Solanum pseudosycophanta is a species ofthe nightshade family (Solanaceae). It was first described in 2010 and isnative tosouthern Ecuador and northern Peru .
description
Solanum pseudosycophanta grows as a tree that can reach heights of growth of 5 to 30 meters and chest height diameters of 7 to 40 centimeters. The trunk is studded with pointed spikes with a broad base. The thin, grooved bark is light brown to reddish in color. Blossom-bearing branches are sparsely to densely covered with branched, star-shaped, reddish-light brown trichomes and are often unarmed.
The sympodial units contain two leaves arranged in pairs . The simple leaves are between 10 and 50 centimeters long and between 7 and 30 or more centimeters wide. The paper-like leaf blade is elliptical to ovate to lanceolate in shape. Their base is beveled or heart-shaped, the tip is pointed and the leaf margins are whole or slightly lobed. The leaf lobes have a broadly rounded or pointed tip. The dark green upper side of the leaf is moderately dense with simple and branched star-shaped trichomes. The trichomes are 0.5 to 5 millimeters long. The light green to whitish or yellowish green underside of the leaves is densely covered with whitish yellow, star-shaped trichomes, which are 1 to 1.5 millimeters long. Six to eight pairs of unreinforced leaf veins extend from the leaf axis . The leaf stalk becomes 5 to 9 centimeters long and is densely covered with trichomes, which are similar to those of the trunk.
The inflorescences are 2 to 10 centimeters long and are branched. Each of the inflorescences consists of ten or more flowers. The species is Andromonözisch , and one or a few hermaphrodite flowers are found at the base of the inflorescence. The inflorescence is densely hairy with star-shaped trichomes, which are similar to those of the trunk and is not reinforced. The flower stalk becomes 2.5 to 8 inches long. It is bent like a joint at the base. The flower stalks are 8 to 25 millimeters long and 1 to 5 millimeters apart.
Flowering specimens were collected in May and October to December and fruit bearing specimens were collected in May and November to December. The flowers are five-fold. The cup becomes 1 to 2 centimeters long, with the first 2 to 3 millimeters shaped like a tube. It is covered with about 11 millimeters long and 4 millimeters wide, tapering lobes. The underside of the calyx, densely haired with star-shaped trichomes, is unreinforced. The lavender to purple crown measures 5 to 8.5 centimeters in diameter, has a 12 to 20 millimeter long tube, and is lobed in a star shape up to more than half the way to the base. The petals are paper-like. The lanceolate corolla lobes are 2 to 3.5 centimeters long and 0.35 to 0.5 centimeters wide, and their underside is densely hairy with star-shaped trichomes in the middle part. The top of the corolla lobes is densely covered with branched, star-shaped trichomes. The hairless stamens have grown together to form a tube about 2.2 millimeters long, and the free-standing part is about 2 millimeters long. The yellow anthers are 11 to 16 millimeters long and around 1.5 millimeters wide. They open through pores at the tips, which enlarge into slits with age. The ovary is lightly hairy with star-shaped trichomes and becomes bald over time. The cylindrical pen of male flowers is from 4 to 4.4 millimeters in length and about 0.2 millimeters wide, hairy at the top right and the base slightly to moderately tight. The cylindrical style of hermaphrodite flowers is 16 to 18 millimeters long and around 1.1 millimeters wide, strongly curved at the tip and slightly to moderately hairy at the base. The head-shaped scar is bilobed.
When ripe, green, juicy berries are formed as fruits, which are elliptical to circular in shape with a diameter of 6 to 10 centimeters. The thick pericarp is hairless and has woody inclusions. The reddish brown to light brown seeds are 4 to 6.5 millimeters long and 3.5 to 4 millimeters wide, flattened kidney-shaped and have a wrinkled surface.
distribution and habitat
The natural range of Solanum pseudosycophanta includes southern Ecuador and northern Peru . The species thrives there at altitudes of 900 to 1900 meters. It grows in disturbed, tropical transitional and mountain forests, where it is mainly found in clearings and cleared areas.
