People will interpret things however they feel like interpreting it, even if you are meticulous about your meaning in an mdesc. To wit:
I played a melon-breasted woman. That was part of her sdesc. If you had bothered to actually read her mdesc, you'd discover her breasts were SHAPED like melons. Not that they were the size of melons. They were actually modest in size. But they were bulbous-shaped. Melon-shaped. She used to get shit from people all the time about the size of her boobs when in fact - there was nothing remarkable at all about their size, and her mdesc was very clear on that.
I also once played a character whose mdesc included a "gentle flare at her hips." Word got around that there was this chick with huge child-birthing hips hanging out at the bar. Why? Because I included the word "hips" in the mdesc and that's what people chose to latch on to.
The more obscure your reference, the less likely people will be to actually pay attention to it. Honey in Zalanthas used to come from kanks. There are no more kanks, and no living PC in the game would have been around before the kanks ceased to exist. Most PCs in the game can't read, so written descriptions would be lost on the vast majority of the populace. They'd have to rely on pictures, most of them ancient and primitively painted/drawn. It's very unlikely that any PC in the game would know a) that honey exists and b) that it's green.
As for plants - that's even tougher. The kalan-eyed man - are you saying his eyes are the COLOR of kalan fruits? Or the shape of kalan fruits? And if you mean the color of them, do you mean the outer rind, or the inner pulp (which is a very different color)?
I'm for clarity, personally. Even though - when I'm being clear, most people don't bother to read it anyway. At least I know I was clear, and that it was the fault of the reader for not, y'know, reading.
