Subtribe in the context of "Hippeastrum"

In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe.

In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina".

Bubalina is a subtribe of Bovini (wild cattle) that includes the various species of true buffalo. Species include the African buffalo, the anoas, and the wild water buffalo (including the domesticated variant water buffalo). Buffaloes can be found naturally in sub-Saharan Africa, South Asia and Southeast Asia, and domestic and feral populations have been introduced to Europe, the Americas, and Australia. In addition to the living species, bubalinans have an extensive fossil record where remains have been found in much of Afro-Eurasia.

American bison are commonly referred to as "buffalo" but are not members of Bubalina.

Panina is a subtribe of tribe Hominini; it comprises all descendants of the human-chimpanzee last common ancestor (LCA) that are not of the branch of human lineage—that is, all those ancestors of the type genus Pan (chimpanzees and bonobos). This split/divergence occurred around 8 to 6 million years ago (mya), which compares with a range of other estimates for this event—likely extended by periods of hybridization—of from 15 to 3 mya. Fossils from this subtribe are typically rare because they tend to live in environments with poor fossilization. Some of the earliest chimpanzee fossils are 500,000 years of age.

The Bambuseae are the most diverse tribe of bamboos in the grass family (Poaceae). They consist of woody species from tropical regions, including some giant bamboos. Their sister group are the small herbaceous bamboos from the tropics in tribe Olyreae, while the temperate woody bamboos (Arundinarieae) are more distantly related. The Bambuseae fall into two clades, corresponding to species from the Neotropics (subtribes Arthrostylidiinae, Chusqueinae, and Guaduinae) and from the Paleotropics (subtribes Bambusinae, Hickeliinae, Melocanninae, and Racemobambosinae).

Stingless bees (SB), sometimes called stingless honey bees or simply meliponines, are a large group of bees (from about 462 to 552 described species), comprising the tribe Meliponini (or subtribe Meliponina according to other authors). They belong in the family Apidae (subfamily Apinae), and are closely related to common honey bees (HB, tribe Apini), orchid bees (tribe Euglossini), and bumblebees (tribe Bombini). These four bee tribes belong to the corbiculate bees' monophyletic group. Meliponines have stingers, but they are highly reduced and cannot be used for defense, though these bees exhibit other defensive behaviors and mechanisms. Meliponines are not the only type of bee incapable of stinging: all male bees and many female bees of several other families, such as Andrenidae and Megachilidae (tribe Dioxyini), also cannot sting.

Some stingless bees have strong mandibles and can inflict painful bites. Some species can present large mandibular glands for the secretion of caustic defense substances, secrete unpleasant smells or use sticky materials to immobilise enemies.

Ricinus communis, the castor bean or castor oil plant, is a species of perennial flowering plant in the spurge family, Euphorbiaceae. It is the sole species in the monotypic genus, Ricinus, and subtribe, Ricininae.

Its seed is the castor bean, which despite the term is not a bean (as it is not the seed of a member of the family Fabaceae). Castor is indigenous to the southeastern Mediterranean Basin, East Africa, and India, but is widespread throughout tropical regions (and widely grown elsewhere as an ornamental plant).

Amaryllis (/ˌæməˈrɪlɪs/) is the only genus in the subtribe Amaryllidinae (tribe Amaryllideae). It is a small genus of flowering bulbs, with two species. The better known of the two, Amaryllis belladonna, is a native of the Western Cape region of South Africa, particularly the rocky southwest area between the Olifants River Valley and Knysna.

For many years there was confusion among botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name 'amaryllis' is mainly used for cultivars of the genus Hippeastrum, widely sold in the winter months for their ability to bloom indoors.
