interglacial periods, exemplified by the Riss-Würm and Würm glaciations = maps, landscapes, plant fossils, photographs. The postglacial history of the flora is illustrated in the third part of the exhibition as an organic connection of the themes. It is hinted at already here. B. — 6. The floral and vegetation maps of Europe and Northern Asia = in smaller scales ; the floral maps of Hungary = in larger scale. 7—8. The floristic elements, relict and endemic plant species of Hungary, with special stress on the connections with steppe vegetation == pressed plants between glass sheets, distribution maps, photographs. 9. The reconstructed and recent flora of Hungary, that is, its division according to cultivations — a dioramatically spaced sketchy imitation in a bird's-eye view ; above it, on three sides, the course of development between the original and recent stages. C. — 10—13. In horizontal cases : coal and peat samples, stratigraphical profiles, the succession (secular) of plants, paintings, reconstructed vegetational pictures, photographs, drawings, diagramms. Main Theme II. A. — In 5 standing cases: 1. Development and growth: monocotyledons, dicotyledons, root-growth = plaster models ; wheat and bean seeds, cross section and structure ; paintings and drawings of germination stages, of development phases on a radical cell, etc. 2. Reproduction : instances of sexual: and asexual reproduction = a painting of floral parts ; photographs of pollination of enlarged pollen grains ; preparations, etc. 3. Plant nutrition : absorption from the air, photosynthesis, respiration, nutrition from the soil, diseases of deficiency in nourishment r the transportation and accumulation of nourishment in the body of plants, the plant and its surroundings in biological respects (effects of light and temperature) — plant preparations between glass sheets : sunflower grafted on artichoke ; tobacco and cotton preparations for the display of short and long daytime ; colored paintings (leaf parts, cells, color bodies for the illustration of photosynthesis), respiration, absorption from the soil, building and active elements ; the assimilation graph of the potato, etc. 4. The water economy of plants : subterranean root system, translocative equipment, evaporating system = preparations : roots, plaster models : rootlets, rootcaps, an enlargement of the stem ; wooden model for the illustration of the stoma ; a painting of the autumnal defoliation and leaf hairs ; a photograph of the model of translocative system ; a circular graph of the diurnal course of the movements of respiration apertures, etc. 5. The dispersal of plants : seeds dispersed by the media of wind, water, animals and internal forces = against a painted and natural background, and on glass sheets, enlarged paintings of seeds and the habit pictures of plants. 6. The life forms of plants : therophyte, geophyte, hemicryptophyte, chamaephyte, phanerophyte plants. Paintings of the most characteristic landscapes of the five life form types, with plant preparations between glass sheets beneath them, paintings and photographs. By these themes and materials, displayed in five standing cases, we introduce the visitor to the fundamental informations in botanies. In the followings, we expose chapter B) of Main Theme II, in 6 standing and 12 horizontal cases, in the subsequent treatment : the origin of wheat, our wheat forms, the agrotechnics of wheat, in sketches.
