Halesia
''Halesia'', also known as silverbell or snowdrop tree, is a small genus of four or five species of deciduous large shrubs or small trees in the family Styracaceae. Range They are native to eastern Asia (southeast China) and eastern North America (southern Ontario, Canada south through Florida and eastern Texas, United States). Description They grow to tall (rarely to ), and have alternate, simple ovate leaves 5–16 cm long and 3–8 cm broad. The flowers are pendulous, white or pale pink, produced in open clusters of 2–6 flowers, each flower being 1–3 cm long. The fruit is a distinctive, oblong dry drupe 2–4 cm long. All species except ''H. diptera'' have four narrow longitudinal ribs or wings on fruit; ''diptera'' only has two, making it the most distinctive of the group.

Halesia Carolina
''Halesia carolina'', commonly called Carolina silverbell or little silverbell, is a species of flowering plant in the family Styracaceae, native to the southeastern United States. Description It is a vigorous, fast-growing deciduous shrub or tree growing to tall by broad, bearing masses of pendent, bell-shaped white flowers which appear in spring before the leaves. The flowers are followed by green, four-winged fruit. The leaves turn yellow in autumn. Range The range of little silverbells is very restricted. It is principally in the panhandle of Florida, with isolated smaller outlier populations in South Carolina, Georgia, Alabama, Mississippi. In the cited reference, this species is referred to as ''Halesia parviflora''. The "champion" ''Halesia carolina'' on the 2015 American Forests' National Register of Champion Trees is quite removed from its natural range, being situated in Roxbury, New Hampshire.

Halesia Monticola
''Halesia'' (''tetraptera'' var.) ''monticola'', the mountain silverbell, is a species of flowering plant in the small family Styracaceae. This large deciduous shrub was originally included in '' H. carolina'', but was identified first as a subspecies by Rehder in 1914, then as a species by Sargent in 1921. More recently, some authoritative sources regard it only as a subspecies or variety, while other authoritative sources regard it as a species, as it is treated here. Description ''H. monticola'' is much larger than either the little silverbell or common silverbell (var. ''tetraptera''), and is the largest member of the genus. It is known to grow 34 meters tall in the Great Smoky Mountains. Another important difference is that ''monticola'' has significantly larger flowers than either ''H. carolina'' or ''H. tetraptera''. Range The silverbell tree grows mostly in the southern Appalachian Mountains and into southern Alabama and Georgia, with small outlying populations up to a ...

Halesia Diptera
''Halesia diptera'', the two-wing silverbell or two-winged snowdrop tree, is a species in the family Styracaceae, native to the southeastern United States from South Carolina and Florida west to eastern Texas. It is cultivated as an ornamental tree. Description It is a large shrub or small tree reaching 4–8 m tall. The leaves are deciduous, 6–12 cm long and 4–7 cm broad. The flowers are white, 2-2.5 cm long, produced in clusters of 3–6 together. The fruit is a dry (non-fleshy) drupe with two wings down the sides; this distinguishes it from the other species of ''Halesia ''Halesia'', also known as silverbell or snowdrop tree, is a small genus of four or five species of deciduous large shrubs or small trees in the family Styracaceae.

Styracaceae
The Styracaceae are a small family of flowering plants in the order Ericales, containing 12 genera and about 160 species of trees and shrubs. The family occurs in warm temperate and subtropical regions of the Northern Hemisphere. The family is characterised by spirally arranged simple leaves with no stipules; symmetrical white flowers with a corolla of two to five (sometimes seven) fused petals; and the fruit usually is a dry capsule, sometimes winged, less often a fleshy drupe, with one or two seeds. Most are large shrubs to small trees 3–15 m tall, but ''Halesia monticola'' (''H. carolina'' var. ''monticola'') is larger, with trees 39 m tall known in the Great Smoky Mountains National Park in North Carolina. Genera Several genera include species popular as ornamental trees valued for their decorative white flowers. Benzoin resin, used in herbal medicine and perfumes, is extracted from the bark of ''Styrax'' species. ;Genera *'' Alniphyllum'' Matsum. (three species) *'' Br ...

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about fiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Ellis (naturalist)
John Ellis ( – 15 October 1776) aka Jean Ellis was a British linen merchant and naturalist. Ellis was the first to have a published written description of the Venus flytrap and its botanical name. Ellis specialised in the study of corals. He was elected a member of the Royal Society in 1754 and in the following year published ''An essay towards the Natural History of the Corallines''. He was awarded the Copley Medal in 1767. He was elected to the American Philosophical Society in 1774. His ''A Natural History of Many Uncommon and Curious Zoophytes'', written with Daniel Solander, was published posthumously in 1776. Ellis was appointed Royal Agent for British West Florida in 1764, and for British Dominica in 1770. He exported many seeds and native plants from North America to England. He corresponded with many botanists, including Carl Linnaeus. Taxonomist Venus's Fly-trap A royal botanist, William Young imported living plants of the Venus flytrap to England. They were ...

Drupe
In botany, a drupe (or stone fruit) is an indehiscent fruit in which an outer fleshy part ( exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pit'', ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. These fruits usually develop from a single carpel, and mostly from flowers with superior ovaries ( polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, lignified stone is derived from the ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a different definition of ''berry''. Other fleshy fruits may have a stony enclosure that comes from the seed coat surrounding the seed, but such fruits are not drupes. Flowering plants that produce drupes include coffee, jujube, mango ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Phylogenetics
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and do ...
