Cistus is a genus of flowering plants in the rockrose family Cistaceae, containing about 20 species. They are perennial shrubs found on dry or rocky soils throughout the Mediterranean region, from Morocco and Portugal through to the Middle East, and also on the Canary Islands.
Leucospermum is a genus of evergreen upright, sometimes creeping shrubs that is assigned to the Proteaceae, with currently forty-eight known species. Almost all species are easily recognised as Leucospermum because of the long protruding styles with a thickened pollen-presenter, which jointly give the flower head the appearance of a pincushion, its common name. Pincushions can be found in South Africa, Swaziland, Zimbabwe and Mozambique.
In zoological nomenclature, author citation refers to listing the person who first makes a scientific name of a taxon available. This is done in a scientific publication while fulfilling the formal requirements under the International Code of Zoological Nomenclature, hereinafter termed "the Code". According to the Code, "the name of the author does not form part of the name of a taxon and its citation is optional, although customary and often advisable", however Recommendation 51A suggests: "The original author and date of a name should be cited at least once in each work dealing with the taxon denoted by that name. This is especially important in distinguishing between homonyms and in identifying species-group names which are not in their original combinations". For the purpose of information retrieval, the author citation and year appended to the scientific name, e.g. genus-species-author-year, genus-author-year, family-author-year, etc., is often considered a "de facto" unique identifier, although for a number of reasons discussed below, this usage may often be imperfect.
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the International Code of Nomenclature for algae, fungi, and plants (ICN). In cases where a species is no longer in its original generic placement, both the authority for the original genus placement and that for the new combination are given.
Ipomoea violacea is a perennial species of Ipomoea that occurs throughout the world with the exception of the European continent. It is most commonly called beach moonflower or sea moonflower as the flowers open at night.
In biological nomenclature, a nomen novum, new replacement name is a technical term. It indicates a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons ; it does not apply when a name is changed for taxonomic reasons. It is frequently abbreviated, e.g.nomen nov., nom. nov..
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name to the Norway spruce, which he called Pinus abies. This name is no longer in use: it is now a synonym of the current scientific name, Picea abies. In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination, rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refer to a taxon at that rank - for example, the name Papilio prorsaLinnaeus, 1758 is a junior synonym of Papilio levanaLinnaeus, 1758, being names for different seasonal forms of the species now referred to as Araschnia levana(Linnaeus, 1758), the map butterfly. However, Araschnia levana is not a synonym of Papilio levana in the taxonomic sense employed by the Zoological code.
Sensu is a Latin word meaning "in the sense of". It is used in a number of fields including biology, geology, linguistics, semiotics, and law. Commonly it refers to how strictly or loosely an expression is used in describing any particular concept, but it also appears in expressions that indicate the convention or context of the usage.
Leucospermum cordifolium is an upright, evergreen shrub of up to 1½ m (5 ft) high from the Proteaceae. The flower heads are globe-shape with a flattened top, 10–12 cm (3.9–4.7 in) in diameter, and are carried individually or with two or three together mostly at a right angle to its branch. The perianth is 3–3½ cm long, yellow, orange or crimson in color. From each flower emerges a 4½–6 cm (1.8–2.4 in) long style sticking out horizontally but curving upwards near the obliquely, shell-shaped, thicker pollen presenter. This gives each head the appearance of a pincushion. Its common name is ornamental pincushion in English and bobbejaanklou in Afrikaans. It flowers between the middle of July and the end of November. It naturally occurs near the south coast of the Western Cape province of South Africa. Varieties and hybrids of this species are used as cut flower and garden plant.
Monopis laevigella, the skin moth, is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the nominate subfamily Tineinae. It is the type species of the genus Monopis and its junior objective synonym Hyalospila. As with the common clothes moth, earlier authors frequently misapplied the name Tinea vestianella to the present species.

Cistus × incanusL. is a hybrid between Cistus albidus and Cistus crispus. The name "Cistus incanus" has been used by other authors in a different sense, for Cistus creticus. The English name hoary rock-rose may refer to this species, among others.
Cistus clusii is a shrubby species of flowering plant in the family Cistaceae, with white flowers, native to south west and south central Europe and north Africa. It has been wrongly called Cistus libanotis by many authors.
Cistus inflatus is a shrubby species of flowering plant in the family Cistaceae, often known as Cistus psilosepalus, although this name is a synonym of the hybrid Cistus × laxus. It has white flowers.
Cistus libanotis is a shrubby species of flowering plant in the family Cistaceae, with white flowers. It has been confused with Cistus clusii, which it resembles, resulting in some uncertainty in its distribution. It is endemic to the Iberian Peninsula.
Leucospermum bolusii is a shrub native to South Africa. It grows to 1.5 m in height, and has nearly hairless leaves with a single apical tooth. The leaves are oval shaped and range from 25–45 mm (0.98–1.77 in) in length. The flower heads are about 2 cm in diameter, slightly flattened globe shaped, are set on a stalk of about 1 cm and crowded with up to eight together at the tip of the branches. They each contain 50–100 small, sweetly scented creamy white flowers, that later turn light pink. Flowering takes place between September and December. It is called Gordon's Bay pincushion in English and witluisiesbos in Afrikaans.
Leucospermum lineare is an evergreen shrub with linear leaves and is assigned to the Proteaceae. There are two distinct forms that have not been formally recognized as separate taxa. There is an upright form with orange flower heads of up to 2 m (6.6 ft) high, and a sprawling form of 2–3 m (6.6–9.8 ft) in diameter with yellow flower heads. Its common name is needle-leaf pincushion, or narrow-leaf pincushion, in English and smalblaarspeldekussing in Afrikaans. The orange-flowered form is called tangerine pincushion or assegaaibos pincushion. Flowering occurs in the first half of the southern hemisphere season, but peaks in September and October. It is an endemic species that can only be found in the southwest of the Western Cape province of South Africa.
Leucospermum truncatulum is a slender, upright, evergreen, hardly branching shrub of up to 2 m (6 ft) high, with felty inverted egg-shaped to oval, leaves with entire margins of 1–2½ cm (0.4–1.0 in) long and ½–1 cm (0.2–0.4 in) wide. It has small globe-shaped, at first yellow, later pinkish flower heads of 1½–2 cm (0.6-0.8 in) in diameter, without a stalk, usually crowded with two to eight together near the end of the stems. It is known as oval-leaf pincushion in English, and patrysbos or kleinkopspeldekussing in Afrikaans. It is an endemic species of the south of the Western Cape province of South Africa, and flowers between August and December.
Leucospermum cordatum is an evergreen, creeping shrublet of about 20 cm (8 in) high from the family Proteaceae. It has pale cream flower heads, from which pink flushed styles emerge, the whole reminiscent of a pincushion. Its common name is heart-leaf pincushion in English. It flowers between July and December but the peak of the flowering period is from September to November. It is an endemic species, that is only known from two locations close to each other in the Western Cape province of South Africa.
