The multi-part diamond fern is a deciduous, perennial herbaceous plant that reaches heights of 5 to 15 centimeters. It produces two to rarely four leaves a year, only one of which has a fertile , hairy section, the sterile sections are stalked up to 6 centimeters long, thick, fleshy, yellow-green, triangular and double-pinnate, their tips are rounded, entire or notched. The fertile section is long-stalked and double to triple pinnate. Some of the leaves overwinter.

Spore ripening is from July to September.

The number of chromosomes is 2n = 90.

ecology

The multi-part diamond fern is a geophyte .

Occurrence

The multi-part diamond fern is distributed from the temperate to the boreal areas in the northern hemisphere in Eurasia and North America . In Scandinavia it is only found sporadically up to 70 ° north latitude, in Atlantic Europe it is largely absent, in the east it is significantly rarer; to the south there are finds as far as the Alps (here up to altitudes of about 1300 meters) and as far as the Carpathian Mountains , an isolated occurrence is also reported in the Apennines .

The multi-part diamond fern populates moderately fresh to fresh silicate grasslands , roadsides and open forests, it avoids lime . It likes to be found together with bristle grass ( Nardus stricta ) and blue whistle grass ( Molinia caerulea ), i.e. in societies of the order Nardetalia.
