Physalis gracilis is a plant type from the genus of jujubes ( Physalis ) in the family of the nightshade family (Solanaceae). It occurs in Central America and Mexico .
description
Physalis gracilis are herbaceous plants of up to 1.2 m in height that grow upright or climb. The shoot axes are hairless to tomentose, the trichomes are conspicuous, 1 to 1.5 mm long. The lower part of the stem axis becomes bald with age, and the hair remains on the slightly swollen nodes . Occasionally, roots grow from the nodes and form an adventitious root system . The leaves are up to 10 cm long, ovate, pointed at the tip, rounded or blunted at the base. The edge is almost entire, the leaf blade is covered with a few short trichomes. The petiole is as long as the leaf blade or slightly shorter and slightly hairy on top.
The slender, 7 to 21 mm long flower stalks are longer than the calyx during the flowering phase and have long, upright and protruding trichomes. The flowers have an approximately 5 to 10 mm long calyx , the calyx lobes are pointed-triangular, often have bent back tips, are bent up around the median nerve and are hairless or densely covered with long, upright and protruding trichomes. The crown has a dark, conspicuous “eye” in the middle, is 9 to 13 mm long and bends back so that the completely open crown has a diameter of up to 16 mm. The stamens are slender but somewhat flattened, the anthers are yellow or blue, 3 to 4 mm long.
The fruits are 8 to 15 mm large berries that stand on a slender to slightly thickened stem 10 to 20 mm in length. The enlarging calyx is ten-edged or round, 20 to 30 mm long and covered with a few long hairs that do not stand on the calyx ribs.
The number of chromosomes is 2n = 24.
Similar species
Typical of this species is the long, whitish hair near and on the nodes and on the calyx. In Physalis lagascae , however, the calyx hairs are close to the calyx ribs, while the hairs standing close to the ribs in Physalis gracilis show no signs of originating from them. The anthers are larger than in other species, and the species shares the ten-edged calyx with the species Physalis angulata .
Occurrence and locations
The occurrence of the species extends from Bocas del Toro ( Panama ) to the west through all of Central America to northern Mexico . The species prefers moist locations.
