Silphium asteriscus var. trifoliatum Flora of North America This species is considered to be a variety of Silphium asteriscus by some authors. It can be distinguished by its smooth stems and leaves that are often in whorls of three. In contrast, S. asteriscus has scabrous to hispid stems and leaves, which are opposite or alternate.

In addition, S. trifoliatum has eglandular pales (the bracts in the flower heads), while the pales of S. asteriscus are often glandular. There remains much disagreement about the best taxonomic treatment of the S. asteriscus complex.

Asteriscus aquaticus is a species of flowering plant. The flower is part of the so-called "Asteriscus alliance".. Formally known by its basionym, Bupthalmum aqualicum, when it was originally described in 1753 as a species of the Buphthalmum genus. Its original name meant sweet-scented ox eye.

This developed, in later species, into the lung and (later) the swim bladder, used to keep the fish at neutral buoyancy. Acanthodians share with Actinopterygii the characteristic of three otoliths, the sagitta in the sacculus, the asteriscus in the lagena, and the lapillus in the utriculus. In dipnoans there are only two otoliths and in Latimeria there is only one. However, most of the above synapomorphies can ultimately be found in several chondrychthyian groups.

Over 80 vascular plant taxa are reported to be endemic to Cape Verde; these include Tornabenea, Aeonium gorgoneum, Campanula bravensis (bellflower), Asteriscus smithii (Nauplius smithii), Artemisia gorgonum (sagebrush), Sideroxylon marginata, Lotus jacobaeus, Lavandula rotundifolia, Sarcostemma daltonii, Euphorbia tuckeyana, Polycarpaea gayi and Erysimum caboverdeanum (wallflower).Several trees are indigenous such as the blue-green flat-topped dragon tree Dracaena draco, Tamarix senegalensis, Phoenix atlantica (tamateira), in the lagoons and deserts of Boavista, the ironwood tree and a species of fig tree and Faidherbia albida (formerly known as Acacia albida and locally called simply "acácia"). As a result of extensive tree planting since 1975, there are pine trees, oaks and sweet chestnuts on the cool peaks of Santo Antao, eucalyptus on the heights of Fogo, and forests of acacia on Maio.

The system was further refined by his student Aristophanes of Byzantium, who first introduced the asterisk and used a symbol resembling a for an obelus; and finally by Aristophanes' student, in turn, Aristarchus, from whom they earned the name of "Aristarchian symbols". While the asterisk (asteriscus) was used for corrective additions, the obelus was used for corrective deletions of invalid reconstructions. It was used when non-attested words are reconstructed for the sake of argument only, implying that the author did not believe such a word or word form had ever existed. Some scholars used the obelus and various other critical symbols, in conjunction with a second symbol known as the metobelos ("end of obelus"), variously represented as two vertically arranged dots, a -like symbol, a mallet-like symbol, or a diagonal slash (with or without one or two dots).
