Wigandia is a genus of flowering plants within the waterleaf subfamily, Hydrophylloideae. They are found mainly in Central America and South America, though one or two species are found as far north as the United States. Some are grown as ornamental plants and will flourish in most Mediterranean or temperate regions. The genus is named for Johann Wigand (c. 1523–1587), German Lutheran cleric and theologian, and Bishop of Pomesania. [2]
Within the Hydrophylloideae, Wigandia species are unusual in having minute seeds and a high base chromosome number (19); it is also the only neotropical genus in the subfamily. [3]
Some species originally classified in Wigandia are now treated in other genera, e.g. Eriodictyon . There is a group of closely related genera within the Hydrophylloideae subfamily, and it is likely that further taxonomic work will result in additional reclassifications. A recent molecular phylogenetic analysis of the Hydrophylloideae [4] included two Wigandia species (W. caracasana and W. urens), and confirmed that they lay within a clade that includes Eriodictyon, and also the genera Nama and Turricula .
Six species are currently accepted. [1]
Species formerly classified within Wigandia include:
The Crassulaceae, also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium-sized monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus Sedum, and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic.
Bombacaceae were long recognised as a family of flowering plants or Angiospermae. The family name was based on the type genus Bombax. As is true for many botanical names, circumscription and status of the taxon has varied with taxonomic point of view, and currently the preference is to transfer most of the erstwhile family Bombacaceae to the subfamily Bombacoideae within the family Malvaceae in the order Malvales. The rest of the family were transferred to other taxa, notably the new family Durionaceae. Irrespective of current taxonomic status, many of the species originally included in the Bombacaceae are of considerable ecological, historical, horticultural, and economic importance, such as balsa, kapok, baobab and durian.
Stipa is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to Stipa, which have since been reclassified into new genera.
Hydrophylloideae is a subfamily of the plant family Boraginaceae. Its taxonomic position is somewhat uncertain. Traditionally, and under the Cronquist system, the taxon was given family rank under the name Hydrophyllaceae, and treated as part of the order Solanales. More recent systems have recognised a close relationship to the borage family, Boraginaceae, initially by placing Hydrophyllaceae and Boraginaceae together in an order Boraginales, and in the 2016 APG IV system by including Hydrophyllaceae in Boraginaceae. However, the placement and circumscription of Boraginaceae is still uncertain. Some sources now split off Hydrophyllaceae again.
Scilloideae is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari and Scilla and Puschkinia. Some are important as cut flowers.
The taxonomy of the Orchidaceae (orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera. De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789. Olof Swartz recognized 25 genera in 1800. Louis Claude Richard provided us in 1817 with the descriptive terminology of the orchids. (See External links below). The next step was taken in 1830-1840 by John Lindley, who recognized four subfamilies. He is generally recognized as the father of orchid taxonomy. The next important step was taken by George Bentham with a new classification, recognizing subtribes for the first time. This classification was first presented in a paper that Bentham read to the Royal Society in 1881. Then it was published in 1883 in the final volume of Genera Plantarum. The next great contributors were Pfitzer (1887), Schlechter (1926), Mansfeld (1937), Dressler and Dodson (1960), Garay (1960, 1972), Vermeulen (1966), again Dressler (1981). and Burns-Balogh and Funk (1986). Dressler's 1993 book had considerable influence on later work.
Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.
Boraginales is an order of flowering plants in the asterid clade, with a total of about 125 genera and 2,700 species. Different taxonomic treatments either include only a single family, the Boraginaceae, or divide it into up to eleven families. Its herbs, shrubs, trees and lianas (vines) have a worldwide distribution.
Wigandia caracasana, the Caracus wigandia, is a species of ornamental plant. It is an evergreen that grows to a height of up to 3 metres (10 ft). It has purple flowers in large clusters from spring to autumn. Some sources treat it as a variety of the species Wigandia urens. Native to Central America, it is thought to be naturalized in southern California as a garden escape. It is commonly grown in gardens, and thrives best in a mixture of loam and peat. Cuttings in sand will strike if placed under glass and in heat.
Eriodictyon is a genus of plants known by the common name yerba santa within the Hydrophylloideae subfamily of the borage family, Boraginaceae. They are distributed throughout the southwestern United States and Mexico.
Eriodictyon californicum is a species of plant within the family Boraginaceae. It is also known as yerba santa, mountain balm, bear's weed, gum bush, gum plant, and consumptive weed. Less common names include Herbe des Montagnes, Herbe à Ourse, Herbe Sacrée, Herbe Sainte, Hierba Santa, Holy Herb, and Tarweed.
Kageneckia is a genus of flowering plant in family Rosaceae.
Tournefortia, often called soldierbushes, is a genus of flowering plants in the borage family, Boraginaceae.
Epidendrum paniculatum is a species of orchid in the genus Epidendrum.
Eriodictyon parryi or poodle-dog bush is a tall California mountain shrub with showy purple flowers, which is notable for secreting a severe skin irritant. It is an opportunistic species that grows mostly in areas that have been disturbed by fire. In a dry early spring in Southern California, its semi-dormant leaves can droop and curl into coils like locks of curly hair, hence the popular name based on the metaphor of a poodle's natural hair.
Eriodictyon lobbii is a species of flowering plant in the borage family known by the common names Lobb's fiddleleaf and matted yerba santa. It is native to the Sierra Nevada and southern Cascade Range chain in California and adjacent sections of Nevada and Oregon. It grows in high mountain habitat in dry areas on slopes and ridges.
The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species.
The Solanaceae, or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell, and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
Morisonia is a genus of flowering plants in the family Capparaceae, found across the Americas from the United States to Argentina. They are typically shrubs or small trees. The genus was recently enlarged with New World Capparis species due to existing taxonomic instability.
