Henry William Ravenel was an American planter and botanist. He studied fungi and cryptogams in South Carolina, discovering a large number of new species. The genus Ravenelia is named after him, along with many of the species he discovered.
Paul Kummer was a minister, teacher, and scientist in Zerbst, Germany, known chiefly for his contribution to mycological nomenclature. Earlier classification of agarics by pioneering fungal taxonomist Elias Magnus Fries designated only a very small number of genera, with most species falling into Agaricus. These few genera were divided into many tribus. In his 1871 work, Der Führer in die Pilzkunde, Kummer raised the majority of Fries "tribus" to the status of genus, thereby establishing many of the generic names for agarics that are in use to this day. In 1874 he issued the work Der Führer in die Flechtenkunde with numbered lichen specimens arranged in two plates like an exsiccata.
Karl Ludwig Philipp Zeyher, was a botanical and insect collector who collected extensively in Cape Colony. He was the author, with Christian Friedrich Ecklon, of Enumeratio Plantarum Africae Australis (1835-7), a descriptive catalogue of South African plants.
The San Diego Natural History Museum is a museum located in Balboa Park in San Diego, California. It was founded in 1874 as the San Diego Society of Natural History. It is the second oldest scientific institution west of the Mississippi and the oldest in Southern California. The present location of the museum was dedicated on January 14, 1933. A major addition to the museum was dedicated in April 2001, doubling exhibit space.
Thaddeus Xaverius Peregrinus Haenke was a botanist who participated in the Malaspina Expedition, exploring a significant portion of the Pacific basin including the coasts of North and South America, Australia, the Philippines, New Zealand, and the Marianas. His collections of botanical specimens were the basis for the initial scientific descriptions of many plants in these regions, particularly South America and the Philippines. His extensive botanical work and far-ranging travel have prompted some to liken him to a "Bohemian Humboldt", named after Alexander von Humboldt, who made himself familiar with some of Haenke's findings before embarking on his journey to the Americas in 1799.
George Gardner was a Scottish biologist mainly interested in botany.
Reid Venable Moran was an American botanist and the curator of botany at the San Diego Natural History Museum from 1957 to 1982.
Marie Clément Gaston Gautier was a French botanist and agriculturalist.
Gaspard Joseph Benedict Balansa, also known as Benjamin Balansa or Benedict Balansa, was a French botanist.
Josephine Elizabeth Tilden was an American expert on pacific algae. She was the first woman scientist employed by the University of Minnesota. Tilden established a research station in British Columbia which lasted only until 1906. When Tilden became an assistant Professor in 1903, she was the first female scientist employed by the University of Minnesota. In 1910, despite not having a doctorate, Tilden was promoted to full professor.
Ferocactus chrysacanthus, commonly known as the Cedros barrel cactus, is an endangered species of cactus endemic to the islands of Cedros and West San Benito off the Pacific coast of Baja California, Mexico.
William Albert Setchell was an American botanist and marine phycologist who taught at the University of California, Berkeley, where he headed the Botany Department. Among his publications are the Phycotheca Boreali-Americana, a multi-volume specimen collection of dried algae, and the Algae of Northwestern America, a reference work.
Veli Johannes Paavo Bartholomeus Räsänen was a Finnish lichenologist.
Exsiccata is a work with "published, uniform, numbered set[s] of preserved specimens distributed with printed labels". Typically, exsiccatae are numbered collections of dried herbarium specimens or preserved biological samples published in several duplicate sets with a common theme or title, such as Lichenes Helvetici. Exsiccatae are regarded as scientific contributions of the editor(s) with characteristics from the library world and features from the herbarium world. Exsiccatae works represent a special method of scholarly communication. The text in the printed matters/published booklets is basically a list of labels (schedae) with information on each single numbered exsiccatal unit. Extensions of the concept occur.
Myrtillocactus cochal, the cochal or candelabra cactus, is a species of flowering plant in the family Cactaceae, native to the Baja California peninsula. Individuals can reach 3 m (10 ft), and are hardy to USDA zone 9b.
William Gardiner (1808-1852) was a Scottish umbrella maker, poet, and bryologist.
IndExs – Index of Exsiccatae is an online biological database that plays a pivotal role in documenting more than 2,200 historical and ongoing series of exsiccatae and exsiccata-like works. Managed by the Botanische Staatssammlung München in München, IndExs serves as a comprehensive data repository for these series, providing detailed titles with information on the more than 1,300 editors, bibliographic information, exsiccatal numbers, publication timespans, ranges, information on preceding and superseding series and publishers. Exsiccatae, organised series of biological specimens distributed among biological collections, are essential resources found in major herbaria worldwide. Open access to the general information on exsiccatae facilitates global scientific engagement and research.
