1510. There cannot, however, be any plant which could simply possess the higher without the lower organs. Higher organized plants are not such therefore, by virtue of their having some one organ more perfectly developed, or separated into several parts; but through this, that they actually possess several different organs. The higher grade of organization depends accordingly not upon the perfection of the _Singular_, but the _number_ of the _Different_. The Perfected consists in the _multiplicity_ combined to constitute _unity_, but by no means in the simply homogeneous multitude of the _parts_. Numerous stamina may render a _corolla_ higher, but not on that account the whole plant; many digits may make a hand nobler, but not on that account, the animal. But with many digits also that hand is nobler, in which the digits are dissimilar. _First Province._ HISTOPHYTA--ACOTYLEDONES. _Devoid of, or without true spiral-vessels, leaves, corollæ, and pistil._ The vegetable kingdom ascends, in accordance with the five main positions of the organs, by five stages; these are again separable into larger groups, which may be called _asexual_ and _sexual_ plants. 1511. The tissues are a something internal, being, as it were, the viscera of plants or their parenchyma, which does not meet the light, and can therefore have no light-organs, which are developed only out of the foliage or leaves. The anatomical systems and organs are tissues that have become external, have attained to air and light, and are hence developed into air-and light-organs. Now, the light-organs are sexual organs. The Tissue-plants can therefore have no sexual organs; and plants divide accordingly into asexual and sexual plants. The asexual are female plants, and are consequently the first or lowest. Thus there can be thus no sexual or male plants, without the female being found that belong to them. 1512. Male or androgynous plants are only possible, if spiral vessels or tracheæ be present. They first, however, originate when the tracheæ become external, or form a circle in the stalk, i. e. are accessible by light; as in the Mono-and Dicotyledones. 1513. The asexual plants are not cryptogamic, but agamic. They do not perform self-impregnation clandestinely, but not at all; for they do not attain light-difference, and consequently not male organs. Analogues of stamina may make their appearance in the mosses, but they invariably fail to attain the development of pollen. What have been called male parts in other cryptogamia, do not merit consideration. Such projections or prefigurations are besides to be found everywhere. 1514. The asexual plants are simply formations of the tissues, of the galvanic vesicle, and are thus of a female nature. They are nothing more than a great utricle full of small vesicles, which by desiccation subdivide into _germinal dust_ or sporules, each granule whereof attracts other mucous vesicles out of the moisture, in order to form again a large utricle.
