The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa.
Hazels are plants of the genus Corylus of deciduous trees and large shrubs native to the temperate Northern Hemisphere. The genus is usually placed in the birch family Betulaceae, though some botanists split the hazels into a separate family Corylaceae. The fruit of the hazel is the hazelnut.
Celtis is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, widespread in warm temperate regions of the Northern Hemisphere. The genus is part of the extended Cannabis family (Cannabaceae).
The chukar partridge, or simply chukar, is a Palearctic upland gamebird in the pheasant family Phasianidae. It has been considered to form a superspecies complex along with the rock partridge, Philby's partridge and Przevalski's partridge and treated in the past as conspecific particularly with the first. This partridge has well-marked black and white bars on the flanks and a black band running from the forehead across the eye down the head to form a necklace that encloses a white throat. Native to Asia, the species has been introduced into many other places and feral populations have established themselves in parts of North America and New Zealand. This bird can be found in parts of Middle East and temperate Asia.
Lamium (dead-nettles) is a genus of about 30 species of flowering plants in the family Lamiaceae, of which it is the type genus. They are all herbaceous plants native to Europe, Asia, and northern Africa, but several have become very successful weeds of crop fields and are now widely naturalised across much of the temperate world.
Limonium is a genus of about 600 flowering plant species. Members are also known as sea-lavender, statice, caspia or marsh-rosemary. Despite their common names, species are not related to the lavenders or to rosemary. They are instead in Plumbaginaceae, the plumbago or leadwort family. The generic name is from the Latin līmōnion, used by Pliny for a wild plant and is ultimately derived from the Ancient Greek leimon.
The Papaveraceae, informally known as the poppy family, are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales. The family is cosmopolitan, occurring in temperate and subtropical climates like Eastern Asia as well as California in North America. It is almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae. Papaver is the classical name for poppy in Latin.
The Crypteroniaceae are a family of flowering trees and shrubs. The family includes 13 species in three genera, native to Indomalaya.
Ephedra is a genus of gymnosperm shrubs. The various species of Ephedra are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three living members of the division Gnetophyta alongside Gnetum and Welwitschia.
Alhagi is a genus of Old World plants in the family Fabaceae. They are commonly called camelthorns or manna trees. There are four accepted species, which range from northern Africa and Greece through western and central Asia to India and northern China.
Olacaceae is a family of flowering plants in the order Santalales. They are woody plants, native throughout the tropical regions of the world. As of July 2021, the circumscription of the family varies; some sources maintain a broad family, others split it into seven segregate families.
Cyrtostachys is a genus of flowering plant in the family Arecaceae. Its species are found in southeast Asia, New Guinea, and in some of the South-Central and Southwest Pacific island habitats of the Oceanian realm.
Parapodia is a monotypic moth genus in the family Gelechiidae described by Joseph de Joannis in 1859. It contains the species Parapodia sinaica, described by Georg Ritter von Frauenfeld in 1859, which is found in Arabia, the Sinai desert, Palestine and southern France.
Selinum carvifolia is a flowering plant of the genus Selinum in the family Apiaceae. The specific name carvifolia signifies 'having leaves resembling those of Caraway'. It is a plant of fens and damp meadows, growing in most of Europe, with the exception of much of the Mediterranean region, eastwards to Central Asia. Its common name in English is Cambridge milk parsley, because it is confined, in the UK, to the county of Cambridgeshire and closely resembles milk parsley, an umbellifer of another genus, but found in similar habitats. The two plants are not only similar in appearance, but also grow in similar moist habitats, although they may be told apart in the following manner: P. palustre has hollow, often purplish stems, pinnatifid leaf lobes and deflexed bracteoles; while S. carvifolia has solid, greenish stems, entire or sometimes lobed leaf-lobes and erecto-patent bracteoles. Also, when the two plants are in fruit, another difference becomes apparent: the three dorsal ridges on the fruit of S. carvifolia are winged, while those on the fruit of P. palustre are not. Yet a further difference lies in the respective leaflets of the plants : those of Peucedanum palustre are blunt and pale at the tip, while those of Selinum carvifolia are sharply pointed and of a darker green. S. carvifolia used also to occur in the English counties of Nottinghamshire and Lincolnshire but is now extinct in both. Growing in only three small Cambridgeshire fens, it is one of England's rarest umbellifers. It is naturalized in the United States, where it is known by the common name little-leaf angelica.
Acentrella is a genus of small minnow mayflies in the family Baetidae. Species of Acentrella are recorded from Europe, North America and Asia, with a few from Africa.
Crataegus × sinaica is a hawthorn that originated as a hybrid between two other hawthorn species, C. azarolus in series Orientales and C. monogyna in series Crataegus. It has been placed in the nothosection Orientaegus. It grows in the central and eastern parts of the Mediterranean region on rocky mountain slopes. In Egypt it grows in the mountains near Saint Catherine in South Sinai, where it is known as za'rur or za'rur al-awdiyah.
Vicia sinaica is a species of flowering plant in the family Fabaceae, endemic to the Sinai Peninsula. A very rare therophyte found in plains, depressions, and wadis, it is believed to be extinct.
