from The difference between Aloes and Agaves page 

 Aloe, a member of the the lily family known as  Asphodelaceae (Aloaceae), and is native to parts of Africa and Arabia.

There are more than 450 species of aloe, ranging from 2 inches across to tree height.  Aloe vera, often grown as a houseplant and kept in kitchens, contains a gel that helps heal minor burns. Larger aloe, such as the 50 foot tall Aloe bainseii, has "a grotesquely thickened trunk and tapering branches that make it look like a character out of a Dr. Seuss story," according to The Book of Outdoor Gardening.
