cactus

Definition from Dictionary, a free dictionary
The ideas of a time are like the clothes of a season: they are as arbitrary, as much imposed by some superior will which is seldom explicit. They are utilitarian and political, the instruments of smooth-running government.

Usage notes

Wikisource, as part of the 1911 Encyclopedia Wikiproject, has original text related to this article:

The most precise definition of cactus includes only plants from the New World (the Americas) belonging to the family Cactaceae. Only one species of cactus is native to the Old World, namely the genus Pereskea is a shrubby leafy cactus that grows in western Africa. However, many African species of the family Euphorbiaceae grow in forms and shapes that resemble large species of Cactaceae. These forms are colloquially referred to as “cactus”. In general, then, any usage of the term “cactus” to plants from the Old World refers to plants in the Euphorbiaceae.
