The Portulacaceae are a family of flowering plants, comprising 115 species in a single genus Portulaca. Formerly some 20 genera with about 500 species, were placed there, but it is now restricted to encompass only one genus, the other genera being placed elsewhere. The family has been recognised by most taxonomists, and is also known as the purslane family. It has a cosmopolitan distribution, with the highest diversity in semiarid regions of the Southern Hemisphere in Africa, Australia, and South America, but with a few species also extending north into Arctic regions. The family is very similar to the Caryophyllaceae, differing in the calyx, which has only two sepals.
Conyza is a genus of flowering plants in the family Asteraceae.
The Gnaphalieae are a tribe of flowering plants in the family Asteraceae. It is most closely related to the tribes Anthemideae, Astereae, and Calenduleae.
Baccharis is a genus of perennials and shrubs in the aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. B. halimifolia is commonly known as "groundsel bush", however true groundsels are found in the genus Senecio.
Haplopappus is a genus of flowering plants in the family Asteraceae found in South America, mostly restricted to the dry regions of the Southern Andes, Chilean Matorral, and Patagonia.

The Mutisioideae are a subfamily in the plant family Asteraceae that includes about 630 species assigned to 44 different genera. This subfamily is mainly native in South America, except for Adenocaulon, Chaptalia, Gerbera, Trichocline, which have species in all continents other than Europe and Antarctica. Common characters are the deeply incised corollas of the disc florets, with five lobes, sometimes merged in two lips, flower heads with overlapping involucral bracts, anthers with tails and pointy tips, the styles usually stick far out of the florets and are essentially hairless. Most species are herbs, but some are vines, shrubs, or small trees.
