Arctium minus, commonly known as lesser burdock, little burdock, louse-bur, common burdock, button-bur, cuckoo-button, or wild rhubarb, is a biennial plant native to Europe.

Dicentra (Greek dís "twice", kéntron "spur"), known collectively as the bleeding-hearts, is a genus containing eight species of herbaceous flowering perennial plants with unique, "heart"-shaped flowers and finely divided foliage. The species are, primarily, native to North America, although several are found in temperate East Asia.

Pulicaria dysenterica, the common fleabane, or, in North America, meadow false fleabane, is a species of fleabane in the family Asteraceae. It is native to Europe and western Asia where it grows in a variety of habitats ranging from semi-arid Mediterranean woodlands to wetter situations. Pulicaria dysenterica is perennial and can form dense clusters of plants, spreading by its roots. It flowers at its maximum height of about 60 centimetres (2.0 ft). Leaves are alternately arranged and clasp the stem, which itself contains a salty-astringent liquid. The yellow inflorescences are typically

Lathyrus vernus, the spring vetchling, spring pea, or spring vetch, is a species of flowering herbaceous perennial plant in the genus Lathyrus, native to forests of Europe and Siberia. It forms a dense clump of pointed leaves with purple flowers in spring, shading to a greenish-blue with age. This species, and the cultivar 'Alboroseus', have gained the Royal Horticultural Society's Award of Garden Merit.

Huperzia is a genus of lycophyte plants, sometimes known as the firmosses or fir clubmosses; the Flora of North America calls them gemma fir-mosses. This genus was originally included in the related genus Lycopodium, from which it differs in having undifferentiated sporangial leaves, and the sporangia not formed into apical cones. The common name firmoss, used for some of the north temperate species, refers to their superficial resemblance to branches of fir (Abies), a conifer. As of 2020, two very different circumscriptions of the genus were in use. In the Pteridophyte Phylogeny Group

Lathyrus niger, also known as black pea, blackening flat pea and black bitter vetch, is a perennial legume that is native to Europe. Its common name is reference to the blackening of the plant's foliage as it dies. The seeds of the species are not to be confused with edible 'black peas', which are a form of Pisum sativum. Seeds of Lathyrus species are toxic, containing an enzyme that interferes with collagen synthesis to cause the disease Lathyrism.

Cystopteris fragilis is a species of perennial fern known by the common names brittle bladder-fern and common fragile fern. It can be found worldwide, generally in shady, moist areas.

Falcaria vulgaris, the sickleweed or longleaf, is the sole species in the genus Falcaria. It is a biennial herb of the spherical shape. Blossoms in June–July. Grows in Europe, Siberia, Middle East, Northern Africa, North and South Americas. Contains alkaloids, carotene, vitamin C, proteins. Its use as an alternative medicine may offer several advantages, especially in the treatment of stomach and skin ulcers, diabetes, infections, and liver and kidney disorders.

Veratrum lobelianum is a species of flowering plant belonging to the family Melanthiaceae. Its native range is Central Europe to Caucasus and Russian Far East. The plant is poisonous. It is used in Chinese folk medicine. In Russia, it is available as a tincture ("Veratrum Aqua") that is intended for external use and is toxic if ingested (accidentally or in folk medicine).

Cystopteris is a genus of ferns in the family Cystopteridaceae. These are known generally as bladderferns or fragile ferns. They grow in temperate areas worldwide. This is a very diverse genus and within a species individuals can look quite different, especially in harsh environments where stress stunts their growth. They hybridize easily with each other and identifying an individual can be challenging. In general these are rhizomatous perennials which grow in rocks or soil. Their leaves are multiply pinnate, in that each leaflet is divided into smaller parts. The sori are usually rounded and

Tmesipteris, the hanging fork ferns, is a genus of ferns, one of two genera in the family Psilotaceae, order Psilotales (the other being Psilotum). Tmesipteris is restricted to certain lands in the Southern Pacific, notably Australia, New Zealand and New Caledonia. In New Zealand this hanging epiphyte is common in the warm temperate rain forests of both main islands, where it can normally be found as short spiky dark-green fronds (10–15 cm long), often with lighter bag-like sporangia at the bases of some of its "leaves". The plant possesses no true leaves; what appear to be leaves are

Dennstaedtia is a mostly tropical and subtropical group of ferns described as a genus in 1801. Hayscented fern, or cup ferns, are common names for some species in this genus. It includes 58 species native to the tropical Americas, Madagascar, southern and eastern Asia, Australia, New Guinea, and the Pacific Islands. Some characteristics of Dennstaedtia: "Fronds homomorphic; stipe grooved above, hairy when young... lamina triangular to oblong, many times pinnate, usually densely hairy, especially on rachis... Veins free, pinnately branching, veinlet not reaching margin, with hydathode at apex.

Asplenium fontanum, commonly known as fountain spleenwort or smooth rock spleenwort, is a species of fern in the family Aspleniaceae, native to rocky areas in Western Europe.

Sphaeropteris medullaris, synonym Cyathea medullaris, commonly known as mamaku or black tree fern, is a large tree fern up to 20 m (66 ft) tall with a trunk up to 20 cm diameter at breast height. It is distributed across the south-west Pacific from Fiji to Pitcairn Island and is a common plant found in forests of New Zealand.

Datura discolor, also called the desert thorn-apple, is an herbaceous annual plant native to the Sonoran Desert of western North America, where it grows in sandy soils and washes. All parts of the plant contain a mix of alkaloids that are potentially lethal when enough is ingested.

Dicranopteris (forkedfern) is a genus of tropical ferns of the family Gleicheniaceae. There are about 20 described species.

Viscaria is a genus of flowering plants in the family Caryophyllaceae, native to Canada, Greenland, Iceland, Europe, Kazakhstan, and western Siberia. Molecular studies attempting to resolve relationships in the tribe Sileneae have found that Viscaria is closely genetically related to the genus Atocion, but is quite distinct from it morphologically.

Platycapnos is a genus of flowering plants belonging to the family Papaveraceae. Its native range is Canary Islands, Western and Central Mediterranean. Species: Platycapnos saxicola Willk. Platycapnos spicatus (L.) Bernh. Platycapnos tenuilobus Pomel

Dicentra cucullaria, Dutchman's britches, or Dutchman's breeches, is a perennial herbaceous plant, native to rich woods of eastern North America, with a disjunct population in the Columbia Basin. The common name Dutchman's breeches derives from their white flowers that look like white breeches.

Sphaeropteris is a genus of tree ferns in the family Cyatheaceae. It has been treated as a subgenus within the genus Cyathea, but is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

Cystopteris bulbifera, with the common name bulblet fern, bulblet bladderfern, or bulblet fragile fern is a fern in the family Cystopteridaceae.

Tmesipteris tannensis is a fern ally endemic to New Zealand. It is usually epiphytic on trees and tree ferns, but is occasionally terrestrial. An example of occurrence of T. tannensis within a tiered phytocoenosis is in Central Westland of South Island, New Zealand. These forests are the most extensive continuous podocarp/broadleaf forests in New Zealand. The overstory includes miro, rimu and mountain tōtara. The mid-story includes tree ferns such as Cyathea smithii and Dicksonia squarrosa, whilst the lowest tier and epiphytic associates include Asplenium polyodon, Astelia solandri and
