<P> The fruit, a nut, is of a brownish colour and can measure up to 12 inches (300 mm) in length and 2.5 inches (64 mm) in diameter . Seeds grow within until such time as the nut bursts, sending the seeds forth and propagating . The nut is edible and often eaten raw or roasted, with a flavor similar to a European chestnut; it may also be ground and made as a hot drink . The fruit is not eaten . </P> <P> The genus name is derived from a language spoken in Guyana . The species name is Latin for "aquatic". It is classified in the subfamily Bombacoideae of the family Malvaceae . Previously it was assigned to Bombacaceae . </P> <P> The name "money tree" seems to refer to a story of its origin, where a poor man prayed for money, found this "odd" plant, took it home as an omen, and made money selling plants grown from its seeds . </P> <P> In East Asia, Pachira aquatica (Chinese: 馬 拉巴 栗; pinyin: Mǎlābā lì; literally: "Malabar chestnut") is often referred to as the "money tree" (發財 樹 fācái shù). The tree had long been popular as an ornamental in Japan . In 1986, a Taiwanese truck driver first cultivated five small trees in a single flowerpot with their trunks braided . The popularity of these ornamentals took off in Japan and later much of the rest of East Asia . They are symbolically associated with good financial fortune and are typically seen in businesses, sometimes with red ribbons or other auspicious ornamentation attached . The trees play an important role in Taiwan's agricultural export economy with exports of NT $250 million (US $7 million) in 2005 . However, much of what is in cultivation sold as Pachira aquatica is, in actuality, a similar species, P. glabra, which develops a thick base at a younger age and has a smaller growth habit, less showy flowers, and a 6" green seed pod rather than 12" brown seed pod . </P>
