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.

<i>Verticordia</i> Genus of flowering plants

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 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.

The name Jugata is from the Latin word jugis meaning "yoked together" referring to the arrangement of the bracteoles in these species.

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.
