��EXPLANATION OF THE PLATES. RAFFLESIA ARNOLDI.

Tab. 21 (XXII).

Y'lp;. 1. A female flower-bud, with the roots of the Filis (or C'/wv/i-) vertically divided, which shows the numerous irregular cavities of the ovarium chiefly, if not entirely, above the insertion of bractcK and calyx, and the vascular lines continued from the walls of the cavities through the upper solid part of the column into the axes of the style-like processes : — natural size.

Fig. 2. A female flower-bud in the same stage of development, the bracteaj and calyx entirely removed, to show its outward resemblance to the male flower-bud (figured in Linn. Trans, vol. xiii, Tab. XXI) {Jfi/e, /. 19i :— natural size.

��Tab. 22 (XXill ...

Fig. 1. A small segment of the column, of which part of the elevated un- divided limb is removed, to show the narrow furrows of the sides of the column corresponding in number with the rudiments of antherie, seen in

Fig. 2, which is the portion of the limb removed from fig. 1 : — natural size. -237

Fig. 3. The upper half of one of the styles of the disc, with its terminating hairs: — magnified 10 diameters.

Fig. 4. A portion of fig. 3, somewhat more highly magnified {20 diameters), vertically divided.

Figs. 5, 6, and 7. Some of the hairs still more highly magnified, which, according to Mr. Bauer, have a secreting surface seen in fig. 7, and which in figs. 5 and G is covered with the secretion, consisting of spherical particles enveloped in mucus at fig. S: — magnified 100 diameters (but see observations respecting them in page 225). (J/ifi-, ]). -^LOo.)

Figs. 9 and 10. Longitudinal and transverse sections of a style : — magnified 50 diameters.

Fig. 11. A transverse section of half the ovarium, to show the numerous irregularly ramified cavities, and the arrangement of vascular cords belonging to the bractcrc and calyx : — natural size.

Fig. 12. A small portion of the ovarium, with the ovula covering the surface of the cavities, and the vascular lines passing through the axes of the parietes : — magnified 20 diameters.

Figs. 13 — 18. Ovula in various stages (the earliest observed are not repre* sented) :— magnified 100 diameters.
