Pseudixus^' is a genus which was published quite iccently 

 by myself as a new genus of the Loranthaceae founded on a 

 ver}' common species formerly called Viscum japonicum Thunb. 

 Soon after publication, my attention was called to the genus 

 Bifaria^^ of Van Tiegiiem, by Mr. E. D. Merrill of Manila 

 and Mr. T. Sprague of Kew. Pseudixus is apparently closely 

 related to Bifaria and also to Kortbalsella'^ in having trimerous 

 flowers and in the shape of the internodes. 



It is certainly a remarkable fact that Pseudixus japonicus 

 {= Viscam japonicum) has stamens which are arranged alter- 

 nately to the perianth-lobes and two-celled anthers which are 

 perfectly united with one another at the center of the flower, 

 but quite free from the perianth-lobes, and which burst, when 

 mature, in the connate suture, or open with a single cental 

 pore/' In respect of the relative position of stamens to the 

 lobes, the genus, Pseudixus, stands without a parallel. No 

 flower with this staminal arrangement has ever been recorded 

 in any other plant of the family.
