Fasciation
Fasciation (pronounced , from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested (or "cristate"), or elaborately contorted tissue. Fasciation may also cause plant parts to increase in weight and volume in some instances. The phenomenon may occur in the stem, root, fruit, or flower head. Some plants are grown and prized aesthetically for their development of fasciation. Any occurrence of fasciation has several possible causes, including hormonal, genetic, bacterial, fungal, viral and environmental causes. Cause Fasciation can be caused by hormonal imbalances in the meristematic cells of plants, which are cells where growth can occur. Fa ...

Celosia
''Celosia'' ( ) is a small genus of edible and ornamental plants in the amaranth family, Amaranthaceae. The generic name is derived from the Ancient Greek word (), meaning "burning", and refers to the flame-like flower heads. Species are commonly known as woolflowers, or, if the flower heads are crested by fasciation, cockscombs. The plants are well known in East Africa's highlands and are used under their Swahili name, mfungu. Uses As a garden plant The plant is an annual. Seed production in these species can be very high, 200–700 kg per hectare. One ounce of seed may contain up to 43,000 seeds. One thousand seeds can weigh 1.0–1.2 grams. Depending upon the location and fertility of the soil, blossoms can last 8–10 weeks. '' C. argentea'' and '' C. cristata'' are common garden ornamental plants. As food ''Celosia argentea'' var. ''argentea'' or Lagos spinach (a.k.a. quail grass, soko, celosia, feather cockscomb) is a broadleaf annual leaf vegetable. It grows w ...

Digitalis
''Digitalis'' ( or ) is a genus of about 20 species of herbaceous perennial plants, shrubs, and biennials, commonly called foxgloves. ''Digitalis'' is native to Europe, western Asia, and northwestern Africa. The flowers are tubular in shape, produced on a tall spike, and vary in colour with species, from purple to pink, white, and yellow. The scientific name means "finger". The genus was traditionally placed in the figwort family, Scrophulariaceae, but phylogenetic research led taxonomists to move it to the Veronicaceae in 2001. More recent phylogenetic work has placed it in the much enlarged family Plantaginaceae. The best-known species is the common foxglove, ''Digitalis purpurea''. This biennial is often grown as an ornamental plant due to its vivid flowers which range in colour from various purple tints through pink and purely white. The flowers can also possess various marks and spottings. Other garden-worthy species include ''D. ferruginea'', ''D. grandiflora'', ''D. ...

Delphinium
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family (biology), family Ranunculaceae, native plant, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like p ...

Cycas
''Cycas'' is a genus of plants belonging to a very ancient lineage, the Cycadophyta, which are not closely related to palms, ferns, trees or any other modern group of plants. They are evergreen perennials which achieved their maximum diversity in the Jurassic and Cretaceous periods, when they were distributed almost worldwide. At the end of the Cretaceous, when the non-avian dinosaurs became extinct, so did most of the cycas in the Northern Hemisphere. ''Cycas'' is the type genus and the only extant genus recognised in the family Cycadaceae. About 113 species are accepted. ''Cycas circinalis'', a species endemic to India, was the first cycad species to be described in western literature, and was the type of the generic name, ''Cycas''. The best-known ''Cycas'' species is ''Cycas revoluta''. Range The genus is native to the Old World, with the species concentrated around the equatorial regions - eastern and southeastern Asia including the Philippines with 10 species (9 of which ar ...

Cannabis
''Cannabis'' () is a genus of flowering plants in the family Cannabaceae. The number of species within the genus is disputed. Three species may be recognized: ''Cannabis sativa'', '' C. indica'', and '' C. ruderalis''. Alternatively, ''C. ruderalis'' may be included within ''C. sativa'', all three may be treated as subspecies of ''C. sativa'', or ''C. sativa'' may be accepted as a single undivided species. The genus is widely accepted as being indigenous to and originating from Asia. The plant is also known as hemp, although this term is often used to refer only to varieties of ''Cannabis'' cultivated for non-drug use. Cannabis has long been used for hemp fibre, hemp seeds and their oils, hemp leaves for use as vegetables and as juice, medicinal purposes, and as a recreational drug. Industrial hemp products are made from cannabis plants selected to produce an abundance of fibre. Various cannabis strains have been bred, often selectively to pro ...

Acanthosicyos
''Acanthosicyos'' is a genus of thorny shrubs of the botanical family Cucurbitaceae, subfamily Cucurbitoideae. The genus name derives from the Greek words "''akantha''" for thorn and "''sykios''" for cucumber or gourd. Species Endemic to the Namib Desert in Africa, this genus is represented by two known species including ''Acanthosicyos horridus'', the nara melon, an important food plant in its native range. Both species are dioecious Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants).

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
