Are both Burchellia and Ixiolirion flowering plants?
Burchellia Burchellia is a monotypic genus of flowering plants in the Rubiaceae family. The genus contains only one species, viz. "Burchellia bubalina", which is endemic to southern Africa: the Cape Provinces, KwaZulu-Natal and the Northern Provinces in South Africa, and Swaziland. It is commonly known as "wild pomegranate" (English) or "wildegranaat" (Afrikaans).
Buellia disciformis Buellia disciformis (boreal button lichen) is a thin, bluish to pale gray rimose to areolate crustose lichen that grows on bark (rarely also on wood) in temperate forests in the northern USA and Europe, and at high altitudes in Arizona, down to 500 m in coastal areas of California.
