This plant is closely allied to B. occultum, Thouars, and 

 B. variegatum, Thouars, natives of Mauritius and Bourbon, which 

 have not yet been recorded from Madagascar. It differs from 

 those species in the fewer and more distant bracts, and the larger, 

 apparently purple flowers, the broader lip, and acute long teeth 

 of column. The leaves are stiff* and hard, 6 inches in length by 

 | inch in the broadest part. The scape is about the same length, 

 bears a nodding raceme of about 9 flowers.

The petals and dorsal sepal in the East-Asiatic form are yellow 

 with brown spots; the lateral sepals cinnamon or tawny, the 

 inner side dotted with red-brown ; but in Thouars's figure the 

 dorsal sepal and petals are coloured greeu, the column and lip 

 pink, the lateral sepals white. Perhaps there is some mistake 

 in this colouring, for in the synopsis, he says under petals, 

 "tr. long, rouge obscur." He also represents the fruit as pen- 

 dulous and stouter than in the Polynesian plant, in which it is 

 generally at least erect when ripe. The leaf in the Mauritian 

 plants seems io be narrower than that of the Polynesian variety. 

 The remaining species of the genus are East-Indian, with out- 

 lying species in China and Australia.
