Cistanche
''Cistanche'' is a worldwide genus of holoparasitic desert plants in the family Orobanchaceae. They lack chlorophyll and obtain nutrients and water from the host plants whose roots they parasitize. They are often known as desert hyacinths. Taxonomy There are between 20 and 30 species of ''Cistanche''. The most comprehensive description of the genus was published in 1930. The taxonomy is difficult because important features of the flowers are often poorly preserved after drying. The plants are found from the Mediterranean region, North Africa, Middle East through to China. The species of ''Cistanche'' are parasitic plants that connect to the conductive system of a host, extracting water and nutrients from the roots of the host plant. Growth They typically grow in desert or sand dune areas Growing in arid regions, where their flower spikes that emerge from bare ground are the only evidence of the presence of the plants. They do not have leaves and do not perform photosynthesis. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orobanchaceae Genera
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera (e.g., ''Pedicularis'', ''Rhinanthus'', ''Striga'') were formerly included in the family Scrophulariaceae ''sensu lato''. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing '' Orobanche major'' and relatives, but neither ''Paulownia tomentosa'' nor ''Phryma leptostachya'' nor '' Mazus japonicus''. The Orobanchaceae are annual herbs or perennial herbs or shrubs, and most (all except ''Lindenbergia'', ''Rehmannia'' and ''Triaenophora'') are parasitic on the roots of other plants—either holoparasitic or hemiparasitic (fully or partly parasitic). The holoparasitic species lack chlorophyll and therefore cannot perform photosynthesis. Description Orobanchaceae is the largest of the 20–28 dicot f ...

Haloxylon Ammodendron
''Haloxylon ammodendron'', the saxaul, black saxaul, sometimes sacsaoul or saksaul ( rus, саксау́л, r=saksaúl, which is from kk, сексеуіл, r=seksewil), is a plant belonging to the family Amaranthaceae. Description The saxaul ranges in size from a large shrub to a small tree, , rarely tall. It has a brown trunk up to in diameter. The wood is heavy and coarse and the bark is spongy and water-soaked. The branches of the current year are green; older branches are brown, or gray to white. The leaves are reduced to very small cusp-like scales, so that the plant appears nearly leafless. The infloresences consist of short lateral shoots borne on stems of the previous year. The flowers are bisexual or male, very small, as long as or shorter than the bracteoles. The flowering period is from March to April. In fruit, the perianth segments develop spreading pale brown or white wings. The diameter of the winged fruit is about . The seed is in diameter. The fruiting peri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chlorophyll
Chlorophyll (also chlorophyl) is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words , ("pale green") and , ("leaf"). Chlorophyll allow plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll ''a'' and ''b''. History Chlorophyll was first isolated and named by Joseph Bienaimé Caventou and Pierre Joseph Pelletier in 1817. The presence of magnesium in chlorophyll was discovered in 1906, and was that element's first detection in living tissue. After initial work done by German chemi ...

Parasitic Plant
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like ''Striga'' or ''Rhinanthus'' connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like ''Cuscuta'' and some members of ''Orobanche'' connect to both the xylem and phloem of the host. This provides them with the ability to extract water and nutrients from the host. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host (root or stem), the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taklimakan
The Taklimakan or Taklamakan Desert (; zh, s=塔克拉玛干沙漠, p=Tǎkèlāmǎgān Shāmò, Xiao'erjing: , dng, Такәламаган Шамә; ug, تەكلىماكان قۇملۇقى, Täklimakan qumluqi; also spelled Taklimakan and Teklimakan) is a desert in Southwestern Xinjiang in Northwest China. It is bounded by the Kunlun Mountains to the south, the Pamir Mountains to the west, the Tian Shan range to the north, and the Gobi Desert to the east. Etymology While most researchers agree on being the Persian language, Persian word for "place", etymology of ''Takla'' is less clear. The word may be a Uyghur language, Uyghur borrowing of the Persian , "to leave alone/out/behind, relinquish, abandon" + ''makan''. Another plausible explanation suggests it is derived from Chagatai language, Turki ''taqlar makan'', describing "the place of ruins". Chinese scholars Wang Guowei and Huang Wenbi linked the name to the Tocharians, a historical people of the Tarim Basin, making th ...
