Don't shoot the messenger :)
This just came on my FB feed.
Can something be a fruit if it does not come from a seed? Is it an herb if it comes from a bulb?
If the word "banana" came from Arabic for "finger" - it came a LONG way. They don't sound much alike besides the "B" sound.
Since you can find mammals that lay eggs, I'm sure you can still call it a fruit from a bulb. Nature is full of fun little oddities like that.
