Question: Greyia and Calliandra, are which type of entity?

full_context: Document 1: Lomatium grayi: Lomatium grayi, commonly known as Gray's biscuitroot, Gray's lomatium, or milfoil lomatium, is a perennial herb of the family Apiaceae. It is native to Western Canada in British Columbia, and the Western United States, including from the Eastern Cascades and northeastern California to the Rocky Mountains.
Document 2: Calliandra tweediei: Calliandra tweediei is a species of flowering plants of the genus "Calliandra" in the Fabaceae family.
Document 3: Greyia: Greyia is a genus of plant in family Melianthaceae. It contains three species:
Document 4: Calliandra tergemina: Calliandra tergemina is a species of flowering plants of the genus "Calliandra" in the Fabaceae family.
Document 5: List of Grewia species: The large flowering plant genus Grewia is today placed by most authors in the mallow family Malvaceae, in the expanded sense as proposed by in the APG. Formerly, it was placed in either the linden family (Tiliaceae) or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of "Grewia" and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, "Grewia" is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus.
Document 6: Calliandra: Calliandra is a genus of flowering plants in the pea family, Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It contains about 140 species that are native to tropical and subtropical regions of the Americas.
Document 7: Calliandra physocalyx: Calliandra physocalyx is a species of flowering plants of the genus "Calliandra" in the Fabaceae family, endemic to southwestern Mexico. It is a shrub with pink-and-white or pink-and-red flowers. Like other members of the genus "Calliandra", the filaments of the stamens are long and colourful, in this case about 7.5 cm long. The species was first scientifically described in 1988.
Document 8: Calliandra calothyrsus: Calliandra calothyrsus is a small leguminous tree or large shrub in the Fabaceae family. It is native to the tropics of Central America where its typical habitat is wet tropical forests or seasonally dry forests with a dry season of four to seven months, when it may become deciduous. This tree grows to about 6 m and has pinnate compound leaves and flowers with a boss of prominent reddish-purple stamens. It is not very drought-tolerant and the above-ground parts are short-lived but the roots regularly resprout.
Document 9: Shortia: Shortia is a small genus of subshrubs or perennial herbs in the family Diapensiaceae. There are five species, four in Asia and one in the Appalachian Mountains of eastern North America. They are found in mountainous areas, generally from 1000 – elevation. All have restricted ranges and are generally considered rare. Three of the species, "S. galacifolia", "S. soldanelloides", and "S. uniflora" are often cultivated. The genus was by Asa Gray named after botanist Charles Wilkins Short. In Gray's diary entry for April 8, 1839, he named the genus after Charles Wilkins Short because the plant was native to America in a region close to where Short lived, which was Kentucky. Short and Gray never met but they corresponded with one another frequently. Short never saw a live nor dried specimen of his namesake genus.
Document 10: Grewia: The large flowering plant genus Grewia is today placed by most authors in the mallow family Malvaceae, in the expanded sense as proposed by in the APG. Formerly, it was placed in either the linden family (Tiliaceae) or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of "Grewia" and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, "Grewia" is in the subfamily Grewioideae and therein the tribe Grewieae, of which it is the type genus.
Document 11: Calliandra peninsularis: Calliandra peninsularis is a species of flowering plants of the genus "Calliandra" in the Fabaceae family.
Document 12: Calliandra riparia: Calliandra riparia is a species of flowering plants of the genus "Calliandra" in the Fabaceae family.
Document 13: Melaleuca: Melaleuca is a genus of nearly 300 species of plants in the myrtle family, Myrtaceae, commonly known as paperbarks, honey-myrtles or tea-trees (although the last name is also applied to species of "Leptospermum"). They range in size from small shrubs that rarely grow to more than 1 m (3 ft) high, to trees up to 35 m (100 ft). Their flowers generally occur in groups, forming a “head” or “spike” resembling a brush used for cleaning bottles, containing up to 80 individual flowers. They are superficially like "Banksia" species, which also have their flowers in a spike, but the structures of individual flowers in the two genera are very different.
Document 14: Calliandra erythrocephala: Calliandra erythrocephala is a species of flowering plants of the genus "Calliandra" in the Fabaceae family, endemic to southwestern Mexico. It is a small tree with bright red flowers. Like other members of the genus "Calliandra", the filaments of the stamens are long and colourful, in this case about 4.5 – long. The species was first scientifically described in 1988.
Document 15: Grahamia australiana: Grahamia australiana is a species of plant from the family Anacampserotaceae which is endemic to Australia, it is often better known as "Anacampseros australiana" but the genus "Anacampseros" is now thought to be restricted to Africa.
