Hedyscepe
''Hedyscepe canterburyana'', the big mountain palm or umbrella palm, is the sole species in the genus ''Hedyscepe'' of the family Arecaceae. It is endemic to Lord Howe Island, Australia and is threatened by habitat loss. It is a solitary palm with a distinct crownshaft, and bears unisexual flowers of both sexes. With the ''Rhopalostylis'' palms of Norfolk Island and New Zealand it forms the botanic subtribe Rhopalostylidinae. If differs from ''Rhopalostylis'' in minor floral details including having more than six stamens, and in being protandrous rather than protogynous. The two genera were formerly included in Archontophoenicinae until a recent revision (Dransfield, Uhl et al., 2005). In some (but not all) molecular phylogenetic analyses, ''Hedyscepe'' was found to be nested in the New Caledonia endemic ''Basselinia''. Description ''Hedyscepe canterburyana'' is a slow-growing palm up to tall which grows on mountain forests, cliffs, and exposed ridges overlooking the sea, at abou ...

Rhopalostylidinae
Rhopalostylidinae is a botanical subtribe consisting of two genera of palms from Australia and New Zealand, ''Hedyscepe'' and ''Rhopalostylis''. These two genera were formerly included in Archontophoenicinae, to which they are morphologically similar (Dowe 2010:233), until a recent revision (Dransfield, Uhl et al., 2005). Description The palms in this subtribe are medium-sized palms, with well-developed, distinct crownshafts and strictly pinnate Pinnation (also called pennation) is the arrangement of feather-like or multi-divided features arising from both sides of a common axis. Pinnation occurs in biological morphology, in crystals, such as some forms of ice or metal crystals, and in ... leaves with generally short and massive petioles. The inflorescences are branched to two or three orders, with the prophyll and penduncular bracts similar (Uhl and Dransfield 1987:367).

Lord Howe Island
Lord Howe Island (; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, part of the Australian state of New South Wales. It lies directly east of mainland Port Macquarie, northeast of Sydney, and about southwest of Norfolk Island. It is about long and between wide with an area of , though just of that comprise the low-lying developed part of the island. Along the west coast is a sandy semi-enclosed sheltered coral reef lagoon. Most of the population lives in the north, while the south is dominated by forested hills rising to the highest point on the island, Mount Gower (). The Lord Howe Island Group comprises 28 islands, islets, and rocks. Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about to the southeast of Howe. To the north lies a cluster of seven small uninhabited islands called the Admiralty Group. The first repo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhopalostylis
''Rhopalostylis'' is a genus of two species of palms native to the South Pacific. Both are smooth-trunked, with regular ringed scars from fallen leaves. The leaves are 3–5 m in length, and the leaf bases encircle the trunk. Distribution ''Rhopalostylis baueri'' occurs on Norfolk Island and the Kermadec Islands northeast of New Zealand; the Kermadec Islands population, formerly separated as ''R. cheesemanii'', was included in '' R. baueri'' in 2005 after comparison revealed no significant differences. '' R. sapida'', known as the nikau palm, is the only palm native to mainland New Zealand, and is found in lowland forests in the North Island, in coastal areas of the South Island as far south as Banks Peninsula, and on the Chatham Islands at 44°S. ''R. sapida'' thus has the southernmost range of any palm genus. Classification Subfamily: Arecoideae; tribe: Areceae; subtribe: Rhopalostylidinae. ''Rhopalostylis'' is closely related to the Lord Howe Island genus ''Hedyscepe ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archontophoenicinae
Archontophoenicinae is a botanical subtribe consisting of four genera of palms, namely ''Archontophoenix'' from Queensland and New South Wales and '' Actinokentia'', '' Chambeyronia'' and ''Kentiopsis'' from New Caledonia. Phylogenetic relationships between the four genera are unresolved.Domenech, B., C. B. Asmussen-Lange, W. J. Baker, E. Alapetite, J. C. Pintaud, and S. Nadot.

Carl Georg Oscar Drude
Carl Georg Oscar Drude (5 June 1852 in Braunschweig – 1 February 1933 in Dresden) was a German botanist. From 1870 he studied science and chemistry at the Collegium Carolinum in Braunschweig, relocating to the University of Göttingen the following year, where he was influenced by August Grisebach (1814-1879). In 1873 he obtained his PhD and subsequently served as an assistant to Friedrich Gottlieb Bartling (1798-1875). From 1876 to 1879 he worked as a lecturer in botany at Göttingen, followed by an appointment as chair of botany at Dresden Technical University (1879). Here he served as director of its botanical gardens, which he systematically configured according to a phytogeographical principle. He remained at Dresden until his retirement in 1920, twice serving as university rector (1906-1907, 1918-1919). He is known best for his research in the field of plant geography, that included mapping of the world's different floristic zones. With Adolf Engler Heinrich Gus ...

Howea Belmoreana
''Howea belmoreana'', the curly palm, kentia palm, or Belmore sentry palm, is a species of flowering plant in the family (biology), family Arecaceae, endemic species, endemic to Lord Howe Island, Australia. It and ''Howea forsteriana'' probably evolved from a common ancestor through sympatric speciation. The canopy of a mature kentia palm tree spreads in diameter and contains roughly 36 leaves. ''Howea belmoreana'' has gained the Royal Horticultural Society's Award of Garden Merit. Effects of mycorrhiza on speciation ''Howea belmoreana'' is restricted to the volcanic soils on Lord Howe Island, whereas ''H. forsteriana'' is found on both alkaline calcareous and volcanic soils, the two most common soil types found on the island. ''Howea belmoreana'' is more common on volcanic soils and has a higher survival rate than ''H. forsteriana''. Osborne et al. (2018) suggest that the speciation of ''H. forsteriana'' and ''Howea belmoreana'' is partially a result of difference in arbuscu ...

Monotypic Arecaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

Endemic Flora Of Lord Howe Island
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates. The term "seed" also has a general me ...
