Question: Which plant is a species in the Ericaceae family, Gaultheria or Basselinia?
Context: "Gaultheria nummularioides" is a species of plant in the family Ericaceae.  It is distributed across India, Myanmar, Nepal, Bhutan, Indonesia, and Southwest China (Tibet, Yunnan, and Sichuan).  The plant grows in areas between 1,700 and 3,000 m above sea level, and grows better on rocky mountainsides and weed tree forests.  This species has been cultivated as an ornamental in Britain, the United States, and elsewhere for some decades. Rhododendron album is a species of plant in the Ericaceae family.  It is endemic to Java in Indonesia.  It is a vulnerable species threatened by habitat loss. Gaultheria procumbens, also called the eastern teaberry, the checkerberry, the boxberry, or the American wintergreen, is a species of "Gaultheria" native to northeastern North America from Newfoundland west to southeastern Manitoba, and south to Alabama.  It is a member of the Ericaceae (heath family). The Exobasidiaceae are a family of fungi in the Basidiomycota, Exobasidiales order.  The family contains 5 genera and 56 species.  Species in the family have a widespread distribution, especially in temperate areas.  Members of the Exobasidiaceae are plant pathogens that grow on the leaves of plants, especially those in the Ericaceae family. Gaultheria is a genus of about 135 species of shrubs in the family Ericaceae.  The name commemorates Jean-François Gauthier of Quebec, an honour bestowed by the Scandinavian Pehr Kalm in 1748 and taken up by Carl Linnaeus in his "Species Plantarum ".  These plants are native to Asia, Australasia and North and South America.  In the past, the Southern Hemisphere species were often treated as the separate genus "Pernettya", but no consistent reliable morphological or genetic differences support recognition of two genera, and they are now united in the single genus "Gaultheria". Erica ventricosa is a species of plant in the Ericaceae family native to the Afrotropics. Empetrum rubrum, known as red crowberry or diddle-dee (Chilean Spanish: "Murtilla de Magallanes"), is a species of plant in the Ericaceae family with a distributional range in Chile from Talca (35°S) to Cape Horn (55°S); in areas of adjacent Argentina; in the Falkland Islands; and in Tristan da Cunha.  One of its northernmost natural growing places is Laguna del Maule.  In Chile this species often grows in high altitude areas close to the tree line and can tolerate alpine conditions such as strong winds and high sun exposure.  In the Falkland Islands it is the dominant species across large areas of lowland and upland dwarf shrub heath, and is referenced in the islands' unofficial national anthem.  Its fruits are edible. Lyonia ovalifolia is a species of plant in the Ericaceae family.  This plant is Native to Nepal, China, Japan, Cambodia, Myanmar, Thailand, Vietnam and Malaysia. Rhododendron wilhelminae is a species of plant in the Ericaceae family.  It is endemic to Java in Indonesia.  It is a critically endangered species threatened by habitat loss. Basselinia is a genus of flowering plant in the Arecaceae family.  The entire genus is endemic to the Island of New Caledonia in the Pacific.  In some (but not all) molecular phylogenetic analyses, "Hedyscepe" from Lord Howe Island is nested in "Basselinia".
Answer: Gaultheria
