Sabal Sp
''Sabal'' is a genus of New World palms (or fan-palms). Currently, there are 17 recognized species of ''Sabal'', including one hybrid species. Distribution The species are native to the subtropical and tropical regions of the Americas, from the Gulf Coast/South Atlantic states in the Southeastern United States, south through the Caribbean, Mexico, and Central America to Colombia and Venezuela. Description Members of this genus are typically identified by the leaves which originate from a bare, unarmed petiole in a fan-like structure. All members of this genus have a costa (or midrib) that extends into the leaf blade. This midrib can vary in length; and it is due to this variation that leaf blades of certain species of ''Sabal'' are strongly curved or strongly costapalmate (as in ''Sabal palmetto'' and ''Sabal etonia'') or weakly curved (almost flattened), weakly costapalmate (as in ''Sabal minor''). Like many other palms, the fruit of ''Sabal'' are drupe, that typically ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sabal Palmetto
''Sabal palmetto'' (, ''Help:Pronunciation respelling key, SAY-bəl''), also known as cabbage palm, cabbage palmetto, sabal palm, blue palmetto, Carolina palmetto, common palmetto, Garfield's tree, and swamp cabbage, is one of 15 species of Sabal, palmetto Arecaceae, palm. It is native to the Southeast United States, the Yucatán Peninsula in Mexico, the West Indies, and the Bahamas. Description ''Sabal palmetto'' grows up to tall, with the tallest on record measuring at 93 feet tall. Starting at half to two-thirds the height, the tree develops into a rounded, costapalmate fan of numerous leaflet (botany), leaflets. A costapalmate leaf has a definite costa (midrib), unlike the typical palmate or fan leaf, but the leaflets are arranged radially like in a palmate leaf. All costapalmate leaves are about across, produced in large compound panicles up to in radius, extending out beyond the leaves. The fruit is a black drupe about long containing a single seed. It is extremely Halo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamaerops
''Chamaerops'' is a genus of flowering plants in the family Arecaceae. It contains only one species, ''Chamaerops humilis'', variously called European fan palm or the Mediterranean dwarf palm. It is one of the most cold-hardy palms and is used in landscaping in temperate climates. Taxonomy Apart from the universally accepted ''Chamaerops humilis,'' there are a few potential taxa of unresolved status, plus numerous species synonymised under ''Chamaerops humilis''. The genus ''Chamaerops'' is closely related to the genus ''Trachycarpus''. The genera differ in that ''Trachycarpus'' lacks the clumping habit (only forms single stems without basal suckers), the spiny leaf stems (spineless in ''Trachycarpus''), and in small details of the flower anatomy. Subspecies The species ''Chamaerops humilis'' itself has two accepted varieties as follows: *''Chamaerops humilis'' var. ''argentea'' André (syn. ''C. h.'' var. ''cerifera'') – "Atlas mountains palm" of Northwest Africa. Leaves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sabal Causiarum
''Sabal causiarum'', commonly known as the Puerto Rico palmetto or Puerto Rican hat palm, is a species of palm which is native to Hispaniola (in both the Dominican Republic and Haiti), Puerto Rico, and the British Virgin Islands. As its common and scientific names suggest, its leaves are used in the manufacture of "straw" hats. Description ''Sabal causiarum'' is a fan palm with solitary, very stout stems, which grows up to tall and in diameter. Plants have 20–30 leaves, each with 60–120 leaflets. The inflorescences, which are branched, arching or pendulous, and longer than the leaves, bear globose, black fruit. The fruit are in diameter; fruit size and shape are the main characteristics by which this species differs from ''Sabal domingensis''. Taxonomy ''Sabal'' is placed in the subfamily Coryphoideae and the tribe Sabaleae. As of 2008, there appear to be no molecular phylogenetic studies of ''Sabal'' and the relationship between ''S. causiarum'' and the rest of the ...

Sabal Domingensis
''Sabal domingensis'', the Hispaniola palmetto, is a species of Arecaceae, palm which is native to Hispaniola (in both the Dominican Republic and Haiti) and Cuba. Description ''Sabal domingensis'' is a fan palm with solitary, very stout stems, which grows up to tall and in diameter. Plants have 20–30 leaves, each with about 90 leaflets.

Sabal Miamiensis
''Sabal miamiensis'', the Miami palmetto, is a rare plant species endemic to Dade County, Florida, in the vicinity of the city of Miami. Taxonomy The formal description of this as a new species was published in 1985, based largely on specimens collected in 1901. ''Sabal miamiensis'' is closely related to '' S. etonia, of'' which it is sometimes considered a synonym, or a hybrid of ''S. etonia and S. palmetto.'' Conservation Only one population is known; it consists of a few individuals in Crandon Park, Miami, Florida. It is seriously threatened and may possibly already be extinct in the wild, although it is still in cultivation as an ornamental. It has been collected in nature only from rocky pinelands in the region, areas which are now rapidly becoming urbanized. Dr.Larry Noblick and Daniel Tucker from the Montgomery Botanical Center have found two populations in the Miami area. Seeds were collected and all 45 germinated.

Sabal Bermudana
''Sabal bermudana'', commonly known as the Bermuda palmetto or bibby-tree, is one of 15 species of palm trees in the genus ''Sabal'' and is endemic to Bermuda although reportedly naturalized in the Leeward Islands. It was greatly affected by the introduction of non-native plants such as the Chinese fan palm, which created competition for space that it usually lost. Description ''Sabal bermudana'' grows up to in height, with the occasional old tree growing up to in height, with a trunk up to in diameter. It is a fan palm (Arecaceae tribe Corypheae), with the leaves with a bare petiole terminating in a rounded fan of numerous leaflets. Each leaf is long, with 45-60 leaflets up to long.

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Evolutionary
Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book '' On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) traits vary among individuals ...
