Question: Both Bartlettina and Cucumis come from the aster family?

Context paragraphs:
Eurybia radula: Eurybia radula, commonly known as the low rough aster or rough wood aster, is an herbaceous perennial in the aster family.  It is native to eastern North America where it is present from Newfoundland and Labrador in the far northeast of Canada, west to Ontario and south to Kentucky and Virginia in the United States.  The low rough aster is also present on the French overseas territory of St. Pierre and Miquelon just south of Newfoundland.  It typically grows in wet soils in a wide variety of habitats from bogs and fens to creek shores to ditches.  Although it is not considered threatened over most of its distribution, it is imperiled or possibly extirpated over much of its range in the United States.  Its flower heads emerge in the late summer to early fall and show pale blue-violet rays with yellow centres.

Bartlettina campii: Bartlettina campii is a species of flowering plant in the aster family, Asteraceae.  It is endemic to Ecuador, where it is known from only one collection made in 1945 on the eastern slopes of the Andes in Morona-Santiago Province.  It is a liana collected from mountain forest habitat.

Symphyotrichum lanceolatum: Symphyotrichum lanceolatum (syn.  "Aster lanceolatus") is a species of flowering plant in the aster family, Asteraceae.  It is native to Canada and the United States.  Common names include panicled aster, tall white aster, eastern line aster, lance-leaf aster, narrow-leaf Michaelmas daisy, and white-panicle aster.

Aster yellows: Aster yellows is a chronic, systemic plant disease caused by a bacterium-like organism called a phytoplasma.  The aster yellows phytoplasma (AYP) affects 300 species in 38 families of broad-leaf herbaceous plants, primarily in the aster family, as well as important cereal crops such as wheat and barley.  Symptoms are variable and can include phyllody, virescence, chlorosis, stunting, and sterility of flowers.  The aster leafhopper vector, "Macrosteles quadrilineatus", moves the aster yellows phytoplasma from plant to plant.  Its economic burden is primarily felt in the carrot ("Daucus carota" ssp."  sativus") crop industry, as well as the nursery industry.  No cure is known for plants infected with aster yellows.  Infected plants should be removed immediately to limit the continued spread of the phytoplasma to other susceptible plants.  However, in agricultural settings such as carrot fields, some application of chemical insecticides has proven to minimize the rate of infection by killing the vector.

Almutaster: Almutaster is a North American genus of plants in the aster family containing the single species Almutaster pauciflorus (formerly "Aster pauciflorus"), which is known by the common name alkali marsh aster.  It is native to Canada (Northwest Territories and the 3 Prairie Provinces, the Western United States, and northern and central Mexico (as far south as Tlaxcala).

Cucumis: Cucumis is a genus of twining, tendril-bearing plants in the Cucurbitaceae family which includes the cucumber ("Cucumis sativus"), muskmelons ("Cucumis melo", including cantaloupe and honeydew), the horned melon ("Cucumis metuliferus"), and the West Indian gherkin ("Cucumis anguria").

Symphyotrichum pilosum: Symphyotrichum pilosum, commonly called the hairy white oldfield aster or frost aster, is an herbaceous plant in the aster family.

Bartlettina: Bartlettina is a genus of flowering plants in the aster family, Asteraceae.  They are native to tropical regions of Mesoamerica and South America.  The genus was erected to house several plants separated from genus "Eupatorium.

Eurybia paludosa: Eurybia paludosa, commonly known as the southern swamp aster, is an herbaceous perennial in the aster family.  It is native to the southeastern United States where it is confined to the Carolinas and the states of Georgia and Florida.  It is generally confined to moist soils, though it can occasionally be found on sand hills along the coastal plain.  The southern swamp aster is often confused with the closely related southern prairie aster ("Eurybia hemispherica"), though they do not occur in the same habitats or geographical areas.  Its flower heads emerge in the late summer through fall and show deep lavender to purple rays with yellow centres.

Chloracantha: Chloracantha is a monotypic genus of flowering plants in the aster family, containing the single species Chloracantha spinosa.  It is distributed in the southwestern and south-central United States (CA NV AZ UT NM TX OK LA), most of Mexico, and much of Central America.  Its English language common names include spiny chloracantha, spiny aster, devilweed aster, and Mexican devilweed.  In Spanish it is known as espina de agua, espinaza, and espinosilla.
