Glossary Of Leaf Morphology
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labellum (botany)
In botany, the labellum (or lip) is the part of the flower of an orchid or ''Canna'', or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them. ''Labellum'' (plural: ''labella'') is the Latin diminutive of ''labrum'', meaning lip. The labellum is a modified petal and can be distinguished from the other petals and from the sepal A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 The term ''sepalum'' was coined ...s by its large size and its often irregular shape. It is not unusual for the other two petals of an orchid flower to look like the sepals, so that the labellum stands out as distinct. Bailey, L. H. ''Gentes Herbarum: Canna x orchiodes''.

Spiranthes Graminea
''Spiranthes graminea'' or the Canelo lady's tresses is a species of orchid found in Mexico and Central America. Distribution and habitat ''Spiranthes graminea'' has been found in Belize, Guatemala, Honduras, Mexico and Nicaragua. Taxonomy The species was published in 1840 by John Lindley, under the current name of ''Spiranthes graminea''. Plants collected in 1968 in Arizona were first thought to be ''Spiranthes graminea'' (and are still listed by some publications as occurring in the US), but the plants found in the US were moved to their own species in 1990, ''Spiranthes delitescens ''Spiranthes delitescens'' is a rare species of orchid known by the common names reclusive lady's tresses, Canelo Hills lady's tresses, and Madrean lady's tresses.

Spiranthes Laciniata
''Spiranthes laciniata'', the lacelip ladies' tresses is a terrestrial orchid endemic to the south eastern United States. Description ''Spiranthes laciniata'' plants are a tall species of ''Spiranthes'' reaching a height of 20–95 cm, with up to 5 basal leaves persisting through anthesis. The flowers are white to cream-white and arranged in a spiral around the stem. The lip is usually yellow in the center. Bloom time is from May to (at its northern range) September. Distribution and habitat ''Spiranthes laciniata'' is native to the southeastern coastal plains, from Texas in the south all the way to New Jersey in the north. It is a wetland plant and grows in swamps and marshes, sometimes even in standing water. Taxonomy The ''Spiranthes laciniata'' name was first published by Oakes Ames in 1905, after John Kunkel Small had described the plants in 1903 as ''Gyrostachys laciniata''.

Sierra Madre Oriental
The Sierra Madre Oriental () is a mountain range in northeastern Mexico. The Sierra Madre Oriental is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America, and Antarctica. Setting Spanning the Sierra Madre Oriental runs from the Rio Grande on the border between Coahuila and Texas south through Nuevo León, southwest Tamaulipas, San Luis Potosí, Querétaro, and Hidalgo to northern Puebla, where it joins with the east-west running Eje Volcánico Transversal of central Mexico. The northernmost are the Sierra del Burro and the Sierra del Carmen which reach the border with the United States at the Rio Grande. North of the Rio Grande, the range continues northwestward into Texas and beyond as the Davis and Guadalupe Ranges.

Orchids Of Mexico
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are '' Bulbophyllum'' (2,000 species), '' Epidendrum'' (1,500 species), '' Dendrobium'' (1,400 species) and '' Pleurothallis'' (1,000 species). It also includes '' Vanilla'' (the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
