tricuspidata Rolfe. Flowers placed beside those of these three species at Kew, by 
myself, were seen to be very similar; though the lip of E. gigantea does not 
agree at all well with Hooker’s figure for E. iridifolia (Ic. PI. t. 2061), nor 
with Ridley’s published description of E. bidens (Journ. Linn. Soc. Bot. 32: 289). 
Mr. Rolfe’s E. tricuspidata 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. Eingii Hook. f. Ic. PI. t. 2066), although my 
material has not been compared directly with the type.
