            SN/NC: Solanum Aculeatissimum, Solanaceae Family

Solanum aculeatissimum is a spiny, erect, few-branched shrub producing one or few stems from the base that grows 0.5 - 2 meters tall. The lower branches are ascending whilst the upper ones are spreading. The plant has a wide range of local medicinal applications. It is semi-cultivated as a prickly hedge plant.
The fruits are considered to be toxic. The sliced fruit is used as bait for cockroaches.
Although providing many well-known foods for people, including potato, tomato, pepper, and aubergine, most plants in the family Solanaceae also contain poisonous alkaloids. Unless there are specific entries with information on edible uses, it would be unwise to ingest any part of this plant. In Brazil it is considered a unwanted plague or weed that is widespread in the pastures. 
 Widely spread through tropical Africa, it is also found in Brazil. It is unclear to which area it was originally native.

Solanum aculeatissimum is een stekelige, rechtopstaande, weinig vertakte struik die een of enkele stengels produceert van 0,5 - 2 meter hoog vanaf de basis. De onderste takken stijgen terwijl de bovenste zich verspreiden. De plant heeft een breed scala aan lokale medicinale toepassingen. Het is semi-gecultiveerd als een stekelige haagplant.
De vruchten worden als giftig beschouwd. Het gesneden fruit wordt gebruikt als lokaas voor kakkerlakken.
Hoewel ze veel bekende voedingsmiddelen voor mensen leveren, waaronder de aardappel, tomaat, peper en aubergine, bevatten de meeste planten in de familie Solanaceae ook giftige alkaloïden. Tenzij er specifieke vermeldingen zijn met informatie over eetbaar gebruik, zou het onverstandig zijn om enig deel van deze plant in te nemen.
 Het wordt wijd verspreid door tropisch Afrika en komt ook voor in Brazilië. Het is onduidelijk in welk gebied het oorspronkelijk oorspronkelijk was.

No Brasil é manejado como praga e tem que ser erradicada especialmente dos pastos pelo perigo de toxicidade que carrega e pode matar animais. Entre seus nomes populares, temos: Arrebenta-cavalo, arrebenta-boi, joá, joá-bravo, joá-de-espinho, joá-melancia, mata-cavalo, jurubeba-branca.

Berenjena holandesa, hierba mora india son algunos nombres. Es un arbusto o maleza que lleva pequeñas frutas de 2-3 cm de color amarillo pálido después de las flores blancas con los característicos estambres amarillos.
El lugar de donde S. aculeatissimum es nativa aún no se ha determinado de forma concluyente. A pesar de su nombre común que sugiere un origen del sur de Asia, sin embargo, el origen de la planta es muy probable que sea África o América del Sur; mientras que los especímenes han sido identificados en Asia, es raro allí y se cree que es el resultado de una forma accidental o una introducción deliberada. Está estrechamente relacionada con otras especies de Solanum nativas tanto del África subsahariana como de América Central. África es el primer continente en el que S. aculeatissimum fue documentada. El botánico escocés Francis Masson encontró la planta cerca del Cabo de Buena Esperanza, durante los años 1772-1774, o durante una expedición posterior cuando se quedó en el sur de África desde 1786 hasta 1795. En América del Sur, la planta fue descrita por primera vez en 1816 -1821 por Augustin Saint-Hilaire.
