as the figure given is sufficiently characteristic of the species,
and the characters derived from the scales depend upon their
general form and direction relatively to the corolla, not
upon their minute subdivisions ; these vary, but the others
are permanent.
In the figure of G. europcea at t. 378, and also in that
given by Hooker in El. Lond. N. S. t. 67, the scales are
omitted, although they are always present in that gpecies;
and indeed it is probable that they exist in every species of
the genius. In 0. europcea they form an internal membranous
transparent whorl, closely adpressed to the tube of the
corolla, each being connected with its neighbour below, and
terminating above in two long acute transparent points.
These parts are very imperfectly represented in 0. Epithy-
mum, t. 55. of this work.
In the above description the heads of flowers are said to
be pedunculated, and our present plant is distinguished
from G. europcea by that character amongst others ; they
appear to me to be equally sessile, or rather very slightly
stalked, in both plants.—0. C. B.
