Every case should be arranged according to a certain fundamental principle. Thus for instance, I had arranged the case of Parasite-Plants according to the basic principle of depth of penetration into the host. I have started with exmatrically root semi-parasites, e.g., Euphrasia officinalis or Alectoerolophus minor and concluded with imatrically shoot-parasites, with Pilostyles. In the case "Mangrove" I have shown that in the first place the root-system and the arrangements for propagation must be suited to the saturated soil, poor in oxygen. Objects which, due to their height, cannot be placed in cases are best put on special stands alongside of them.
How shall the botanical museum be divided? In answering this question I would like to confine myself to conditions in Munich-Nymphenburg, my former sphere of action. This arrangement was very practical, I will demonstrate it in the following lines:
I. Systematic Division.
Here representatives from all plant families are shown as far as they are visible with the naked eye. The start is made with algae, fungi, liver worts (hepaticae), mosses (mucoi), passes over to vascular cryptogames (pteridophytes), to gymnosperms and concludes with the dicots and monocots. Flowers, leaves, branches and fruits and seeds are to be seen here.
II. Morphological Division.
1. Shoots
a) structure of shoot (nodes and internodes, long- and short branches, symmetry, polarity etc., adventitious shoots)
b) metamorphosis of shoot (cladodes, phylloclades, stem-succulents, stolons, rhizomes, aerial and subterranean tubers, bulbs, shoot-thorns, shoot-tendrils)
c) wood, lianes and used woods
2. Roots
a) transition from shoot to root (horse-radish)
b) rootlike prehensile organs, holdfast organs of Laminaria-species.
c) root systems
d) metamorphosis of root (anchoring roots, prop roots, respiratory roots,
