Phymosia Umbellata
''Phymosia umbellata'' is a species of flowering plant in the family Malvaceae. It is native to Mexico and is cultivated as an ornamental plant. This tropical evergreen shrub grows to in height, with cup shaped scarlet flowers produced mainly in summer.

Thomas Henry Kearney
Thomas Henry Kearney (27 June 1874 – 19 October 1956) was an American botanist and agronomist known for his work on cotton and date palm breeding, plant taxonomy, and the flora of Arizona. Kearney was born on 27 June 1874 in Cincinnati, Ohio. He enrolled in the University of Tennessee in 1889, and began working for the U.S. Department of Agriculture in 1894, where he would work for the next 50 years. Kearney published a revision of North American ''Calamagrostis'' in 1898, describing 23 new species or varieties. From 1898 to 1900 Kearney participated in the Harriman Alaska Expedition. In the early 1900s Kearney traveled throughout North Africa to study crops such as dates and cotton in arid and alkali soils, and began a decades-long period of cotton-breeding research in Arizona. Kearney served as President of the Botanical Society of Washington in 1917. From 1920 to 1944 he also studied the taxonomy and distributions of plants of Arizona. A major collaborator during this peri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...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 ...

Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Temperate Climate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Malveae
Malveae is a Tribe (biology), tribe of flowering plants in the Malva, mallow Family (biology), family Malvaceae, Family (biology), subfamily Malvoideae. The tribe Circumscription (taxonomy), circumscribes approximately 70 genera and 1040 species and has the greatest species diversity out the three tribes that make up Malvoideae (followed by Hibisceae and then Gossypieae). The flowers of Malveae are five-Merosity, merous with a characteristic Stamen, staminal column, a trait found throughout Malvoideae. Although there are not many economically important species within Malveae, the tribe includes ''Althaea officinalis'', otherwise known as the marsh-mallow. The fruits of Malveae are generally schizocarpic, although some are functionally Capsule (fruit), capsular. The tribe generally includes herbaceous plants, although ''Robinsonella'' are trees. The tribe is a well supported Monophyly, monophyletic group, supported by chloroplast and ribosomal DNA. Within Malvoideae, Malveae forms a ...
