Botrychium lunaria

Posted by Johan Dierckx (Wijnegem, Belgium) on 10 September 2012 in Plant & Nature and Portfolio.

Botrychium lunaria (NL: Gelobde maanvaren / EN: Common moonwort / DE: Echte Mondraute / FR: Botryche lunaire) is a species of fern. It is the most widely distributed Botrycium, growing throughout the Northern Hemisphere across Eurasia and from Alaska to Greenland, as well as parts of the Southern Hemisphere including South America and Australia. This is a small plant growing from an underground caudex and sending one fleshy, dark green leaf above the surface of the ground. The leaf is 6 to 10 centimeters tall and is divided into a sterile and a fertile part. The sterile part of the leaf has 4 to 9 pairs of fan-shaped leaflets. The fertile part of the leaf - see image - is very different in shape, with rounded, grapelike clusters of sporangia by which it reproduces.
