The nearest ally of the magnificent Orchid here figured 

 is P. Victoria-Marias, Rolfe (t. 7573) under which species 

 I have given the reasons for adopting the unfamiliar 

 generic name of Paphio'pedilum. Both are natives of 

 Sumatra, in both the raceme is, as it were, perennial, con- 

 tinuing for a year or more to give off a succession of 

 flowers, of which one, two, or rarely three, are open at a 

 time. In this respect, and those of the mottled leaves, the 

 stout, dark purple scape, large boat-shaped herbaceous 

 bract, orbicular green upper sepal, twisted petals, and 

 open mouth of the lip, the two species agree ; but 

 P. Chamberlainiamim differs in the much broader, shorter 

 leaves, much more inflated lip, the almost orbicular
