Metroxylon is a genus of palm trees commonly known as sago palms. These tropical plants are primarily found in regions of Southeast Asia and the Pacific Islands. They thrive in wet, swampy areas and can grow up to 20 meters tall. The trunk is typically stout and can produce a large amount of starch-rich pith. The most notable species within this genus is Metroxylon sagu, which is cultivated for its edible starch. This starch is extracted from the trunk and processed to make sago, a staple food in many cultures. Sago is often used in desserts and as a thickening agent in various dishes.
