Calamansi (Citrofortunella microcarpa â this is the scientific name, notice how a scientific name is written?) is a type of citrus that is native to the Philippines. It is also known as calamondin, Panama orange or acid orange.It is very sour hence its popularity as souring agent for sinigang and sawsawan (dipping sauces). It is also one of the more common backyard trees in Philippine homes (along with papaya and guava).t is also known as calamondin, Panama orange or acid orange.

The most famous such example is Secretariat. His autopsy showed beyond a shadow of a doubt that he had an oversized heart, weighing in at 22 pounds, nearly three times that of the average thoroughbred, and more than three times that of an average non-thoroughbred horse.
Today's the 40th anniversary of Secretariat's victory at the Belmont Stakes. The horse won by an unfathomable 31 lengths to clinch the 1973 Triple Crown. Secretariat was the first Triple Crown winner since 1948, and there have only been two since. Secretariat averaged 37.5 miles an hour during the race and finished in 2:24, two seconds faster than the next best times at the Belmont Stakes. Easy Goer ran 2:26 in 1989, and A.P. Indy did the same three years later.
