Édouard Placide Duchassaing De Fontbressin
Édouard Placide Duchassaing de Fontbressin (1819 in Moule, Guadeloupe – 1873 in PĂ©rigueux) was a French naturalist. He is noted for his work in botany and spongiology. A native of Guadeloupe, he studied zoology, geology and medicine in Paris. Afterwards, he returned to Guadeloupe as a physician, spending his free time conducting research of the island's flora. Subsequently, he visited several other islands of the Antilles, eventually relocating as a physician to Santa Marta, Panama (1848), from where he studied the natural history of the isthmus, sending his plant specimens to Wilhelm Gerhard Walpers, a botanist in Berlin (these specimens later became the property of August Grisebach).JSTOR Global Plants biography Around 1850, he obtained a medical degree at |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Demosponge
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ove ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Microcionidae
Microcionidae is a family of marine demosponges. Subdivisions The following genera are recognized within the family Microcionidae: * Subfamily Microcioninae Carter 1875 ** ''Clathria'' Schmidt, 1862 ** '' Echinochalina'' Thiele, 1903 ** ''Holopsamma'' Carter, 1885 ** ''Pandaros'' Duchassaing & Michelotti, 1864 * Subfamily Ophlitaspongiinae de Laubenfels, 1936 ** ''Antho'' Gray, 1867 ** ''Artemisina'' Vosmaer, 1885 ** ''Echinoclathria'' Carter, 1885 ** ''Ophlitaspongia ''Ophlitaspongia'' is a genus of demosponges belonging to the family Microcionidae.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
