flower, with stamens opposite perianth-lobes ; the latter has 

 a double dimerous flower, with stamens originally alternate to 

 perianth-lobes, but seemingly opposite the same lobes. As to 

 vegetave organs, female flowers and fruit, it is nearly identical 

 with Viscum. It would be the most natural way to place 

 this new genus in the subfamily, Viscoidea, and quite close to 

 Viscum. 



The geographical distribution of Pseudixus, it is at present 

 difficult to state exactly. But, assuming that all plants 

 recorded as Viscum japonicum Thunb. from different parts of 

 our hemisphere are quite identical (I am very sceptical on this 

 point) with our false mistletoe, the new genus is distributed 

 widely from the Himalayas, India, Malaya, Mauritius, Australia 

 and Polynesia through China, Formosa, the Loo-choo and 

 Bonin islands to Japan where it spreads as far north as Nikko. x) 



The technical description of this new genus is not here 

 annexed, as I think that this explanation presents the case 

 more clearly than could be done in a simple Latin diagnosis. 

 The latter, however, will be given in my Icones Plantarum 

 Formosa.narum Volume V. now in preparation. 



In conclusion, it is a pleasure to me to acknowledge my 

 indebtedness to Prof. S. Kusano and Dr. Y. Miyaji for their 

 preparations of this interesting flower. 



1) I am informed by Dr. S. Komatsu that the plant exists, though not very 

 frequently, in Nikko.
