description
Physalis pumila is a perennial, 15 to 40 centimeter high plant that grows from a sturdy rhizome located deep underground . The stems grow upright, branch irregularly at the upper nodes , the branches are ascending. The plant has sticky hairs, the hairs consist of articulated, simple or two to three times branched trichomes that are 0.5 to 2 millimeters long. The leaf blades are ovate to ovate, lanceolate, 3 to 8 (rarely up to 10) centimeters long and 2 to 5 centimeters wide. They too are sticky hairy. The leaf margin is entire to wavy, seldom curved and serrated. The base of the leaf blade is pointed, it is pointed towards the front. The leaf stalks can reach a tenth to two fifths of the length of the leaf blade.
The flowers stand individually in the axils of the leaves. The calyx is 6 to 12 millimeters long, is sticky hairy and has 3 to 5 (rarely 2.5 to 6) millimeter long calyx lobes. The flower stalk is usually 14 to 30 (rarely only 7) millimeters long. The crown is 11 to 16 millimeters long, yellow, with a pale brown or green tinge in the crown throat, but without making out clearly defined spots. The anthers are yellow, 2 to 3 millimeters long and as wide as the stamens .
The calyx, which is greatly enlarged when the fruit is ripe, is green, the cross-section is ten-angled and indented at the base. It becomes 2.5 to 3.5 (rarely up to 4) centimeters long and measures 1.5 to 3 centimeters in diameter. The flower stalk extends to 25 to 55 millimeters.
The flowering period extends from the beginning of March to September.
The number of chromosomes is 2n = 24.
