Living in North America, I was used to a very limited choice in varieties of mangoes. There were the large roundish red/green mangoes that usually came from Mexico or Hawaii. And there were the yellow, kidney-shaped ones called Manila, though I'm not sure if they actually came from the Philippines or not.
But here in Brazil, the variety of mangoes is astounding. On the website Toda Fruta there are photos of the most common Brazilian mango varieties. Here is a photo sampling from that site to show the spectrum of Brazilian mangoes. Each variety is labeled in the photo.
