Desmoncus
''Desmoncus'' is a genus of mostly climbing, spiny palms native to the Neotropics. The genus extends from Mexico in the north to Brazil and Bolivia in the south, with two species present in the southeastern Caribbean (Trinidad and the Windward Islands).Govaerts, R. & Dransfield, J. (2005). World Checklist of Palms: 1–223. The Board of Trustees of the Royal Botanic Gardens, Kew. Description ''Desmoncus'' is best known as a genus of climbing palms. Twenty-three of the 24 species recognised by Andrew Henderson in his revision of the genus are climbers; only one, '' D. stans'' is free-standing. Almost all Neotropical climbing palms belong to ''Desmoncus''—the one exception being '' Chamaedorea elatior''. ''Desmoncus'' leaves are pinnately compound and are made up of a leaf sheath, petioles, rachis, and individual leaflets. The ends of the leaves are modified into a climbing structure called a cirrus. Instead of leaflets, the cirrus usually has grappling hook-like stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bactris
''Bactris'' is a genus of spiny palms which are native to Mexico, South and Central America and the Caribbean. Most species are small trees about tall, but some are large trees while others are shrubs with subterranean stems. They have simple or pinnately compound leaves and yellow, orange, red or purple-black fruit. The genus is most closely related to several other spiny palms—''Acrocomia'', ''Aiphanes'', ''Astrocaryum'' and ''Desmoncus''. The fruit of several species is edible, most notably '' B. gasipaes'', while others are used medicinally or for construction. The ancestors of the genus are believed to have entered South America during the late Cretaceous. ''Bactris'' shows high rates of speciation. Description Both stems and leaves of ''Bactris'' species are generally covered with spines. Stems generally bear spines on the internodes; in '' B. glaucescens'' and '' B. setulosa'' spines are also present on the nodes. A few species lack spines on their stems. All species ...

Aiphanes
''Aiphanes'' is a genus of spiny palms which is native to tropical regions of South and Central America and the Caribbean.Kew World Checklist of Selected Plant Families There are about 26 species in the genus (see below), ranging in size from understorey shrubs with subterranean stems to subcanopy trees as tall as . Most have pinnately compound leaves (leaves which are divided into leaflets arranged feather-like, in pairs along a central axis); one species has entire leaves. Stems, leaves and sometimes even the fruit are covered with spines. Plants flower repeatedly over the course of their lifespan and have separate male and female flowers, although these are borne together on the same inflorescence. Although records of pollinators are limited, most species appear to be pollinated by insects. The fruit are eaten by several birds and mammals, including at least two species of amazon parrots. Carl Ludwig Willdenow coined the name ''Aiphanes'' in 1801. Before that, species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leaf Sheath
A leaf ( : leaves) is any of the principal appendages of a vascular plant stem, usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf but in some species, including the mature foliage of ''Eucalyptus'', palisade mesophyll is present on both sides and the leaves are said to be isobilateral. Most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata (pores that intake and output gases), the amount and structure of epicuticular wax and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll that is essential for photosynthesis as it absorbs light en ...

Aiphanes Horrida
''Aiphanes horrida'' is a Arecaceae, palm native to northern South America and Trinidad and Tobago. ''Aiphanes horrida'' is a solitary, spine (botany), spiny tree. In the wild it grows 3–10 metres tall (9–30 feet) tall with a stem diameter of 6–10 centimetres (2–4 inches); cultivated trees may be as much as 15 m (49') tall with a 15 cm (6") diameter. The pericarp, epicarp and mesocarp of the fruit are rich in carotene and are eaten in Colombia, while the seeds are used to make candles. In parts of the Colombian Llanos endocarps are used to play games. The range of the species is found in Tropical and subtropical dry broadleaf forests, dry forests between sea level and 1700 m (5600') above sea level in Bolivia, Brazil, Colombia, Peru, Trinidad and Tobago and Venezuela, but is not native to Ecuador. The species is cultivated as an ornamental throughout the tropics. Many authors, including Henderson ''et al.'' (1995) and Borchenius and Bernal (1996) use ''A. aculea ...

Astrocaryum
''Astrocaryum'' is a genus of about 36 to 40 species of palms native to Central and South America and Trinidad. Description ''Astrocaryum'' is a genus of spiny palms with pinnately compound leaves–rows of leaflets emerge on either side of the axis of the leaf in a feather-like or fern-like pattern. Some species are single-stemmed, while others grow in multi-stemmed (caespitose) clumps. They are pleonanthic—they flower repeatedly over the course of their lifespan—and monoecious, meaning that there are separate male and female flowers, but individuals plants bear both types of flowers. Taxonomy History The type species, ''Astrocaryum aculeatum'', was first described by German botanist Georg Friedrich Wilhelm Meyer in 1818 based on a specimen from the Essequibo River in Guyana. Species One well known member of the genus is ''Astrocaryum vulgare'', typical in the Pará state of Brazil. '' Astrocaryum mexicanum'', a common palm of the Caribbean coast of Central America ...

Acrocomia
''Acrocomia'' is a genus of Arecaceae, palms which is native to the Neotropics, ranging from Mexico in the north, through Central America and the Caribbean, and through South America south to Argentina. Description ''Acrocomia'' is a genus of Spine (botany), spiny, pinnate-leaved palms which range from large trees to small palms with short, subterranean stems. The species bears branched inflorescences which are located among the leaves. The Plant sexuality#Individual reproductive unit (a flower in angiosperms), unisexual flowers; female flowers are born near the base of the inflorescence, while male flowers are borne towards the tips. Fruit are large, single-seeded, and vary in colour from yellow, to orange, to brown. Ricardo Vargas‑Carpintero et al. have concluded that "main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogeny
A phylogenetic tree (also phylogeny or evolutionary tree Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA.) is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. All life on Earth is part of a single phylogenetic tree, indicating common ancestry. In a ''rooted'' phylogenetic tree, each node with descendants represents the inferred most recent common ancestor of those descendants, and the edge lengths in some trees may be interpreted as time estimates. Each node is called a taxonomic unit. Internal nodes are generally called hypothetical taxonomic units, as they cannot be directly observed. Trees are useful in fields of biology such as bioinformatics, systematics, and phylogenetics. ''Unrooted'' trees illustrate only the relatedness of the leaf nodes and do not require the ancestral root to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastid
The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids) is a membrane-bound organelle found in the Cell (biology), cells of plants, algae, and some other eukaryotic organisms. They are considered to be intracellular endosymbiotic cyanobacteria. Examples include chloroplasts (used for photosynthesis), chromoplasts (used for pigment synthesis and storage), and leucoplasts (non-pigmented plastids that can sometimes differentiate). The event which led to permanent endosymbiosis in the Archaeplastida clade (of Embryophyte, land plants, red algae, and green algae) probably occurred with a cyanobiont (a symbiotic cyanobacteria) related to the genus ''Gloeomargarita lithophora, Gloeomargarita'', around 1.5 billion years ago. A later primary endosymbiosis event occurred in photosynthetic ''Paulinella'' amoeboids about 90–140 million years ago. This plastid belongs to the "PS-clade" (of the cyanobacteria genera ''Prochlorococcus'' and ''Synechococcus''). Chloroplas ...
