Which tree belongs to the genus Betula?
"sores. It has a strong tendency to epicormic growth resulting in a habit of many small limbs sprouting from the trunk causing the wood to be full of small knots. Betula occidentalis Betula occidentalis, the water birch or red birch, is a species of birch native to western North America, in Canada from Yukon east to western Ontario and southwards, and in the United States from eastern Washington east to western North Dakota, and south to eastern California, northern Arizona and northern New Mexico, and southwestern Alaska. It typically occurs along streams in mountainous regions. It is a deciduous shrub"
"Betulaceae Betulaceae, the birch family, includes six genera of deciduous nut-bearing trees and shrubs, including the birches, alders, hazels, hornbeams, hazel-hornbeam, and hop-hornbeams numbering a total of 167 species. They are mostly natives of the temperate Northern Hemisphere, with a few species reaching the Southern Hemisphere in the Andes in South America. Their typical flowers are catkins and often appear before leaves. In the past, the family was often divided into two families, Betulaceae (""Alnus"", ""Betula"") and Corylaceae (the rest). Recent treatments, including the Angiosperm Phylogeny Group, have described these two groups as subfamilies within an expanded Betulaceae: Betuloideae and"
"side. In cross section they appear lobed. Common shrub associates within the chaparral community include toyon. The leaves are distinctive in that they have smooth edges from the base to about half way up, then are wavy or toothed to the rounded tip. ""Betula"" is the birch genus, and the species name refers to the birch-like leaves. The white flowers are small, clustered, and mildly scented, similar to acacia. The fruit is a tubular achene with the long, plumelike flower style still attached. The genus name comes from the Greek ""kerkos"" (""tail""), referring to the tail-like appearance of the fruit;"
"Agathosma betulina Agathosma betulina (previously ""Barosma betulina"") is a flowering plant in the family Rutaceae, native to the lower elevation mountains of western South Africa, where it occurs near streams in fynbos habitats. It is an evergreen shrub growing to tall. The leaves are opposite, rounded, about long and broad. The flowers are white or pale pink, with five petals; the fruit is a five-parted capsule which splits open to release the seeds. It is known by the common name round leaf buchu. The very similar plant ""Agathosma crenulata"" (previously ""Barosma crenulata"") is known as the oval leaf buchu, and"

A field study in Scotland concluded that the species is more likely to be present in older than in younger birch woodlands. Fruit bodies grow on the ground, scattered or grouped together. They are a component of the diet of the red squirrel, and serve as breeding sites for some fungus-feeding flies in the Drosophilidae and Mycetophilidae families. ""Lactarius torminosus"" mushrooms may be parasitized by the mold ""Hypomyces lithuanicus"", which produces a cream-ochre to cinnamon-colored granular or velvety growth"
"strictly, two filaments divided into two branches, each bearing a half-anther. Anther cells open longitudinally. The pistillate aments are erect or pendulous, solitary; terminal on the two-leaved lateral spur-like branchlets of the year. The pistillate scales are oblong-ovate, three-lobed, pale yellow-green often tinged with red, becoming brown at maturity. These scales bear two or three fertile flowers, each flower consisting of a naked ovary. The ovary is compressed, two-celled, and crowned with two slender styles; the ovule is solitary. Each scale bears a single small, winged nut that is oval, with two persistent stigmas at the apex. ""Betula"" species are"

The common hazel (""Corylus avellana"") and the filbert (""Corylus maxima"") are important orchard plants, grown for their edible nuts.

It is commonly known as the birch brittlegill. The specific epithet ""betularum"" ""of the birches"", refers to its association with birch (""Betula"" species).

"Urtica ferox Urtica ferox, commonly known as tree nettle, or ongaonga in Māori, is a nettle that is endemic to New Zealand. It is sometimes known as ""Taraonga"", ""Taraongaonga"" or ""Okaoka"". Unlike other herbaceous species in the genus ""Urtica"", ongaonga is a large woody shrub. It has woody stems and unusually large stinging spines that can result in a painful sting that lasts several days. The shrub can grow to a height of with the base of the stem reaching in thickness. Ongaonga is the main food plant for larvae of the New Zealand red admiral butterfly or kahukura, ""Vanessa"
"Alder Alder is the common name of a genus of flowering plants (Alnus) belonging to the birch family Betulaceae. The genus comprises about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes. The common name ""alder"" evolved from Old English ""alor"", which in turn is derived from Proto-Germanic root ""aliso"". The generic name ""Alnus"" is the equivalent Latin name. Both the Latin and the Germanic words derive from the Proto-Indo-European root ""el-"", meaning ""red"""

"Cortusa Cortusa is a genus that consists of 19 species of delicate, hardy, alpine perennials, relative to ""Primula"" both in general appearance and habit of growth. The genus is named by the herbalist Matthiolus after his friend Cortusus, professor of botany at Padua, who discovered the plant called today ""Cortusa matthioli"". The plants are flowering herbaceous perennials native to the mountains of southern and eastern Europe, including the Alps and the Carpathians, and some species native to China. Most of the species are small spring bloomers for shade and rock garden. These low-growing and rather handsome little plants have clumps"
"of the Betulaceae into six genera is uncontroversial, the placement of these genera into higher taxonomic ranks and the level of these ranks are debated. Extensive studies on the basis of ribulose- 1,5-biphosphate carboxylase (""rbc""L) sequences, internal transcribed spacer (ITS) sequences, morphology, and various combined data sets support the dichotomy of the Betulaceae into two major clades. A few authors have divided the genera into two families, the Betulaceae (""Alnus"", ""Betula"") and Corylaceae (""Carpinus"", ""Ostrya"", ""Corylus"", ""Ostryopsis""). Many modern authors recognize two separate clades within the family, either as tribes Betuleae and Coryleae or subfamilies Betuloideae and Coryloideae. There has"

It takes both its common and its scientific name from its bell-shaped flowers—""campanula"" is Latin for ""little bell"". The genus includes over 500 species and several subspecies, distributed across the temperate and subtropical regions of the Northern Hemisphere, with the highest diversity in the Mediterranean region east to the Caucasus.

"Cotula Cotula is a genus of flowering plant in the sunflower family. It includes plants known generally as water buttons or buttonweeds. The species within this genus can vary extensively in their habit, leaf division, involucre, receptacle and achenes. This makes it difficult to define them by comparing their morphology. The genus can only be defined by looking at the corollas of their flowers. Most are disciform (lacking ray florets). These corollas may be tubular, reduced or even absent. Another characteristic is their solitary heads growing on a peduncle. ""Cotula"" is the largest genus found in the Southern Hemisphere of"
