Scientific German Educational Chart by Jung-Koch-Quentell, it illustrates the Dandelion plant.

Originally illustrated in the 1950s and 60s, this reproduction chart by the same company was printed in the mid 1970s in six to ten colors by hand to ensure vibrant color and intricate detail.

This chart is mounted on canvas and fitted with stable wooden rods. It measures 44.5 inches tall by 32.25 inches wide (85 cm x 120 cm).

The chart comes with a nylon cord that passes through the top wooden rod for easy hanging.

The illustration includes:

1. A complete plant: Eight inflorescences and fructifications on long, leafless stalks, showing the various stages of development. One head as new bud, others with the yellow, tongue-shaped individual flowers. The last stage is represented by an almost empty fructification; the dimples, in which the achenes were seated, are visible.
2. The synoptic picture shows tap root with adevntitious roots and the short rhizome just underneath the rosette.
3. Longitudinal section of composite flower. The marginal- or ray-flowers are female; the mature bifurcated stigma is rolled back. Inside the young, not yet open central- or disc-flowers and between them some floral leaves in pre-male phase with pollen above staminate tube.
4. Transverse cut through peduncle with peripheral ring of vascular bundels.
5. Tongue-shaped single flower with the five petals, forming the tongue. The bifurcated stigma rises above the tube of stamens. The calyx is formed by a corolla of hairs, the filament being still very short.
6. Enlarged portion of lingual flower. The tube of stamens is cut open; the single filaments of the stamens and the pistil with the forked stigma are to be seen.
6. Two single fruits (achenes)
7. Filament of the tufted fruit has growon much longer
8. Rhizome and pieces of roots produce new plants
9. Transverse section of root. Inside the central cylinder or stele, it is surrounded by a spongy area, the cortex, with the regions of specialized cells.
10. Section of a vascular ring of the cortex, showing sieve-tubes with companion cells, conductors of the milky sap, and sieve-parenchyma
