Etymology

Origin of citrus

1815–25; < New Latin, Latin: citron tree

Explanation

Oranges, grapefruits, lemons, and limes: all of these are fruits that belong to the citrus family. They share similar kinds of pulp, thick rinds, and the fact that they grow well in warm climates. If you live in Florida, then you know about citrus. Most of the country's oranges and other citrus come from Florida, with California a close second. But oranges aren't the only citrus fruits. There are lemons, limes, grapefruits, just to name just a few. You can recognize a citrus fruit by its brightly colored, thick, and peelable rind. Citrus fruits are juicy and pulpy and make for a great breakfast. Not for me, though. All the acid in citrus makes my stomach upset.
