Alfaroa Manningii
''Alfaroa manningii'', or gavilán colorado, is a valued lumber tree of the Walnut family endemic to the premontane Costa Rican rain forest. The specific epithet honors the American botanist Wayne Eyer Manning (1899–2004). Description ''Alfaroa manningii'' grows to 24 m tall, with a diameter at breast height up to 0.9 m, and small to medium large buttress roots. The bark is reddish brown externally, and yellow orange internally. The sapwood is white, the heartwood pink. The opposite pinnately compound leaves bear eight to twelve (rarely six to eighteen) opposite leaflets. The petiole of the leaf is 5–9 cm long, and the petioles of the leaflets are 2–5 mm long. The entire leaf may be up to 3 m long. (The first two leaves on a seedling are simple, and are followed by several alternate compound leaves.) The upright female inflorescence is born terminally on the current year's growth, containing 40 to 50 blossoms. The male inflorescence is a catkin, up to ...

Juglandaceae
The Juglandaceae are a plant family known as the walnut family. They are trees, or sometimes shrubs, in the order Fagales. Members of this family are native to the Americas, Eurasia, and Southeast Asia. The nine or ten genera in the family have a total of around 50 species, and include the commercially important nut-producing trees walnut (''Juglans''), pecan (''Carya illinoinensis''), and hickory (''Carya''). The Persian walnut, '' Juglans regia'', is one of the major nut crops of the world. Walnut, hickory, and gaulin are also valuable timber trees while pecan wood is also valued as cooking fuel. Description Members of the walnut family have large, aromatic leaves that are usually alternate, but opposite in '' Alfaroa'' and '' Oreomunnea''. The leaves are pinnately compound or ternate, and usually 20–100 cm long. The trees are wind-pollinated, and the flowers are usually arranged in catkins. The fruits of the Juglandaceae are often confused with drupes but are ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rain Forest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere.

Wayne Eyer Manning
Wayne Eyer Manning (December 4, 1899 – February 8, 2004) was an American horticulturist and botanist. Biography In 1920, Manning obtained his Bachelor of Sciences from Oberlin College. In 1926 he received his Ph.D. from Cornell University. His dissertation research was based on the study of the floral anatomy of Juglandaceae. Manning was a professor at Cornell for one year and then began teaching at the University of Illinois at Urbana–Champaign. He then became a professor at Smith College where he taught from 1928 until 1941. In 1945, he began teaching at Bucknell University. He remained at this university until his retirement in 1968.

Diameter At Breast Height
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately above ground. Global variation and scientific precision The height can make a substantial difference to the measured diameter. In the United States, DBH is typically measured at above ground. In some countries, such as Australia, New Zealand, Burma, India, Malaysia, and South Africa, breast height diameter has historically been measured at a height of , but because of much active research into allometrics that are being applied to trees and forests, the convention of is more appropriate. Ornamental trees are usually measured at 1.5 metres above ground. Some authors have argued that the term DBH should be abolish ...

Sessility (botany)
In botany, sessility (meaning "sitting", in the sense of "resting on the surface") is a characteristic of plant organs such as flowers or leaves that have no stalk. Plant parts can also be described as subsessile, that is, not completely sessile. A sessile flower is one that lacks a pedicel (botany), pedicel (flower stalk). A flower that is not sessile is Pedicel (botany), pedicellate. For example, the genus ''Trillium'' is partitioned into multiple subgenera, the sessile-flowered trilliums (Trillium#Subgenus Sessilia, ''Trillium'' subgen. ''Sessilia'') and the pedicellate-flowered trilliums. The term "sessility" is also used in mycology to describe a fungal sporocarp (fungi), fruit body that is attached to or seated directly on the surface of the substrate (biology), substrate, lacking a supporting stipe (mycology), stipe or pedicel (botany), pedicel.

Pedicel (botany)
In botany, a pedicel is a stem that attaches a single flower to the inflorescence. Such inflorescences are described as ''pedicellate''. The stalk at the base of a leaf is called a petiole. Description Pedicel refers to a structure connecting a single flower to its inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin ''pediculus'', meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts.

Cartago, Costa Rica
Cartago () is the head city of Cartago canton of the Cartago Province, and is composed of the Oriental and Occidental districts as stated in the administrative divisions of Costa Rica. It was the capital of Costa Rica from 1574 to 1824. History Founded in 1563 by Juan Vasquez de Coronado, it was the first successful establishment in Costa Rica. The city was granted a coat of arms by King Philip II of Spain in 1565, and the title of Muy Noble y Muy Leal ("Very Noble and Very Loyal") by the Cortes (Spanish Parliament) in 1814. It served as the first capital of Costa Rica until 1823, when Republican leader Gregorio José Ramírez, moved the capital to the bigger city of San José, because Cartago wanted to unite the newly independent province of Costa Rica to the Iturbide's Mexican Empire while San Jose and Alajuela supported a Republican system. The city was severely damaged by major earthquakes in 1822, 1841 and 1910. In 1963, a volcanic eruption of Irazu Volcano which ...

Alfaroa
''Alfaroa'' is a genus of evergreen trees in the Juglandaceae family of the Fagales, growing in montane and submontane tropical rain forests in Central America. The wood is characterized by solid pith, pink heartwood, and vessels with scalariform perforations, as well as simple perforations. Description The (usually pinnately compound) leaves are evergreen and lack stipule In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole (botany), petiole). They are primarily found among dicots and rare among monocots. Stipules are considered part ...s. They are alternate, rarely opposite. The plants are monoecious, the male flowers being in lateral panicles (several pairs of catkins on an inflorescence) and the female flowers born terminally either in a single spike or in a hermaphroditic panicle including several paired male catkins.
