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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Specimen
In biology, a type is a particular wiktionary:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the ...

Mitella Diphylla
''Mitella diphylla'' (twoleaf miterwort, two-leaved mitrewort, or bishop's cap) is a clump forming, open woodland plant native to northeast and midwest regions of North America. Description Miterwort grows from a rhizomatous root system with fibrous roots. Leaves are coarsely toothed with 3-5 shallow lobes. Most leaves are basal, and there is one opposite pair of stemless leaves on each flower stalk. Tiny flowers with finely divided, lacy white petals are produced in mid-spring in racemes on stems growing from tall. The seeds are tiny, , produced in small green cups, formed from the sepals of the flower, and when ripe are shiny and black. They are spread when raindrops hit the cups and splash the seeds out. It grows in high quality mesic forests on moist, mossy ledges and north-facing slopes. The Latin specific epithet ''diphylla'' means two-leaved and is in reference to the non-basal leaves. Ecology The flowers produce both pollen and nectar. Due to their small size, they a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiarella Wherryi
''Tiarella wherryi'' is a species of flowering plant in the family Saxifragaceae. The specific name ''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 Nautila
''Tiarella nautila'' is a species of flowering plant in the family Saxifragaceae. The specific name ''nautila'' alludes to its sail-like stem leaves. Accordingly, it is sometimes called the sail-leaf foamflower. The species is narrowly endemic to the Blue Ridge Mountains in the southeastern United States. Description ''Tiarella nautila'' 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 lacks the ability to produce stolons. Identification To positively identify ''Tiarella nautila'', 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 usually with leaves or foliaceous bracts If the plant in question has a stolon, it is not ''Tiarella nautila''. In that case, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiarella Stolonifera
''Tiarella stolonifera'' is a species of flowering plant in the 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, 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 flowering, the orientation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 sim ...

Stolon
In biology, stolons (from Latin '' stolō'', genitive ''stolōnis'' – "branch"), also known as runners, are horizontal connections between organisms. They may be part of the organism, or of its skeleton; typically, animal stolons are external skeletons. In botany In botany, stolons are stems which grow at the soil surface or just below ground that form adventitious roots at the nodes, and new plants from the buds. Stolons are often called runners. Rhizomes, in contrast, are root-like stems that may either grow horizontally at the soil surface or in other orientations underground. Thus, not all horizontal stems are called stolons. Plants with stolons are called stoloniferous. A stolon is a plant propagation strategy and the complex of individuals formed by a mother plant and all its clones produced from stolons form a single genetic individual, a genet. Morphology Stolons may or may not have long internodes. The leaves along the stolon are usually very small, but in a few ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stamens
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...
