Physalis latiphysa is a plant type from the genus of jujubes ( Physalis ) in the family of the nightshade family (Solanaceae).
description
Physalis latiphysa is a herbaceous plant that grows to a height of 30 to 45 cm . The stem axis is densely hairy with multicellular, glandular trichomes . The leaves are silky hairy, 5.5 to 16.0 cm long, with the petioles 2.5 to 7.5 cm and the leaf blades 3.0 to 8.5 cm. The leaf blade has a width of 1.5 to 7.0 cm, the tip is pointed, the base is blunt, rarely inclined by up to 3 mm. The leaf margin is whole or seldom serrated with up to four teeth per side.
The flowers are on 4 to 11 mm long pedicels , the calyx has pointed calyx tips, is hairy glandular and 2.2 to 2.5 mm long and 1.0 to 1.5 mm wide. The crown is creamy yellow, each of the five fused petals is provided with five dark blue markings on the inside, the crown diameter is 3.5 to 4.0 mm. The stamens are hairy and colored blue, the anthers blue or mottled blue with a length of 1 mm. The flowering period is between July and September.
When the fruit ripens, the stem extends to 1.8 to 2.0 cm, the calyx enlarges to 3 to 4 cm in length and 2.5 to 3.5 mm in diameter, often it is as long as it is wide. The entire surface of the calyx is hairy glandular. The cross-section of the calyx is strongly pentagonal. The fruit is a spherical berry 1.3-2.0 mm in diameter, non-sticky and contains a multitude of brown, granular seeds 2.5 mm in diameter .
Occurrence
The species occurs in southern Arizona , but is also known from a collection each from Sonora , Guanajuato and Michoacán .
Systematics
Physalis latiphysa is classified within the genus of the bladder cherries ( Physalis ) in the section Epeteiorhiza of the subgenus Rydbergis . It resembles Physalis pruinosa most , differs from it mainly in the shorter flower stalks and the blue anthers. These characteristics can also be observed in Physalis nicandroides , in contrast to this species, Physalis latiphysa has longer trichomes, thinner fruit stalks and a paper-like and non-leathery calyx. Both species also differ from Physalis latiphysa in that they have sticky fruits.
