Fj'fj. 1. Transverse section of a part of the tube of the pcrianthium, to show the three-lobed coluniua slaininea: — moderately magnified.
Fif^. 2. The inner surface of one of the tliree lobes of the column or antheral annul us.
Fig. 8, Outer surface of the same: — both magnified in the same degree with
Fifj. i. Vertical section of a portion of one of the lobes of the columna slaminea, to show the thickness and texture of the common connective.
Fig. 5. Transverse section of the same, which shows the original bilocularity of each anthera: — both more highly magnified.
Fig. G. Grains of pollen, still more highly magnified.
Fig. 7. Transverse section of the flower, to show the form and surface of [2:vj the stigma (of which the three primary divisions are opposite to the lobes of the columna staminea): — magnified in the same degree with fig. 1.
Fig. 8. A portion of the stigma, which shows its composition.
Fig. 9. A transverse section about the middle of the same: — both magnified somewhat more than figs, 2 and ."5. ^
Fig, 10. A vertical section of the stigma, showing that the divisions of its surface extend quite through to the cavity of the ovarium, separating it into an equal number of lamellae, from the inner terminations of which the placentae are pendulous: — more higlily magnified than the preceding figures.
Fig, 11. A small portion of the same, still more highly magnified.
Fig. 12. A transverse section, more highly magnified than fig. 11, with its densely crowded ovula arising from every part of its surface.
Fig, 13. Three ovula more highly magnified than fig, ]2, to show the pedicellus or attenuated base and depressed or perforated apex.
��Tab, 28 (XXIX).
A ripe fruit (fig. 1), with the stock (the root of the supposed Eup/iorbia, fig. 3) and the decumbent angular branched stems of the parasite, from the thickened trunk of which the ripe fruit originates at fig, 2, and from a branch of which a very young flower-bud proceeds:— natural size.
��Tab. 29 (XXX),
Fig, 1. The same ripe fruit vertically divided, with the prostrate thickened stem of the parasite and the root of the supposed Euphorbia, whose woody fibres and vessels appear to penetrate deeply into the substance of the thickened stem: — natural size.
Fig, 2, A portion of the fruit transversely divided.
Fig. 3. A transverse section of one of the placentrc, with the ripe seeds: — slightly magnified.
Fig. 4. Two seeds, more highly magnified than fig. 3.
Fig. 5. A seed, magnified in the same degree as fig. 1, and vertically divided, which exhibits the albumen more distinctly radiating than I have ever found it.
Fig. C. A seed deprived of its outer coat.
Fig. 7- The same transversely divided, which, as well as fig. .'>, shows the central globular embryo.
