Festuca Gautieri
''Festuca gautieri'', commonly known as spiky fescue or bearskin fescue, is a species of flowering plant in the grass family, Poaceae, native to the Pyrenees. It is a commonly cultivated evergreen or semi-evergreen herbaceous perennial, and, as a native to European alpine areas, it is a small, low-growing ''Festuca'' suitable for rock gardens. Description The bearskin fescue is a persistent, overwintering green grass with about 20 to 50 centimeters high and bare stalks, which have a diameter of 0.9 to 1.7 millimeters. It has dense horst-like growth with very thin, bristly to rush-shaped, folded leaves that are closed tubularly to one-third to three-quarters of their length. The leaf blades carry five to seven vascular bundles. The ligules are membranous, slightly fringed and about 0.5 to 1 millimeter long. The yellow-green inflorescence is a panicle that reaches a length of about 4.5 to 7 centimetres. The panicle branches are hairy and each carry an elongated, flattened spikel ...

Eduard Hackel
Eduard Hackel (17 March 1850, Haida, Bohemia – 2 February 1926, Attersee, Upper Austria) was an Austrian botanist. His father was a veterinarian in Haida (now Nový Bor) in Bohemia. He was married and had one son. Hackel studied at the Polytechnical Institute in Vienna, and became substitute teacher at a high school in St. Pölten in 1869. He became full professor of natural history there upon obtaining his teaching certificate in 1871 and remained in this position until his retirement in 1900. Agrostology He published his first agrostology papers on grasses in 1871 and soon became known as a world expert agrostologist on the grass family (Poaceae). While he himself undertook only a single collecting trip – to Spain and Portugal, he was charged with working up collections of grasses mainly from Japan, Taiwan, New Guinea, Brazil and Argentina. Apart from agrostologisty systematics, Hackel also contributed to the morphology and histology of members of the grass family. T ...

Vascular Bundle
A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in the stem, which exists in two forms: xylem and phloem. Both these tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. In addition, there is also a tissue between xylem and phloem which is the cambium. The xylem typically lies towards the axis ( adaxial) with phloem positioned away from the axis ( abaxial). In a stem or root this means that the xylem is closer to the centre of the stem or root while the phloem is closer to the exterior. In a leaf, the adaxial surface of the leaf will usually be the upper side, with the abaxial surface the lower side. The sugars synthesized by the plant with sun light are transported by the phloem, which is closer to the lower surface. Aphids and leaf hoppers feed off of these sugars by tapping into the phloem. This is why aphids and leaf hoppers are typically found on the unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus '' Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Container Garden
Container gardening or pot gardening/farming is the practice of growing plants, including edible plants, exclusively in containers instead of planting them in the ground. A container in gardening is a small, enclosed and usually portable object used for displaying live flowers or plants. It may take the form of a pot, box, tub, basket, tin, barrel or hanging basket. Methods Pots, traditionally made of terracotta but now more commonly plastic, and window boxes are the most commonly seen. Small pots are called flowerpots. In some cases, this method of growing is used for ornamental purposes. This method is also useful in areas where the soil or climate is unsuitable for the plant or crop in question. Using a container is also generally necessary for houseplants. Limited growing space, or growing space that is paved over, can also make this option appealing to the gardener. Additionally, this method is popular for urban horticulture and urban gardening on balconies of apa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Festuca Eskia
''Festuca eskia'' is a species of grass which is native to southwestern Europe, in France and Spain. Description The plant is perennial and has caespitose with long culms and wide. The ligule is long and is going around the eciliate membrane. Leaf sheaths are smooth and have a hairy surface while the leaf-blades are straight but curved and are broad. The panicle is contracted, linear, inflorescenced and long with branch A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk (botany), trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term '' ...es being as hairy as leaf-sheaths.

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in floweri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Organisms By Chromosome Count
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cell (biology), cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype, and can be found by looking at the chromosomes through a microscope. Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics. The preparation and study of karyotypes is part of cytogenetics. File:Human karyotype with bands and sub-bands.png, Karyotype of a human being.

Palea (botany)
A spikelet, in botany, describes the typical arrangement of the flowers of grasses, sedges and some other Monocots. Each spikelet has one or more florets. The spikelets are further grouped into panicles or spikes. The part of the spikelet that bears the florets is called the rachilla. In grasses In Poaceae, the grass family, a spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. Lemma Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
