Casimir Christoph Schmidel
Casimir Christoph Schmidel (born 21 November 1718 in Bayreuth, Germany, died 18 December 1792 in Ansbach, Germany) was a naturalist of the 18th century who researched in botany and mineralogy. Among genera he named are the flowering plant genera ''Penstemon'' and '' Proboscidea'' and the fern genus '' Thelypteris''. Among species he described are the red alga ''Dilsea carnosa ''Dilsea carnosa'', commonly known as the poor man's weather glass or the sea belt, is a species of red algae in the Dumontiaceae family of the order Gigartinales.

Penstemon
''Penstemon'' , the beardtongues, is a large genus of roughly 250 species of flowering plants native mostly to the Nearctic, but with a few species also found in the North American portion of the Neotropics. It is the largest genus of flowering plants endemic to North America. Formerly placed in the family Scrophulariaceae by the Cronquist system, new genetic research has placed it in the vastly expanded family Plantaginaceae. They have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue. Most penstemons are deciduous or semi-evergreen perennials, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proboscidea (plant)
''Proboscidea'' is a genus of flowering plant in the family Martyniaceae, some of whose species are known as devil's claw, devil's horn, ram's horn, or unicorn plant. The plants produce long, hooked seed pods. The hooks catch on the feet of animals, and as the animals walk, the pods are ground or crushed open, dispersing the seeds. The name devil's claw is shared with the South African plant '' Harpagophytum procumbens''. Uses The fruits of all species are edible before they ripen and become woody. They can be steamed and eaten much like okra. Some species (particularly ''P. parviflora'') are used in basket weaving by the Tohono O'odham who have selected for varieties with longer "claws." The Chemehuevi also use devil's claw pods in basketry. The Hia C-eḍ Oʼodham and the Tohono O'odham eat the seeds, which provided an important source of dietary oils. ''P.'' ''parviflora'' was also used as a remedy for rheumatism. Species Species include: * ''Proboscidea althaeifolia'' - ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thelypteris
''Thelypteris'' (maiden ferns) is a genus of ferns in the subfamily Thelypteridoideae, family Thelypteridaceae, order Polypodiales. Two radically different circumscriptions of the genus are in use . In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the genus is a very small one with about two species. In other approaches, the genus is the only one in the subfamily Thelypteridoideae, and so includes between 875 and 1083 species. The genus name is from Greek ''thēlys'' "female" and ''pteris'' "fern". However, "female fern" usually refers to the common lady-fern. Taxonomy At one time, all thelypterioid ferns were included in the genus ''Dryopteris'' because of the sorus shape. However, there are a great many differences between the groups, and these plants are now segregated in their own family. Some researchers include the entire family Thelypteridaceae in the genus ''Thelypteris''. An intermediate position is to place the bulk in ''Thelypteris'' (correspo ...

Dilsea Carnosa
''Dilsea carnosa'', commonly known as the poor man's weather glass or the sea belt, is a species of red algae in the Dumontiaceae family of the order Gigartinales. Taxonomy The species was first described scientifically by Schmidel in 1794, under the name ''Fucus carnosus''. The German botanist Otto Kuntze transferred the species to '' Dilsea'' in 1898. Description This large alga is dark red, flattened and somewhat leathery. It may be 30 cm or more long and 15 cm wide. It is usually not branched but may split. It grows from a small discoid base.Bunker, F.StP. D., Brodie, J.A., Maggs, C.A. and Bunker, Anne R. 2017. ''Seaweeds of Britain and Ireland.'' Second Edition, Wild Nature Press, Plymouth, UK.

18th-century German Botanists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.
