Stelis, or leach orchids, is a large genus of orchids, with perhaps 500 species. The generic name Stelis is the Greek word for 'mistletoe', referring to the epiphytic habit of these species. These mainly epiphytic plants are widely distributed throughout much of South America, Central America, Mexico, the West Indies and Florida.
The Pleurothallidinae are a neotropical subtribe of plants of the orchid family (Orchidaceae) including 29 genera in more than 4000 species.
Megachilidae is a cosmopolitan family of mostly solitary bees whose pollen-carrying structure is restricted to the ventral surface of the abdomen. Megachilid genera are most commonly known as mason bees and leafcutter bees, reflecting the materials from which they build their nest cells ; a few collect plant or animal hairs and fibers, and are called carder bees, while others use plant resins in nest construction and are correspondingly called resin bees. All species feed on nectar and pollen, but a few are kleptoparasites, feeding on pollen collected by other megachilid bees. Parasitic species do not possess scopae. The motion of Megachilidae in the reproductive structures of flowers is energetic and swimming-like; this agitation releases large amounts of pollen.
Cajeput tree is a common name used for certain classification of tree that has a white spongy bark that is flexible and can easily flake off the trunk. The Cajeput tree is of the genus Melaleuca, native to Australia and is commonly known in North America as the tea tree. The name "Cajeput tree" is primarily used for the species M. cajuputi, M. leucadendra, M. linariifolia, M. viridiflora and M. quinquenervia. Other names for these trees are the paperbark tree, punk tree, or the white bottle brush tree. Similar subtropical trees from the eucalyptus family are evergreens with pointed leaves and white, red or green flowers.
Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark. The grey-green leaves are egg-shaped, and cream or white bottlebrush-like flowers appear from late spring to autumn. It was first formally described in 1797 by the Spanish naturalist Antonio José Cavanilles.
Stelis argentata, commonly known as the silvery stelis, is a species of orchid of the genus Stelis.
Trevoa is a genus of actinorhizal plants; these dicotyledon flora are trees or small shrubs. The genus was first proposed by Miers in 1825, but was not fully described until 1830 by Sir William Jackson Hooker. Genus members are notable for their ability to fix nitrogen. Species of this genus are generally found in the near coastal forests and arid shrubland of South America. Some species are localized in the mountains of central Chile; for example, the species Trevoa trinervis occurs in the La Campana National Park and other proximate areas of central Chile.
Stelis immersa is a species of orchid found from Mexico to northern Venezuela.
Stelis ophioglossoides is a species of orchid found from the Caribbean to northern South America. It is the type species of the genus Stelis.
Stelis ornata is a species of orchid found from Mexico through Guatemala and El Salvador as a miniature epiphyte at elevations of 1500 to 2500 meters above sea level. The plant is characterized by erect ramicauls enveloped by two basal sheaths and carrying a single apical, erect, coriaceous leaf where it blooms on an apical, single successive flowered, 2 inch [4 to 5 cm] long, fractiflex inflorescence that holds the successive opening, single flowers amid or just above the leaves occurring at any time of the year. In cultivation it prefers cool temperatures, shade, and high humidity as well as mounting on tree fern, and good air movement.
Stelis tricardium is a species of orchid occurring from Ecuador to Peru.
Castalin is an ellagitannin. It can be found in oak wood and in Melaleuca quinquenervia leaves.
Grandinin is an ellagitannin. It can be found in Melaleuca quinquenervia leaves and in oaks species like the North American white oak and European red oak. It shows antioxydant activity. It is an astringent compound. It is also found in wine, red or white, aged in oak barrels.
Oxyops vitiosa is a species of weevil in the family Curculionidae. Common names include the melaleuca leaf weevil and the melaleuca snout beetle. It feeds on the leaves and shoots of the broad-leaved paper bark tree, Melaleuca quinquenervia, which is endemic to Australia where it grows on seasonally inundated plains and swampland, and was introduced into Florida in order to help drain flooded portions of the Everglades.
Stelis is a genus of kleptoparasitic bees in the family Megachilidae. There are at least 100 described species in Stelis.
Stelis costalis is a species of bee in the family Megachilidae. It is found in Central America and North America.
Stelis lateralis is a species of bee in the family Megachilidae. It is found in Central America and North America.
Stelis gracilis is a species of leach orchid, which is one of the largest genera in the orchid family, with over 600 species. Stelis gracilis are small epiphytes with greenish-white flowers in raceme inflorescences. This rare species of orchid is found in tropical rainforests in North and Central America. It was first described by the American botanist Oakes Ames in 1908.
