The results showed of the study found that there were three types of asam gelugur in North Sumatra. Type 1 gelugur acid is named Gamboge Sumut Red . The characteristic feature is the color of the bright red petals (45 A) and the color of the leaf buds with red spots (Vivid red (41 A) but green is more dominant than red. Asam gelugur type 2 is called Camboge sumut Pink., its specific characteristic feature is the color of the petals yellowish pink (41 D) and the color of the leaf buds with broad red spots (41 A). The red color is more dominant than green. Asam gelugur type 3 is named Camboge Sumut Leaf.. Its distinctive feature is that it flowers but does not produce fruit, the color of the petals is a strong reddish orange (N 34 B), the color of the tops of the leaves on the shoots is strong yellowish green (144 A), Another differentiator. Type 3 tamarind leaves are bigger, thicker than female Camboge Sumut Red and Pink.
Among the three types of asam gelugur that grows the most is Asam Gelugur Camboge Sumut Pink .
