Boopis Anthemoides
''Boopis'' is a genus of flowering plants in the family Calyceraceae, which includes two species native to Argentina, central Chile, and Uruguay. The taxon formerly included more species. It was found to be highly polyphyletic A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies ..., and several species were moved to other genera.Silvia S. Denham, Nicolás F. Brignone, Leigh A.

Calyceraceae
Calyceraceae is a plant family in the order Asterales. The natural distribution of the about sixty species belonging to this family is restricted to the southern half of South America. The species of the family resemble both the family Asteraceae and the Dipsacaceae. Description Calyceraceae are perennial or annual herbs. There may be a few or many branched stems that may be without hair or with soft silky hairs. The leaves may be in a rosette at the base of the stems or set alternately along the stems. Stipules are lacking. The blade of the leaf is simple, but may be lobed to pinnatisect. The margin of the leaves may be entire or toothed. The inflorescences are flowerheads comparable to those in the sunflower family. They are at the top of the stems or opposite leaves, and may have a flower stem or be seated, while each flowerhead may be on its own or in a cyme. Each individual flowerhead is surrounded by an involucre, consisting of one or two rows of bracts that are ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as Homoplasy, homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. [Source for pronunciation.] It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthesis, C4 photosynthetic plants, and Xenarthra#Evolutionary relationships, edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major re ...

Asterales Genera
Asterales ( ) is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the '' Lobelia deckenii'', the giant lobelia, and '' Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharid ...
