trifid, and always smooth from its insertion. The small
gland observed in the sinus at the base of the lip of O.fuci-
fera cannot be mistaken for that of O. arachnites, with which
the former plant has few characters in common, flowering
earlier, and presenting strap-shaped, minutely downy, and
jagged petals. The column of O. arachnites has, in the majority
of instances, a straight beak, and the space below the
stigma is stained of a blackish-green.—G. E. S m i t h , M.A.
