Hipólito Ruiz López
Hipólito Ruiz López (August 8, 1754 in Belorado, Burgos, Spain – 1816 in Madrid), or Hipólito Ruiz, was a Spanish botanist known for researching the floras of Peru and Chile during an expedition under Charles III of Spain, Carlos III from 1777 to 1788. During the reign of Carlos III, three major botanical expeditions were sent to the New World; Ruiz and José Antonio Pavón Jiménez were the botanists for the first of these expeditions, to Peru and Chile. Background After studying Latin with an uncle who was a priest, at the age of 14 Ruiz López went to Madrid to study logic, physics, chemistry and pharmacology. He also studied botany at the Migas Calientes Botanical Gardens (now the Real Jardín Botánico de Madrid), under the supervision of Casimiro Gómez Ortega (1741–1818) and Antonio Palau Verdera (1734–1793). Ruiz had not yet completed his pharmacology studies when he was named the head botanist of the expedition. The French physician Joseph Dombey was named as ...

José Antonio Pavón Jiménez
José Antonio Pavón Jiménez or José Antonio Pavón (April 22, 1754 in Casatejada, Cáceres, Spain – 1840 in Madrid) was a Spanish botanist known for researching the flora of Peru and Chile. Biography During the reign of Charles III of Spain, three major botanical expeditions were sent to the New World; Pavón and Hipólito Ruiz López were the botanists for the first of these expeditions, to Peru and Chile from 1777 to 1788. The genus '' Pavonia'' was named in his honor by his contemporary, Spanish botanist Antonio José Cavanilles — plants with the specific epithet of ''pavonii'' also commemorate his name.Etymological Dictionary of Grasses

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ...

Francoaceae
The Francoaceae are a small family of flowering plants in the order Geraniales, including the genera '' Francoa'', commonly known as bridal wreaths. The Francoaceae are recognized as a family under various classification schemes. Under the 2009 APG III system the Francoaceae were included within the Melianthaceae. In the 2016 APG IV system the Francoaceae are again recognized as a family, with Melianthaceae included in the circumscription of Francoaceae. Genera , Plants of the World Online included the following genera in Francoaceae: *'' Balbisia'' Cav. *'' Bersama'' Fresen. *'' Dimorphopetalum'' Bertero *'' Francoa'' Cav. *'' Greyia'' Hook. & Harv. *'' Melianthus'' L. *'' Rhynchotheca'' Ruiz & Pav. *'' Viviania'' Cav. Formerly included genera: *''Tetilla'' DC. – now in Saxifragaceae Saxifragaceae is a family of Herbaceous plant, herbaceous Perennial plant, perennial flowering plants, within the core eudicot Order (biology), order Saxifragales.

Monotypic Geraniales Genera
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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Taxa Named By José Antonio Pavón Jiménez
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ...
