Verticordia sect. Infuscata 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 shrubs with greyish foliage, unusual flowers and an odour of mice. The floral cup has a tuft of hairs around its base, dull purple or cream-coloured flowers with divided sepals and petals with a transparent margin. [1] When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. [2] [3] The name Infuscata is derived from the Latin word fusca meaning "dark" or "dusky" [4] referring to the dullish colour of plants in this section. [1]

The type species for this section is Verticordia oxylepis and the other species is V. longistylis . [1]

Verticordia sect. Pennuligera is one of six sections in the subgenus Eperephes. It includes sixteen shrub species in the genus Verticordia. Plants in this section range from small and spreading to large shrubs and have been referred to as "lettuce-leaved" or "round-leaved". The flowers are relatively large, with their sepals having feathered lobes and ear-like appendages on a stalk so that the appendages cover the floral cup. The petals are oval to egg-shaped or round and are usually fringed.

Verticordia subg. Verticordia is a botanical name for a grouping of similar plant species in the genus Verticordia. This subgenus contains eleven sections, classifying thirty six species, of Alex George's infrageneric arrangement. A number of anatomical features differentiate the contained species from the other two subgenera.

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 sect. Tropica is one of six sections in the subgenus Eperephes. It includes three species of plants in the genus Verticordia. Plants in this section occur are the only verticordias to occur in tropical areas of Western Australia and the Northern Territory, including the Kimberley and Kakadu National Park and they have the ability to regrow from a lignotuber after fire. They have leaves which vary in size from tiny and pressed against the stem to long and curved but are always linear in shape. The flowers have fringed petals and lobed sepals with small, ear-like appendages and the style has a narrow band of hairs near its tip.

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. 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. Jugata is one of seven sections in the subgenus Chrysoma. It includes seven species of plants in the genus Verticordia. Plants in this section are mostly bushy shrubs to 1.0 m (3 ft) tall with bright yellow flowers which in some species turn red as they age. They have sepals with fringed lobes, petals which have lobes arranged like the fingers of a hand and bracteoles which are joined together and remain attached to the flower after it opens. When Alex George reviewed the genus in 1991, he described the section and gave it the name Jugata. The name Jugata is from the Latin word jugis meaning "yoked together" referring to the arrangement of the bracteoles in these species.

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.

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. Intricata is one of eleven sections in the subgenus Verticordia. It includes three species of plants in the genus Verticordia. Plants in this section are usually bushy shrubs, sometimes cauliflower-like, with greyish leaves and fluffy or woolly pink to red, sometimes white flowers. The sepals have intricately branched lobes and hairy appendages and the stamens and staminodes are joined in a ring structure. When Alex George reviewed the genus in 1991 he formally described this section, publishing the description in the journal Nuytsia. The name Intricata is from the Latin word intricatus meaning "entangled" or "complicated" referring to the intricately divided sepals.

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.

Verticordia sect. Jamiesoniana is one of six sections in the subgenus Eperephes. It includes the single species Verticordia jamiesonii. Plants in this section have tiny, yellowish leaves and white flowers that turn pink as they age and have stamens and staminodes with slightly thickened hairs.
