He described several of the major conifers discovered in the period, including first descriptions of coast redwood (''Taxodium sempervirens'' D. Don; now ''Sequoia sempervirens'' (D. Don) Endl.), Bristlecone Fir (''Pinus bracteata'' D. Don, now ''Abies bracteata'' (D. Don) A. Poit.), Grand Fir (''Pinus grandis'' Douglas ex D. Don; now ''Abies grandis'' (Douglas ex D.

Hans Melchior
Hans Melchior (5 August 1894 – 12 March 1984) was a German botanist. Melchior was born in Berlin. He studied botany at Berlin University, became assistant to G. Haberlandt at the Institute for plant physiology and took his doctor's degree with him in 1920. Later he was assistant at the Botanical Museum and Herbarium, Berlin-Dahlem, on 1 October 1920, the beginning of an uninterrupted career at that institute in which he went through all the ranks, ending as interim director (1958–1959), and having been professor of botany from 1940 teaching at Technical University of Berlin. Among his many contributions to taxonomy are his treatments of the Medusagynaceae, Theaceae, Violaceae, and Canellaceae for the second edition of the '' Die Natürlichen Pflanzenfamilien'' of Engler & K. Prantl, the publication as editor with E. Werdermann, of ed. 12 (1954-1964) of Engler's " Syllabus der Pflanzenfamilien", and, as a last major contribution (with Hans Kastner) of Gewurze (19 ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, 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 common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simple Leaf
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper ( adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light ...

Tecoma
''Tecoma'' is a genus of 14 species of shrubs or small trees in the trumpet vine family, Bignoniaceae. Twelve species are from the Americas, while the other two species are African. The American species range from the extreme southern United States through Central America and the Antilles south through Andean South America to northern Argentina. The generic name is derived from the Nahuatl Nahuatl (; ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about Nahua peoples, most of whom live mainly in Central Mexico and have small ... word ''tecomaxochitl'', which was applied by the indigenous peoples of Mexico to plants with tubular flowers.

Flora Of South America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...
