Cajanus cajan
Authorship: The author or authors credited with publishing the scientific name. It is written after the name, sometimes with the year, for example L. (Linnaeus) in Zea mays L. An author in parentheses first published the name in another genus or rank.

Kingdom: One of the broadest ranks of biological classification. It groups organisms that share very basic features, for example plants (Plantae), animals (Animalia) or fungi (Fungi).
Plantae
Phylum: Rank below kingdom that groups organisms with a shared general body plan, for example chordates (Chordata), arthropods (Arthropoda) or vascular plants (Tracheophyta). In botany the same rank is also called division.
Tracheophyta
Class: Rank below phylum, for example mammals (Mammalia), birds (Aves), insects (Insecta) or monocot plants such as grasses and orchids (Liliopsida).
Magnoliopsida
Order: Rank below class that groups related families, for example grasses and their relatives (Poales) or bats (Chiroptera).
Fabales
Family: Rank below order that groups related genera. Family names usually end in -aceae in botany (for example Poaceae, the grass family) and in -idae in zoology (for example Felidae, the cat family).
Fabaceae
Genus: Rank that groups closely related species. Its name is the first word of a species' scientific name and starts with a capital letter, for example Zea in Zea mays.
Cajanus
Specific epithet: The second word of a species' scientific name. On its own it does not name the species: it always goes with the genus, for example mays in Zea mays.
cajan
Taxonomic rank: The level a name occupies in the hierarchy of biological classification, such as kingdom, family, genus, species or subspecies.
species
Reference species
Cajanus cajan
Taxonomic status: Whether the taxonomic catalogue the record comes from currently accepts this name for the organism, or treats it as a synonym of another accepted name or as doubtful.

Photos and conservation status

IUCN Red List category: The extinction-risk category that the International Union for Conservation of Nature (IUCN) assigns to a species on its Red List. EX Extinct: there is no reasonable doubt that the last individual has died. EW Extinct in the wild: it survives only in cultivation, in captivity or as a population far outside its past range. CR Critically endangered, EN Endangered and VU Vulnerable: the three threatened categories, from an extremely high to a high risk of extinction in the wild. NT Near threatened: close to qualifying as threatened. LC Least concern: evaluated and not threatened. DD Data deficient: there is not enough information to assess its risk. NE Not evaluated: not yet assessed against the criteria. It describes the risk of the species worldwide, not its situation in a project's area.
Not evaluated (NE)

Interacciones documentadas

GloBI says it is documented somewhere in the world. Biolitica answers whether it could happen here.

A documented interaction means it was recorded somewhere in the world. It does not mean it occurs here.

Blocks that do not sit under a navigation concept heading keep the source's own term: no navigation concept has been assigned to them yet.

is a host of 284 organisms

The authority declares no effect on this species for this term: neither that it harms it nor that it benefits it. In the source ontology symbiosis covers mutualism, commensalism and parasitism alike, so this block holds attackers and allies side by side.

Flower visit

has its flowers visited by 84 organisms

The authority declares no effect on this species for this term: neither that it harms it nor that it benefits it. Visiting a flower is not pollinating it. «Pollinates» is a different term and a different block, and merging the two is the measured defect that turned ~88 shared «pollinators» into birds and primates.

Pollination

is pollinated by 49 organisms

Documented uses and recommendations

Uses and recommendations that a source documents for this species beside a crop, each in its own context. They are the source's statements, not traits of the species and not Biolítica's recommendations, and none of them is a relation between two species.

Among the sources you can read, none documents a use or recommendation of this species beside a crop.
