trioutpidota Elolfe. Flowers placed beside those of these three species at Kew, by 

 myself, were seen to be very similar; though the lip of E. gigantic does not 

 agree at all well with Hooker's figure for E. iridifolia (Ic. PI. t. 2067). nor 

 with Ridley's published description of E. bidens (Journ. Linn. Soc. Hot. 32: 289). 

 Mr. Kolfe's E. triouspidata is a much weaker plant than the others. E. gigantea 

 is at times extremely robust. According to the Kew and our own specimens, 

 which indeed are typical, the four species form a very close group within this 

 section.

A second Philippine species agrees well with the representations and descrip- 

 tions of E. major Ridley (E. Kingii Hook. f. Ic. PI. t. 9069), although im- 

 material has not been compared directly with the type.
