Charles François Antoine Morren

He also attended the lectures of Adolphe Quetelet at the Athénée, as well as those by Dekin on natural history, Laisné on chemistry, Jean Kickx (1775-1831) and Pierre-Léonard Vander Linden.

In 1841, Edmond Albius, a 12-year-old slave who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollinated.

Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier, but by the end of the 20th century, Albius was considered the true discoverer.

[5] Morren also coined the term phenology,[6] which refers to the scientific discipline that studies the seasonal cycles of animals and plants.

[9] This paper describes an exceptionally warm winter when plants exhibited unusually phenological patterns.
