TRICHOSANTHES PALMATA.

1. Flowering branch of the male plant, natural size.

2. A flower split open to show the insertion of the stamens.

3. Stamens detached.

4-5. The same split open, showing; the long cells of the anthers, winding upwards and downwards on the back of the connectivum.

6. The staminal column cut transversely, showing the anthers one-celled.

TRICHOSANTHES PALMATA.

1. Flowering branch of the female plant.

2. A flower split open showing 4 sterile anthers. This number is not uniform.

3. Ovary, style and stigma.

4. Ovary cut vertically, through some oversight the more important transverse section is not given.

5. A mature fruit, natural site.

6. The same cut transversely, showing that the placenta at this period contract adhesions to the parietes, which is not the case at first.

7. A seed with its pulp.

8. The pulp removed.

9. The same cut transversely.

10. A cotyledon with its minute radicle.

11. The detached radicle and plumula. I fear this last figure is not quite correct.

OBS. — This plate was prepared long after the others which will account for the error in the numbering. The object of it is to illustrate my remarks on some of the sections of Dr. Arnott's Conspectus.

1. Female flower the corolla removed, showing the ovary, style, stigmas and disk.

2. Male flower corolla removed, showing the calyx and stamens, anthers like those of Trichosanthes.

3. Detached stamens.

4. Female disk, the style removed to show the sterile gland -like anthers.

5. Ovary cut transversely, showing the inverted carpels with the aid of colouring a little more distinctly than in nature.

6. The ovary cut vertically.

1. Female flower.

2. Male flower, corolla and calyx removed to show the stamens which correspond in form with the accompanying figures of section 7, but not with Cucurbita.

3. Style and stigmas.

4. Ovary cut vertically.

5. Cut transversely. The carpillary lines though apparently single, are actually double and do not cohere in the very early stages of the ovary.

6. A full grown fruit reduced in size.

7. The same cut transversely, showing the changes it undergoes in its progress towards maturity.

8. A seed.

9. The same slightly magnified.

10. (By mistake l6) a cotyledon showing the radicle at the base.

11 . A seed, testa removed showing the naked cotyledons.

1. Male flower and a detached petal, showing the stamens in situ.

2. Detached stamens.

3. Stamens separated showing the connective, not more lobed than in Coccinia.

4. Apex of the ovary, with calyx, styles and stigmas.

5. Ovary cut transversely.

6. A seed.

7. A cotyledon and radicle.

8. A seed cut transversely.

1. Male flower corolla removed, anthers undulating on the margin, but not lobed.

2. Female flower similarly dissected.

3. Ovary cut transversely.

4. A portion of it cut vertically.

5. A seed.

6. Cut transversely.

1. Male flower.

2. The same opened showing the anthers from within, not cohering, and abortive ovary.

3. Anthers different views.

4. Female flower.

5. The same, corolla removed.

6. A mature fruit.

7. The same cut transversely, 2-celled with 2 seed in each.

8. A seed somewhat smaller than nature.

9. The same magnified, rough on the surface.

10. Cut transversely.

11. Divided longitudinally.

12. Cotyledons, testa removed.

1. Male flower, split open.

2. Stamens detached, one of them separated and seen from within.

3. Female flower dissected, showing the styles and stigmas
