CALANTHE MASUCA. 



161 



In Galanthe masuca and the hybrid C dominii the 

 structure is very different to what it is in most other 

 VandeaR. We here have two oval, pit-like stigmas 

 on each side of the rostellum (fig. 26). The viscid 

 disc is oval {^g. B), and has no pedicel, but eight 

 masses of pollen are attached to it by very short and

easily ruptured caudicles. These pollen-masses radiate 

 from the disc like the leaves of a fan. The rostellum 

 is broad, and its sides slope on each side towards the 

 lateral pit-like stigmas. When the disc is removed 

 the rostellum is seen (fig. C) to be deeply notched 

 in the middle. The labellum is united to the column 

 almost up to its summit, leaving a passage (n, A) to
