I was under the impression that this was used when an individual didn't have a positive ID? Sort of a way to avoid having to say... I don't know what I've got but I think it is abc aff. xyz or I got the plant from so and so and they don't know exactly what it is so I'll just follow suit and look official and toss the aff. in for effect so as to not draw attention to the fact that I really don't know precisely what I have other than that it has an affinity toward abc aff. xyz?
Examples from Allen Lowrie's list of seed-
D. aff. paradoxa "orange flowers" Mount Bomford, Kimberley, West Australia
D. aff. paradoxa "metallic orange flower" north of Prince Regent River, Kimberley
D. aff. paradoxa "metallic orange flower" Mount Elizabeth, Kimberley
An example from Matt Hochberg of New York's site-
sp.aff.natalensis ('sp. big pink fl') *
aff. is an abbreviation for the word affinity, correct? So for all practical purposes, those who use this aff. don't really know exactly what they have they're just applying their best guess. Am I correct in this assumption?
What would be so wrong with simply listing a plant/seed as D. paradoxa "orange flowers" (not a positive ID but most likely it will fall into this classification)? *
