In biology, a subgenus is a taxonomic rank directly below genus.
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 sect. Verticordia is one of eleven sections in the subgenus Verticordia. It includes eight species of plants in the genus Verticordia. Plants in this section are open to bushy shrubs up to 1 m (3 ft) tall with needle-like leaves, feather-like sepals and anthers opening by slanting pores. When Johannes Conrad Schauer described other subgenera in Verticordia, subgenus Verticordia became an autonym after Augustin de Candolle who described the genus in 1828. When Alex George reviewed the genus in 1991, he took the name of this section from that of the subgenus.
Verticordia subg. Chrysoma is a botanical name for a grouping of similar plant species in the genus Verticordia.
Verticordia sect. Chrysoma is one of seven sections in the subgenus Chrysoma. It includes four species of plants in the genus Verticordia. Plants in this section are small shrubs with small, bright yellow flowers which usually turn red as they age. They have sepals with fringed lobes and petals which have lobes arranged like the fingers of a hand. The subgenus Chrysoma was originally described in 1843 by Johannes Conrad Schauer and the description was published in Monographia Myrtacearum Xerocarpicarum. When Alex George reviewed the genus in 1991, he took the name of this section from that of the subgenus.
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 2.0 m (7 ft) 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 occurring in the Northern Territory.
Verticordia verticordina is a flowering plant in the myrtle family, Myrtaceae and is endemic to a small area near the coast of the south-west of Western Australia. It is a small, low-growing shrub with crowded leaves and in spring, scattered pale greenish-cream and golden brown flowers. Its unusual flowers and fleshy leaves give the plant a superficial resemblance to a Darwinia.
Verticordia sect. Verticordella is one of six sections in the subgenus Eperephes. It includes eighteen species in the genus Verticordia. Plants in this section are often small, bushy shrubs with a single main stem and scented flowers. The leaves are linear, usually semi-circular in cross-section and have a hairy or irregularly toothed edge. The flowers are pink, sometimes red to purple, pale yellow or white. They have a floral cup with downward curving appendages, bracteoles which are shed when the flower opens, and sepals with fringed lobes. The petals have a fringed or toothed margin and a curved style that is hairy at the apex.
Verticordia sect. Elachoschista is one of eleven sections in the subgenus Verticordia. It includes a single species in the genus Verticordia. Plants in this section resemble those in section Infuscata except that the sepal lobes are not divided but may have an irregularly toothed edge. Plants in this section superficially resemble some of the smaller Darwinia species. The leaves are crowded and the flower are cream-coloured, turning greenish-brown as they age. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. The name Elachoschista is derived from the Ancient Greek words elachys meaning "little" and schizo meaning "cut" referring to the sepals which have almost smooth edges.
Verticordia sect. Chrysorhoe is a section that describes three shrub species in the genus Verticordia. The section is one of seven in the subgenus, Verticordia subg. Chrysoma. The three species in this section are inflexible, upright shrubs usually no taller than 2 m (7 ft). They have needle-like leaves and their flowers are arranged corymb-like, sometimes densely on the ends of the branches. The flowers are orange, gold-coloured or yellow and the petals have toothed margins, the anthers have a flattened, swollen appendage and the staminodes are narrow.
Verticordia sect. Cooloomia is a section that describes a single species in the flowering plant genus Verticordia. The section is one of seven in the subgenus, Verticordia subg. Chrysoma. The characteristics of this section includes leaves that differ in shape, depending on their position on the plant and very small sepals. In most other respects, the one plant in this section is similar to those in section Verticordia sect. Chrysoma.
Verticordia sect. Synandra is a section that describes a single species in the genus Verticordia. The section is one of seven in the subgenus, Verticordia subg. Chrysoma. The characteristics of this section includes having branches and flower stalks which are covered with stiff, bristly hairs, and stamens and staminodes which are joined at their base in a tube. The subspecies and varieties of the single species in this section all have bright green leaves and superficially resemble dwarf pine trees.
Verticordia sect. Unguiculata is one of seven sections in the subgenus Chrysoma. It includes three species of plants in the genus Verticordia. Plants in this section are rigid shrubs with a single main stem and are less than 1.0 m (3 ft) tall. They have yellow flowers arranged in corymb-like groups and the flowers turn red as they age. They have sepals with fringed lobes, petals which have lobes arranged like the fingers of a hand and anthers which have an appendage which looks like a pair of claws. When Alex George reviewed the genus in 1991, he described the section and gave it the name Unguiculata. The name Unguiculata is the diminutive form of the Latin word unguis meaning "little claw" or "little talon" referring to the anther appendage in these species.
Verticordia sect. Sigalantha is one of seven sections in the subgenus Chrysoma. It includes two species of plants in the genus Verticordia. Plants in this section are rigid shrubs with a single main stem and are up to 1.0 m (3 ft) tall. They have golden-yellow flowers with prominent shining petals. The flowers are arranged in corymb-like groups and become pale or grey as they age. The bracteoles fall off the flower as it opens. When Alex George reviewed the genus in 1991, he described the section and gave it the name Sigalantha. The name Sigalantha is derived from the Ancient Greek words sigaloeis meaning "shiny" and anthos meaning "flower" referring to the shiny petals of these species.
Verticordia sect. Penicillaris is one of eleven sections in the subgenus Verticordia. It includes two species of plants in the genus Verticordia. Plants in this section are small, rounded shrubs with tiny leaves and sticky flowers. Like those in section Micrantha, the plants often smell faintly of mice. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. The name Penicillaris is from the type species from this section.
Verticordia sect. Pilocosta is one of eleven sections in the subgenus Verticordia. It includes three species of plants in the genus Verticordia. Plants in this section are mostly small, bushy shrubs greyish, needle-like leaves and hairy, rather than feathery flowers. Plants in this section have a flower cup with 10 hairy ribs, fringed sepals and a style which is hairy and has a distinct cap. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. The name Pilocosta is from the Latin words pilus meaning "hair" and costa meaning "rib" referring to the hairy ribs on the floral cup.
Verticordia sect. Catocalypta is one of eleven sections in the subgenus Verticordia. It includes seven species of plants in the genus Verticordia. Plants in this section are small, bushy shrubs which grow to a height of up to 1 m (3 ft), have thick, fleshy, leaves which are triangular in cross-section. The flowers are arranged in open, corymb-like heads of relatively large flowers. Importantly, their sepals have down-turned, tufts of hair which surround the floral cup.
Verticordia sect. Platandra is one of eleven sections in the subgenus Verticordia. It includes two species of plants in the genus Verticordia. Plants in this section resemble V. pritzelii in section Catocalypta but differ in they do not have tufts of hair on their sepals. The anthers are flattened and the hairs on the style are forked. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia.
Verticordia sect. Recondita is one of eleven sections in the subgenus Verticordia. It includes a single species in the genus Verticordia. Plants in this section are inconspicuous shrubs with linear leaves which are triangular in cross-section, rather scattered flowers and staminodes tapering to a fine point. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. The name Recondita is derived from the Latin word reconditus meaning "concealed" or "hidden" referring to the small size and scattered flowers of plants in this section.
Verticordia sect. Integripetala is one of six sections in the subgenus Eperephes. It includes five species of plants in the genus Verticordia. Plants in this section are mostly small, bushy shrubs with needle-like leaves and dark red to pink or creamy-white flowers with their petals having smooth edges. Most species are confined to the wheatbelt. When Alex George reviewed the genus in 1991, he described the section and gave it the name Integripetala. The name Integripetala is from the Latin words integer meaning "whole", "entire" or "sound" and petalum meaning "petal" referring smooth or entire edges of the petals in these species.
