History of Animals (Greek: Τῶν περὶ τὰ ζῷα ἱστοριῶν , Ton peri ta zoa historion, "Inquiries on Animals"; Latin: "Historia Animālium" "History of Animals") is one of the major texts on biology by the ancient Greek philosopher Aristotle, who had studied at Plato's Academy in Athens.
 It was written in the fourth century BC; Aristotle died in 322 BC.
Leonard Plukenet (1641–1706) was an English botanist, Royal Professor of Botany and gardener to Queen Mary.
 Plukenet published "Phytographia" (London, 1691–1692) in four parts in which he described and illustrated rare exotic plants.
 It is a copiously illustrated work of more than 2 700 figures and is frequently cited in books and papers from the 17th century to the present.
 He collaborated with John Ray in the second volume of "Historia Plantarum" (London, 1686–1704).
Historia Plantarum (also called Conradi Gesneri Historia Plantarum) is an extensive botanical encyclopedia by the Swiss natural scientist, Conrad Gessner (1516 – 1565).
 Although compiled between 1555 and 1565, it was not published till after 1750, since he died of the plague, prior to its completion.
 To complete the work, he amassed a collection of some 1,500 drawings of plants, most of which were his own work.
 The scale and scientific rigour were unusual for the time, and Gessner was a skilled artist, producing detailed drawings of specific plant parts that illustrated their characteristics, with extensive marginal notation discussing their growth form and habitation.
Theophrastus's Enquiry into Plants or Historia Plantarum (Greek: Περὶ φυτῶν ἱστορία , "Peri phyton historia") was, along with his mentor Aristotle's "History of Animals", Pliny the Elder's "Natural History" and Dioscorides's "De Materia Medica", one of the most important books of natural history written in ancient times, and like them it was influential in the Renaissance.
 Theophrastus looks at plant structure, reproduction and growth; the varieties of plant around the world; wood; wild and cultivated plants; and their uses.
 Book 9 in particular, on the medicinal uses of plants, is one of the first herbals, describing juices, gums and resins extracted from plants, and how to gather them.
Historia Plantarum (Latin: "History of/Treatise on Plants") has been used as all or part of the name of several books, which include:
Martynia is a monotypic genus in the Martyniaceae consisting of a single species, Martynia annua, commonly known as the cat's claw, and is endemic to Mexico.
 It is a popular material for basket making among Native American tribes in the Southwest.
 The genus and species were first validly described by Carl Linnaeus in his 1753 publication "Species Plantarum".
 It was first collected, however, by the Scottish naval surgeon William Houstoun near Veracruz, Mexico.
 Houstoun sent seeds of this new plant to Philip Miller, chief gardener at the Chelsea Physic Garden, in 1731.
 Houstoun took the opportunity to name the plant "Martynia" in honor of a professor of botany at Cambridge, John Martyn.
 The plant was first seen in print in Martyn's famous work "Historia Plantarum Rariorum", with a full description and illustration.
 In this pre-Linnaean nomenclature era, Martyn gave the species the following descriptive name: "Martynia annua villosa et viscosa, folio subrotundo, flore magno rubro".
Historia Plantarum ("The History of Plants") is a botany book by John Ray, published in 1686.
Mentor High School is a public high school located in Mentor, Ohio.
 It is the only high school in the Mentor Exempted Village School District (informally, "Mentor Schools").
 At one time, it was the largest high school in Ohio based on single building enrollment.
 For the 2008–2009 school year, it shifted from a three-year school (grades 10–12) to a four-year high school (grades 9–12), serving 3,200 students.
 Mentor High School educates students from Mentor, Mentor-on-the-Lake, and parts of Kirtland Hills and Concord Township in Lake County, Ohio.
 All three middle schools from the Mentor Exempted Village School district, including Memorial Middle School, Shore Middle School, and Ridge Middle School, feed into Mentor High School.
Georg Joseph Kamel (] ; Latin: "Georgius Josephus Camellus"; Czech: "Jiří Josef Kamel", Spanish: "Jorge Camel"; 21 April 1661 – 2 May 1706) was a Jesuit missionary, pharmacist and naturalist known for producing first comprehensive accounts of the Philippine flora and fauna and for introducing Philippine nature to the European learned world.
 A number of Kamel's treatises were published in the Philosophical Transactions, while his descriptions of Philippine flora appeared as an appendix to the third volume of John Ray's Historia Plantarum.
Giovanni de Matociis (born probably in the second half of the 13th Century and died in December 1337), commonly called Giovanni Mansionario from his administrative office in the cathedral of Verona, was an early Italian humanist, a forerunner of Petrarch.
 In about 1311 he was appointed as "mansionario", a role for a person in minor orders variously described by sources as a sacristan or recipient of a minor benefice from legacies: Vivaldi held such a position some four centuries later.
 Giovanni was also a notary.
 From this time he began work amassing his "Historia Imperialis" ("Imperial History") a series of emperors' biographies, beginning with Augustus, in which his antiquarian bent and classical studies amended many misconceptions of ancient Roman history; Though he depended on Isidore's "Etymologiae" to a degree that would have been considered naive a century later, and on the "Historia Augusta", deprecated nowadays, his marginal drawings of Roman coins show that numismatics had been brought to the historian's aid perhaps for the first time in this work.
 Roberto Weiss has observed that "during the early Trecento [14th century] such a work as the "Historia Imperialis" could have been produced only in Verona", with the unrivalled library holdings of its cathedral chapter.
 His Latin has been described as "nondescript, unadorned".
