at p. 135, and figs. 2d and 2g, Plate 184.)
Two characters may arise from the undulations in the Eudesmieae—
(a) The width of the staminal ring may be greater at the crests or tops of each undulation,
becoming narrowest in each trough. (See fig. 2d, Plate 184.)
(b) The lengths of the filaments vary, the longest emerging from the crests of each undulation.

E. tetrodonta.—It is expedient to again refer to this species in connection with
figs. 2 and 3a, Plate 185, and top of page 136, Part XLV. Calyx distinct, as
depicted, the lobes prominent, thick, obtuse, free from the operculum at the apex;
operculum thin. Staminal ring cylindrical, raised above the undulate calyx lobes.
Filaments numerous, slender, attached to the top of the staminal ring in an almost
uniform manner, and not in four clearly distinct bundles. That the four bundles are
not clearly marked is shown in fig. 3a. The undulate calyx-lobes in this species are
not to be confused with the undulate staminal ring common in the Eudesmieae.

DISC OF THE FLOWER.
Historical.
Bentham, 1866.
Mueller, 1879-84.
Following are the species in which Bentham refers to the disc, so far as the
stamens are concerned, but I cannot trace where he gives a definition of the disc:—
E. macrocarpa. “Their insertion (stamens) raised to about 2 lines above the edge
of the calyx by the thick edge of the disc, which is also often slightly raised within
the stamens in a ring round the ovary.” (B.Fl., iii, 224.)
E. globulus. “Stamens . . . raised above the calyx by the thick edge of the
disc.” (Ib., 225.
E. pyriformis. “Disc very broad, forming within the stamens a thick prominent
ring round the depressed top of the ovary.” (Ib., 226.)
E. conoidea (erythronema). “Stamens . . . raised by the thick disc 1/2 to 1 line
above the border of the calyx.” (Ib., 227.)
E. robusta. “Stamens . . . somewhat raised above the calyx-border by the annular
margin of the disc.” (Ib., 228.)
E. Preissiana. “Disc broad and concave, the ovary with as many protuberances in
the centre as valves.” (Ib., 232.)
E. annulata. “ . . . the margin of the disc that bears them (stamens) forming a
