Ceratolobus
''Ceratolobus'' was a dioecious genus of flowering plants in the palm family found in Southeast Asia, commonly called rotan. Its species are now included within the genus ''Calamus''. They are only differentiated from close relatives like '' Korthalsia'', ''Calamus'', and ''Daemonorops'' by leaf sheath appendages or inflorescence variations.Uhl, Natalie W. and Dransfield, John (1987) ''Genera Palmarum - A classification of palms based on the work of Harold E. Moore''. Lawrence, Kansas: Allen Press. / The Greek genus name combines "horn" and "capsule".Riffle, Robert L. and Craft, Paul (2003) ''An Encyclopedia of Cultivated Palms''. Portland: Timber Press. / Description Among rattans they are relatively delicate and vinelike, very spiny and densely clustering, stems eventually becoming bare and covered in leaf scars. The leaves, rachises, and petioles (when present) may be equipped with simple climbing adaptations like barbs, cirrus, and grapnel spines but the climbing habit ...

Rattan
Rattan, also spelled ratan, is the name for roughly 600 species of Old World climbing palms belonging to subfamily Calamoideae. The greatest diversity of rattan palm species and genera are in the closed- canopy old-growth tropical forests of Southeast Asia, though they can also be found in other parts of tropical Asia and Africa. Most rattan palms are ecologically considered lianas due to their climbing habits, unlike other palm species. A few species also have tree-like or shrub-like habits. Around 20% of rattan palm species are economically important and are traditionally used in Southeast Asia in producing wickerwork furniture, baskets, canes, woven mats, cordage, and other handicrafts. Rattan canes are one of the world's most valuable non-timber forest products. Some species of rattan also have edible scaly fruit and heart of palm. Despite increasing attempts in the last 30 years at commercial cultivation, almost all rattan products still come from wild-harvested ...

Calamus (palm)
''Calamus'' is a genus of flowering plants in the palm family Arecaceae that are among several genera known as rattan palms. There are an estimated 400 species in this genus, all native to tropical and subtropical Asia, Africa, and Australia. Description They are dioecious, mostly leaf-climbing lianas with slender, reedy stems. To aid scrambling some species have evolved hooks on the underside of the midrib, or more commonly by modified "pinnae" or tendrils in the form of stout, backward-pointing spines. These stems may grow to lengths of 200 metres. The fruits of certain species, in particular '' Calamus draco'', produce a red resin known as "Dragon's blood". Species , ''Plants of the World Online'' recognises 415 species: # ''Calamus acamptostachys'' (Becc.) W.J.Baker # ''Calamus acanthochlamys'' J.Dransf. # ''Calamus acanthophyllus'' Becc. # '' Calamus acanthospathus'' Griff. # ''Calamus acaulis'' A.J.Hend., N.K.Ban & N.Q.Dung # '' Calamus adspersus'' Blume # ''C ...

Calamoideae
Calamoideae is a subfamily of flowering plant in the palm family found throughout Central America, South America, Africa, India, China, Southeast Asia and Australia. It is represented by 21 genera - containing nearly a quarter of all species in the palm family - including the largest genus, ''Calamus'', the type genus of the group. Only four are found in the New World while the rest are Old World denizens, usually found in equatorial swampland or along tropical coastlines. While the many species show marked differences, the bracts of all orders are tubular, the flowers are almost always borne in dyads or dyad derivatives, but most marked as an identifier among these palms are the overlapping scales covering the fruit; occasionally small and irregular they are, in most cases, neatly aligned in vertical rows. Also common to the group are varying forms of armament: spines along leaf margins or on sheaths, root and stem spines, reflexed rachis cirri, or specialized hooks among t ...

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 meaning t ...

Rain Forest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...
