Question: What type of category does Origanum and Athyrium have in common?

full_context: Document 1: Ornithogalum: Ornithogalum is a genus of perennial plants mostly native to southern Europe and southern Africa belonging to the family Asparagaceae. Some species are native to other areas such as the Caucasus. Growing from a bulb, species have linear basal leaves and a slender stalk, up to 30 cm tall, bearing clusters of typically white star-shaped flowers, often striped with green. The common name of the genus, Star-of-Bethlehem, is based on its star-shaped flowers, after the Star of Bethlehem that appeared in the biblical account of the birth of Jesus. The number of species has varied considerably, depending on authority, from 50 to 300.
Document 2: Cyathea: Cyathea is a genus of tree ferns, the type genus of the fern order Cyatheales.
Document 3: Origanum: Origanum ( )is a genus of herbaceous perennials and subshrubs in the family Lamiaceae, native to Europe, North Africa, and much of temperate Asia, where they are found in open or mountainous habitats. A few species also naturalized in scattered locations in North America and other regions.
Document 4: Athyrium: Athyrium (lady-fern) is a genus of about 180 species of terrestrial ferns, with a cosmopolitan distribution. It is placed in the family Athyriaceae, in the order Polypodiales.
Document 5: Polystichum: Polystichum is a genus of about 260 species of ferns with a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 120 species in China alone; the region from Mexico to Brazil has nearly 100 additional species; Africa (17 species), North America (15 species), and Europe (5 species) have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions (a few species grow in alpine regions).
Document 6: Athyrium filix-femina: Athyrium filix-femina, the lady fern or common lady-fern, is a large, feathery species of fern native throughout most of the temperate Northern Hemisphere, where it is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration.
Document 7: Athyrium yokoscense: Athyrium yokoscense, commonly known as Asian common ladyfern in English and as "Hebino-negoza" in Japanese, is a species of fern in the family "Athyriaceae". These tough plants live primarily in and around mine sites and thrive in soils contaminated with high concentrations of heavy metals, such as zinc, cadmium, lead, and copper. "A. yokoscense" is indigenous to Japan, Korea, eastern Siberia and northeastern China and has been known for centuries to tolerate phytotoxic mining sites. The predominance and concentration of this fern species at a particular region was used to identify potential mining sites. The primary potential of "A. yokoscense" is in its phytoremediative ability to accumulate toxic metals from soils contaminated with heavy metals, so it may have some long-term commercial importance. No medicinal or culinary values of this fern species have been studied or confirmed.
Document 8: Satureja: Satureja is a genus of aromatic plants of the family Lamiaceae, related to rosemary and thyme. It is native to North Africa, southern and southeastern Europe, the Middle East, and Central Asia. A few New World species were formerly included in "Satureja", but they have all been moved to other genera. Several species are cultivated as culinary herbs called savory, and they have become established in the wild in a few places.
Document 9: Origanum dictamnus: Origanum dictamnus (dittany of Crete, Cretan dittany or hop marjoram), known in Greek as "δίκταμο" ("díktamo", cf. "dittany") or in Cretan dialect "έρωντας" ("erontas", "love"), is a tender perennial plant that grows 20–30 cm high. It is a healing, therapeutic and aromatic plant that only grows wild on the mountainsides and gorges of the Greek island of Crete, Greece. The dittany of Crete is widely used for food flavouring and medicinal purposes, in addition to it featuring as an ornamental plant in gardens. This small, lanate shrub is easily recognised by the distinctive soft, woolly covering of white-grey hair on its stems and round green leaves, giving it a velvety texture. Tiny rose-pink flowers surrounded by brighter purple-pink bracts add an exuberant splash of colour to the plant in summer and autumn. The dittany is classified as vulnerable on the IUCN Red List of Threatened Plant Species 1997.
Document 10: Polypodium: Polypodium is a genus of 75–100 species of true ferns, widely distributed throughout the world, with the highest species diversity in the tropics. The name is derived from Ancient Greek "poly" (πολύ) "many" + "podion" (πόδιον) "little foot", on account of the foot-like appearance of the rhizome and its branches. They are commonly called polypody or rockcap fern, but for many species unique vernacular names exist.
Document 11: Micromeria: Micromeria is a genus of flowering plants in the mint family, Lamiaceae, widespread across Europe, Asia, Africa, and North America, with a center of diversity in the Mediterranean region and the Canary Islands. It is sometimes placed within the genus "Satureja". The name is derived from the Greek words
Document 12: Ocimum: Ocimum is a genus of aromatic annual and perennial herbs and shrubs in the family Lamiaceae, native to the tropical and warm temperate regions of all 6 inhabited continents, with the greatest number of species in Africa. Its best known species are the cooking herb Cooking basil, "O. basilicum" and the medicinal herb Tulsi (holy basil), "O. tenuiflorum".
Document 13: Leptosporangiate fern: Leptosporangiate ferns are the largest group of living ferns, including some 11000 species worldwide. They constitute the subclass Polypodiidae, but are often considered to be the class Pteridopsida or Polypodiopsida, although other classifications assign them a different rank. The leptosporangiate ferns are one of the four major groups of ferns, with the other three being the Eusporangiate ferns comprising the marattioid ferns (Marattiidae, Marattiaceae), the horsetails (Equisetiidae, Equisetaceae), and whisk ferns and moonworts.
Document 14: Pot marjoram: Pot marjoram is a common name for a number of species of "Origanum" used as herbs, including:
Document 15: Origanum onites: Origanum onites, the Cretan oregano, Turkish oregano, pot marjoram or rίgani in Greek (Ελληνική ρίγανη), is a plant species in the genus "Origanum" found in Sicily, Greece and Turkey. It has similar flavors as oregano. Its essential oil can be distinguished from other species such as Greek oregano ("Origanum vulgare ssp. hirtum"). It has antimicrobial activities.
