Vicoa is a genus of flowering plants belonging to elecampane tribe within the Asteraceae (sunflower family). [1] It is found in parts of Africa and stretching across Asia to Indochina. It was described by Alexandre Henri Gabriel de Cassini (Cass.) in 1829, but the genus was later absorbed into the Pentanema genus (also within the Asteraceae family). Until molecular analysis in 2018, determined it was a separate genus.
They are annual or perennial herbs, [2] with simple (undivided or unsegmented), [3] or entire (not divided) leaves. [2] The leaves are arranged alternate (at different levels along the stem), [2] [3] with pinnately veining (lateral veins are arranged either side of the main vein) and they are mostly amplexicaule (the base is dilated and clasping the stem) at the base. [2] They have flowers which have solitary, [2] radiate heads (ray floret surrounding disc florets), [2] [3] which are either axillary (beside a leaf joint) or leaf opposed. [2] They have a peduncle (flower stalk), [2] and involucral bracts which are inbricate (overlapping) in several rows. [3] The achenes (one-seeded indehiscent fruit) are subterete (partially circular in cross-section) with a pappus (a tuft or ring of hairs or scales borne above the ovary) of unequal bristles. [3]
There are about 14 accepted species; [1]
Some species are still to be accepted, such as Vicoa gokhalei from India. [4]
The genus name of Vicoa is in honour of Giambattista Vico (1668–1744), an Italian philosopher, rhetorician, historian, and jurist during the Italian Enlightenment. [5] It was first described and published in Ann. Sci. Nat. (Paris) Vol.17 on page 418 in 1829. [1]
It was then absorbed into the genus of Pentanema , until in 2018, the Vicoa genus was re-established due to molecular analysis of the Pentanema genus. [6]
It is native to parts of Africa and Asia. From the island of Cape Verde, (Macaronesia), then the African countries of; Angola, Benin, Burkina Faso, Central African Republic, Chad, Eritrea, Ethiopia, Guinea-Bissau, Ivory Coast, Malawi, Mali, Mauritania, Mozambique, Senegal, Somalia, Sudan, Tanzania, Togo, Uganda, Zambia and Zimbabwe. Parts of Western Asia; Afghanistan and Iran. Central Asia; Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. China; south-central and southeast China and Tibet. Indian subcontinent; East Himalaya, India, Nepal, Pakistan, Sri Lanka and West Himalaya. Lastly, parts of Indochina; Myanmar, Thailand and Vietnam. [1]
Some species such as Vicoa indica have used in folk medicine, in the Himalayas. [2] [7] [8] The roots were used to treat kidney troubles and the leaves were used for stomach problems. [9]
The family Asteraceae, with the original name Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown.
Meliaceae, the mahogany family, is a flowering plant family of mostly trees and shrubs in the order Sapindales.
Artemisia is a large, diverse genus of plants belonging to the daisy family Asteraceae, with between 200 and 400 species. Common names for various species in the genus include mugwort, wormwood, and sagebrush.
Pallenis is a small genus of flowering plants in the tribe Inuleae within the family Asteraceae. The name is derived from palea (chaff), referring to the chaffy receptacle.
Gerbera L. is a genus of plants in the Asteraceae (Compositae) family. The first scientific description of a Gerbera was made by J. D. Hooker in Curtis's Botanical Magazine in 1889 when he described Gerbera jamesonii, a South African species also known as Transvaal daisy or Barberton daisy. Gerbera is also commonly known as the African daisy.

Inula is a genus of about 80 species of flowering plants in the family Asteraceae, native to Europe, Asia and Africa.
Acmella is a genus of plants in the family Asteraceae, described as a genus in 1807. It is native to the Americas and has been introduced to Asia, Africa, the Pacific islands, and Australia.
Cotula is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds.
Pluchea is a genus of flowering plants in the tribe Inuleae within the family Asteraceae. Members of this genus might be known as camphorweeds, plucheas, or less uniquely fleabanes. Some, such as P. carolinensis and P. odorata, are called sourbushes. There are plants of many forms, from annual and perennial herbs to shrubs and trees, and there is variation in the morphology of leaves, flowers, and fruits.
Erechtites is a genus of flowering plants in the daisy family known commonly as fireweeds or burnweeds. They are native to the Americas and Australia, but some species are widely distributed weeds.
Anthemideae is a tribe of flowering plants in the family, Asteraceae, and the subfamily Asteroideae. They are distributed worldwide with concentrations in central Asia, the Mediterranean Basin, and southern Africa. Most species of plant known as chamomile belong to genera of this tribe.
Epaltes is a genus of flowering plants in the daisy family. They are distributed in Australia, the Americas, Asia, and Africa.
Gymnarrhena is a deviant genus of plants in the family Asteraceae, with only one known species, Gymnarrhena micrantha. It is native to North Africa and the Middle East, as far east as Balochistan. Together with the very different Cavea tanguensis it constitutes the tribe Gymnarrheneae, and in the subfamily Gymnarrhenoideae.
Pentanema is a genus of Asian and African plants in the tribe Inuleae within the family Asteraceae.
Cavea is a low perennial herbaceous plant that is assigned to the family Asteraceae. Cavea tanguensis is currently the only species assigned to this genus. It has a basal rosette of entire, slightly leathery leaves, and stems of 5–25 cm high, topped by bowl-shaped flower heads with many slender florets with long pappus and purplish corollas. The vernacular name in Chinese is 葶菊. It grows high in the mountains of China (Sichuan), Tibet, India (Sikkim), and Bhutan, and flowers in July and August.
