Rare and little-known, the entire genus seems to be close to extinction.

Often the name serves to identify entire genera such as is the case with:

In older works, the entire genus is usually included within Pithecellobium.

Not only endemic species have evolved here, but entire genera and even families are unique to the islands.

The entire genus, however, contains more than 1,500 species and is very diverse in appearance, behavior, and breeding habitat.

Sometimes the entire genus is merged into Aquila.

In its botany not only species but entire genera and even families are unique to the island, and survive nowhere else.

A physical description of L. variegatus is, to a large extent, valid for the entire genus.

It has even been suggested that the entire genus is synonymous with Chiniquodon theotonicus.

In 2006 the baiji dolphin went extinct; the world lost an entire genus.
