Friedrich Alefeld
Friedrich Georg Christoph Alefeld (21 October 1820 – 28 April 1872) was a botanist, author, and medical practitioner. Born in Weiterstadt-Gräfenhausen, Grand Duchy of Hesse; he described a number of plant species in his published works, taking a particular interest in legumes and Malvaceae. He attempted to give a systematic treatment of German crops in one work, in addition to writing treatises on herbal baths and cultivated plants of potential usefulness. A number of his essays appeared in the botanical literature of the day. His works include: * Articles in ''Oesterreichische Botanische Zeitschrift'' (Oesterr. Bot. Z.) The Austrian Botanical Magazine. * ''Landwirthschaftliche flora: oder Die nutzbaren kultivirten Garten- und Feldgewächse Mitteleuropa's in allen ihren wilden und Kulturvarietäten für Landwirthe, Gärtner, Gartenfreunde und Botaniker insbesondere für landwirthschaftliche Lehranstalten''. Berlin, Wiegandt & Hempel, 1866. * ''Grundzüge der Phytobalneologie; o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvaceae
Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include okra, cotton, cacao and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The largest genera in terms of number of species include ''Hibiscus'' (300 species), ''Sterculia'' (250 species), ''Dombeya'' (250 species), '' Pavonia'' (200 species) and '' Sida'' (200 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae '' sensu stricto'' comprise a very homogeneous and cladistically monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies have shown the commonly recognised families Bombacaceae, Tiliaceae, and Sterculiaceae, which have always been considered closely allie ...

Puccinia Malvacearum
''Puccinia malvacearum'' on '' Pelargonium'' geranium ''Puccinia malvacearum'', also known as hollyhock or mallow rust, is a species within the genus ''Puccinia'' known for attacking members of the family Malvaceae. An autoecious pathogen, it can complete its life cycle using a single host. Plants affected by the rust include ''Abutilon'', ''Alcea'' (Hollyhock), ''Hibiscus'', ''Lavatera'', ''Malva'', ''Malvastrum'' and ''Sphaeralcea''. Suggested control measures include sanitation (removal or destruction of affected plants or plant portions) or treatment with fungicides.

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Alcea
''Alcea'' is a genus of over 80 species of flowering plants in the mallow family Malvaceae, commonly known as the hollyhocks. They are native to Asia and Europe. The single species of hollyhock from the Americas, the streambank wild hollyhock, belongs to a different genus. Description Hollyhocks are annual, biennial, or perennial plants usually taking an erect, unbranched form. The herbage usually has a coating of star-shaped hairs. The leaf blades are often lobed or toothed, and are borne on long petioles. The flowers may be solitary or arranged in fascicles or racemes. The notched petals are usually over three centimeters wide and may be pink, white, purple, or yellow. The fruit is a schizocarp, a dry disc divided into over 15 sections that contain seeds. Species The following species are accepted: *''Alcea abchazica'' Iljin *''Alcea acaulis'' (Cav.) Alef. *''Alcea afghanica'' I.Riedl *'' Alcea antoninae'' Iljin *''Alcea apterocarpa'' (Fenzl) Boiss. *''Alcea arbelensis'' ...

Flora Of Ukraine
Flora is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. 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 Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
