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.
But then Secretariat began pulling away as he ran the mile in a stunning 1:34 1/5. The Meadow Stable colt reached the mile and a quarter in 1:59, faster than he ran in setting the Kentucky Derby record. Alone, Secretariat wasn't racing against other horses, but against the clock, against history. When he finished the last quarter in a mind-blowing 25 seconds, there wasn't another horse in the same zip code. The magnificent chestnut finished an amazing 31 lengths in front.
