Its range extends from Mexico south to Peru and Brazil, but it has been widely introduced to South and Southeast Asia, as well as the Pacific Islands, including Hawaii. Common names include saman, rain tree and monkeypod (see also below). It is often placed in the genus ''Samanea'', which by yet other authors is subsumed in ''Albizia'' entirely. ==Description== Saman is a wide-canopied tree with a large symmetrical crown. It usually reaches a height of and a diameter of 40 m. The leaves fold in rainy weather and in the evening, hence the name "rain tree" and "five o'clock tree" (Pukul Lima) in Malay. Several lineages of this tree are available, e.g., with reddish pink and creamish golden colored flowers. During his 1799–1804 travels in the Americas, Alexander von Humboldt encountered a giant saman tree near Maracay, Venezuela. He measured the circumference of the parasol-shaped crown at 576 ft (about 180.8 m〔Presuming von Humboldt used the Magdeburg foot of 1755, introduced in Prussia in 1793, which was 1.044 ft (31.385 cm).〕), its diameter was around 190 ft (about 59.6 m), on a trunk at 9 ft (about 2.8 m) in diameter and reaching just 60 ft (nearly 19 m) in height. Humboldt mentioned the tree was reported to have changed little since the Spanish colonization of Venezuela; he estimated it to be as old as the famous Canary Islands dragon tree (''Dracaena draco'') of Icod de los Vinos on Tenerife.〔von Humboldt & Bonpland (1820): pp.98-100〕 The tree, called ''Samán de Güere'' (transcribed ''Zamang del Guayre'' by von Humboldt) still stands today, and is a Venezuelan national treasure. Just like the dragon tree on Tenerife, the age of the saman in Venezuela is rather indeterminate. As von Humboldt's report makes clear, according to local tradition, it would be older than 500 years today, which is rather outstanding by the genus' standards. It is certain, however, the tree is quite more than 200 years old today, but it is one exceptional individual; even the well-learned von Humboldt could not believe it was actually the same species as the saman trees he knew from the greenhouses at Schönbrunn Castle.〔von Humboldt & Bonpland (1820): p.99 footnote〕 Large branches of the tree tend to break off, particularly during rainstorms. This can be hazardous as the tree is very commonly used for avenue plantation. 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「Albizia saman」の詳細全文を読む スポンサード リンク
