Philipp Christoph Zeller
Philipp Christoph Zeller (8 April 1808 – 27 March 1883) was a German entomologist. Zeller was born at Steinheim an der Murr, Württemberg, two miles from Marbach, the birthplace of Schiller. The family moved to Frankfurt (Oder) where Philipp went to the gymnasium where natural history was not taught. Instead, helped by Alois Metzner, he taught himself entomology mainly by copying books. Copying and hence memorising, developed in response to early financial privation became a lifetime habit. Zeller went next to the University of Berlin where he became a candidat, which is the first degree, obtained after two or three years' study around 1833. The subject was philology. He became an Oberlehrer or senior primary school teacher in Glogau in 1835. Then he became an instructor at the secondary school in Frankfurt (Oder) and in 1860 he was appointed as the senior instructor of the highest technical high school in Meseritz. He resigned this post after leaving in 1869 for Stettin, ...

Deschampsia Caespitosa
''Deschampsia cespitosa'', commonly known as tufted hairgrass or tussock grass, is a perennial tufted plant in the grass family Poaceae. Distribution of this species is widespread including the eastern and western coasts of North America, parts of South America, Eurasia and Australia. The species is cultivated as an ornamental garden plant, and numerous cultivars are available. The cultivars 'Goldschleier' and 'Goldtau' have gained the Royal Horticultural Society's Award of Garden Merit. It is a larval host to the Juba skipper and the umber skipper. Description A distinguishing feature is the upper surface of the leaf blade which feels rough and can cut in one direction, but is smooth in the opposite direction. The dark green upper sides of the leaves are deeply grooved. It can grow to tall, and has a long, narrow, pointed ligule. It flowers from June until August. It can be found on all types of grassland, although it prefers poorly drained soil. It forms a major componen ...

Elachista
''Elachista'' is a genus of gelechioid moths described by Georg Friedrich Treitschke in 1833. It is the type genus of the grass-miner moth family (Elachistidae). This family is sometimes (in particular in older sources) circumscribed very loosely, including for example the Agonoxenidae and Ethmiidae which seem to be quite distinct among the Gelechioidea, as well as other lineages which are widely held to be closer to '' Oecophora'' than to ''Elachista'' and are thus placed in the concealer moth family Oecophoridae here. These grass-miners are very small moths with the "feathery" hindwings characteristic of their family. They are essentially found worldwide, except in very cold places and on some oceanic islands; as usual for Gelechioidea, they are most common in the Palearctic however. They usually have at least one, sometimes as many as three light bands running from leading to trailing edge of their forewing uppersides. Some species, however, have upper forewings that are mostl ...

Poa Pratensis
''Poa pratensis'', commonly known as Kentucky bluegrass (or blue grass), smooth meadow-grass, or common meadow-grass, is a perennial species of grass native to practically all of Europe, North Asia and the mountains of Algeria and Morocco. Although the species is spread over all of the cool, humid parts of the United States, it is not native to North America. The Spanish Empire brought the seeds of Kentucky bluegrass to the New World in mixtures with other grasses. In its native range, ''Poa pratensis'' forms a valuable pasture plant, characteristic of well-drained, fertile soil. It is also used for making lawns in parks and gardens and has established itself as a common invasive weed across cool moist climates like the Pacific Northwest and the Northeastern United States. When found on native grasslands in Canada, for example, it is considered an unwelcome exotic plant, and is indicative of a disturbed and degraded landscape. Taxonomy ''Poa pratensis'' was one of the many spec ...

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and ''Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, wit ...

Helictotrichon Sedenense
''Helictotrichon'', or alpine oatgrass, is a genus of perennial flowering plants in the grass family. The genus name comes from the Greek ''heliktos'' meaning twisted, and ''trichos'' meaning hair, referring to the shape of the awn. Most of the species are native to Africa and Eurasia with a few species in North America.

Festuca Trachyphylla
''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.

Festuca Rubra
''Festuca rubra'' is a species of grass known by the common name red fescue or creeping red fescue. It is widespread across much of the Northern Hemisphere and can tolerate many habitats and climates. It is best adapted to well-drained soils in cool, temperate climates; it prefers shadier areas and is often planted for its shade tolerance. Wild animals browse it, but it has not been important for domestic forage due to low productivity and palatability. It is also an ornamental plant for gardens. Description ''Festuca rubra'' is perennial and has sub-species that have rhizomes and/or form bunchgrass tufts. It mainly exists in neutral and acidic soils. It can grow between 2 and 20 cm tall. Like all fescues, the leaves are narrow and needle like, making it less palatable to livestock. The swards that it forms are not as tufted as sheep's fescue (''Festuca ovina'') or wavy hair grass (''Deschampsia flexuosa''). The tufted nature is what gives the grass its springy characteri ...

Festuca Ovina
''Festuca ovina'', sheep's fescue or sheep fescue, is a species of grass. It is sometimes confused with hard fescue (''Festuca trachyphylla''). General description It is a perennial plant sometimes found in acidic ground, and in mountain pasture, throughout Europe (with the exception of some Mediterranean areas) and eastwards across much of Asia; it has also been introduced to North America. It is one of the defining species of the British NVC community CG2, i.e. ''Festuca ovina'' – '' Avenula pratensis'' grassland, one of the calcicolous grassland communities. However, the species has a wide ecological tolerance in the UK, occurring on both basic and acid soils, as well as old mining sites and spoil heaps that are contaminated with heavy metals. Sheep's fescue is a densely tufted perennial grass. Its greyish-green leaves are short and bristle-like. The panicles are both slightly feathery and a bit one-sided. It flowers from May until June, and is wind-pollinated. It has no ...
