In Oscar Henry's short story “The Trimmed Lamp”, Nancy describes why she declined a potential suitor who appeared to be a rather rich (or “swell”, as they refer to the rich in the story) individual:
And he’s got dactylis on him. Give me the real thing or nothing, if you please.
Google says “dactylis” is a type of plant, and I couldn’t find anything else. Does anyone by any chance know what’s “dactylis” in this context, and why Nancy considered it to be negative? Sources would be greatly appreciated as well :)
