D augmented refers to a triad with a major 3rd and a #5. It implies no seventh interval and so any other alterations of the 9th are "adds".
D seventh with a raised or lowered 9th interval would be D7#9 or D7-9.

OK, then maybe it's the way the chord dictionary is labeling (as you said, "books, teachers, and charts don't all use consistent names for chords") . Because this chord dictionary lists the ...
D Augmented 9th as having the following notes: D - F# - A - C - E#
That "A" note is NOT augmented. (It's not a #5). This is a Dominant 7th chord with a sharped 9th only.
(And yet even though it's LISTED as "D Augmented 9th," on the side it says Symbol: D7#9).
