Description
Bearing fruit

Myristica fragrans is an evergreen tree, usually 5–15 m (16–49 ft) tall, but occasionally reaching 20 m (66 ft) or even 30 m (98 ft) on Tidore. The alternately arranged leaves are dark green, 5–15 cm (2.0–5.9 in) long by 2–7 cm (0.8–2.8 in) wide with petioles about 1 cm (0.4 in) long. The species is dioecious, i.e. "male" or staminate flowers and "female" or carpellate flowers are borne on different plants, although occasional individuals produce both kinds of flower. The flowers are bell-shaped, pale yellow and somewhat waxy and fleshy. Staminate flowers are arranged in groups of one to ten, each 5–7 mm (0.2–0.3 in) long; carpellate flowers are in smaller groups, one to three, and somewhat longer, up to 10 mm (0.4 in) long.[4]

Carpellate trees produce smooth yellow ovoid or pear-shaped fruits, 6–9 cm (2.4–3.5 in) long with a diameter of 3.5–5 cm (1.4–2.0 in). The fruit has a fleshy husk. When ripe the husk splits into two halves along a ridge running the length of the fruit. Inside is a purple-brown shiny seed, 2–3 cm (0.8–1.2 in) long by about 2 cm (0.8 in) across, with a red or crimson covering (an aril). The seed is the source of nutmeg, the aril the source of mace.[2][4]

Taxonomy

Myristica fragrans was given a binomial name by the Dutch botanist Maartyn Houttuyn in 1774. It had earlier been described by Georg Eberhard Rumphius, among others.[5] The specific epithet fragrans means "fragrant".[6]
