Verticordia Subg. Eperephes
''Verticordia'' subg. ''Eperephes'' is a botanical name for a grouping of similar plant species in the genus ''Verticordia''. This subgenus contains six sections, classifying forty four species, of Alex George's infrageneric arrangement. The subgeneric name is derived from the Greek word ''eperephes'', in reference to over-hanging parts at the hypanthium which differentiate the contained species from the other two subgenera. :''Verticordia'' subg. ''Eperephes'' ::Section ''Integripetala'' ::Section ''Tropica'' :::3 species, the type species for this section is '' Verticordia cunninghamii''.

Verticordia
:For the clam genus, see ''Verticordia'' (bivalve). ''Verticordia'' is a genus of more than 100 species of plants commonly known as featherflowers, in the myrtle family, Myrtaceae. They range in form from very small shrubs such as '' V. verticordina'' to trees like '' V. cunninghamii'', some spindly, others dense and bushy, but the majority are woody shrubs up to tall. The flowers are variously described as "feathery", "woolly" or "hairy" and are found in most colours except blue. They often appear to be in rounded groups or spikes but in fact are always single, each flower borne on a separate stalk in a leaf axil. Each flower has five sepals and five petals all of a similar size with the sepals often having feathery or hairy lobes. There are usually ten stamens alternating with variously shaped staminodes. The style is simple, usually not extending beyond the petals and often has hairs near the tip. All but two species are found in Southwest Australia, the other two occur ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Alex George (botanist)
Alexander Segger George (born 4 April 1939) is a Western Australian botanist. He is the authority on the plant genera ''Banksia'' and ''Dryandra''. The "bizarre" Restionaceae genus '' Alexgeorgea'' was named in his honour in 1976. Early life Alex Segger George was born in Western Australia on 4 April 1939. Career George joined the Western Australian Herbarium as a laboratory assistant at the age of twenty in 1959. He worked under Charles Gardner for a year before the latter's retirement, and partly credits him with rekindling an interest in banksias. In 1963 he graduated with a Bachelor of Arts from the University of Western Australia, and the following year added a botany major. Continuing at the Western Australian Herbarium as a botanist, in 1968 he was seconded as Australian Botanical Liaison Officer at the Royal Botanic Gardens in London. George also has an interest in history, especially historical biography of naturalists in Western Australia. He has published a number ...

Hypanthium
In angiosperms, a hypanthium or floral cup is a structure where basal portions of the calyx, the corolla, and the stamens form a cup-shaped tube. It is sometimes called a floral tube, a term that is also used for corolla tube and calyx tube. It often contains the nectaries of the plant. It is present in many plant families, although varies in structural dimensions and appearance. This differentiation between the hypanthium in particular species is useful for identification. Some geometric forms are obconic shapes as in toyon, whereas some are saucer-shaped as in '' Mitella caulescens''. Its presence is diagnostic of many families, including the Rosaceae, Grossulariaceae, and Fabaceae. In some cases, it can be so deep, with such a narrow top, that the flower can appear to have an inferior ovary - the ovary is below the other attached floral parts. The hypanthium is known by different common names in differing species. In the eucalypts, it is referred to as the ''gum nut''; ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
