Picrodendraceae is a family of flowering plants, consisting of 80 species in 25 genera. These are subtropical to tropical and found in New Guinea, Australia, New Caledonia, Madagascar, continental Africa, and tropical America. Its closest relatives are Phyllanthaceae. This family used to be known as the subfamily Oldfieldioideae of the Euphorbiaceae.

Triadica sebifera is a tree native to eastern Asia (Chinese 乌桕, wū jiù). It is commonly called Chinese tallow, Chinese tallowtree, Florida aspen, chicken tree, gray popcorn tree, or candleberry tree. The seeds (as well as from those of Triadica cochinchinensis) are the sources of stillingia oil, a drying oil used in paints and varnishes. The fatty coat of the seeds, used for candle and soap making, is known as stillingia tallow; hence its common name. It is relevant to biodiesel production because it is the third most productive vegetable oil producing crop in the world, after algae and oil

Quercus geminata, commonly called sand live oak, is an evergreen oak tree native to the coastal regions of the subtropical southeastern United States, along the Atlantic Coast from southern Florida northward to southeastern Virginia and along the Gulf Coast westward to southern Mississippi, on seacoast dunes and on white sands in evergreen oak scrubs.

Quercus austrina, the bastard white oak or bluff oak, is an oak species that is endemic to the Coastal Plain of the southeastern United States from Mississippi to South Carolina; previously reported populations in Arkansas and North Carolina were misidentifications. Quercus austrina can grow to a height of 45 to 60 feet (13.5–18 meters) with a spread of 35 to 50 feet (10.5–15 m). Leaves are narrow, with shallow rounded lobes. It tends to grow in wet habitats, such as on river bluffs, river bottoms, and flatwoods, and generally over basic substrates, such as mafic rocks, shells, or calcareous

The Maleae (incorrectly Pyreae) are the apple tribe in the rose family, Rosaceae. The group includes a number of plants bearing commercially important fruits, such as apples and pears, while others are cultivated as ornamentals. Older taxonomies separated some of this group as tribe Crataegeae, as the Cydonia group (a tentative placement), or some genera were placed in family Quillajaceae. The tribe consists exclusively of shrubs and small trees. Most have pomes, a type of accessory fruit that does not occur in other Rosaceae. All except Vauquelinia (with 15 chromosomes) have a basal haploid

Quercus fusiformis (also often referred to as Q. virginiana var. fusiformis), commonly known as escarpment live oak, plateau live oak, plateau oak, or Texas live oak, is an evergreen or nearly evergreen tree. Its native range includes the Quartz Mountains and Wichita Mountains in southwestern Oklahoma, through Texas (approximately from the Brazos River west up to the Pecos River and the southern Llano Estacado), to the Mexican states of Coahuila, Tamaulipas, and Nuevo León. Quercus fusiformis is an evergreen tree in the southern live oaks section of the genus Quercus (section Virentes). It is

Echinodorus grisebachii or Echinodorus amazonicus is commonly known as Amazon sword plant, although other plants are also known under this common name. The aquatic plant is cultivated for and used in ponds and artificial aquatic habitats. It is native to Cuba, Central America, and South America as far south as Brazil and Bolivia. It has been sold under the name Paniculatus.

Phyllonoma is a genus consisting of four species of trees and shrubs native to South and Central America, from Peru to Mexico. It is the sole genus in the family Phyllonomaceae, syn. Dulongiaceae. The flowers are produced in epiphyllous inflorescences, as in the Helwingiaceae; usually a pair of flowers at the tip of each leaf. The APG II classification (2003) places them in the order Aquifoliales, along with the hollies and Helwingiaceae. In the Cronquist classification (1981) the family Phyllonomaceae was treated as a synonym of the family Grossulariaceae, with the genus Phyllonoma included

Myrica cerifera is an evergreen tree or large shrub native to North and Central America and the Caribbean. Its common names include southern wax myrtle, southern bayberry, candleberry, bayberry tree, and tallow shrub. It has uses in the garden and for candlemaking, as well as a medicinal plant.

Ornithostaphylos is a monotypic plant genus which contains the single species Ornithostaphylos oppositifolia, commonly known as the Baja California birdbush or Baja California manzanita. A large, evergreen shrub in the heather family, this species is near-endemic to northwestern Baja California, with a small population just north of the border in San Ysidro, California. It produces a much-branched inflorescence of white, urn-shaped flowers, and has leathery leaves that appear opposite or in whorls. These characteristics separate it from its close relatives in the region, which include

Mecardonia procumbens (also known as yellow-flowered waterhyssop), common name baby jump-up, is an annual or perennial herb native to tropical and subtropical regions of the Americas. It has become widely spread in warmer regions worldwide, and is now naturalised on all continents except Antarctica, in addition to most islands with suitable climates.

Yeatesia is a putative genus of flowering plants in the family Acanthaceae, found in northeast Mexico and the southeast United States, from Texas to Florida. Each of its species grows in very different habitats; Yeatesia mabryi is found in hardwood forests in Mexico, Y. platystegia prefers semiarid scrublands in Mexico and Texas, and Y. viridiflora grows in wetter forest bluffs and along water courses in US Gulf Coast states. Molecular evidence shows that Yeatesia is not a monophyletic genus.

Havardia is a genus of flowering plants in the family Fabaceae. It belongs to the mimosoid clade of the subfamily Caesalpinioideae. It includes five species of trees native to the Americas, ranging from Texas and northern Mexico through Central America to Colombia and Venezuela. Typical habitats include warm-temperate and tropical seasonally-dry woodland, wooded grassland, and desert thorn scrub, typically below 450 meters elevation.

Acer leucoderme, the chalk maple, whitebark maple, or pale-bark maple) is a deciduous tree native to the southeastern United States from North Carolina south to northwest Florida and west to eastern Texas. It lives in the understory in moist, rocky soils on river banks, ravines, woods, and cliffs. Although generally an uncommon tree, it is most often found in the inner coastal plain and Piedmont regions of Georgia.

Persicaria punctata (syn. Polygonum punctatum) is a species of flowering plant in the knotweed family known by the common names dotted smartweed and dotted knotweed. Persicaria punctata is native to the Americas, where it can be found in moist and wet habitat types from Canada to Argentina including the West Indies. It is an extremely variable plant. It may be annual or perennial. Persicaria punctata grows from a rhizome and produces decumbent or erect stems which may just exceed one meter (40 in.) in length. The branching stems may root at nodes that come in contact with the substrate. The

Micranthes nivalis is a plant species in the saxifrage family. It is commonly called snow saxifrage or (ambiguously) alpine saxifrage. Micranthes nivalis is a perennial plant which grows on damp, shady, base-rich rocks and cliffs, usually in crevices and on ledges in locations where it cannot be crowded out by competing plants. In Britain the highest altitudes are recorded in Scotland, from 365 metres (1,198 ft) at the Quiraing, Isle of Skye, to 1,210 metres (3,970 ft) on Ben Lawers in Perth & Kinross. However it has been claimed as high as 1,300 metres (4,300 ft) in the Cairngorms. It grows
