Myristica fragrans was introduced to Singapore by Sir Thomas Stamford Raffles in 1802, and were planted at the foot of Government Hill (now Fort Canning Hill) to experiment its cultivation for spice trade (Wheatley, 1954). A craze for nutmeg soon started, and by 1848, there were about 56,000 trees in 24 plantations covering an area of 480 ha (Ridley, 1897; Wikkramatileke, 1965). However, in 1859, a disease from a beetle spread from Malaysia to Singapore and wiped out most of the trees (Burkill, 1966). Presently, Nutmeg trees can only be found sparingly in several parks, including the Singapore Botanic Gardens.
The fleshly fruit wall of the is the commercial nutmeg sold as a sweetmeat (Rao, 1989). The red aril which envelops the seed is known as the mace and the black seed, also known as the nutmeg are both used as a spice.
The small, pale yellow, and globular flowers are unisexual. A study of the floral biology of Myristica fragrans in India found that it is visited by a species of beetle, Formicomus braminus (Armstrong & Drummond, 1986). Pollination occurs when the beetles collected the pollen from the male flower and mistakenly enter a female one thinking that it is a male one, thus unwittingly depositing the pollen.
