Physalis angustifolia

Physalis angustifolia is a species of the genus Physalis (Physalis ) in the nightshade family (Solanaceae ).

Description

Vegetative characteristics

Physalis angustifolia is a perennial plant with a deep -lying underground rhizome, which is often thin and flat. The stems are 15 to 60 cm high and are erect or spreading along the bottom and are increasing. The stems and leaves are usually glabrous, rarely the leaf edges are short, branched trichomes that are 1 mm or less in length, occupied.

The leaves are sessile, narrowly spatulate to linear - lanceolate, they are 3-10 (rarely to 12 ) cm long and 0.2 to 1.5 (rarely to 2 ) cm wide. The tip is blunt to pointed, the leaf margin is entire, and the leaf base tapering to the stem axis.

Flowers

The flowers are at 11 to 24 (rarely to 32 ) mm long pedicles. The calyx has a length of 5 to 9 ( rarely to 10) mm and (rarely only 1) with 1.5 to 3.5 mm long lobes occupied. Up on the edges it is glabrous or occasionally with short, branched trichomes that are 1 mm or less in length, occupied. The crown has a length of 11 to 15 ( rarely 8-16 ) mm and is drawn in the throat with ocher to green, inconspicuous spots. The main artery of the petals is typically colored purple or red. The dust bag having a length of 2.5 to 3.5 mm and are twice the width of the filaments.

Fruits

The fruits are orange-colored berries. The stem is extended to the fruit at 15 to 25 ( rarely to 42) mm. The cup is 2-3 ( often 1.5 to 4 ) inches long, and measures 1.5 to 2.5 mm in diameter. To fruit maturity, it is usually colored orange.

Occurrences and locations

The species is widespread in southern Alabama, Louisiana and Mississippi, and along the belonging to Florida part of the coast of the Gulf of Mexico. It grows on the dunes of the Gulf and on disturbed soils in the sand. On the Florida peninsula the type walteri hybridized with physalis, so that there populations with characteristics of both species can be found.
