Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera (Christenhusz & Byng 2016 ), almost entirely native to the Americas, from Central America to southern South America.
 One species of "Luzuriaga" occurs in New Zealand, and the genus "Drymophila" is endemic to south-eastern Australia.
Oenothera is a genus of about 145 species of herbaceous flowering plants native to the Americas.
 It is the type genus of the family Onagraceae.
 Common names include evening primrose, suncups, and sundrops.
 They are not closely related to the true primroses (genus "Primula").
Attalea crassispatha is a palm which is endemic to southwest Haiti.
 The most geographically isolated member of the genus, it is considered a critically endangered species and has been called one of the rarest palms in the Americas.
Phyllachne is a genus of four cushion plant species in the family Stylidiaceae.
 Of the four species, two are endemic to New Zealand, while "P. colensoi" is also native to Tasmania and "P. uliginosa" is entirely endemic to southern South America and is the only species in the Stylidiaceae native to the Americas.
 The movement of "P. colensoi" to colonize Tasmania is a relatively recent move.
 Molecular studies group "P. colensoi", "P. clavigera", and "P. rubra" together in one clade with "P. uliginosa" in the sister clade.
 Based on molecular clock data of the "rbcL" gene, it is estimated that "P. uliginosa" last shared a common ancestor with the New Zealand clade about 6 million years ago.
Eumycetoma is a chronic granulomatous fungal disease of humans, affecting mainly the limbs, and sometimes the abdominal and chest walls or the head.
 "Mycetoma pedis" (mycetoma of the foot), the most common form of mycetoma, is known widely as the Madura foot.
 The infection is endemic in Africa, India and the Central and South Americas.
Heterochromis is a genus of cichlid fish.
 It is the only genus of the subfamily Heterochromidinae, and contains a single species, Heterochromis multidens, which is endemic to the Congo River Basin in Central Africa.
 This species is more closely related to cichlids from the Americas rather than other African cichlids.
 It can reach a total length of 29.5 cm .
Enulius is a genus of snakes in the family Colubridae.
 The genus is endemic to the Americas.
Malaria Day in the Americas is commemorated annually on November 6 to promote awareness, recognize past and current efforts to prevent and control malaria in the region of the Americas, build commitment, and to mobilize action to advance malaria goals and targets as the region works towards elimination.
 Awareness of this disease is very important in the region of the Americas, where an estimated 120 million people in 21 endemic countries are at risk of malaria.
 In 2012, there were 469,000 confirmed malaria cases in the region with 108 deaths.
 Nonetheless, declining incidence of disease and malaria-related mortality has led to low prioritization of malaria on national health agendas in the Americas.
Choisya is a small genus of aromatic evergreen shrubs in the rue family, Rutaceae.
 Members of the genus are commonly known as Mexican orange or mock orange due to the similarity of their flowers with those of the closely related orange, both in shape and scent.
 They are native to southern North America, from Arizona, New Mexico, Texas and south through most of Mexico.
 In its generic name Humboldt and Bonpland honoured Swiss botanist Jacques Denis Choisy (1799–1859).
Oenothera harringtonii is a species of flowering plant in the evening primrose family known by the common names Arkansas Valley evening primrose and Colorado Springs evening primrose.
 It is endemic to the state of Colorado in the United States.

Question: Are both Choisya and Oenothera endemic to the Americas ?
Answer: yes
