I've got an old book (30s) entitled The Wright Encyclopaedia of Gardening
and the plant description structure is

Order: A division of the Vegetable Kingdom
Genus: A subsidiary part of the Order.
Species: A subsidiary part to the Genus.

So, are the terms different today ?

Still the same, eg:

Kingdom Plantae
Division Magnoliophyta
Class Magnoliopsida
Order Magnoliales
Family Magnoliaceae
Genus Magnolia
Species Magnolia virginiana

There are a few 'subs' and 'supers' which are available, eg sub-order
