Tonkinbolus is a genus of millipedes in the family Pachybolidae. It contains species found in Myanmar and Vietnam. [1] :100 The species Tonkinbolus caudulanus was described by Karsch in 1881, and the genus was named by Verhoeff in 1938. [1] :90
Aster is a genus of perennial flowering plants in the family Asteraceae. Its circumscription has been narrowed, and it now encompasses around 180 species, all but one of which are restricted to Eurasia; many species formerly in Aster are now in other genera of the tribe Astereae. Aster amellus is the type species of the genus and the family Asteraceae.
The pecan is a species of hickory native to northern Mexico and the southern United States in the region of the Mississippi River. The tree is cultivated for its seed in the southern United States, primarily in Georgia, New Mexico, and Texas, and in Mexico, which produces nearly half of the world total. The seed is an edible nut used as a snack and in various recipes, such as praline candy and pecan pie. The pecan, in various aspects, is included in state symbols of Alabama, Arkansas, California, Oklahoma, and Texas.

Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection. The reduction of fruit quality and yield may result in crop losses of up to 70%, posing a significant threat to the profitability of apple producers. To reduce scab-related yield losses, growers often combine preventive practices, including sanitation and resistance breeding, with reactive measures, such as targeted fungicide or biocontrol treatments, to prevent the incidence and spread of apple scab in their crops.
The Phytomyxea are a class of parasites of plants. They are divided into the orders Plasmodiophorida and Phagomyxida. A more common name for them is the plasmodiophorids, but this does not always include Phagomyxa.
Boletus is a genus of mushroom-producing fungi, comprising over 100 species. The genus Boletus was originally broadly defined and described by Carl Linnaeus in 1753, essentially containing all fungi with hymenial pores instead of gills. Since then, other genera have been defined gradually, such as Tylopilus by Petter Adolf Karsten in 1881, and old names such as Leccinum have been resurrected or redefined. Some mushrooms listed in older books as members of the genus have now been placed in separate genera. These include such as Boletus scaber, now Leccinum scabrum, Tylopilus felleus, Chalciporus piperatus and Suillus luteus. Most boletes have been found to be ectomycorrhizal fungi, which mean that they form a mutualistic relationship with the roots system of certain kinds of plants. More recently, Boletus has been found to be massively polyphyletic, with only a small percentage of the over 300 species that have been assigned to Boletus actually belonging there and necessitating the description and resurrection of many more genera.
Eccremocarpus is a genus of five species of flowering plants in the family Bignoniaceae, native to western South America in Chile, western Argentina, and Peru. The species are evergreen semi-woody vines growing to 1–7 m tall.
Leccinum is a genus of fungi in the family Boletaceae. It was the name given first to a series of fungi within the genus Boletus, then erected as a new genus last century. Their main distinguishing feature is the small, rigid projections (scabers) that give a rough texture to their stalks. The genus name was coined from the Italian Leccino, for a type of rough-stemmed bolete. The genus has a widespread distribution, especially in north temperate regions, and contains about 75 species.
Leccinum aurantiacum is a species of fungus in the genus Leccinum found in forests of Europe, North America, and Asia and has a large, characteristically red-capped fruiting body. In North America, it is sometimes referred to by the common name red-capped scaber stalk. Some uncertainties exist regarding the taxonomic classification of this species in Europe and North America. It is considered edible.
Malus floribunda, common name Japanese flowering crabapple, Japanese crab, purple chokeberry, or showy crabapple, originates from Japan and East Asia. It may be a wild species, or a hybrid of M. sieboldii × M. baccata.
Porcellio is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, Porcellio scaber.
Blepharipappus is a North American plant genus in the daisy family containing the single known species Blepharipappus scaber, known by the common name rough eyelash, or rough eyelashweed.
Psoroptes is a genus of mites, including the agents that cause psoroptic mange.
Eriochilus, commonly known as bunny orchids, is a genus of flowering plants in the orchid family, Orchidaceae that is endemic to Australia. Orchids in this genus are distinguished from those in the similar Caladenia by having a glabrous leaf and a densely woolly labellum. Species occur in south-west Western Australia, South Australia, Queensland, New South Wales, the Australian Capital Territory, Victoria, and Tasmania. Their common name alludes to their prominent ear-like lateral sepals.
Otiorhynchus is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil and the strawberry root weevil, are important pests, both as larvae and as adults. Larvae feed on plant roots. Adults are flightless with fused elytra and feed at night on plant foliage. In many species of the genus at least some races are polyploid and parthenogenetic, while the rest of the races and species are diploid and bisexual. Otiorhynchus weevils, particularly O. scaber, have been a popular subject for studies of the evolution of parthenogenesis. The genus is native to the Palearctic region. However, sixteen species were inadvertently introduced to North America and have become widespread there.
Elephantopus is a genus of perennial plants in the daisy family (Asteraceae).
Leccinum manzanitae is an edible species of bolete fungus in the family Boletaceae. Described as new to science in 1971, it is commonly known as the manzanita bolete for its usual mycorrhizal association with manzanita trees. Its fruit bodies (mushrooms) have sticky reddish to brown caps up to 20 cm (7.9 in), and its stipes are up to 16 cm (6.3 in) long and 3.5 cm (1.4 in) thick. They have a whitish background color punctuated with small black scales known as scabers. Found only in the Pacific Northwest region of the United States and Canada, it is the most common Leccinum species in California. The mushroom is edible, although opinions vary as to its quality. L. manzanitae can be usually distinguished from other similar bolete mushrooms by its large size, reddish cap, dark scabers on a whitish stipe, and association with manzanita and madrone.
Uranoscopus is a genus of stargazer fish from the family Uranoscopidae. The name Uranoscopus is from the Greek, ouranos, "sky" and skopein, "to watch".
The PRI disease resistant apple breeding program is a joint project of the Purdue University, Rutgers University, and the University of Illinois, to breed apple cultivars to be resistant to apple scab. PRI stands for 'P'urdue, 'R'utgers and 'I'llinois.
Protea scabra, also known as the sandpaper-leaf sugarbush, is a flowering groundcover that belongs to the genus Protea. The plant is endemic to South Africa and is found from the Hottentots Holland Mountains across the Riviersonderend Mountains, the Kleinrivier Mountains and around the town of Caledon to the Swartberg mountains.
