Its general nature and function [65]
Consists essentially of Corolla and Treasury [78]
Has in perfect form the following parts:—
I. The Torus.—Not yet enough described in the text. It is the expansion of the extremity of the flower-stalk, in preparation for the support of the expanding flower [66], [224]
II. The Involucrum.—Any kind of wrapping or propping condition of leafage at the base of a flower may properly come under this head; but the manner of prop or protection differs in different kinds, and I will not at present give generic names to these peculiar forms.
III. The Calyx (The Hiding-place).—The outer whorl of leaves, under the protection of which the real flower is brought to maturity. Its separate leaves are called Sepals [80]
IV. The Corolla (The Cup).—The inner whorl of leaves, forming the flower itself. Its separate leaves are called Petals [71]
V. The Treasury.—The part of the flower that contains its seeds.
VI. The Pillar.—The part of the flower above its treasury, by which the power of the pollen is carried down to the seeds [78]
