The following localities of this plant are added to those which I gave in 

 the former publications. 



HAB. Urai, Karapin, Kuraru, Bongari, 

 Buisan. 



The species is widely distributed in For- 

 mosa, northwards from Kelung as south as 

 Kuraru and South Cape ; but does not extend 

 to any higher elevation than that of 3000 ft. 



Pothos Warburgii ENGL. (in Bot. Jahrb. 

 XXV. p. 2) is very likely to be the same spe- 

 cies as Pothos Seemannii. Judging from the 

 description, I think, the former is a mere form 

 of the latter with a smaller spadix. So far, 

 P. Seemanni is the only species of the genus, 

 that we have seen in Formosa.
