.Inly, i'M.:.i YEN DO— NOTES OS ALd.K NEW To JAPAN, W 255 



Cotton reported this s])cclcs from Wonsen, Corca, and Wei- 

 liai-wei, China. Ivxamininsr tlie material in my hand, I lomid 

 the s])ecics ])retty eommon on the Japan Sea side ol our country. 

 T mcjilioii. however, that there is another spceies ol Gclidium 

 on our coast which has a ver\' similar ap])caranee of frond with 

 the ])rescnt but cpiite differinc;- in the shape of stichidia. It is a 

 doubt held for a long time by me that various species of Gelidhim 

 mnx assume tlic general aspect of frond approaching to G. hiti- 

 folium Born, according to the condition of place where they 

 grow. Still I mention the occurrence of this species within oiu" 

 boundary as it is more or less fixed form. In Japan such a 

 broad form as figured in Phyc. Brit., pi. 53, fig. 8 is hitherto 

 unknown. 



Locality. Yangeshiri Island (!); Oshoro (!); Hakodate (!);

We have a well-defined form of Gelidium on the Pacific coast 

 of middle Japan. It agrees with the definition and illustration 

 of G. asperulum KiJTZ. Kutzing does not give anj- localit\' for 

 his plant and nobody seems to have ever mentioned the spscies 

 to have found it since. In vSyll. .41g., IV, p. 159, it is enume- 

 rated among "spieces vix distingucndae aut ulterius inquiridae." 



In the Herbarium of the Botanical Museum of Berlin, there 

 are specimens similar to ours, collected by Mr. Y. Tanaka and 

 sent to Gkitnow. On the labels attached to them there arc 

 written in (jRUnow's handwriting: ''Gelidium corneum var. 

 ahnlich G. asperulum KiJTZ. Japan. lib. Gkunow. leg. Tanaka." 



I am inclined to think it advisable to record the present 

 species in the floristie list of marine algae of Japan though with
