Hannoa is a genus of plant in the family Simaroubaceae. Found in tropical parts of Africa.
The genus consists of trees, shrubs or shrublets. They have leaves that are not crowded at the ends of the branches, imparipinnate. With leaflets opposite or alternate (spaced), sometimes with scattered thickenings or depressions. The flowers are unisexual or bisexual. The inflorescences are axillary or terminal or paniculate. The carpels are 1-ovulate. They have 6–9 petals, which are imbricate (overlapping). The ovary in bisexual flowers is similar but much larger. The calyx is irregularly and sometimes shallowly 2–4-lobed. They generally have a vestigial ovary in the male flowers which is sunk in the disk, of 5 carpels with very short connate styles and 5 stigmas. They normally have 10 stamens but can have up to 12–14, with 5 opposing the petals and somewhat shorter. The flower disk is thick and fleshy, ± 10-ribbed or -lobed. The fruit (or seed capsule) consists of 1–3 disruptive mericarps. [1]
The genus was first published in London J. Bot. vol.5 on page 566 in 1846. [2]
Plants of the World Online lists 2 accepted species; [2]
It is an accepted genus by GRIN (United States Department of Agriculture and the Agricultural Research Service), but they only list 1 species, Hannoa undulata(Guill. & Perr.) Planch. [3]
While World Flora Online lists it as a synonym of Quassia L. [4]
As listed by Plants of the World; [2]
Hannoa klaineana and Hannoa chlorantha are used in traditional medicine of Central African countries against fevers and malaria. [5] [6]
Quassia is a plant genus in the family Simaroubaceae. Its size is disputed; some botanists treat it as consisting of only one species, Quassia amara from tropical South America, while others treat it in a wide circumscription as a pantropical genus containing up to 40 species of trees and shrubs.
Plant reproductive morphology is the study of the physical form and structure of those parts of plants directly or indirectly concerned with sexual reproduction.
The Simaroubaceae are a small, mostly tropical, family in the order Sapindales. In recent decades, it has been subject to much taxonomic debate, with several small families being split off. A molecular phylogeny of the family was published in 2007, greatly clarifying relationships within the family. Together with chemical characteristics such as the occurrence of petroselinic acid in Picrasma, in contrast to other members of the family such as Ailanthus, this indicates the existence of a subgroup in the family with Picrasma, Holacantha, and Castela.
Boswellia is a genus of trees in the order Sapindales, known for its fragrant resin. The biblical incense frankincense is an extract from the resin of the tree Boswellia sacra, and is now produced also from B. frereana.
Adenia is a genus of flowering plants in the passionflower family Passifloraceae. It is distributed in the Old World tropics and subtropics. The centers of diversity are in Madagascar, eastern and western tropical Africa, and Southeast Asia. The genus name Adenia comes from "aden", reported as the Arabic name for the plant by Peter Forsskål, the author of the genus.
Quassia amara, also known as amargo, bitter-ash, bitter-wood, or hombre grande is a species in the genus Quassia, with some botanists treating it as the sole species in the genus. The genus was named by Carl Linnaeus who named it after the first botanist to describe it: the Surinamese freedman Graman Quassi. Q. amara is used as insecticide, in traditional medicine and as additive in the food industry.
The genus of the myrrhs, Commiphora, is the most species-rich genus of flowering plants in the frankincense and myrrh family, Burseraceae. The genus contains approximately 190 species of shrubs and trees, which are distributed throughout the (sub-) tropical regions of Africa, the western Indian Ocean islands, the Arabian Peninsula, India, and South America. The genus is drought-tolerant and common throughout the xerophytic scrub, seasonally dry tropical forests, and woodlands of these regions.
Citropsis is a genus of flowering plants in the citrus family, Rutaceae. They are known generally as African cherry oranges. They are native to Africa.
Pierreodendron is a genus of plants in the family Simaroubaceae.
Xylopia is a genus of flowering plants in the family Annonaceae. They are mostly trees and some shrubs. There are about 160 species distributed in Asia, Africa, and the Americas.
Ottelia is a genus of an aquatic plant family Hydrocharitaceae described as a genus in 1805. The genus is native to tropical and subtropical regions of Africa, Asia, South America, and Australia.
Quassinoids are degraded triterpene lactones of the Simaroubaceae plant family grouped into C-18, C-19, C-20, C-22 and C-25 types. The prototypical member of the group, quassin, was first described in the 19th century from plants of the genus Quassia from which it gets its name. It was isolated in 1937, and its structure elucidated in 1961. XIX
Meiocarpidium is a genus of plants in the family Annonaceae. It is distributed in Cameroon, The Central African Republic, The Republic of the Congo, and Gabon. Adolf Engler and Ludwig Diels, the German botanists who first formally described the genus, named it after the small number of carpels in the flowers.
Meiocarpidium lepidotum is a species of plant in the family Annonaceae. It is native to Cameroon, The Central African Republic, The Republic of the Congo, and Gabon. Daniel Oliver, the English botanist who first formally described the species using the basionym Unona lepidota, named it after rust-colored, shiny scales on its branchlets, the underside of its leaves and its buds.
Cycnium is a genus of flowering plants in the family Orobanchaceae. Its native range is tropical and southern Africa and Madagascar.
Iodes is a genus of flowering plants belonging to the family Icacinaceae.
Simaba is a genus of flowering plants belonging to the family Simaroubaceae.
