Species Ingenhoussia ericifolia

For Jan Ingenhousz or Ingen-Housz (1730–1799), Dutch physiologist, biologist and chemist. He is best remembered for showing that light is essential to plant cellular respiration, a vital step in the discovery of photosynthesis. He was a physician to the Austrian Empress Maria Theresa. He carried out research in electricity, heat conduction and chemistry and met both Benjamin Franklin and Henry Cavendish. In 1785 he described the irregular movement of coal dust on the surface of alcohol, and therefore has a claim as discoverer of what came to be known as Brownian motion. Ingenhousz was elected a Fellow of the Royal Society of London in 1779.
