Question: Dovyalis is a genus of shrubs and small trees belonging to the family Salicaceae, whereas Townsendia is a genus of NOrth American plants within what flower family?
Context: Acacia s.l. ( or ), known commonly as mimosa, acacia, thorntree or wattle, is a polyphyletic genus of shrubs and trees belonging to the subfamily Mimosoideae of the family Fabaceae.  It was described by the Swedish botanist Carl Linnaeus in 1773 based on the African species "Acacia nilotica".  Many non-Australian species tend to be thorny, whereas the majority of Australian acacias are not.  All species are pod-bearing, with sap and leaves often bearing large amounts of tannins and condensed tannins that historically found use as pharmaceuticals and preservatives. Abatia (syn.  "Raleighia" Gardner) is a genus of about ten species of Central and South American trees in the willow family Salicaceae (following the Angiosperm Phylogeny Group classification).  Previously it was treated in the family Flacourtiaceae, or tribe Abatieae of the family Passifloraceae (Lemke 1988) or Samydaceae by G. Bentham & J.D. Hooker and Hutchinson. Townsendia is a genus of North American plants in the aster tribe within the daisy family. Olearia is a genus of flowering plants belonging to the family Asteraceae.  There are about 130 different species within the genus found mostly in Australia, New Guinea and New Zealand.  The genus includes herbaceous plants, shrubs and small trees.  The latter are unusual among the Asteraceae and are called "tree daisies" in New Zealand.  All bear the familiar daisy-like composite flowerheads. Flacourtia is a genus of flowering plants in the willow family, Salicaceae.  It was previously placed in the now defunct family Flacourtiaceae.  The generic name honors Étienne de Flacourt (1607–1660), a governor of Madagascar.  It contains 15 species of shrubs and small trees that are native to the African and Asian tropics and subtropics.  Several species, especially "F. indica", are cultivated as ornamentals and for their fruits.  The trunks of small trees are often guarded by branching spines. Calpurnia is a genus of flowering plants within the family Fabaceae.  The genus comprises shrubs or small trees in or along the margin of forests in the eastern parts of South Africa.  They shed leaves in winter unless in moist areas, where they are evergreen.  They make good garden plants because they are easily raised from seed, flower at two years and withstand frost. Dovyalis is a genus of shrubs and small trees. Recent genetic evidence has shown the genus to belong to the family Salicaceae; formerly it was classified in the family Flacourtiaceae.  The 15 species are native to Africa (Ethiopia south to South Africa) and southern Asia (India, Sri Lanka).  Some are cultivated for their fruit. Denhamia is a genus of plants within the family Celastraceae, with species in Australia and New Caledonia.  The species inhabit a variety of environments, from rainforest to semi-arid savanna.  All species grow as shrubs or small trees up to 10 metres in height.  The genus is composed of nine species, with two currently unnamed species: Argophyllaceae is a family of shrubs or small trees belonging to the order Asterales.  The family includes two genera "Argophyllum" and "Corokia".  Members of the family are native to eastern Australia, New Zealand, Lord Howe Island, New Caledonia, and Rapa Iti. Pisonia is a genus of flowering plants in the four o'clock flower family, Nyctaginaceae.  It was named for Dutch physician and naturalist Willem Piso (1611–1678).  Certain species in this genus are known as catchbirdtrees, birdcatcher trees or birdlime trees because their sticky seeds reportedly trap small birds.  These sticky seeds are postulated to be an adaptation of some island species to ensure the dispersal of seeds between islands by attaching them to birds.  These island species include "P. brunoniana" of Australasia and Polynesia and "P. umbellifera", which is widespread in the tropical Indo-Pacific region.
