A pine is any conifer in the genus Pinus, /ˈpiːnuːs/,[1] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. The Plant List compiled by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 126 species names of pines as current, together with 35 unresolved species and many more synonyms.[2]
Sequoioideae (redwoods) is a subfamily of coniferous trees within the familyCupressaceae.[2] It is most common in the coastal forests of Northern California.
The three redwood subfamily genera are Sequoia and Sequoiadendron of California and Oregon, United States; and Metasequoia in China. The redwood species contains the largest and tallest trees in the world. These trees can live thousands of years. This is an endangered subfamily due to habitat losses from fire ecology suppression, logging, and air pollution.[citation needed]
Only two of the genera, Sequoia and Sequoiadendron, are known for massive trees. Metasequoia, with the living species Metasequoia glyptostroboides, are much smaller.

Ginkgo is a monotypic genus of highly unusual non-flowering plants. The scientific name is also used as the English name. The order to which it belongs, Ginkgoales, first appeared in the Permian,[4] 270 million years ago, possibly derived from “seed ferns” of the order Peltaspermales, and now only contains this single genus and species. The rate of evolution within the genus has been slow, and almost all its species had become extinct by the end of the Pliocene; the exception is the sole living species, Ginkgo biloba, which is only found in the wild in China, but is cultivated across the world. The relationships between ginkgos and other groups of plants are not fully resolved.

Vallisneria (named in honor of Antonio Vallisneri[3][4]) is a genus of freshwateraquatic plant, commonly called eelgrass, tape grass or vallis. The genus is widely distributed in tropical and subtropical regions of Asia, Africa, Europe, and North America.[2]
Vallisneria is a submerged plant that spreads by runners and sometimes forms tall underwater meadows. Leaves arise in clusters from their roots. The leaves have rounded tips, and definite raised veins. Single white female flowers grow to the water surface on very long stalks.[3] Male flowers grow on short stalks, become detached, and float to the surface.[3] The fruit is a banana-like capsule having many tiny seeds.[5][6]
Sometimes it is confused with the superficially similar Sagittaria when grown submerged.

Salvinia, a genus in the family Salviniaceae, is a floating fern named in honor of Anton Maria Salvini, a 17th-century Italian scientist. Watermoss is a common name for Salvinia.[1] The genus was published in 1754 by Jean-François Séguier, in his description of the plants found round Verona, Plantae Veronenses[2] Twelve species are recognized, at least three of which (S. molesta, S. herzogii, and S. minima) are believed to be hybrids, in part because their sporangia are found to be empty.
A fern is a member of a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having certain tissue that conducts water and nutrients, and having branched stems. Like other vascular plants, ferns have leaves, and these are “megaphylls”, which are more complex than the “microphylls” of clubmosses. Most ferns are leptosporangiate ferns, sometimes termed “true ferns”; they produce what are called “fiddleheads” that uncoil and expand into fronds.[3] The group includes about 10,560 known extant species.[4]
