Jaborosa runcinata flowering in Northeastern Argentina

Jaborosa is a genus of flowering plants in the family Solanaceae, the nightshades. There are about 23 species, [1] [2] [3] all native to South America, where they are distributed from Peru to Patagonia. Most occur in the Andes. [3] Most can be found in Argentina [4] and ten are endemic to the country. [3]

Description

Most Jaborosa are rhizomatous perennial herbs except J. bergii and J. sativa , which are annual or biennial. [3]

Ecology

Jaborosa rotacea is pollinated by flies, and J. runcinata is pollinated by moths. [3] Sphingid moths feed on the nectar of J. integrifolia . [4]

Chemistry

Like plants in several other genera of the Solanaceae, many Jaborosa species contain steroid-derived compounds called withanolides. [5] Many of the withanolides isolated from Jaborosa have been dubbed jaborosalactones. Some withanolides are phytotoxic, having effects on other plants such as inhibiting germination and radicle growth. [5] Some have antifeedant effects, deterring insects such as mealworms (Tenebrio molitor), [2] the Mediterranean fruit fly (Ceratitis capitata), [1] and the African cotton leafworm (Spodoptera littoralis) [6] from consuming the plant.
