Strangler fig is the common name for a number of tropical and subtropical plant species, including some banyans and unrelated vines, including among many other species: * ''Ficus aurea'', also known as the Florida strangler fig * ''Ficus barbata'', also known as the bearded fig * ''Ficus benghalensis'' * ''Ficus burtt-davyi'' * ''Ficus citrifolia'' * ''Ficus craterostoma'' * ''Ficus tinctoria'' * ''Ficus macrophylla'' * ''Ficus obliqua'' * ''Ficus virens'' * ''Ficus watkinsiana'' They all share a common "strangling" growth habit that is found in many tropical forest species, particularly of the genus ''Ficus''.〔Zhekun, Zhou & Michael G. Gilbert (2003) Flora of China (Moraceae) 5: 21-73. (hua.huh.harvard.edu )〕 This growth habit is an adaptation for growing in dark forests where the competition for light is intense. These plants begin life as hemiepiphytes, when their seeds, often bird-dispersed, germinate in crevices atop other trees. These seedlings grow their roots downward and envelop the host tree while also growing upward to reach into the sunlight zone above the canopy.〔Serventy, V. 1984. Australian Native Plants. Victoria: Reed Books.〕〔Light in the rainforest 1992 Tropical topics. Vol 1 No. 5, (epa.qld.gov.au )〕 An original support tree can sometimes die, so that the strangler fig becomes a "columnar tree" with a hollow central core. ==Gallery== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「strangler fig」の詳細全文を読む スポンサード リンク
