 0.2-0.3 mm. latis, 0.6-0.8 mm. longis, 

 apice obtusis ; geniculis superioribus obsoletis, inferioribus articulorum 

 diametrum leqiiantibus ; conceptaculis verrucœformibus. 



The articuli are homogenecjnsly cylindrical, measuring 0.2-0.8 

 mm. in diameter and 0.6-0.8 mm. in length, becoming a little thicker 

 and shorter toward the base. l^ranches are few in number and 

 generally proceed laterally from the top of an articulus without 

 geniculum, in a sympodial manner. 



The conceptacles are ellipsoidal warty protuberances, often cover- 

 ing the whole surface of an articulus. The genicula are very 

 insignificant especially at the upper portions, owing to the durability 

 of the cortical part after they have been completed (Pi. I. fig. 3). 



I can not not find an}- appropriate description referable to the 

 present plant, although it has some resemblance to Amphiroa setacea, 

 Kütz : but the character " ramulis oppositis plerumque tuberculatis 

 patentibus " is hardly apphcable to our plant. 



Found in the sublittoral reo^ion at the coast of the Prov. of
