Diphasiastrum is a genus of clubmosses in the plant family Lycopodiaceae. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is placed in the subfamily Lycopodioideae. It is closely related to the genus Lycopodium, and some botanists treat it within a broad view of that genus as a section, Lycopodium sect. Complanata. Some species superficially resemble diminutive gymnosperms and have been given common names such as ground-pine or ground-cedar. There are 16 species, and numerous natural hybrids in the genus; many of the hybrids are fertile, allowing their occurrence to

Tradescantia pallida is a species of spiderwort native to the Gulf Coast region of eastern Mexico. It is a perennial herbaceous species with a trailing habit.

This plant is an evergreen, perennial pteridophyte. The spores are produced June to September.

Diphasiastrum alpinum, the alpine clubmoss, is a species of clubmoss. This plant is a glaucous scale-leaved perennial pteridophyte. In Finland, the spores are produced June to September. It was first described by Carl Linnaeus in his Flora Lapponica, 1737, from specimens obtained in Finland.

Oemleria cerasiformis, a shrub commonly known as osoberry, squaw plum, Indian plum, or Indian peach, is the sole extant species in the genus Oemleria. The deciduous and perennial shrub can grow up to 7 meters tall, with spreading branches that produce small white flowers and bitter fruit that only become sweet when fully ripe. Osoberry is dioecious, only female plants producing fruit, while males produce a high reproductive biomass of pollen and flowers. The flowers are insect and hummingbird-pollinated and the fruits are consumed by both birds and mammals, which later disperse the seeds in

Lemna turionifera is a species of flowering plant belonging to the family Araceae. The species is a floating freshwater aquatic plant, with one, two, three or four leaves each having a single root hanging in the water. Like its close relative Lemna minor, it reproduces primarily vegetatively. Unlike L. minor, however, the species is also capable of producing turions, which are starch-filled fronds that sink to the substrate and remain dormant until germinating when conditions are favorable. Its native range is Northern Europe to Japan, Northern America.

Dressleria is a genus of flowering plants from the orchid family, Orchidaceae native to South and Central America.

Cupressus gigantea, the Tibetan cypress, is a species of conifer in the family Cupressaceae in Asia. C. gigantea was previously classified as a subspecies of Cupressus torulosa because of their similar morphological characteristics and close distribution, but have since been genetically distinguished as separate species.

Leucanthemopsis is a genus of flowering plants in the daisy family. Species Leucanthemopsis alpina (L.) Heywood - central + southern Europe from Spain to Ukraine Leucanthemopsis flaveola (Hoffmanns. & Link) Heywood - Spain, Portugal Leucanthemopsis longipectinata (Font Quer) Heywood - Morocco Leucanthemopsis pallida (Mill.) Heywood - Spain Leucanthemopsis pallidaspathulifolia - Subbaetic Mountains in southern Spain Leucanthemopsis pectinata (L.) G.López & C.E.Jarvis - Morocco, Spain Leucanthemopsis pulverulenta (Lag.) Heywood - Spain, Portugal Leucanthemopsis trifurcatum (Desf.) Alavi -

Acacia simplex is a perennial climbing tree native to islands in the western part of the Pacific Ocean as far east as Savaiʻi. It is also found in Argentina. This tree grows up to 12 m in height.

Hypodematiaceae is a family of ferns in the order Polypodiales. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Hypodematioideae of a very broadly defined family Polypodiaceae sensu lato. The family consists of two, or in some versions three, small genera.

In Latin, the word panax means "cure-all", and the family of ginseng plants is one of the best-known herbs. Panax notoginseng grows naturally in China. The herb is a perennial with dark green leaves branching from a stem with a red cluster of berries in the middle. It is both cultivated

The Klebsormidiaceae are a family containing five genera of charophyte green alga forming multicellular, non-branching filaments. The genus Chlorokybus was previously included as well, but this problematic and poorly known genus is now placed in a separate class Chlorokybophyceae. Klebsormidiaceae are the sister to the Phragmoplastophyta. Their ancestor was probably a multicellular freshwater green algae, and multicellularity will be retained in all of its descendants except the Zygnematophyceae, which reverted back to unicellularity. Together with the unicellular Chlorokybophytina
