Female including fruiting pedicels 0-1 mm; sepals as in male; disk glabrous to pubescent especially at margin; ovary pubescent; stigmas (2 or)3(-5).
Black currant tree fruits
Fruit an ellipsoid drupe, laterally compressed, 3-4(-5) × 2.5-3(-3.5) mm, sparsely pubescent; style terminal to more rarely subterminal; fruits borne on spike and ripen over a period of a few weeks and therefore harvested in more than one picking; fruits taste sour due to dominance by acids in spite of the presence of sugar.
Though the fruits taste sour but still these are eaten locally. The taste, particularly the degree of sourness might vary from place to place. These can be used for making jam or jelly because of high pectin content.
The fruits are also used to season meat and fish preparations in the Philippines.
The leaves are also sour in taste. These are used for flavouring.
The leaves are used as a medicine for headaches; the stem is used as a medicine to stimulate the menstrual flow. The fruit is eaten locally or used as a purgative.
