Question: Croton is an extensive flowering plant genus in the spurge family, what family does Aristotelia a genus with 18 species, of tree belong to?
Context: Anthostema is a flowering plant genus in the Family Euphorbiaceae (spurge family) first described as a genus in 1824.  It is native to Africa and Madagascar. Euphorbia mellifera (canary spurge, honey spurge) is a species of flowering plant in the spurge family Euphorbiaceae, native to Madeira and the Canary islands.  It is an evergreen shrub growing to 2 m or more, with narrow leaves up to 20 cm long.  In spring it produces brown, honey-scented flowers. Croton is an extensive flowering plant genus in the spurge family, Euphorbiaceae.  The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius.  The common names for this genus are rushfoil and croton, but the latter also refers to "Codiaeum variegatum".  The generic name comes from the Greek κρότος ("krótos "), which means "tick" and refers to the shape of the seeds of certain species. Dichostemma is a flowering plant genus in the Family Euphorbiaceae (Spurge family) first described as a genus in 1896.  It is native to tropical western and central Africa. Croton glandulosus has many common names such as vente conmigo, tooth-leaved croton, tropic croton and sand croton.  It is part of the Euphorbiaceae family which is also known as the Spurge Family and it contains about 321 genera and 7,950 species.  The family derives its name from Euphorbus who was a Trojan War hero in Greek mythology, and was also the Greek Physician of King Juba of Numidia.  The genus, Croton, is derived from Greek, meaning “tick,” and this is because the seeds of the plant resemble a tick.  The species, glandulosus gets its name from the gland like structures that appear at the end of the leaf stalk.  Vente conmigo and various others species are found to be common weeds in gardens and lawns. Croton nepetifolius (Croton nepetaefolius) is an aromatic species of flowering plant in the spurge family, Euphorbiaceae, that is native to northeastern Brazil.  It is commonly known as "marmeleiro vermelh" (red quince).  The plant has been used in folk medicine as a sedative, an orexigenic (appetite enhancer) and an antispasmodic (muscle contaction suppressor). Croton monanthogynus, commonly called prairie tea, is a species of flowering plant in the spurge family.  It is a summer annual that producer small, inconspicuous flowers.  It is native to the southeastern United States and the southern Great Plains.  It occurs in sunny, dry habitats, of both disturbed and high-quality areas. Aristotelia is a genus with 18 species, of tree in the family Elaeocarpaceae.  It is named in honor of the Greek philosopher Aristoteles. Croton lechleri is a species of flowering plant in the spurge family, Euphorbiaceae, that is native to northwestern South America.  It is commonly known as Sangre de Grado (Peruvian Spanish) or Sangre de Drago (Ecuadorian Spanish), both of which translate to "dragon's blood".  They refer to this tree's (and several related species') thick red latex. Claoxylon is a flowering plant genus in the spurge family, Euphorbiaceae, comprising dioecious subshrubs to small trees.  It was first described as a genus in 1824.  The genus is distributed in paleotropical areas: Madagascar through South and Southeast Asia, Malesia to Melanesia, Hawaiʻ i, and Australia.  Half of the species are in Malesia.  According to a molecular phylogenetic study by Wurdack, Hoffmann & Chase (2005), "Claoxylon" is sister to "Erythrococca" (50 species, Africa), and together they form the top of a Hennigian comb-like phylogeny.
Answer: Elaeocarpaceae
