Ceanothus Ceanothus L. is a genus of about 50–60 species of nitrogen-fixing shrubs or small trees in the family Rhamnaceae. Common names for members of this genus are California lilac, wild lilac, and soap bush. ""Ceonothus"" comes from a Greek word meaning "spiny plant", Ancient Greek: κεάνωθος ("keanōthos"), which was applied by Theophrastus (371–287 BC) to an Old World plant believed to be "Cirsium arvense".

Cactus A cactus (plural: "cacti", "cactuses", or "cactus") is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word "cactus" derives, through Latin, from the Ancient Greek κάκτος , "kaktos", a name originally used by Theophrastus for a spiny plant whose identity is not certain. Cacti occur in a wide range of shapes and sizes. Most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water. Almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, which are highly modified leaves. As well as defending against herbivores, spines help prevent water loss by reducing air flow close to the cactus and providing some shade. In the absence of leaves, enlarged stems carry out photosynthesis. Cacti are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north—except for "Rhipsalis baccifera", which also grows in Africa and Sri Lanka.

Desmanthus Desmanthus is a genus of flowering plants in the mimosoid clade of the subfamily Caesalpinioideae of the pea family, Fabaceae. The name is derived from the Greek words δεσμός ("desmos"), meaning "bundle", and ἄνθος ("anthos"), meaning "flower". It contains about 24 species of herbs and shrubs that are sometimes described as being suffruiticose and have bipinnate leaves. "Desmanthus" is closely related to "Leucaena" and in appearance is similar to "Neptunia". Like "Mimosa" and "Neptunia", "Desmanthus" species fold their leaves in the evening. They are native to Mexico and North, Central and South America. Members of the genus are commonly known as bundleflowers. Donkey beans is another common name and originated in Central America, where "Desmanthus" species are highly regarded as fodder for these domestic draught animals.

Juglans Walnut trees are any species of tree in the plant genus Juglans, the type genus of the family Juglandaceae, the seeds of which are referred to as walnuts. All species are deciduous trees, 10 – tall, with pinnate leaves 200 – , with 5–25 leaflets; the shoots have chambered pith, a character shared with the wingnuts ("Pterocarya"), but not the hickories ("Carya") in the same family.

Clusiaceae The Clusiaceae or Guttiferae ("nom. alt. et cons." = alternative and valid name) are a family of plants including 13 genera and ca 750 species. Several former members of Clusiacae are now placed in Calophyllaceae and Hypericaceae. They are mostly trees and shrubs, with milky sap and fruits or capsules for seeds. The family is primarily tropical. More so than many plant families, it shows large variation in plant morphology (for example, three to 10, fused or unfused petals, and many other traits). According to the APG III, this family belongs to the order Malpighiales.

U.S. Virgin Islands Dry Forest A Dry Forest are defined as a community of trees of different species that coexist in the same environment. These trees can grow nearby forming a canopy above. Dry forests lack an abundance of moisture, yet, there is an adequate amount of moisture to sustain the growth of the forest. Although dry forest tends to grow at an intermediate height compared to moist forest. Dry forest receives 850-1100mm of precipitation per year. High quantities of sea salt from the ocean decreases the height of the trees. Dry forest also consisted of layers of canopies, specifically two canopy layers that commonly found at an elevation below 300 meters. There is limited dead dry wood for termites to consume, this correlates with low density of termites in dry forests. The characteristics and development of Virgin Islands Dry Forest are contributed by a unique wind pattern that is usually strong. Dry Forest usually thrive in environments that have plenty sunshine, steep slopes, on soil that are challenged by thin rocky layers that poorly absorbs water. Within the three islands in the United States Virgin Islands, St. John has maintained a higher percentage of dry forest cover competing with St. Thomas at 43.1%; St. Croix has limited dry forest cover (9.22%). St. John and St. Thomas topography has significant steep hills and slopes compared to St. Croix. St. John is the most protected of the three islands, and as such it has the largest extensive tropical dry forests in the U.S. Virgin Islands. The island contains 650 native plants, 5,000 or more terrestrial insects, over 180 species of birds, of which 90% are native, and six native mammal bat species. One of the most common trees in the “native dry forest garden” is the amarat. They are acacias, (casha bush) but do not have thorns likes most other varieties.

Schinopsis balansae Schinopsis balansae is a hardwood tree known as willow-leaf red quebracho which forms forests in the subtropical Gran Chaco ecoregion of north-eastern Argentina, and Paraguay. It is also found in the wild Pantanal vegetation in Brazil. Some of its vernacular names are "quebracho colorado chaqueño" and "quebracho santafesino". Other species, like "Schinopsis lorentzii", bear the general name quebracho and have similar properties and uses. "S. balansae" shares its habitat with a species of the same genus, "S. heterophylla", and the two are often confused.

Cajeput tree Cajeput tree is a common name used for certain classification of tree that has a white spongy bark that is flexible and can easily flake off the trunk. The Cajeput tree is of the genus "Melaleuca", native to Australia and is commonly known in North America as the Tea Tree. The name "Cajeput tree" is primarily used for the species "M. cajuputi", "M. leucadendra", "M. linariifolia", "M. viridiflora" and "M. quinquenervia". Other names for these trees are the paperbark tree, punk tree, or the white bottle brush tree. Similar subtropical trees from the eucalyptus family are evergreens with pointed leaves and white, red or green flowers. Aborigines of Australia often used the cajeput tree bark for shields, canoes, roofing material and timber.

List of largest giant sequoias The giant sequoia ("Sequoiadendron giganteum") is the world's most massive tree, and arguably the largest living organism on Earth. It is neither the tallest extant species of tree (that distinction belongs to the coast redwood), nor is it the widest (that distinction belongs to the baobab tree or Montezuma Cypresses), nor is it the longest-lived (that distinction belongs to the Great Basin bristlecone pine). However, with a height of 286 ft or more, a circumference of 113 ft or more, an estimated bole volume of up to 52500 ft3 , and an estimated life span of 1800–2700 years, the giant sequoia is among the tallest, widest and longest-lived of all organisms on Earth.
