Nolana thinophila is a plant type from the genus Nolana in the family of the nightshade family (Solanaceae). The species occurs exclusively in the south of Peru .
description
Nolana thinophila are recumbent, loosely branched subshrubs , the younger branches of which are succulent . The plants are indistinctly hairy and more or less sticky. The stems are slightly woody, 1.5 to 3 mm thick, the internodes are 1 to 5 cm long. The leaves are spatulate, 1 to 3 cm long and 1.5 to 3 mm wide. The tip is rounded or truncated, the base is tapered piece by piece.
The flowers are on 6 to 15 mm long pedicels , which are bent back to fruit ripeness. The calyx is 6 to 7 (rarely up to 8) mm long, split, but not set with teeth. The calyx tube is cylindrical and 2 to 3 mm long. The crown is blue, 1.5 to 2 cm long, the corolla tube is longer than the calyx. The inside of the crown is slightly hairy.
When the fruit ripens, the calyx widens to a width of 4 to 5 mm. The collective fruits usually consist of five sub-fruits that are upright, black and elongated, reach a length of 3 to 5 mm and a thickness of 2 to 2.5 mm. The tip of the partial fruits is rounded and provided with a large scar-like crack. The fruits stand on a ten to fifteen- toothed flower base , the ovary bulge is only about 0.5 mm high and 2 mm wide.
distribution
The species is endemic to southern Peru and occurs in the departments of Ica and Arequipa .
