clip art wiki:
ip art, in the graphic arts, is the use of images either copied or physically cut (hence the term) from pre-existing printed works, either books that have entered the public domain, or books specifically published for such use (which, if they contain images that are not in the public domain, include a license fee in the cover price). It is also not uncommon for large organizations to provide their local divisions or chapters with clip art (either physical or electronic) of their logos, mascots, and so forth, in order that local publications may have a unified appearance. It is also rather common for those producing documents with limited distribution to use images from non-public-domain sources for which they have not paid license fees, such as coloring books, newspapers, magazines, and such, although some magazines, particularly those dealing with hobbies will publish images explicitly licensed to the magazine purchaser for use as clip art.

twig wiki:
[wig is a small terminal branch section that bears leaves, buds and usually the flowers and fruit of plants. Only dicotyledonous flowering woody plants and most gymnosperms have true twigs; monocotyledons and tree ferns do not.Twigs are critically important in identification of trees, shrubs and vines, especially in wintertime. The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark is also important, as is the thickness and nature of any pith of the twig.
