Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
Crataegus, commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, Mayflower or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa and North America. The name "hawthorn" was originally applied to the species native to northern Europe, especially the common hawthorn C. monogyna, and the unmodified name is often so used in Britain and Ireland. The name is now also applied to the entire genus and to the related Asian genus Rhaphiolepis.
Crataegus monogyna, known as common hawthorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family Rosaceae. It is native to Europe, northwestern Africa, and West Asia, but has been introduced in many other parts of the world.
Citrus × meyeri, the Meyer lemon, is a hybrid citrus fruit native to China. It is not a lemon, but is instead a cross between a citron and a mandarin/pomelo hybrid.
Crataegus laevigata, known as the Midland hawthorn, English hawthorn, woodland hawthorn, or mayflower, is a species of hawthorn native to western and central Europe, from Great Britain and Spain east to the Czech Republic and Hungary. It is also present in North Africa. The species name is sometimes spelt C. levigata, but the original orthography is C. lævigata.
The brown sicklebill is a species of bird-of-paradise that is found in the mountain forests of New Guinea.
Meyer's parrot, also known as the brown parrot, is a species of parrot native to Africa. A Meyer's parrot has grey feathers, turquoise belly, blue rump, and bright yellow markings on the carpal joint of the wings. Most subspecies have some yellow on the top of the head as well. Forshaw (1989) recognizes six subspecies of P. meyeri which vary in home range, size and in markings, including the extent of yellow markings to the head and wings, and the intensity of turquoise markings on the belly and rump.
The trefoil-toothed giant rat is a species of rodent in the family Muridae. It is found only in Sulawesi, Indonesia, where it is located throughout the island.
The scrawled butterflyfish, also known as Meyer's butterflyfish or the maypole butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian and Pacific Oceans.
Crataegus orientalis, known as oriental hawthorn, is a species of hawthorn native to the Mediterranean region, Turkey, Caucasia, Crimea, and western Iran, with fruits that are orange or various shades of red.
Crataegus coccinea, the scarlet hawthorn, is a species of hawthorn around which there is considerable confusion because the name has been misapplied for a long time. It has been shown to be the same as C. pedicellata, and under the rules of botanical nomenclature, the older name should be used.
Phyllonorycter oxyacanthae is a moth of the family Gracillariidae. It is found in all of Europe except the Balkan Peninsula.
Stigmella oxyacanthella is a moth of the family Nepticulidae, found in Europe and North America. The larvae are leaf miners feeding inside the leaves of trees and shrubs, such as hawthorn, apple and pear.
Stigmella crataegella is a moth of the family Nepticulidae found in Europe. It was described by the Austrian entomologist Josef Wilhelm Klimesch in 1936. The larvae mine the leaves of hawthorns.
Graphium meyeri is a species of butterfly of the family Papilionidae, that is found in Sulawesi. Very little is known about this species.
The Stellenbosch University Botanical Garden located in the historical center of Stellenbosch is the oldest university botanical garden in South Africa. The Garden is relatively small and houses an enormous diversity of plants, both indigenous to South Africa and introduced species. It is open to the public.
Crataegus suksdorfii,, formerly Crataegus douglasii var. suksdorfii, is a species of hawthorn found in the Pacific Northwest. It is diploid versus tetraploid for Crataegus douglasii. The most significant morphological difference from C. douglasii is that it has 20 stamens rather than 10. The two species are found in different geographic ranges, have different flowering times, and different time lengths for fruit development.
Orcinus meyeri is a fossil species of Orcinus found in the Early Miocene deposits of southern Germany, known from two jaw fragments and 18 isolated teeth. It was originally described as Delphinus acutidens in 1859, but reclassified in 1873. Its validity is disputed, and it may be a synonymous with the ancient sperm whale Physeterula dubusi. It was found in the Alpine town of Stockach in the Molasse basin, which was a coastal area with strong tidal currents.
Crataegus ucrainica is a putative species of hawthorn found in Ukraine. A 2014 molecular and morphological study reduced it to a synonym of Crataegus meyeri.
Crataegus × yosgatica or Crataegus yosgatica is a putative hybrid species of hawthorn. It was thought to be a cross between Crataegus monogyna and C. tanacetifolia. A 2014 molecular and morphological study reduced it to a synonym of Crataegus meyeri.
