G S Perrottet
G, or g, is the seventh Letter (alphabet), letter of the Latin alphabet, used in the English alphabet, modern English alphabet, the alphabets of other western Languages of Europe, European languages, and others worldwide. Its name in English is English alphabet#Letter names, ''gee'' (pronounced ), plural ''gees''. The Letter case, lowercase version can be written in two forms: the single-storey (sometimes "opentail") and the double-storey (sometimes "looptail") . The former is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children. History The evolution of the Latin alphabet's G can be traced back to the Latin alphabet's predecessor, the Greek alphabet. The voiced velar stop was represented by the third letter of the Greek alphabet, Gamma, gamma (Γ), which was later adopted by the Etruscan language. Latin then borrowed this "rounded form" of gamma, C, to represent the same sound in words such as ''recei'', which was likely a ...

He became an ''aide-naturaliste'' to Adrien-Henri de Jussieu (1797–1853), who served as the chair of rural botany. It was during this time that he began to study plants brought back by various travelers like those of Victor Jacquemont (1801–1832) from Asia. Decaisne used applied research, most notably on the agronomy of the madder, the yam and the ramie. He was also interested in algae.

Horticulturists
Horticulture (from ) is the art and science of growing fruits, vegetables, flowers, trees, shrubs and ornamental plants. Horticulture is commonly associated with the more professional and technical aspects of plant cultivation on a smaller and more controlled scale than agronomy. There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges -- each requiring highly specialized skills and knowledge on the part of the horticulturist. Typically, horticulture is characterized as the ornamental, small-scale and non-industrial cultivation of plants; horticulture is distinct from gardening by its emphasis on scientific methods, plant breeding, and technical cultivation practices, while gardening, even at a professional level, tends to ...

European And American Voyages Of Scientific Exploration
The era of European and American voyages of scientific exploration followed the Age of Discovery and were inspired by a new confidence in science and reason that arose in the Age of Enlightenment. Maritime expeditions in the Age of Discovery were a means of expanding colonial empires, establishing new trade routes and extending diplomatic and trade relations to new territories, but with the Age of Enlightenment, Enlightenment scientific curiosity became a new motive for exploration to add to the commercial and political ambitions of the past. See also List of Arctic expeditions and List of Antarctic expeditions. Maritime exploration in the Age of Discovery From the early 15th century to the early 17th century the Age of Discovery had, through Portuguese seafarers, and later, Spanish, Dutch, French and English, opened up southern Africa, the Americas (New World), Asia and Oceania to European eyes: Bartholomew Dias had sailed around the Cape of southern Africa in search of a trade ...

List Of Gardener-botanist Explorers Of The Enlightenment
The Age of Discovery, also known as the Age of Exploration, was a period in history starting in the early 15th century and continuing into the early 17th century during which Europeans engaged in intensive exploration of the world, establishing direct contacts with Africa, the Americas, Asia and Oceania and mapping the planet. Scientific matters at this time were of little interest as exploration was mostly commercially and politically motivated. Captivated by the lure of gold, silver and spices, Portuguese and Spanish sailors pioneered new trade routes to the Indies. The Age of Discovery was followed in the late 18th and early 19th centuries by the Age of Enlightenment (also known as the Age of Reason) which was an era of scientific awakening with a strong belief in the power of reason as the primary source of legitimacy and authority. Scientific fervour and intellectual curiosity at this time resulted in many voyages of scientific exploration around the world facilitated by te ...
