Fraxinus () is a genus of flowering plants in the olive and lilac family, Oleaceae. It contains 45-65 species of usually medium to large trees, mostly deciduous though a few subtropical species are evergreen. The tree's common English name, ash, goes back to the Old English ?sc, while the generic name originated in Latin. Both words also meant "spear" in their respective languages.

The seeds, popularly known as keys or helicopter seeds, are a type of fruit known as a samara. Rowans or Mountain Ashes are unrelated to true ashes and belong to the Genus Sorbus though the leaves and buds are superficially similar. [more]

A number of these species (particularly Helenium autumnale) are commonly known as sneezeweed based on the former use of its dried leaves in making snuff, inhaled to cause sneezing that would supposedly rid the body of evil spirits. [more]
The genus Heliamphora ( or /hi?li'?mf?r?/; Greek: helos "marsh" and amphoreus "amphora") contains 23 species of pitcher plants endemic to South America. The species are collectively known as sun pitchers, based on the mistaken notion that the heli of Heliamphora is from the Greek helios, meaning "sun". In fact, the name derives from helos, meaning marsh, so a more accurate translation of their scientific name would be marsh pitcher plants. Species in the genus Heliamphora are carnivorous plants that consist of a modified leaf form that is fused into a tubular shape. They have evolved mechanisms to avoid completely filling up with water and attract, trap, and kill insects. At least one species (H. tatei) produces its own proteolytic enzymes that allows it to digest its prey without the help of symbiotic bacteria. [more]
The Helianthus L. genus comprises 67 species and several subspecies in the Asteraceae family, all of which are native to North America, with some species (particularly Helianthus annuus (sunflower) and Helianthus tuberosus (Jerusalem artichoke)) cultivated in Europe and other parts of the world as food crops and ornamental plants.

Hippeastrum is a genus of about 90 species and 600+ hybrids and cultivars of bulbous plants in the family Amaryllidaceae, subfamily Amaryllidoideae, native to tropical and subtropical regions of the Americas from Argentina north to Mexico and the Caribbean. Some species are grown for their large showy flowers. For many years there was confusion amongst botanists over the generic names Amaryllis and Hippeastrum, one result of which is that the common name "amaryllis" is mainly used for cultivars of this genus, which are widely used as indoor flowering bulbs. The generic name Amaryllis applies to bulbs from South Africa, usually grown outdoors. [more]
The sea-buckthorns (Hippophae L.) are deciduous shrubs in the genus Hippophae, family Elaeagnaceae. The name sea-buckthorn is hyphenated here to avoid confusion with the buckthorns (Rhamnus, family Rhamnaceae). It is also referred to as sandthorn, sallowthorn, or seaberry. [more]
Hosta (, syn.: Funkia) is a genus of about 23?45 species of lily-like plants in the family Asparagaceae, subfamily Agavoideae, native to northeast Asia. They have been placed in their own family, Hostaceae (or Funkiaceae); like many 'lilioid monocots', they were once classified in the Liliaceae. The scientific name is also used as the common name; in the past they were also sometimes called the Corfu Lily, the Day Lily, or the Plantain lily, but these terms are now obsolete. The name Hosta is in honor of the Austrian botanist Nicholas Thomas Host. The Japanese name Giboshi is also used in English to a small extent. The rejected generic name Funkia, also used as a common name, can be found in some older literature. [more]

[more]

Loranthus is a genus of mostly parasitic plants that grow on the branches of woody trees. It belongs to the family Loranthaceae, the showy mistletoe family. In most earlier systematic treatments it contains all mistletoe species with bisexual flowers, though some species have reversed to unisexual flowers, while most modern systematists treat it as a monotypic genus with the only species Loranthus europaeus Jacq. - the summer mistletoe or European yellow mistletoe. In contrast to the wellknown European or Christmas mistletoe (Viscum album L., Santalaceae or Viscaceae) this species is deciduous. The systematic situation of Loranthus is not entirely clear, and some showy mistletoes in Asia may be true parts of this genus. [more]
Machaeranthera is a genus of flowering plants in the daisy family which are known by the common name tansyaster. Tansyasters are variable in appearance. Some are small singular wildflowers while others are sprawling shrubs. Several species easily hybridize with each other as well, making identification difficult. In general, members of the genus may be identified by the sharp-pointed, dagger-shaped anthers in the disc florets at the center of the flower. The flower heads are usually daisylike and are usually a shade of purple or blue, but may be pink, yellow, or white. Tansyasters are native to western North America. [more]
Madia is a genus of annual or perennial usually aromatic herbs, which have yellow flowers, in the family Asteraceae (sunflower family). They are sometimes known as tarweeds. The 21 species in this genus are native to western North America and southwestern South America. The name Madia is derived from a Chilean name ("Madi") for one of the members of the genus. [more]
Mahonia is a genus of about 70 species of evergreen shrubs in the family Berberidaceae, native to eastern Asia, the Himalaya, North America and Central America. They are closely related to the genus Berberis. Botanists disagree on the acceptability of the genus name Mahonia. Several authorities argue plants in this genus should be included in the genus Berberis because several species in both genera are able to hybridize, and because when the two genera are looked at as a whole, there is no definite morphological separation. Mahonia typically have large, pinnate leaves 10?50 cm long with 5-15 leaflets, and flowers in racemes (5?20 cm long). [more]
Malcolmia is a genus from the family Brassicaceae. Species from this genus are native to Europe and Africa. [more]

Raphanus is a genus within the flowering plant family Brassicaceae. Two or three species are currently classified in Raphanus. They include the cultivated radish, Raphanus sativus and the common wild radish or jointed charlock, R. raphanistrum.

Substantial numbers of other species in the genus have been proposed at various times, but almost all are currently regarded as varieties of R. sativus, while a few are treated as varieties of R. raphanistrum or are not accepted as well-described species. Examples are R. raphanistrum ssp. landra and R. raphanistrum ssp. maritimus (Sea Radish). [more]

Silphium (also known as silphion or laser) was a plant that was used in classical antiquity as a rich seasoning and as a medicine. It was the essential item of trade from the ancient North African city of Cyrene, and was so critical to the Cyrenian economy that most of their coins bore a picture of the plant (illustration, right). The valuable product was the plant's resin (laser, laserpicium, or lasarpicium). [more]
