The Mt. Mariveles specimen is in floral detail a counterpart of 

 those from Mt. Apo, but in habit the two sets are quite dissimilar. 

 This dissimilarity is most likely due to unnatural growing condi- 

 tions, as the Mt. Mariveles specimen has been grown in a green- 

 house. The leaves are broader and shorter than those of the type, 

 with short petioles, and are presumably more coriaceous ; the pseu- 

 dobulbs bear 2-4 leaves, which attain a maximum length of 2 

 dm. and a maximum width of 7 cm. The labellum of E. cylin- 

 drostachya appears to be retuse in some specimens.
