Cyperus Polystachyos
''Cyperus polystachyos'', also known as ''Pycreus polystachyos'', and also called manyspike flatsedge in the US, or bunchy sedge, coast flatsedge, many-spiked sedge or Texas sedge in Australia, is a herbaceous species in the family Cyperaceae, widespread in tropical and subtropical areas around the world, sometimes extending its range into temperate regions. Description The rhizomatous, perennial or annual grass-like sedge typically grows to a height of . It blooms between summer and winter and produces green-brown flowers. The stems are rigid with a thickness of . Stems are glabrous with a triangular cross-section. The leaves are very narrow, around with a grass-like appearance and are often tufted at the base of the plant. The seed-head is an irregular cluster formation at the tip of the stem with brown spikes that have three to six green leafy bracts underneath. Distribution It is common in the Neotropics as a weed in grass lawns. In Australia the species is widespread in wa ...

Christen Friis Rottbøll
Christen Friis Rottbøll (3 March 1727, at Hørbygård, Denmark – 15 June 1797, in Copenhagen) was a Danish physician and botanist: He was a pupil of Carolus Linnaeus. Early life Rottbøll was born on the Hørbygaard estate at Holbæk, the son of Christen Michelsen Rottbøll (died 1729) and Margrethe Cathrine Friis. His father was the manager of the estate but died in 1729. His mother was married second time to manager of Hagestedgaard Ole Nielsen Faxøe. Education and career Rottbøll studied at the University of Copenhagen, first theology, then medicine, in which he took his doctorate degree in 1755 (''De morbis deuteropathicis seu Sympathier''). He then travelled abroad 1757–1761 to further his studies of medicine, and to study chemistry and botany – the latter subject at Uppsala University with Linnaeus. From 1761, he was executive at the Botanic Garden in Copenhagen, and succeeded Georg Christian Oeder as its director in 1770. He was appointed professor at t ...

Flora Of Australia
The flora of Australia comprises a vast assemblage of plant species estimated to over 30,000 vascular and 14,000 non-vascular plants, 250,000 species of fungi and over 3,000 lichens. The flora has strong affinities with the flora of Gondwana, and below the family level has a highly endemic angiosperm flora whose diversity was shaped by the effects of continental drift and climate change since the Cretaceous. Prominent features of the Australian flora are adaptations to aridity and fire which include scleromorphy and serotiny. These adaptations are common in species from the large and well-known families Proteaceae (''Banksia''), Myrtaceae (''Eucalyptus'' - gum trees), and Fabaceae (''Acacia'' - wattle). The arrival of humans around 50,000 years ago and the settlement by Europeans from 1788, has had a significant impact on the flora. The use of fire-stick farming by Aboriginal people led to significant changes in the distribution of plant species over time, and the large-sca ...

Flora Of Madagascar
The flora of Madagascar consists of more than 12,000 species of plants, as well as a poorly known number of fungi and algae. Around 83% of Madagascar's vascular plants are found only on the island. These endemics include five plant families, 85% of the over 900 orchid species, around 200 species of palms, and such emblematic species as the traveller's tree, six species of baobab and the Madagascar periwinkle. The high degree of endemism is due to Madagascar's long isolation following its separation from the African and Indian landmasses in the Mesozoic, 150–160 and 84–91 million years ago, respectively. However, few plant lineages remain from the ancient Gondwanan flora; most extant plant groups immigrated via across-ocean dispersal well after continental break-up. After its continental separation, Madagascar probably experienced a dry period, and tropical rainforest expanded only later in the Oligocene to Miocene when rainfall increased. Today, humid forests, inc ...

Flora Of Asia
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 ...

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected tha the series would conclude in 2017. Twenty-nine of the volumes have been published as of 2022. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treatme ...

Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide an alternative food source for ...
