Jaquin, Nikolaus Joseph. – Cytisus Tener from ‘Icones plantarum rariorum’

Sisymbrium hispanicum, also known as Spanish rocket, is a plant species from the rocket genus (Sisymbrium) within the cruciferous family (Brassicaceae). It is native to the Pyrenees and the northern and central parts of the Iberian Peninsula. It is a biennial or perennial herbaceous plant. “Cytisus tener” refers to a plant that is often used as a botanical term and is associated with the white clover (Cytisus). Nikolaus Joseph Freiherr von Jacquin was a scientist who studied medicine, chemistry and botany. Born in Leiden in the Netherlands, he studied medicine at Leiden University, then moved first to Paris and afterward to Vienna. In 1752, he studied under Gerard van Swieten in Vienna. Between 1755 and 1759, Jacquin was sent to the West Indies, Central America, Venezuela and New Granada by Francis I to collect plants for the Schönbrunn Palace, and amassed a large collection of animal, plant and mineral samples. In 1797, Alexander von Humboldt profited from studying these collections and conversing with Jacquin in preparation of his own journey to the Americas. In 1763, Jacquin became professor of chemistry and mineralogy at the Bergakademie Schemnitz (now Banská Štiavnica in Slovakia). In 1768, he was appointed Professor of Botany and Chemistry and became director of the botanical gardens of the University of Vienna. For his work, he received the title Edler in 1774. In 1783, he was elected a foreign member of the Royal Swedish Academy of Sciences. In 1806, he was created a baron. In 1809, he became a correspondent of the Royal Institute, which later became the Royal Netherlands Academy of Arts and Sciences.
