Sphaerocarpos Texanus
''Sphaerocarpos texanus'', the Texas balloonwort, is a species of liverwort in the Sphaerocarpaceae family, found in the Americas, northern Africa and Europe. Description ''Sphaerocarpos texanus'' are small, thalloid, dioecious liverworts. The species is sexually dimorphic, with male plants usually 3–5 mm in diameter, females up to 12 mm in diameter. Both male (bearing antheridia) and female (bearing archegonia) plants are bright green, with the thallus branching up to several times. The plant is a winter annual, appearing in autumn and dying in spring. Notably, the spores occur in sets of four, called tetrads. Unlike most other species of liverwort, the spores stay in these tetrads until they germinate. Habitat The plant is found on flat, lightly shaded soil. Usually by roadsides. Distribution ''Sphaerocarpos texanus'' has a wide range, probably the widest of any species in its genus. It has been found on several continents, in the United States Th ...

Sporophyte
A sporophyte () is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores. This stage alternates with a multicellular haploid gametophyte phase. Life cycle The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase. In the seed plants, the largest groups of which are the gymnosperms and flowering plants (angiosperms), the sporophyte phase is more prominent than the gametophyte, and is the familiar green plant with its roots, stem, leaves and cones or flowers. In flowering plants the gametophytes are very reduced in size, and are represented by the germinated pollen and the embryo sac. The sporophyte produces spores (hence ...

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Flora Of France
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Great Britain
The flora of Great Britain and Ireland is one of the best documented in the world. There are 1390 native species and over 1100 well-established non-natives documented on the islands. A bibliographic database of the species is compiled by the Botanical Society of Britain and Ireland. Because of the size of the list, it is spread across multiple pages. * Part 1 covers ferns and allies ( Lycopodiopsida, Equisetopsida and Pteridopsida) * Part 2 covers the conifers (Pinopsida) The remaining parts cover the flowering plants (Magnoliopsida): * Part 3, covering a group of dicotyledon families (Lauraceae to Salicaceae) * Part 4, covering another group of dicotyledon families (Brassicaceae to Saxifragaceae) * Part 5, covering the dicotyledon family Rosaceae Rosaceae (), the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.

Flora Of Uruguay
The flora of Uruguay consists of 2,500 species distributed among 150 native and foreign biological families. Approximately 80% of Uruguay is prairie, with grasses predominating. Uruguay is primarily a grass-growing land, with vegetation that is essentially a continuation of the Argentine Pampas. Forest areas are relatively small. Trees grow in bunches. Forested areas are much smaller than in the pampas, but contain a mix of hardwoods and softwoods, while eucalyptus were imported from Australia. "Ceibo", or '' Erythrina cristagalli'', is the national flower. Herbs Uruguay contains many herbs, ferns, and flowers. Riverine forests Natural forests in Uruguay mainly grow near rivers in the countryside. The native forests are composed of more than 500 native species, including palms. The most abundant are "sauce criollo" ('' Salix humboldtiana''), "sarandí colorado" ('' Cephalanthus glabratus''), "sarandí blanco" ('' Phyllanthus sellowianus'') and "mataojos" ('' Pouteria sal ...

Flora Of The United States
The native flora of the United States includes about 17,000 species of vascular plants, plus tens of thousands of additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses. About 3,800 additional non-native species of vascular plants are recorded as established outside of cultivation in the U.S., as well as a much smaller number of non-native non-vascular plants and plant relatives. The United States possesses one of the most diverse temperate floras in the world, comparable only to that of China. Several biogeographic factors contribute to the richness and diversity of the U.S. flora. While most of the United States has a temperate climate, Alaska has vast arctic areas, the southern part of Florida is tropical, as well as Hawaii (including high mountains), and the U.S. territories in the Caribbean and the Pacific, and alpine summits are present on many western mountains, as well as a few in the Northeast.

Sphaerocarpales
Sphaerocarpales is an order of plants within the liverworts. Approximately twenty species are in this order which is sub-divided into four families: Monocarpaceae, Sphaerocarpaceae and Riellaceae, as well as the extinct family Naiaditaceae.
