Context paragraphs:
Dracaena braunii: Dracaena braunii is a species of the genus "Dracaena".  It is also known as "Dracaena sanderiana", after the German–English gardener Henry Frederick Conrad Sander (1847–1920).  Common names include Sander's dracaena, ribbon dracaena, lucky bamboo, curly bamboo, Chinese water bamboo, friendship bamboo, Goddess of Mercy plant, Belgian evergreen, and ribbon plant.  Although the word "bamboo" occurs in several of this plant's common names, "D. braunii" is of an entirely different taxonomic order from true bamboos. Despite several of its common names that suggest it is from China or Belgium, it is a native African species.

Caulophyllum: Caulophyllum is a small genus of perennial herbs in the family Berberidaceae.  It is native to eastern Asia and eastern North America.  These plants are distinctive spring wildflowers, which grow in moist, rich woodland, it is known for its large triple-compound leaf, and large blue, berry-like fruits. Unlike many spring wildflowers, it is not an ephemeral plant and persists throughout much of the summer.  Common names for plants in this genus include Blue Cohosh, Squaw Root, and Papoose Root.  As hinted at by its common names, this plant is well known as an alternative medicine for inducing childbirth and menstrual flow; it is also considered a poisonous plant.

Salicornia: Salicornia is a genus of succulent, halophyte (salt tolerant) flowering plants in the family Amaranthaceae that grow in salt marshes, on beaches, and among mangroves. "Salicornia" species are native to North America, Europe, South Africa, and South Asia.  Common names for the genus include glasswort, pickleweed, picklegrass, and marsh samphire; these common names are also used for some species not in "Salicornia".  The main European species is often eaten, called marsh samphire in Britain, and the main North American species is occasionally sold in grocery stores or appears on restaurant menus, usually as <nowiki>'</nowiki>sea beans<nowiki>'</nowiki> or samphire greens or sea asparagus .

List of English animal nouns: The following is a list of English animal nouns, (the common names of kinds of animals).  This list includes the common names used for the animal in general; names for the male animal and the female animal where such names exist; the name used for the young or juveniles of the animal; the common name given for the sound the animal makes, if any; the group noun where applicable; and the name of both the natural shelter and (if applicable) an artificial shelter for the animals.

List of common names of lichen genera: This is a list of common names of lichen genera.  When a common name for a lichen genus is the same as the scientific name for that genus, it is not included in the following list.  This list only includes genera common names that are widely used, as indicated by the common name either appearing in a peer reviewed scientific publication or in a scientifically reliable reference source.

List of plants by common name: This is a list of plants organized by their common names. However, the common names of plants often vary from region to region, which is why most plant encyclopedias refer to plants using their scientific names, in other words using binomials or "Latin" names.

Psilotum: Psilotum is a genus of fern-like vascular plants, commonly known as whisk ferns.  It is one of two genera in the family Psilotaceae, the other being "Tmesipteris".  Plants in these two genera were once thought to be descended from the earliest surviving vascular plants, but more recent phylogenies place them as basal ferns, as a sister group to Ophioglossales.  They lack true roots and leaves, the stems being the organs containing conducting tissue.  There are only two species in "Psilotum" and a hybrid between the two.  They differ from those in "Tmesipteris" in having stems with many branches and a synangium with three lobes rather than two.

Thonningia: Thonningia is a monotypic genus of flowering plants in the family Balanophoraceae containing the single species Thonningia sanguinea.  It is distributed throughout much of southern and western Africa, particularly the tropical regions.  Common names for the plant include ground pineapple.  A familiar plant to humans, it has an extremely long list of common names in many African languages.  Many names are inspired by the resemblance of the plant's inflorescence to a pineapple or palm tree.  Some of the names can be translated as pineapple of the bush (from Anyi), duiker's kolanut (from Igala), and crown of the ground (from Yoruba).

Conophytum: Conophytum is a genus of South African and Namibian succulent plants that belong to the Aizoaceae family.  The name is derived from the Latin “conus” (cone) and Greek “phytum” (plant).  The plants are also known as knopies (buttons), waterblasies (water blisters), sphaeroids, conos, cone plants, dumplings, or button plants.

List of the most common surnames in Germany: Although "Müller" is the most common name in German-speaking countries, in some areas other surnames are more frequent than Müller.  The common names Schmidt and Schmitz lead in the central German-speaking and eastern Low German-speaking areas.  "Meyer" is particularly common in the Low German-speaking regions, especially in Lower Saxony (where it is more common than Müller).  "Bauer" leads in eastern Upper German-speaking Bavaria.  Rarer names tend to accumulate in the north and south.  "Huber" is common in southern Bavaria and is, with the exception of Munich, the most frequent name in that area.  The Patronymic surnames Jansen/Janssen, Hansen, and Petersen are the most common names in the far north (Lower Saxony and Schleswig-Holstein).
