description
Vegetative characteristics
Physalis walteri is a perennial plant with a rhizome lying deep underground . The stems reach heights of 5 to 40 cm and, like the lower branches, are erect or spread along the ground and are ascending. The stems and leaves are sparsely to densely covered with branched trichomes , which can be 1 mm long or shorter.
The leaf stalks are 1/6 to 1/2 times as long as the leaf blade . The leaf blade is broadly elliptical or ovate to ovate-lanceolate, 3.5 to 9 (rarely 2.5 to 13) cm long and 1.5 to 5 (rarely 1 to 7) cm wide. Towards the front, the leaves are blunt or pointed, the edge of the leaf is entire or, rarely, wavy, the base of the leaf is rounded or tapering to a point.
blossoms
The flowers are solitary in the leaf axils. The flower stalks are 9 to 25 (rarely up to 35) mm long. The calyx is 6 to 9 (rarely 5 to 11) mm long and with 1.5 to 4 (rarely up to 5) mm long tips at the flowering time. It is densely to sparsely covered with branched trichomes 1 mm or less in length. The crown is 11 to 15 (rarely 9 to 18) mm long and is clearly or indistinctly provided with dark to pale brown, ocher or green markings in the throat. The main veins of the individual petals can sometimes be purple or red in color. The anthers are 2.5 to 3.5 mm long, the stamens are just as wide as the anthers.
fruit
The fruits are orange colored berries . The stem extends on the fruit to 15 to 40 mm, the calyx enlarges to a length of 2 to 3.5 (rarely up to 4) cm and a diameter of 1.5 to 2.5 mm and is green in color.
Occurrence and locations
The species is mainly found on the Atlantic coast of Florida , Georgia , North and South Carolina and Virginia , but also occurs in the interior of Florida and Georgia and sporadically in the coastal areas of Alabama and Mississippi . It grows on dunes and disturbed sandy soils. On the Florida peninsula, the species hybridizes with Physalis angustifolia , so that populations with characteristics of both species can be found there.
