Devil’s-bit Scabious
''Succisa pratensis'', also known as devil's-bit or devil's-bit scabious, is a flowering plant in the honeysuckle family Caprifoliaceae. It differs from other similar species in that it has four-lobed flowers, whereas ''Scabiosa columbaria'' (small scabious) and ''Knautia arvensis'' (field scabious) have five lobes and hence it has been placed in a separate genus in the same family. It also grows on damper ground. Name Species of scabious were used to treat scabies, and other afflictions of the skin including sores caused by the bubonic plague. The word scabies comes from the Latin word for "scratch" (scabere). In folk tales, the short black root was bitten off by the devil, for various reasons: anger at the plant's ability to cure these ailments, anger against the Virgin Mary, or as part of some 'devilish plot'. The Latin specific epithet ''pratensis'' literally means "of the meadow". Description ''Succisa pratensis'' is a herbaceous perennial up to 1m tall, growing from a ba ...

Conrad Moench
Conrad Moench (sometimes written Konrad Mönch; 15 August 1744 – 6 January 1805) was a German botanist, professor of botany at Marburg University from 1786 until his death. He wrote ''Methodus Plantas horti botanici et agri Marburgensis''; in 1794, an arranged account of plants in the fields and gardens of Marburg. Largely in this work, and in a supplement published in 1802, Moench published over 1,500 original scientific names of plants, including about 150 genera. The genera include '' Bergenia'', '' Echinacea'', '' Galactites'', '' Kniphofia'', '' Olearia'', and ''Sorghum''. The botanical genus '' Moenchia'' (family Caryophyllaceae Caryophyllaceae, commonly called the pink family or carnation family, is a family (biology), family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranth ...) is named in his honor. The standard botanical author abbreviation Moench is applied to plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudanthium
A pseudanthium (; : pseudanthia) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (biology), family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla (flower), corolla is fused into a tube. Flowers on th ...

Meloidogyne Hapla
Northern root-knot nematode (''Meloidogyne hapla'') is a species of vegetable pathogens which produces tiny galls on around 550 crop and weed species. They invade root tissue after birth. Females are able to lay up to 1,000 eggs at a time in a large egg mass. By surviving harsh winters, they can survive in cold climates (hence, the name, Northern). Hosts and symptoms ''Meloidogyne hapla'' (Northern root-knot nematode) has a wide host range. It is polyphagous and affects over 550 crops and weeds. It feeds on many agricultural and horticultural plants (vegetables, fruits, ornamentals), but few grasses or cereals. A list of known hosts can be found at the bottom of this page. Symptoms can be seen in the roots, leaves, and the overall growth of the infected plant. In roots, there may be stunting, wilting, and the formation of abnormal growths called galls. Galls are usually small and spherical and are situated near many small roots. They are formed when the nematode enters the ro ...

Nematode
The nematodes ( or ; ; ), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic. Parasitic worms (helminths) are the cause of soil-transmitted helminthiases. They are classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa. Unlike the flatworms, nematodes have a tubular digestive system, with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species are uncertain. A 2013 survey of animal biodiversity suggested there are over 25,000. Estimates of the total number of extant species are su ...
