Zombia
''Zombia antillarum'', commonly known as the zombie palm, is a species of palm tree and the only member of the genus ''Zombia''. It is endemic to the island of Hispaniola (both the Dominican Republic and Haiti) in the Greater Antilles. Usually found in dry, hilly areas of northern and southern Haiti and the northwest of the Dominican Republic, ''Z. antillarum'' is a relatively short fan palm with clustered stems and a very distinctive appearance caused by its persistent spiny leaf sheaths. Threatened by habitat destruction in Haiti, ''Z. antillarum'' is a popular ornamental species due to its distinctive appearance, low maintenance requirements and salt tolerance. Description ''Zombia antillarum'' is a small palm which grows in dense, multi-stemmed clumps with stems up to tall and in diameter. Individuals bear nine to 12 fan-shaped (or palmate) leaves which are greyish-white on the lower surface. The leaf sheaths remain attached to the stem after the leaf drops o ...

Coccothrinax
''Coccothrinax'' is a genus of palms in the family Arecaceae. There are more than 50 species described in the genus, plus many synonyms and subspecies. A new species (''Coccothrinax spirituana'') was described as recently as 2017. Many ''Coccothrinax'' produce thatch. In Spanish-speaking countries, ''guano'' is a common name applied to ''Coccothrinax'' palms. The species are native throughout the Caribbean, the Bahamas, extreme southern Florida and southeastern Mexico, but most of the species are known only from Cuba. Description ''Coccothrinax'' is a genus of small to medium-sized, fan palms with relatively slender stems and 8 to 22 palmate leaves. The stems are initially covered by fibrous leaf sheaths. These break down into a network of fibres or spines, eventually leaving a bare trunk covered with leaf scars. The undersides of the leaflets are often silvery-grey; this is reflected in the common name "silver palm", which is given to many species of ''Coccothrinax''. The b ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Genera Palmarum
''Genera Palmarum'' is a botany reference book that gives a detailed overview of the systematic biology of the palm family (Arecaceae). The first edition of ''Genera Palmarum'' was published in 1987. The second edition was published in 2008, with a reprint published in 2014. ''Genera Palmarum'' is currently the most detailed monograph on palm taxonomy and systematics. History Beginnings When Liberty Hyde Bailey, an American horticulturist and botanist who founded the L. H. Bailey Hortorium at Cornell University, began studying palms in the early 1900s, about 700 species had been identified. The number reached 1,000 by 1946, the rise due in large part to his intensive study of the family. Ill health finally forced Bailey to discontinue collecting abroad in 1949, at the age of 91. He continued to study, compare, and write about his palm specimens. His ultimate goal was to produce an authoritative guide to all palms, titled ''Genera Palmarum''. Harold E. Moore, Jr. (1917–1980), a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chamaerops
''Chamaerops'' is a genus of flowering plants in the family Arecaceae. The only currently fully accepted species is ''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 fully accepted ''Chamaerops humilis,'' there are a few taxa of unresolved status plus numerous species synonymised under ''Chamaerops humilis''. The species ''Chamaerops humilis'' itself has three accepted varieties as follows: *''Chamaerops humilis'' var. ''argentea'' André (syn. ''C. h.'' var. ''cerifera'') – "Atlas mountain palm" of Northwest Africa. Leaves glaucous. *''Chamaerops humilis'' var. ''epondraes'' – Northwest Africa. Leaves glaucous. *''Chamaerops humilis'' var. ''humilis'' – Southwest Europe. Leaves green. There also are at least three cultivars (''C. humilis'' var. ''humilis'' 'Nana', ''C. humilis'' 'Vulcano', ''C. humilis'' 'Stella'). ...

Anemophily
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges, and rushes. Other common anemophilous plants are oaks, pecans, pistachios, sweet chestnuts, alders and members of the family Juglandaceae (hickory or walnut family). Approximately 12% of plants across the globe are pollinated by anemophily, including cereal crops like rice and corn and other prominent crop plants like wheat, rye, barley, and oats. In addition, many pines, spruces, and firs are wind-pollinated, and. Syndrome Features of the wind-pollination syndrome include a lack of scent production, a lack of showy floral parts (resulting in small, inconspicuous flowers), reduced production of nectar, and the production of enormous numbers of pollen grains. This distinguishes them from entomophilous and zoophilous species (whose pollen is spread by insects and vertebrates re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carpel
Gynoecium (; ) is most commonly used as a collective term for the parts of a flower that produce ovules and ultimately develop into the fruit and seeds. The gynoecium is the innermost whorl of a flower; it consists of (one or more) ''pistils'' and is typically surrounded by the pollen-producing reproductive organs, the stamens, collectively called the androecium. The gynoecium is often referred to as the "female" portion of the flower, although rather than directly producing female gametes (i.e. egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces egg cells. The term gynoecium is also used by botanists to refer to a cluster of archegonia and any associated modified leaves or stems present on a gametophyte shoot in mosses, liverworts, and hornworts. The corresponding terms for the male parts of those plants are clusters of antheridia within the androecium. Flowers that bear a gynoecium but no stamens are called ...

Stamen
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''sporangium, microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in ''Canna (plant), Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea'' ...

Plant Sexuality
Plant reproductive morphology is the study of the physical form and structure (the Plant morphology, morphology) of those parts of plants directly or indirectly concerned with sexual reproduction. Among all living organisms, flowers, which are the reproductive structures of flowering plant, angiosperms, are the most varied physically and show a correspondingly great diversity in methods of reproduction. Plants that are not flowering plants (green algae, mosses, Marchantiophyta, liverworts, hornworts, ferns and gymnosperms such as conifers) also have complex interplays between morphological adaptation and environmental factors in their sexual reproduction. The breeding system, or how the sperm from one plant fertilizes the ovum of another, depends on the reproductive morphology, and is the single most important determinant of the genetic structure of nonclonal plant populations. Christian Konrad Sprengel (1793) studied the reproduction of flowering plants and for the first time it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...
