Sterculia Apetala
''Sterculia apetala'', the Panama tree, is a species of flowering plant in the family Malvaceae. It is found in Florida, southern Mexico, Central America, and northern South America, and has been introduced to the Caribbean islands. ''Sterculia apetala'' is recognized as the national tree of the Republic of Panama. Description ''Sterculia apetala'' is perennial and deciduous. Trunks are straight, cylindrical, and have large buttresses at the base. Height ranges from . Leaves are alternate, palmate with five lobes, and cluster densely at the end of branches. Including the petiole, leaf length ranges from . Flowers are purple and yellow, and have five sepals. ''S. apetala'' flowers have no petals; structures that resemble them are in fact sepals. Flower diameter ranges between . These flowers are unisexual, meaning there are distinct male and female individuals used for reproduction. Fruit are compounds of up to five follicles, stemming from peduncles that can reach as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Orinoco
The Orinoco () is one of the longest rivers in South America at . Its drainage basin, sometimes known as the Orinoquia, covers approximately 1 million km2, with 65% of it in Venezuela and 35% in Colombia. It is the List of rivers by discharge, fourth largest river in the world by Discharge (hydrology), discharge volume of water (39,000 m3/s at Orinoco Delta, delta) due to the high precipitation throughout its catchment area (ca 2,300 mm/a). The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The environment and wildlife in the Orinoco's basin are extremely diverse. Etymology The river's name is derived from the Warao language, Warao term for "a place to paddle", itself derived from the terms ''güiri'' (paddle) and ''noko'' (place) i.e. a navigable place. History The mouth of the Orinoco River at the Atlantic Ocean was documented by Christopher Columbus on 1 August 1498, during his Christo ...

Cyclopropene Fatty Acid
Cyclopropane fatty acids (CPA) are a subgroup of fatty acids that contain a cyclopropane group. Although they are usually rare, the seed oil from lychee contains nearly 40% CPAs in the form of triglycerides. Biosynthesis CPAs are derived from unsaturated fatty acids by cyclopropanation. The methylene donor is a methyl group on S-adenosylmethionine (SAM). The conversion is catalyzed by cyclopropane-fatty-acyl-phospholipid synthase. The mechanism is proposed to involve transfer of a CH3+ group from SAM to the alkene, followed by deprotonation of the newly attached methyl group and ring closure. Cyclopropene fatty acids Cycloprop''e''ne fatty acids are even rarer molecules. The best-known examples are malvalic acid and sterculic acid. A triglyceride made of 3 sterculic acid molecules esterified with glycerol is present in ''Sterculia foetida'' seed oil (in amounts greater than 60%) and at low levels in the seed oil of other species of Malvaceae (~12%), cottonseed oil (~1%) ...

Flora Of Western South America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Flora Of Trinidad And Tobago
Trinidad and Tobago are continental islands with a geologically very recent history of direct land bridge connection to South America. As a result, unlike most of the Caribbean Islands, Trinidad and Tobago supports a primarily South American flora (plants), flora and fauna (animals), fauna and has greater diversity of plant and animal species than the Antilles. However, rates of endemic (ecology), endemism are lower than in the rest of the Caribbean because there has been less time for genetic isolation from mainland populations. Specifically, a land bridge to Venezuela existed fairly recently in Trinidad, allowing fewer opportunities for speciation than in Tobago, as well as a lot of overlap in biodiversity with the South American mainland. Trinidad is nearer to mainland South America and has been directly connected to the mainland via land bridges more often and for longer periods than Tobago. This, as well as Trinidad's larger size and more varied topography and hydrology comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ornamental Trees
Ornamental plants or ''garden plants'' are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost all types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents, aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and ''foliage plants''. The cultivation of ornamental plants comes under floriculture and tree nurseries, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyacinth Macaw
The hyacinth macaw (''Anodorhynchus hyacinthinus''), or hyacinthine macaw, is a parrot native to central and eastern South America. With a length (from the top of its head to the tip of its long pointed tail) of about one meter it is longer than any other species of parrot. It is the largest macaw and the largest flying parrot species. While generally easily recognized, it could be confused with the smaller Lear's macaw. Habitat loss and the trapping of wild birds for the pet trade have taken a heavy toll on their population in the wild, so the species is classified as Vulnerable species, Vulnerable on the International Union for Conservation of Nature's IUCN Red List, Red List, and it is protected by its listing on Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Taxonomy It is one of two extant and one probably extinct species of the South American macaw genus ''Anodorhynchus''. English physician, ornithologist, and ...
