The leaves are about 8 inches long by 5 lines in diameter. The 

 raceme in the type-specimen is 6 inches long, the flowers rather 

 distant. The sepals are 7 lines long, the lip including the cusp 

 is of the same length, the latter is \ inch. In Thouars's figure 

 the flowers are given as entirely white ; but in plants flowered 

 by Mr. Christy at Sydenham, March 1885, the sepals and petals 

 were light green and the lip white. 



Crtptopus. 



This monotypic genus is confined to the Mascarene Islands. 

 The only evidence I have of its being a Madagascar plant is a 

 flowerless specimen collected by Lyall, which necessarily is rather 

 doubtful. It seems, however, common in Mauritius, and will 

 probably be found in Madagascar when the eastern coast is more 

 fully explored.
