Melica Longiflora
''Melica longiflora'' is a grass species in the family Poaceae that is endemic to Chile where it can be found from Coquimbo to Talca. Description The species is perennial and is caespitose as well. The culms are either ascended or rambled, are long and in diameter. The leaf-sheaths are tubular, retrorsely scabrous, and are either glabrous or pilose on the bottom. The leaf-blades are aromatic, are long and wide. Just like leaf-sheaths they are scabrous, but unlike them they are hairy, glabrous or pubescent, and are rough on both sides. Their margins are glabrous, scabrous or ciliated. The panicle is open, pyramidal, and is long. The main panicle branches are contracted and have scaberulous or smooth axis, while the other panicle branches are secund. Spikelets are solitary with fertile spikelets being pedicelled, pedicels of which are ciliated, curved, filiform, scabrous and hairy on top. The spikelets are elliptic, are long, and have 2 fertile florets which are diminished a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palea (botany)
A spikelet, in botany, describes the typical arrangement of the flowers of grasses, sedges and some other Monocots. Each spikelet has one or more florets. The spikelets are further grouped into panicles or spikes. The part of the spikelet that bears the florets is called the rachilla. In grasses In Poaceae, the grass family, a spikelet consists of two (or sometimes fewer) bracts at the base, called glumes, followed by one or more florets. A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The perianth is reduced to two scales, called lodicules, that expand and contract to spread the lemma and palea; these are generally interpreted to be modified sepals. The flowers are usually hermaphroditic—maize being an important exception—and mainly anemophilous or wind-pollinated, although insects occasionally play a role. Lemma Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puya Chilensis
''Puya chilensis'' is a terrestrial bromeliad originating from the arid hillsides of Chile. Description An evergreen perennial, it forms large, dense rosettes of grey-green, strap-like leaves edged with hooked spines. The green or yellow flowers are borne on spikes which resemble a medieval mace, and stand up to high. Spreading by offsets, ''Puya chilensis'' can colonise large areas over time. Growth is slow and plants may take 20 years or more to flower. The outer two-thirds of the leaf blade bears outward-pointing spines which may be an adaptation to prevent herbivores from reaching the center of the plant. The plant is believed to be hazardous to sheep and birds which may become entangled in the spines of the leaves. If the animal dies, the plant may gain nutrients as the animal decomposes nearby, though this has not been confirmed. For this reason, ''Puya chilensis'' has earned the nickname "sheep-eating plant". If true, this would make ''Puya chilensis'' a protocarnivorou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peumus Boldus
''Peumus boldus'', the only species in the genus ''Peumus'', is commonly known as boldo (from the Mapuche name ''foḻo''). This tree of the family Monimiaceae is natively endemic to the central region of Chile, occurring from 33° to 40° southern latitude. Boldo has also been introduced to Europe and North Africa, though it is not often seen outside botanical gardens. Due to its common name (boldo), mainly in Latin America, it is usually confused with the ''Plectranthus ornatus'' species, known as ''falso boldo'' ("fake ''boldo''"), ''boldo paraguayo'' or ''boldo rastrero'', which has led to confusion about the uses, properties and toxicity of both species. Description ''Boldo'', together with ''litre'', ''quillay'', ''peumo'', ''bollén'' and other indigenous plants, is a characteristic component of the sclerophyllous forests endemic to central Chile. Its leaves, which have a strong, woody and slightly bitter flavor and camphor-like aroma, are used for culinary purposes, ...

Lithraea Caustica
''Lithraea caustica'' (commonly known as the litre tree, and historically as llithi or liti) is a species of flowering plants in the soapberry family Anacardiaceae. This plant is Endemism, endemic to central Chile; an example occurrence is in the area of La Campana National Park and Cerro La Campana. The tree is a well known allergenic and can cause a rash of the skin, the effects and susceptibility of which can vary greatly from person to person. Description Litre is evergreen, with oval leaves with a smooth or undulating border. It can grow to be a full tree when undisturbed; the tree-like formation was formerly common, but it is now most frequently found as a shrub due to changing patterns of land use. It has dense leaves due to the high levels of lignin and cellulose. It grows large, underground burls from which new growth with emerge after it is cut or burned down; it shares this trait with most of the woody plants in its region.

Baccharis Linearis
''Baccharis linearis'', the romerillo or Chilean little rosemary, is a common shrub in Central Chile. It is frequently found in old field after agriculture. Cecidia or galls caused by the fruit fly ''Rachiptera limbata'' grow as white, spongy and globose tissues on the twigs of the plant. Description This densely branched, shrubby species reaches heights of 1-3 m. The branches are erect. Young branches have a green bark, which becomes reddish brown with age. The linear, sessile, rarely dentate leaves are 0-30 mm long and 0-2.5 mm wide. Dentate leaves are observed on young plants, but this characteristic is lost in later ontogenic stages, in which only linear leaves devoid of any dentation are formed. The capitula are formed in groups. In male plants they are 3-4.5 mm wide and in female plants they are 2-3 mm wide. They are attached to the branches by 3-8 mm long peduncles. Natural hybridisation This species is part of a homoploid hybrid swarm involving ''Baccharis macraei ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Caven
''Vachellia caven'' (Roman cassie, , aromo criollo, caven, , , espinillo, espinillo de baado, espino, espino maulino) is an ornamental tree in the family Fabaceae. ''Vachellia caven'' is native to Argentina, Bolivia, Chile, Paraguay, and Uruguay. It grows four to five metres tall and bears very stiff and sharp white thorns up to 2 cm in length. It blooms in spring, with bright yellow flower clusters in diameter.

Trichocereus
''Echinopsis'' is a large genus of cacti native to South America, sometimes known as hedgehog cactus, sea-urchin cactus or Easter lily cactus. One small species, ''E. chamaecereus'', is known as the peanut cactus. The 128 species range from large and treelike types to small globose cacti. The name derives from ''echinos'' hedgehog or sea urchin, and ''opsis'' appearance, a reference to these plants' dense coverings of spines. They are remarkable for the great size, length of tube, and beauty of their flowers, which, borne upon generally small and dumpy stems, appear much larger and more attractive than would be expected. Taxonomy Studies in the 1970s and 1980s resulted in several formerly separate genera being absorbed into ''Echinopsis'': Some have proposed merging ''Rebutia'' as well. Like several other taxonomic changes in Cactaceae, this one has not been universally accepted. Amateur and professional growers still use names like ''Echinopsis'' (in the older sense), '' ...

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Andes
The Andes, Andes Mountains or Andean Mountains (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long, wide (widest between 18°S – 20°S latitude), and has an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto and La Paz. The Altiplano plateau is the world's second-highest after the Tibetan plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes Mountains are the highest m ...
