Carl Nägeli
Carl Wilhelm von Nägeli (26 or 27 March 1817 – 10 May 1891) was a Swiss botanist. He studied cell division and pollination but became known as the man who discouraged Gregor Mendel from further work on genetics. He rejected natural selection as a mechanism of evolution, favouring orthogenesis driven by a supposed "inner perfecting principle". Birth and education Nägeli was born in Kilchberg near Zürich, where he studied medicine at the University of Zürich. From 1839, he studied botany under A. P. de Candolle at Geneva, and graduated with a botanical thesis at Zürich in 1840. His attention having been directed by Matthias Jakob Schleiden, then professor of botany at Jena, to the microscopical study of plants, he engaged more particularly in that branch of research. He also coined the term "meristematic tissue" in 1858. Academic career Soon after graduation he became Privatdozent and subsequently professor extraordinary, in the University of Zürich; later he was calle ...

Acrochaetium Efflorescens
''Acrochaetium efflorescens'' is a small marine red alga. It is a small alga with erect filaments and spiral shaped plastids. The base is multicellular. The species shows an alternation of generations with both tetrasporic and gametophytic stages. It is found in the North Atlantic and has been recorded as an epiphyte An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phoroph ... on '' Cystoclonium purpureum''. References Acrochaetiales {{Rhodophyta-stub ...

Red Alga
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that lac ...

Gontran Hamel
Gontran Georges Henri Hamel (1883–1944) was a French phycologist. In 1927 he earned his doctorate in natural sciences with a thesis on the red algae genera '' Acrochaetium'' and '' Rhodochorton''. He is known for research performed in the "Laboratoire de Cryptogamie" at the Museum d'Histoire Naturelle in Paris. He reportedly died while trying to reach Paris by bicycle prior to its liberation in August 1944.BHL Taxonomic literature : a selective guide to botanical publications In 1924 with (1891–1944), he was co-founder of the journal ''Revue algologique''.
