Collins^ states a doubt if P. femlacea Suhr might be the 

 same as P. havanensis var. Binneyi J. Ag. J. Agardh 2 ' has also 

 remarked a close affinity between them. 



During the study of the original specimens in the Agardhian 

 Herbarium it happened very frequently to think in my mind 

 that if the eminent algologist has not been inclined to separate 

 one and the same plant into different species on account of its 

 greatly distant localities — intermediate localities being unknown 

 to him. The present species is one of the examples. 



Locality. Yenoshima, Sagami Prov. ( ! ) ; Shimoda, Idzu 

 Prov.(!); Nakiri, Shima Prov. (Herb. Imper. Museum, No. 135) 

 (!); Aki Prov. (Komatsuzaki, No. 15). 



Distribution. Atlantic coast of Mexico; Guadeloup Island; 

 Australia; Noukahiva Island; Sandwich Islands; Batan Islands 

 (T. Aoki, No. 9). 



Lophocladia Lallemandii Scum.

(For synonymcs and other references, see: De Toni, I.e.). 



The three species of Lophocladia resemble one another so 

 that to distinguish them by mere descriptions is a difficult 

 matter. The difference in the initiating modes of the lateral 

 branches between L. trichoclados and L. Harveyi, pointed out 

 by Sciimitz is the essential hit mark. Falkenuerg" observes 

 in L. Lallemandii that ,,Die untersten Segmente des Kurztricbes 

 (ramelli) blciben stets ohne seitlichc Glieder, und ebenso blcibt 

 der obcre Abschnitt unvcrzweigt" while in L. trichoclados ,,Ihr 

 Illiterates und meist auch das folgende Segment ist unvcrzweigt." 

 This observation, however, does not agree with the illustrations 

 given by Ki'rzixo in Tab. Pbyc, XIV, Taf. 71 for L. Lallcmandi 

 and L. Harveyi, and in Tab. I 'live, Taf. L'2, fig. a-b, ami lab. 

 l'hyc, XIII, Taf. 75, fig. a-e for L. trichoclados.
