brought vanilla to Europe, but for more than 300 years the pollination mechanism remained a mystery. Morren was the first to discover a method for artificial pollination, which made it possible to cultivate vanilla in the French colonies. Pollination of vanilla pods is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841,
Edmond Albius Edmond Albius (1829 – 9 August 1880) was a horticulturalist from Réunion. Born into slavery, Albius became an important figure in the cultivation of vanilla. At the age of 12, he invented a technique for pollinating vanilla orchids quickly and ...

, which refers to the scientific discipline that studies the seasonal cycles of animals and plants. Morren first used the term phenology in 1849 during a public lecture at the Academy of Brussels. The first use of the term phenology in a scientific paper dates back to 1853 when Morren published “Souvenirs phénologiques de l’hiver 1852-1853” (“Phenological memories of the winter 1852-1853”). This paper describes an exceptionally warm winter when plants exhibited unusually phenological patterns. This botanist is denoted by the author abbreviation C.Morren when citing a
