Jaltomata weberbaueri is a plant type from the genus jaltomata in the family of the nightshade family (Solanaceae).
description
Jaltomata weberbaueri is an almost hairless, herbaceous or slightly woody plant that reaches a height of up to 2 m. The leaves are broadly ovate, rounded at the tip or tapering to a short point and covered with a more or less long or appendage-like tip. The leaf stalks are 0.6 to 1.5 cm in length.
The flowers appear from January to March and are on 1.5 to 3 cm long flower stalks . The crown is broadly bell-shaped, purple in color and streaked with green veins. Their length is 3.5 to 4.5 cm, the width between 3.5 and 5.5 cm, a noticeable red-orange nectar collects at the base . The anthers are about 4 mm long, the stylus is between 17 and 22 mm long.
The conical part of the calyx is about 12 mm long on the fruit. The fruit is an orange berry with a diameter of 15 to 16 mm. A berry found on a wild plant was 14 × 18 mm in size and contained 350 seeds .
Distribution and locations
The range of the species is in the Peruvian region Ancash . The locations are mostly grassy areas covered with isolated shrubs and damp ravines at altitudes between 2800 and 3800 m.
Botanical history
The species was first described in 1906 by Udo Dammer as Saracha weberbaueri . The species epithet honors the botanist August Weberbauer , who collected the type specimen of the species on March 27, 1903 in the Peruvian province of Ocros . In 1924 Georg Bitter described a subspecies Saracha weberbaueri ssp based on a plant also collected by Weberbauer . palascana . This subspecies was first raised to species rank by Francis Macbride in 1930 as Saracha palascana , but in 1962 it was placed as a synonym for Saracha weberbaueri in the "Flora of Panama" . Both the herbarium of the species named by Dammer and the herbarium of the subspecies named by Bitter, both of which were stored in the Berlin-Dahlem herbarium , were destroyed during the Second World War. When the species was transferred to the genus Jaltomata in 1992, the authors Thomas Mione and Felix Coe initially did not determine a lectotype . Further herbarium records of the type specimen were found later , so that in 2006 a herbarium from the herbarium of the Universidad Nacional Agraria La Molina was identified as the lectotype and another sheet from the herbarium of the Jardin botanique de Genève as the isolectotype. Since no further herbarium sheets were found of the type specimen of the subspecies, no current statement could be made about the status of the subspecies palascana .
