[Sketch of a grass and roots with labeled anatomy on right of page]

A-from p2-

All vegetable cells are of the same nature and all plants consist of cells-The differences we see among plants are accounted for by the different grouping or combination of these cells, their differing contents, and their different forms.

The progress of botany, strange as it may seem was materially aided by the imagination of the poet Goethe who conceived the idea of a typical plant after which all the various forms of vegetation were conceived to be moddeled [modeled].

The form and condition of plants are ever changing. The seed germinates & disappears-leaves are formed succussing and the lower ones die away while others are found above. Finally the whole strength of the stalk & leaves is exhausted in the production of seeds destined again to go through the same process the next year!

The suggestion of Wolff & Gothe that all the various parts of a plant, [the] may be reduced to two the axis or stem, and the leaf and their modifications appears to have been adopted and amplified by later investigations. It seems difficult to believe that the Calex, Corolla, and even stamens, pistils, & the coverings of the seed are only so many modified leaves. Yet this appears to be the case
