description

Solanum kulliwaita grows as a woody liana or climbing shrub of indefinite length or height. The branches are bent. The stems are loosely covered with trichomes , which fall off with age. These are 0.5 to 1 millimeter long, are single-row and consist of several cells. The young shoots are covered with simple or branching, single-row trichomes that are between 0.5 and 1 millimeter long. The shiny bark is dark red-brown in color on older stems.

The sympodial units contain several leaves . The simple leaves are between 2 and 8.5 inches long and between 1 and 3 inches wide. The slightly fleshy leaf blade is elliptical to lanceolate in shape. Their base is pointed to tapering to a point, the point is pointed and their entire leaf margins are sometimes bent back and densely covered in the lower third with simple trichomes. The upper side of the leaf is sparsely covered with simple or branched, single-row trichomes, with the density increasing towards the midrib. Seven to nine pairs of primary leaf veins extend from the leaf axis and turn black-brown when they dry out. The 0.7 to 2 centimeter long leaf stalk is densely covered with gold-colored, simple or branched, single-row trichomes.

The inflorescences are terminal or on the side of the stems. They are 9 to 11 inches long and are three to five times branched. Each of the inflorescences consists of ten to twenty flowers. The inflorescence is densely hairy with simple, single-row, purple-colored trichomes that reach a length of 0.3 to 1 millimeter. The upright to nodding flower stalk becomes 1.5 to 3.5 centimeters long and about 0.5 millimeters thick at the base and about 1 millimeter thick at the top. It is densely covered with trichomes. At the base, the flower stalk is bent like a hinge and provided with a small shell that remains on the inflorescence as a cone about 2 millimeters long. The flower stalks are irregularly 0.5 to 5 millimeters apart.

The five-fold flowers are always fully developed. The cup-shaped calyx tube is between 2 and 2.5 millimeters long and covered with 2.5 to 3.5 millimeters long, wide triangular lobes. The dense hairs of the calyx resemble that of the rest of the inflorescence. The purple crown measures 2.3 to 2.5 centimeters in diameter, lobes in a star shape up to two thirds of the way to the base. The corolla lobes are 9 to 12 millimeters long and 4 to 5 millimeters wide and their edges and tips are densely hairy. The hairless stamens have grown together to form a tube and the free-standing part is between 1 and 2 millimeters long. The yellow anthers are elliptical in shape with a length of 3.5 to 4.5 millimeters and a width of 1 to 1.5 millimeters. They open through pores at the tips, which enlarge into slits with age. The ovary is hairless. The stylus is 7 to 8 millimeters long and hairless. The head-shaped scar is finely papillary.

The fruits known for the first description may be immature. These are black berries , which are spherical in shape with a diameter of about 1 centimeter. The hairless pericarp is thin and not shiny. The berries stand on a woody, more or less hanging stem that is 1.5 to 1.7 centimeters long and about 1.5 millimeters thick at the base. Nothing is known about the seeds.

distribution and habitat

So far, Solanum kulliwaita has only been found at two sites on the Mesa Pelada , near Machu Picchu , in the Maranura district in southern Peru and belonging to the province of La Convención . The species thrives at altitudes of 2400 to 2600 meters, where it grows in cloud forests on eastern slopes.
