Couma utilis, called the milk tree, sorvinha, sorveira, sorva (a name it shares with its larger relative Couma macrocarpa), and sorva-pequena, is a species of flowering plant in the subfamily Rauvolfioideae, native to the Orinoco and Amazon basins of South America.

[2][3] It is thought that C. utilis was on the verge of being domesticated by indigenous Amazonian peoples prior to the arrival of Europeans in the New World.

There are numerous soft, flattened, 3 to 4 mm (0.1 to 0.2 in) diameter seeds distributed evenly in the fleshy, sweet mesocarp.

[5] C. utilis grows well in the nutrient poor oxisols of the Amazon rainforest, preferring wet but unflooded areas between sea level and 500 m (1,600 ft) elevation.

[7] In cultivation in the central Amazon, a tree produces almost 40 kg (88 lb) of fruit per year, a yield of about 15 t/ha (6.0 long ton/acre; 6.7 short ton/acre).

[6] Its latex has many uses, including as a base (commercially called pendare[8]) for chewing gum, for boat-caulking and for whitewashing houses.

It is planted as an ornamental tree for its profusion of attractive pink to light purple flowers.
