Vegetative characteristics
Jaltomata spooneri is up to 2 meters tall shrub . Its young branches are green, angular and sparsely covered with tree-like, branched and single-row, unbranched trichomes, some of which are glandular. The older branches are woody, twisty and have cork pores . The leaves are alternate, often in pairs. The leaf blade is papyrus-like and is up to 11.7 inches long and 8.6 inches wide. It is lanceolate or egg-shaped, pointed towards the front and finely haired on both sides. The edge of the leaf is completely or slightly curled up and ciliate. The leaf stalks are up to 2.7 inches long.
Inflorescences and flowers
The inflorescences are in the armpits and usually consist of two, occasionally three flowers . The inflorescence stalks are up to 15 millimeters long and round, the flower stalks are 7 to 20 millimeters long, green and provided with five raised, longitudinal elevations. The calyx is green, turning during the flowering period and up to 23 millimeters in diameter. The calyx lobes are triangular, hairless on the inside and covered on the outside with glandular unbranched and forked trichomes. On the unripe fruit, the calyx can be up to 25 millimeters in diameter. The crown is urn-shaped-tubular and provided with a broad, bent-back, ten-lobed crown hem. It is 1.5 to 2.0 centimeters long and colored light green to whitish. In some specimens, the longitudinal veins of the crown are colored purple. The outside is sparsely hairy with unbranched trichomes, occasionally these can be glandular. The coronet measures 2.5 centimeters in diameter and is covered with five cream-green, narrow triangular corolla lobes that alternate with five lighter lobes. The edge of the coronet is eyelashed.
The stamens are up to 27 millimeters long. The stamens are colorless, hairless and elongate while the flower is open. The anthers, when they are cracked open and herbarized, are 2.1 to 2.7 millimeters long and prickly. You stand above the crown. At the base of the stamens these are widened so that depressions form between them, in which there is colorless nectar . The pollen grains measure 33 to 38 micrometers in diameter, approx. 92500 to 109000 pollen grains are formed per flower. The stylus is 26 to 28 millimeters long and pale green. The scar is darker than the stylus and stands 0 to 2 millimeters behind the opened anthers. It is head-shaped and bilobed. The flower base encloses the base of the ovary .
Fruits and seeds
The fruits are almost spherical berries . It is believed to grow up to 13 millimeters in size and be orange in color when ripe. The seeds are light brown and almost kidney-shaped to almost circular.
Occurrence and locations

Botanical history
The first description of the species was published in 2013 by Thomas Mione and Segundo Leiva. The Art Epithet was given in honor of David Spooner for his support for Mione by donating Yaltomata seeds and plants. The type specimen was collected on January 9, 2010 by Thomas Mione, Segundo Leiva G. and Leon Yacher in the province of Sandia. The holotype evidence is in the herbarium of the Universidad Nacional de San Agustín in Arequipa , isotype evidence is kept in the herbaria of the Field Museum of Natural History in Chicago and the New York Botanical Garden .
