Tiarella
''Tiarella'', the foamflowers, is a genus of flowering plants in the family (biology), family Saxifragaceae. The generic name ''Tiarella'' means "little turban", which suggests the shape of the seed capsules. Worldwide there are seven species, one each in eastern Asia and western North America, plus five species in eastern North America. , the taxonomy of ''Tiarella'' in eastern North America is in flux. Description Plants of genus ''Tiarella'' are Perennial plant, perennial, herbaceous plants with short, slender rhizomes. Three Morphology (biology), morphological features are used to distinguish ''Tiarella'' species: 1) presence or absence of stolons; 2) size and shape of basal leaves; and 3) presence or absence of stem leaves (also called cauline leaves). Two species of ''Tiarella'' have stolons (''T. austrina'', ''T. stolonifera'') while two other species have stem leaves (''T. nautila'', ''T. austrina''). Plants from the southern Blue Rid ...

Tiarella Cordifolia
''Tiarella cordifolia'', the heart-leaved foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name ''cordifolia'' means "with heart-shaped leaves", a characteristic shared by all taxa of ''Tiarella'' in eastern North America. It is also referred to as Allegheny foamflower, false miterwort, and coolwort. Historically, the name ''Tiarella cordifolia'' has referred to the one and only species of ''Tiarella'' in eastern North America, but in 2021, the species was split into multiple taxa, which caused the name to have a different meaning. For clarity, the qualified name ''Tiarella cordifolia'' sensu stricto (abbreviated s.s.) refers to the new taxon while ''Tiarella cordifolia'' sensu lato refers to the old taxon. ''Tiarella cordifolia'' sensu lato is wide-ranging across eastern North America while ''Tiarella cordifolia'' sensu stricto is narrowly confined to the East Coast of the United States. Cultivars of ''Tiarella'' are valued in horticulture fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiarella Trifoliata
''Tiarella trifoliata'', the three-leaf foamflower, is a species of flowering plant in the family Saxifragaceae. The specific name ''trifoliata'' means "having three leaflets", a characteristic of two of the three recognized varieties. Also known as the laceflower or sugar-scoop, the species is found in shaded, moist woods in western North America. Description ''Tiarella trifoliata'' is a perennial dicotyledonous herb that flowers in the late spring. The flowers are bell-shaped, white and solitary forming an elongated, leafless panicle. The calyx lobes are 1.5–2.5 mm and petals are 3–4 mm. Basal leaves are 15–80 mm long and up to 120 mm wide, trifoliate or palmately 3- to 5-lobed. Cauline leaves are infrequent and much smaller. The typical variety of ''Tiarella trifoliata'' (var. ''trifoliata'') has petiolate leaves with three leaflets per leaf (i.e., trifoliate). The cut-leaved foamflower (var. ''laciniata'') also has trifoliate leaves with p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiarella Stolonifera
''Tiarella stolonifera'' is a species of flowering plant in the family (biology), family Saxifragaceae. The specific name ''stolonifera'' means "spreading by stolons", an important characteristic of this species (not to be confused with ''Tiarella austrina'', which also spreads by stolons). Known as the creeping foamflower, it has the widest range of any species of ''Tiarella'' in eastern North America. Description ''Tiarella stolonifera'' is a Perennial plant, perennial, herbaceous plant with a short, slender rhizome. It has a leafless flowering stem and relatively small basal leaves without an extended terminal lobe. Most importantly, the species has the ability to produce stolons. The heart-shaped basal leaves of ''Tiarella stolonifera'' resemble those of species in other genera. For example, ''T. stolonifera'' is sometimes confused with ''Mitella diphylla'', a closely related species that occurs over a similar range and habitat. If a plant lacks sufficient evidence of ...

Tiarella Wherryi
''Tiarella wherryi'' is a species of flowering plant in the family Saxifragaceae. The specific epithet ''wherryi'' recognizes Edgar Wherry, the botanist who collected some of the first specimens in the early 1930s. Commonly called Wherry's foamflower, it is the southernmost of all species of ''Tiarella'' in the southeastern United States, where its range approaches the Gulf Coast in southern Alabama. Description ''Tiarella wherryi'' is a perennial, herbaceous plant with a short, slender rhizome. It has a leafless flowering stem and relatively large basal leaves, each with an extended terminal lobe. Most importantly, the species lacks the ability to produce stolons. Identification To positively identify ''Tiarella wherryi'', all of the following key features must be verified (in any order): * Stolon always absent * Basal leaves usually longer than wide * Basal leaf lobes usually acute-acuminate with the terminal lobe prominently extended * Flowering stem without leaves or foliac ...

Tiarella Austrina
''Tiarella austrina'' is a species of flowering plant in the family Saxifragaceae. The specific name ''austrina'' means "from the south". Being endemic to the southeastern United States, it is sometimes referred to as the southern foamflower. It is one of two species of ''Tiarella'' that spread by stolons (the other being '' Tiarella stolonifera''). Description ''Tiarella austrina'' is a perennial, herbaceous plant with a short, slender rhizome. It has a leafy flowering stem and relatively large basal leaves with an extended terminal lobe. Most importantly, the species has the ability to produce stolons. Identification To positively identify ''Tiarella austrina'', all of the following key features must be verified (in any order): * Stolon present * Basal leaves usually longer than wide * Basal leaf lobes usually acute-acuminate with the terminal lobe prominently extended * Flowering stem usually with 1–2 leaves or foliaceous bracts The key features listed above are simila ...

Tiarella Polyphylla
''Tiarella polyphylla'' is a species of flowering plant in the family Saxifragaceae. The specific name ''polyphylla'' means "many-leaved". The species is native to Asia, ranging from the eastern Himalayas to China, east Asia, and southeast Asia. It is sometimes called the Asian foamflower. Description ''Tiarella polyphylla'' is a perennial, herbaceous plant with a short, slender rhizome. It has numerous heart-shaped basal leaves, each with a petiole long. There are two or three smaller leaves on the flowering stem. Each flower is small and whitish, with ovate sepals long but with no petals. Taxonomy ''Tiarella polyphylla'' was described by David Don in 1825. Its type specimen was collected by Nathaniel Wallich in Nepal in 1821. The species is relatively constant in morphology and apparently without synonymy. For a long time it was thought that the two North American species ('' Tiarella cordifolia'' and '' Tiarella trifoliata'') were more closely related to each other tha ...

Saxifragaceae
Saxifragaceae is a family of Herbaceous plant, herbaceous Perennial plant, perennial flowering plants, within the core eudicot Order (biology), order Saxifragales. The Taxonomy (biology), taxonomy of the family has been greatly revised and the scope much reduced in the era of Molecular phylogenetics, molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus ''Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are Herbaceous plant, herbaceous Perennial plant, perennials (rarely Annual plant, annual or biennial plant, biennial), sometimes Succulent plant, succulent or Xerophyte, xerophytic, often with perennating rhizomes. The Leaf, leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Don
David Don (21 December 1799 – 15 December 1841) was a Scottish botanist. Biography David Don was born on 21 December 1799 at Doo Hillock, Forfar, Angus, Scotland to Caroline Clementina Stuart, and her husband George Don of Forfar. His older brother was George Don, also a botanist. His father was a curator at the Royal Botanic Garden, Leith Walk, Edinburgh. Don was Professor of Botany at King's College London from 1836 to 1841, and librarian at the Linnean Society of London from 1822 to 1841.

Don) Endl.), Bristlecone Fir (''Pinus bracteata'' D. Don, now ''Abies bracteata'' (D. Don) A. Poit.), Grand Fir (''Pinus grandis'' Douglas ex D. Don; now ''Abies grandis'' (Douglas ex D. Don) Lindl.) and Coulter Pine (''Pinus coulteri'' D. Don), and was the first to treat Sugi (''Cupressus japonica' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
