b. The second stage is _that of the shaft_ or main axis, where these three have separated concentrically into cortex or _bark_, _liber_, and _wood_, constituting the anatomical _systems_ or _sheaths_. c. The third stage is that of the _caudex_ proper or the trunk, in which the three tissues have separated in the direction of the longitudinal axis into _root_, _stalk_ or stem, and _leaves_, these making up the _organs_ proper or _members_. The inflorescence divides into two stages, into _flower_ and _fruit_. d. The fourth stage or that of the _flower_ repeats root, stalk and leaves, in _seeds_, _pistil_ and in the _corolla_. e. The fifth stage or that of the _fruit_ is a further repetition of these three parts of the flower in the nut, plum and berry, unto which, as synthesis, comes the apple. A. _Vegetable-trunk._ 1046. The vegetable-trunk is the development of the three fundamental processes up to their complete separation or substantial representation. It divides itself into the tissues or the pith (parenchyma), into the shaft and into the trunk. 1047. The plant is a galvanic water-vesicle, and as such earth, water and air. Upon this vesicle it is, however, the earth-element that chiefly acts. While the earth seeks to encroach upon the vesicle, the magnetic process becomes active therein, and it enters into opposition with the air. The vesicle becomes now determined by two elements, by the earth and by the air; it stands itself in the category of the water. 1048. The plant may be characterized as organic water which is polarized upon two sides, towards the earth and the air. The vegetable vesicle must therefore maintain two poles. While it would represent in itself the magnetic pole, it endeavours to identify itself, to obey gravity and merge into the darkness towards the mediate point of the earth; but that it may remain a galvanic pole, it becomes excited by the air, strives to become a Different and to attain the light. 1049. The vegetable vesicle receives two opposed extremities, an identical earth-and a dyadic air-extremity; and thus the plant must be regarded as the organism, which manifests a constant endeavour, upon the one side to become earth, on the other air, upon the one side identical metal, on the other duplex air.
