Question: Are both Hippophae and Pelargonium genera of sea buckthorns?

full_context: Document 1: Hippophae: Hippophae is a genus of sea buckthorns, deciduous shrubs in the family Elaeagnaceae. The name sea buckthorn may be hyphenated to avoid confusion with the buckthorns ("Rhamnus", family Rhamnaceae). It is also referred to as sandthorn, sallowthorn, or seaberry.
Document 2: Gerrardina: Gerrardina is a genus of two species of trees, shrubs, and scrambling shrubs found in southeastern Africa. Until recently, the genus was placed in the polyphyletic family Flacourtiaceae, but it was abnormal there due to its apical placentation, small embryos, and mucilaginous foliar epidermis. Analyses of DNA data indicated that the genus did not fit in any known plant family and not clearly in any then-recognized order, and a new family, Gerrardinaceae, was thus created for it. Later analyses of additional DNA data and data from wood anatomy indicated that the family should be placed in the order Huerteales.
Document 3: Hippophae rhamnoides: Hippophae rhamnoides, also known as common sea buckthorn is a species of flowering plant in the family Elaeagnaceae, native to the cold-temperate regions of Europe and Asia. It is a spiny deciduous shrub. The plant is used in the food and cosmetic industry, in traditional medicine, as animal fodder and for ecological purposes.
Document 4: Geraniaceae: Geraniaceae is a family of flowering plants placed in the order Geraniales. The family name is derived from the genus "Geranium". The family includes both the genus "Geranium" (the cranesbills, or true geraniums) and the garden plants called geraniums, which modern botany classifies as genus "Pelargonium", along with other related genera.
Document 5: Phygelius: Phygelius, common names Cape fuchsia or Cape figwort, is a genus of flowering plants in the Scrophulariaceae family, native to wet slopes and banks in southern Africa. They are evergreen shrubs often treated as perennials in colder climates. They bear many pendent tubular flowers over a long period in summer, in shades of white, yellow and red. The vague similarity of the blooms to fuchsias has led to the common name Cape fuchsia, though they are not closely related.
Document 6: Sarcopoterium: Sarcopoterium is a genus of flowering plants in the rose family. The genus is synonymous to "Poterium". The sole species within this genus, Sarcopoterium spinosum, is common to the southeast Mediterranean region and Middle East. It is a perennial bush with small flowers in inflorescence. "Sarcopoterium spinosum" flowers in February to April and its fruits mature in autumn, then fall to earth to germinate with the rain water.
Document 7: Sea buckthorn oil: Sea buckthorn oil is derived from plants in a group of species of the genus "Hippophae", the most commonly used of which is "Hippophae rhamnoides". As species belonging to this genus accumulate lipids in the mesocarp (the fleshy part of the fruit), oil can be extracted from either the seeds or the pulp of the fruit. The resulting oil is used in cosmetics and skin care products.
Document 8: Ceropegia: Ceropegia is a genus of plants within the family Apocynaceae, native to Africa, southern Asia, and Australia. It was named by Carl Linnaeus, who first described this genus in volume 1 of his "Species plantarum", which appeared in 1753. Linnaeus thought that the flowers looked like a fountain of wax. From this the scientific name was derived: ‘"keros"’ meaning wax and ‘"pege"’ meaning fountain (Pooley, 1998). They have many common names including lantern flower, parasol flower, parachute flower, bushman’s pipe, string of hearts, snake creeper, wine-glass vine, rosary vine, and necklace vine.
Document 9: Sambucus: Sambucus is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus "Adoxa". In "Sambucus", there are between 5 and 30 species of deciduous shrubs, small trees and herbaceous perennial plants.
Document 10: Salicornia: Salicornia is a genus of succulent, halophyte (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. "Salicornia" species are native to North America, Europe, South Africa, and South Asia. Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in "Salicornia". The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus, usually as <nowiki>'</nowiki>sea beans<nowiki>'</nowiki> or samphire greens or sea asparagus .
Document 11: Sagina: Sagina (like "Colobanthus" called "pearlworts") is a genus of 20–30 species of flowering plants in the pink or carnation family, Caryophyllaceae. These are flowering herbs native to temperate regions of the Northern Hemisphere extending south to tropical mountain areas at high altitudes, reaching just south of the equator in Africa. They are small annual or perennial herbaceous plants, growing to 5–15 cm. The leaves are opposite, often in tight whorl-like clusters, simple linear, typically 5–20 mm long. The flowers are solitary or in small cymes, with four or five green sepals and an equal number of white petals; the petal size relative to the sepal size is useful in species identification. The fruit is a small capsule containing several seeds.
Document 12: Rhamnus davurica: Rhamnus davurica is a species of flowering plant in the buckthorn family known by the common name Dahurian buckthorn. It is native to China, North Korea, Mongolia, eastern Siberia, and Japan. It is present in North America as an introduced species.
Document 13: Erica: Erica is a genus of roughly 860 species of flowering plants in the family Ericaceae. The English common names "heath" and "heather" are shared by some closely related genera of similar appearance. The genus "Calluna" was formerly included in "Erica" – it differs in having even smaller scale-leaves (less than 2–3 mm long), and the flower corolla consisting of separate petals. "Erica" is sometimes referred to as "winter (or spring) heather" to distinguish it from "Calluna" "summer (or autumn) heather".
Document 14: Darwinia (plant): Darwinia, sometimes commonly known as mountain bells or simply bells, is a genus of about 70 species of evergreen shrubs in the family Myrtaceae, endemic to southeastern and southwestern Australia. The majority are native to southern Western Australia, but a few species occur in South Australia, New South Wales and Victoria. The genus was named in honour of Erasmus Darwin, grandfather of Charles Darwin by Edward Rudge in 1816. Most darwinias grow to a height of between 0.2 and 3 m and many are prostrate shrubs. Most have small, simple leaves and the flowers are often grouped together, each flower with five red, white or greenish petals and ten stamens. In many species, the flowers are surrounded by large, colourful bracts, giving rise to their common names.
Document 15: Pelargonium: Pelargonium is a genus of flowering plants which includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums (in the United States also storksbills). Confusingly, "Geranium" is the botanical name (and also common name) of a separate genus of related plants often called cranesbills. Both genera belong to the family Geraniaceae. Linnaeus originally included all the species in one genus, "Geranium", and they were later separated into two genera by Charles L’Héritier in 1789.
