Black pepper is a flowering vine in the family Piperaceae, cultivated for its fruit, which is usually dried and used as a spice and seasoning, known as a peppercorn. When fresh and fully mature, it is about 5 mm (0.20 in) in diameter and dark red, and contains a single seed, like all drupes. Peppercorns and the ground pepper derived from them may be described simply as pepper, or more precisely as black pepper, green pepper, and white pepper.
Asplenium is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider Hymenasplenium separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is Asplenium marinum.
Acer nigrum is a species of maple closely related to A. saccharum, and treated as a subspecies of it by some authors, as Acer saccharum subsp. nigrum.
The setaceous Hebrew character is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found in the Palearctic ecozone. It is a common species throughout Europe and North Asia and Central Asia, South Asia, China, Japan and Korea. It is also found in North America, from coast to coast across Canada and the northern United States to western Alaska. It occurs in the Rocky Mountains from Montana to southern Arizona and New Mexico. In the east, it ranges from Maine to North Carolina. It has recently been recorded from Tennessee.
Solanum nigrum is a species in the genus Solanum, native to Eurasia and introduced in the Americas, Australasia, and South Africa. It is also known as black nightshade. Parts of this plant can be toxic to livestock and humans. Nonetheless, ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine. A tendency exists in literature to incorrectly refer to many of the other "black nightshade" species as "Solanum nigrum".
Centroscyllium is a genus of big-eyed, deepwater dogfishes with no anal fin, a grey or black-brown body, and dorsal spines, with the second one being much larger than the first. Seven extant species are described.
The combtooth dogfish is a little-known, deepwater dogfish shark.
Allium nigrum, common name black garlic, broad-leaved leek, or broadleaf garlic, is a Middle Eastern species of wild onion. It lacks the onion or garlic scent shared by most of the other species in the group. The species is native to Turkey, Cyprus, Syria, Lebanon, and Israel but cultivated as an ornamental in many other places. It has become naturalized in some regions, including parts of the United States.
Empetrum nigrum, crowberry, black crowberry, or, in western Alaska, blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the northern hemisphere. It is also native in the Falkland Islands. It is usually dioecious, but there is a bisexual tetraploid subspecies, Empetrum nigrum ssp. hermaphroditum, that occurs in more northerly locations and at higher altitude.
Verbascum nigrum the black mullein or dark mullein, is a species of biennial or short-lived perennial herbaceous plants in the genus Verbascum (mullein), native to dry open sites in Europe and the Mediterranean region. It grows to 0.5–1.5 m (1.6–4.9 ft).
Arctornis l-nigrum, the black V moth, is a moth of the family Erebidae. The species was described by Johannes Peter Müller in 1764. It is found in the Palearctic realm and Asia.
Solamargine is a poisonous chemical compound that occurs in plants of the Solanaceae family, such as potatoes, tomatoes, and eggplants. It has been also isolated from Solanum nigrum fungal endophyte Aspergillus flavus. It is a glycoalkaloid derived from the steroidal alkaloid solasodine.
Asplenium adiantum-nigrum is a common species of fern known by the common name black spleenwort. It is found mostly in Africa, Europe, and Eurasia, but is also native to a few locales in Mexico and the United States.
Asplenium onopteris is known as the Irish spleenwort or western black spleenwort. It is difficult to identify compared with the black spleenwort, Asplenium adiantum-nigrum. The main difference is that A. onopteris is diploid and is one of the two parents of the tetraploid A. adiantum-nigrum. Armed with a microscope, the most consistent observable difference between A. onopteris and A. adiantum-nigrum is that A. onopteris spores have a mean diameter of 28 μm and are almost all smaller than 31 μm, whereas those of A. adiantum-nigrum have a mean diameter of 34 μm and are almost all larger than 31 μm. The leaflets of typical A. onopteris are narrower in relation to their length than those of typical A. adiantum-nigrum, but this is not a reliable means of identification.
Epicoccum nigrum is a species of fungus, in the phylum Ascomycota. A plant pathogen and endophyte, it is a widespread fungus which produces coloured pigments that can be used as antifungal agents against other pathogenic fungi. The fluorescent stain, epicocconone is extracted from it.
Dorcaschema alternatum is a species of beetle in the family Cerambycidae. It was described by Say in 1824, originally under the genus Saperda. It is known from the United States. It feeds off of Morus celtidifolia.
Dorcaschema cinereum is a species of beetle in the family Cerambycidae. It was described by Olivier in 1795, originally under the genus Saperda. It is known from the United States.
Dorcaschema succineum is an extinct species of beetle in the family Cerambycidae. It was described by Zang in 1905. It existed during the Upper Eocene, and has been discovered within Baltic amber.
Dorcaschema wildii, the mulberry borer, is a species of beetle in the family Cerambycidae. It was described by Uhler in 1855. It is known from the United States.
Guineesine is an alkaloid isolated from long pepper and black pepper.
