Grozdovnik, or Botrichium[1] (lat. Botrýchium), is a genus of perennial herbaceous terrestrial[2] ferns of the Uzhovnikov family.

Root system
Clusters are small herbaceous perennials with a more or less straight, shortened underground stem (1-4 cm long), with thick, non-branched, light-colored roots.
Stem
The above-ground part of the plant begins with a fleshy vertical axis (“stem”), above a third of the total height of the plant, it is divided into two: into a flat, more or less fleshy bright or light green leaf, slightly deviated from the axis, and into a direct continuation of it, dismembered at the top like a panicle (when young, cluster-shaped, hence the name of the genus), bearing numerous spherical sporangia on its branches.
Sheet
The sterile part of the leaf is pinnate, pinnately dissected or complex pinnately dissected, rarely (in some of the smallest forms) entire[5]. The spore-bearing part of the plate is also dissected into lobes.
Leaves develop very slowly. Each year, only one, rarely two, leaves are formed on the rhizome. By the number of leaf scars on the rhizome, one can roughly judge the age of the plant. Calculations show that some plants of Botrychium multifidum, common in Russia, especially in pine forests, are the same age as many hundred-year-old pines that live in the neighborhood.
In powerful specimens of some species of rosemary, snail-shaped leaf primordia and the presence of special vaginal stipule-like formations can be found in the bud. Like rhizomes, they sometimes show signs of dichotomous branching.
Fertile part
The fruiting part has the appearance of feathery clusters. Sporangia are free, arranged in two rows in complex spikelets or panicles, protruding outward in the form of small spherical bodies; they open with a transverse crack (like that of the grasshopper).
The most primitive type of arrangement of sporangia among the grasshoppers is observed. Its sporangia are located both on the sides of the branches of the spore-bearing part and on the tops of individual branches .
Gametophytes are dorsiventral, ovoid, flattened-tuberous or disc-shaped, from 1 to 20 mm long.
Gametangia are numerous and scattered over the surface of the gametophyte; antheridia occupy the top of a special ridge, and archegonia are scattered along the slopes of the ridge or on the ventral side of the gametophyte. Antheridia are large, submerged or slightly protruding above the surface of the gametophyte; archegonia are quite deeply buried[5].
The spores are pale, spherical-tetrahedral, with three stripes . Spores germinate extremely rarely (and extremely slowly) and develop underground, tuberous, colorless, bisexual growths.
Distribution and ecology
A few species of the genus are sporadically distributed in fairly humid areas of the tropical and temperate zones. In the northern forest zone, some of them extend to its northern limit. Regardless of the degree of commonness, the species of rosemary never play a significant role in the formation of plant groups.
Clusters are confined not only to shaded forests, but also grow in meadows, swamps, and tundra communities[8], growing on loose and moist soil and in open areas.
Many wildflowers are often found in places where the vegetation cover was once disturbed (overgrown roadsides of forest roads, excavations, etc.). Different species grow in soils of varying acidity.
