In the photos of the botanical prepared slide shown here, we see a part of the cross-section of a twig of Genista spec. The slide was made in 1964 and is in very good condition still. The coloring was done with the dyes acridine red, chrysoidine, and astra blue. The mounting medium is Caedax. Caedax is a synthetic substitute for Canada Balsam in microscopic techniques.
Genista or broom is a genus of shrubby plants known for their yellow flowers. Genista is originally from Southern Europe, Southwest Asia and North Africa and is well adapted to a Mediterranean climate with its hot dry summers, lean rocky ground and cool, wet winters.
