The Dujardin coloring technique

The images shown are taken from a beautifully colored prepared slide from the archives of the Royal Antwerp Society for Micrography. The slide is already several decades old. It shows a cross-section of a twig of the plane tree. In spite of the age of the slide, the colors are still clear and fresh thanks to the use of the simple simultaneous Dujardin coloring method. During the coloring the colors were brought into balance with great skill, showing the various plant tissues. On the fluorescence image the plant various tissues are shown in a different manner.

Green curls

Cord moss or Funaria hygrometrica is one of the most common mosses in The Netherlands, especially in severely disturbed and nutrient-rich places such as vacant lots, semi-paved roads etc. A favorite habitat is burning places. A short time after the occurrence of a burn spot, Funaria hygrometrica is almost always present. The spread with spores via the air is extremely effective! In The Netherlands there are few large areas where there is so little disruption that there is no suitable place for Funaria hygrometrica, even if only temporarily.
