Durio dulcis, known as durian marangang (or merangang), red durian, tutong, or lahong, is a fairly large tree in the genus Durio. It can grow up to 40 m tall. The husk of its fruit is dark red to brown-red, and covered with slender 15-20 mm long spines. The fruit flesh is dark yellow, thin and deep caramel-flavoured with a turpentine odour. The fruit of this species is considered by many to be the sweetest of all durians.
