. Elementary botany : theoretical and practical. A text-book designed primarily for students of science classes connected with the science and art department of the committee of council on education . Botany. Corolla 107 often highly coloured and possesses odour. If there be only one coat present, as in the Anemone and Marsh Marigold, whatever its appearance, it is spoken of as calyx. The corolla is either gamopetalous or polypetalous— regular or irregular. If the petals are attached with the calyx beneath the ovary (fig. 166, h), the corolla is said to be hypogynous; if the ovary be superior, but the petals, instead of being inserted under it, are attached upon the calyx, forming a ring round the ovary, the corolla is perigynous (fig. 166, p). When the ovary is inferior and the corolla springs from the top of it with the calyx (fig. 166, e), it is epigynous. The corolla never remains to form a part of the fruit as the calyx does Fig. 180,—Unguiculate petal of DianthuSf with toothed lamina. Fig. 181.—Bifid unguicu- late petal of Lychnis, with ligule. Fig. 182. — Tubular co- rolla from the disc of the capitulum of Cen- taiirea Cyanus Terms are also employed to describe the shape of the eorolla, and of the individual petals. When the petals are broad above and form a narrow limb below, as in the Pink (fig. 180) and Lychnis (fig. 181), they are said to be unguiculate or clawed. When each petal is notched at its free edge, as in the Lychnis (fig. 181), it is described as bifid. If there are several notches it is toothed (fig. 180), or, if very much divided, fimbriated, as in Dianthus plumarius. Again, the corolla may be tubular, as in the Bluebottle and o;her composite plants (fig. 182); eampanulate or bell-shaped,.
