Alexandre Louis Simon Lejeune
Alexandre Louis Simon Lejeune (23 December 1779 in Verviers – 28 December 1858 in Verviers) was a physician and botanist. In 1801 he entered the school of medicine in Paris, but was subsequently forced to abandon his studies due to military conscription. After finishing his military duties in late 1804, he relocated to Ensival as a physician. Three years later, he settled permanently in his hometown of Verviers. With Richard Courtois (1806–1835), he was co-author of "Compendium florae belgicae". He was a mentor to Marie-Anne Libert, who he introduced to Augustin Pyramis de Candolle. Libert named the genus ''Lejeunea'' (family Lejeuneaceae) in Lejeune's honor in 1820.

Verviers
Verviers (; wa, Vervî) is a city and municipality of Wallonia located in the province of Liège, Belgium. The municipality consists of the following districts: Ensival, Heusy, Lambermont, Petit-Rechain, Stembert, and Verviers. It is also the center of an agglomeration that includes Dison and Pepinster, making it the second biggest in the province and an important regional center, located roughly halfway between Liège and the German border. Water has played an important role in the town's economy, notably in the development first of its textile and later its tourist industries. As a result, many fountains have been built in Verviers, leading it to be named Wallonia's "Water Capital". The seats of the two Walloon public institutions for water distribution and water treatment are located in the town.

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Marie-Anne Libert
Marie-Anne Libert, (born 7 April 1782 in Malmedy, province of Liège, died 14 January 1865 in Malmedy) was a Belgian botanist and mycologist. She was one of the first women plant pathologists. She is sometimes referred to as "Anne-Marie Libert." Early life Marie-Anne Libert was born in Malmedy in April 1782, twelfth of the thirteen children of Henri-Joseph Libert and his wife Marie-Jeanne-Bernadine Libert (née Dubois). The parents, educated members of the middle class who ran a tanning business, recognised her intellectual potential. She was initially a pupil of the Sépulcrines of Malmedy. At the age of eleven her parents sent her to stay in Prüm in Germany to learn German and the violin, both of which she quickly mastered. Her father recognised his daughter's emerging interest in the exact sciences and taught her algebra and geometry, so that she could follow him into the business. She was enthusiastic and pushed the education well beyond the needs of commerce. At an age w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Lejeuneaceae
Lejeuneaceae is the largest family of liverworts. Most of its members are epiphytes found in the tropics, while others can be found in temperate regions. The main characteristics of the family are that: #The leaves are incubous. #Amphigastrium is usually present, sometimes reduced. #Leaves are divided into lobe and lobule. #Archaegonium in a perianth. Some large genera of the family are ''Lejeunea'', '' Ceratolejeunea'' (around 84 species,) and '' Cheilolejeunea'' (around 275 species,).
