Awns are characteristic of many grass es Poaceae , where they extend from the lemma botany lemma s of the floret s. They often make up the hairy appearance of the grass synflorescence. Awns may be long several centimeters or short, straight or curved, single or multiple per floret. Some genera are named after their awns, such as the three awn s Aristida . In some species, the awns can contribute significantly to photosynthesis, for example barley . The awns of wild emmer wheat spikelets effectively self cultivate by propelling themselves mechanically into soils. During a period of increased humidity during the night, the awns of the spikelet become erect and draw together, and in the process push the grain into the soil. During the daytime the humidity drops and the awns slacken back again however, fine silica hairs on the awns act as hooks in the soil and prevent the spikelets from reversing back out again. During the course of alternating stages of daytime and nighttime humidity, the awns pumping movements, which resemble a swimming frog kick , drill the spikelet as much as an inch into the soil. ref cite journal last Elbaum first Rivka authorlink coauthors Zaltzman, Liron Burgert, Ingo Fratzl, Peter year 2007 month title The Role of Wheat Awns in the Seed Dispersal Unit journal Science journal Science volume 316 issue 5826 pages 884&ndash 886 doi 10.1126 science.1140097 url accessdate quote pmid 17495170 ref References reflist Wiktionary awn DEFAULTSORT Awn Botany Category Plant morphology Botany stub cs Osina de Granne eo Aristo fr Barbe botanique ja la Arista nl Kafnaald gras nn Agn pt Aristo ru fi Vihne ... more details

File Ms 744 obs natiabouani 02.jpg thumb 225px Sudanian savanna with bunchgrass tufts of Andropogon gayanus , Pama reserve, Burkina Faso . The Sudanian Savanna is a broad belt of tropical and subtropical grasslands, savannas, and shrublands tropical savanna that runs east and west across the Africa n continent, from the Atlantic Ocean in the west to the Ethiopian Highlands in the east. The Sahel , a belt of drier grasslands and acacia savannas, lies to the north, between the Sudanian Savanna and the Sahara Desert . To the south the forest savanna mosaic is a transition zone between the Sudanian Savanna and the Guinean moist forests and Congolian forests that lie nearer the equator. Ecoregion The World Wide Fund for Nature divides the Sudanian Savanna into two ecoregion s, separated by the Cameroon Highlands . The West Sudanian Savanna runs from the Atlantic Ocean to eastern Nigeria, and the East Sudanian Savanna runs from the Cameroon Highlands east to the Ethiopian Highlands . Physiographic province The Sudanian Savanna is one of the three distinct physiographic provinces of the larger African massive division. Physiography divides this province into three distinct physiographic sections, the Niger River Niger Basin , the Lake Chad Lake Chad Basin , and the Nile River Middle Nile Basin . Vegetation The Sudanian Savanna is characterized by the coexistence of trees and grasses. Dominant tree species are often belonging to the Combretaceae and Caesalpinioideae , some Acacia species are also important. The dominant grass species are usually Andropogoneae , especially the genera Andropogon and Hyparrhenia , on shallow soils also Loudetia and Aristida . Much of the Sudanian Savanna region is used in the form of parklands, where useful trees, such as shea , baobab , Parkia biglobosa locust bean tree and others are spared from cutting, while sorghum , maize , millet or other crops are cultivated beneath.
