lip and pollen apparatus of Mormodes I must refer to Mr.<br />

Darwin's work on " The Fertilization of Orchids " (p. 208),<br />

where it is shown how perfectly all the parts are contrived<br />

and arranged to cause the pollen to alight on an insect<br />

visiting the flower, and to be thence carried to other flowers<br />

in a position to secure their fertilization.<br />

province of Ocaña, at elevations of 4000 to 5000 feet, and<br />
