coherent forming a rounded cup. In the drawing of the 
flower the lateral sepals were forced apart to show their 
outline and to reveal the petals, labellum and column. 
The flowers vary markedly in size, the sepals of the type 
being about 8 mm. long and in some of the more luxu- 
riant forms being twice that length. In S&. pardipes the 
flowers are so distinctive that there is no likelihood of 
confusing it with any other known Stelis. The column 
has stigmatiferous lateral lobes.
