* The lip is described and figured by Swartz as trilobed, but in all the 

 Jamaican specimens examined by us, including Swartz's type, the lateral 

 lobes are not evident. Swartz describes his figure as the flower of 

 M. spieata or M. umbelliflora, and in his description of the latter omits 

 the parts of the flower as being very similar to M. spieata. The drawing 

 agrees best with M. umbelliflora, under which we have cited it. In his 

 Icon. ined. tt. 19 & 20, the flowers are represented as precisely similar, 

 and we can only suggest that a flower of M. umbelliflora has been drawn 

 for each plate.
