Botrychium is a genus of ferns, seedless vascular plants in the family Ophioglossaceae. Botrychium species are known as moonworts. They are small, with fleshy roots, and reproduce by spores shed into the air. One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases. Some species only occasionally emerge above ground and gain most of their nourishment from an association with mycorrhizal fungi.
Sceptridium is a genus of seedless vascular plants in the family Ophioglossaceae, closely allied to the genus Botrychium. It is also closely related to the genus Botrypus. Sceptridium species are commonly called the grape-ferns.

Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera, divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level.
Microsorum is a genus of ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). The species are tropical. Like most ferns, they grow from rhizomes, rather than roots. The genus name is often misspelled "Microsorium" or "Microsoreum". It includes some species that are lithophytic rheophytes.
Polystichum is a genus of ferns in the family Dryopteridaceae, subfamily Dryopteridoideae, according to the Pteridophyte Phylogeny Group classification of 2016. The genus has about 500 species and has a cosmopolitan distribution. The highest diversity is in eastern Asia, with about 208 species in China alone; the region from Mexico to Brazil has at least 100 additional species; Africa, North America, and Europe have much lower diversity. Polystichum species are terrestrial or rock-dwelling ferns of warm-temperate and montane-tropical regions. They are often found in disturbed habitats such as road cuts, talus slopes, and stream banks.
Physocarpus, commonly called ninebark, is a genus of flowering plants in the family Rosaceae, native to North America and northeastern Asia.
Allium textile is a common species of wild onion found in the central part of North America.
Hecistopteris is a fern genus in the Vittarioideae subfamily of the Pteridaceae.
Scapania is a genus of liverworts in the family Scapaniaceae. It contains the following species :
Cyrtomium falcatum is a species of fern, commonly known as house holly-fern and Japanese holly fern, in the wood fern family Dryopteridaceae. It is native to eastern Asia.
Dracocephalum rupestre is a plant species in the genus Dracocephalum, endemic to China. The specific epithet, "rupestre", is derived from Latin, and pertains to the plant growing among rocks.
Campyloneurum angustifolium is a fern species in the family Polypodiaceae, commonly known as narrow strapfern or narrow-leaf strap fern.
Flora of China is a scientific publication aimed at describing the plants native to China.
Poa secunda is a widespread species of perennial bunchgrass native to North and South America. It is highly resistant to drought conditions, and provides excellent fodder; and has also been used in controlling soil erosion, and as revegetator, often after forest fires. Cultivars include 'Canbar', 'Service', 'Sherman', and 'Supernova'. Historically, indigenous Americans, such as the Gosiute of Utah, have used P. secunda for food. It was originally described botanically in 1830 by Jan Svatopluk Presl, from a holotype collected from Chile by Thaddäus Haenke in 1790.
Edward (Ted) George Hudson Oliver, is a South African Botanist and author. He is an expert in heathers. He has discovered and named several species. Oliver is the recognized world authority on the subfamily Ericoideae.
Vitis bryoniifolia is a prolific and adaptable, polygamo-dioecious species of climbing vine in the grape family native to China, where it is known as ying yu(Traditional Chinese: 蘡薁 Simplified Chinese: 蘡薁), or hua bei pu tao. The variant form ternata is known as san chu ying yu （Traditional and Simplified Chinese: 三出蘡薁), meaning Three-Spiked-Leafed Ying Yu.

It has angular branches off its main stem, and its flowers usually have five white petals each. The specific epithet (tortuosum) is from Latin, describing something that is winding or very twisted.
