In John Donnell Smith's distribution of Guatemalan plants 

 Masdevallia tubuliflora bears the number 8296. Up to the pre- 

 sent time I have been unable to identify my material with any 

 known species of the genus, although I have made careful com- 

 parisons with the specimens in the herbaria at the Royal Gar- 

 dens, Kew, and the British Museum of Natural History.
