Usage of The Term "ex"
When "ex" is a component of the author citation, it denotes the fact that an initial description did not satisfy the rules for valid publication, but that the same name (with relevant attribution) was subsequently validly published by a second author or authors (or by the same author in a subsequent publication). For example:
- Andropogon aromaticus Sieber ex Schult.
indicates that Josef Schultes validly published this name (in 1824 in this instance), but his description was based on an earlier description by Franz Sieber. (Note that in Botany, the author of the earlier name precedes the later, valid one; in zoology, this sequence (where present) is reversed).

“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)

“We term sleep a death ... by which we may be literally said to die daily; in fine, so like death, I dare not trust it without my prayers.”
—Thomas Browne (1605–1682)
