description
Physalis missouriensis is an annual plant that grows 15 to 40 cm high . The stem axis is heavily branched and densely covered with multicellular, glandular trichomes with a length of 0.5 to 1.2 mm. The leaves are 3.5 to 9.5 cm long in total, of which the petioles make up 1 to 4 cm. The leaf blade is ovate to elongated and tomentose, occasionally more densely hairy on the leaf veins. It has a length of 2.5 to 5.5 cm and a width of 2.0 to 4.5 cm. The leaf is pointed towards the front, the base is blunt to heart-shaped, in some specimens also up to 5 mm oblique. The leaf margin is notched.
The flower stalks are 2.5 to 6.0 mm long, the calyx has a diameter of 1.4 to 2.0 mm at the time of flowering, has 1.5 to 2.5 mm long teeth and tomentose hair. The crown is yellow, hairy on the inside, has no markings and measures 7.0 to 9.5 mm in diameter. The stamens and anthers are yellow, blue or blue tinted and together 0.8 to 1.0 mm long. The flowering period extends from June to October.
When the fruit ripens, the stem has enlarged to a length of 5.5 to 9.0 mm, the calyx surrounding the fruit is 1.5 to 2.5 mm long, 1.5 to 2.0 mm wide, slightly pentagonal or round , only slightly inverted and felt-like hair everywhere. The ripe berries are spherical and 1.0 to 1.5 mm in diameter. They contain a large number of seeds , these have a diameter of 2.0 mm and are golden yellow, the surface of the seeds is small.
Occurrence
The species occurs exclusively in the US states of Arkansas , Kansas , Missouri and Oklahoma .
Systematics
Physalis missouriensis is classified within the genus of the bladder cherries ( Physalis ) in the section Epeteiorhiza of the subgenus Rydbergis . It differs from the other representatives of the section primarily in the calyx, which is almost round when the fruit is ripe, and the crown that is not shown. In addition, the species is similar to Physalis angulata , but differs from it in its completely tomentose-glandular hair and the flower stalks, which are never longer than 1 cm.
