Lime (fruit) – Wikipedia, the free encyclopedia

http://en.wikipedia.org/wiki/Lime_(fruit):

It was later discovered that the greater effectiveness of lemons derived from the four-fold higher quantities of vitamin C contained in lemon juice compared to the West Indian limes used by the British.

I really love the home-grown lime from Brazil and here on Martinique.
(BTW: the hummingbird just visits our garden’s bushes and tree.)
