tica moschata_, _M. officinalis_, or _aromatica_.--This tree is
of a larger growth than the clove, attaining a height of thirty feet,
and has its leaves broader in proportion to their length; the upper
surface of these is of a bright green, the under of a greyish color.
It is a dioecious plant, having male or barren pale yellow flowers upon
one tree, and female or fertile flowers upon another. The fruit is
drupaceous, and opens by two valves when ripe, displaying the
beautiful reticulated scarlet arillus, which constitutes mace. Within
this is a hard, dark brown, and glossy shell, covering the kernel,
which is the nutmeg of the shops.
The kernels of _M. tomentosa_ are also used as aromatics, under the
name of wild or male nutmegs.
Lindley describes two other species, _M. fatua_, a native of Surinam,
with greenish white flowers, and _M. sebifera_ or _Virola sebifera_, a
native of Guiana, with yellowish green flowers.
By expression, nutmegs are made to yield a concrete oil, called
_Adeps Myristicae_, or sometimes erroneously oil of mace. A volatile
oil is also procured by distillation. Nutmegs and mace are used
medicinally as aromatic stimulants and condiments. In large doses they
have a narcotic effect. The fleshy part of the fruit is used as a
preserve.
Dr. Oxley has given such an admirable account of the nutmeg and its
cultivation, as the result of 20 years experience in Singapore, that I
shall draw largely from his valuable paper, which is contained in the
second volume of "The Journal of the Indian Archipelago," page 641.
The nutmeg tree, like many of its class, has a strong tendency to
become monoecious, and planters in general are well pleased at this
habit, thinking they secure a double advantage by having the male and
female flowers on the same plant. This is, however, delusive, and
being against the order of nature, the produce of such trees is
invariably inferior, showing itself in the production of double nuts
and other deformities. It is best, therefore, to have only female
trees, with a due proportion of males.
The female flowers, which are merely composed of a tripid calyx and no
corolla, when produced by a tree in full vigor are perfectly
urceolate, slightly tinged with green at the base, and well filled by
the ovary, whereas the female flowers of weakly trees are entirely
yellow, imperfectly urceolate, and approach more to the staminiferous
flowers of the male.
