Order names are printed in Roman (ordinary) letters, and begin with
a capital letter. Among animals, the names of most orders end in -a,
such as Anura (frogs and toads) and Chiroptera (bats), although bird
orders end in -iformes, such as Columbiformes (pigeons) and Stringiformes
(owls). In plants, order names generally end in -ales, such as Rosales
(roses).
