Known commonly as the Banana, the genus
Musa contains about 25 species of giant treelike herbs
from Asia. Unlike other trees, the banana never grows a woody
secondary layer. Once the banana plant produces flowers and fruit,
that leaf stalk will die and new stalks will rise from the roots.
Bananas are very nutritious containing
vitamins A, B, C and E. The banana relative Plantians are cooked
and eaten like vegetables in tropical America and Africa. One
species of Musa, Manila Hemp, is grown for fiber and used
in rope making and paper pulp. |

Coffea arabica
with beans |
There are about 40 species of Coffea
shrubs or trees, native to Old World tropics. This plant is widely
grown in tropical areas around the world for the coffee beans
used in commercial coffee production. The British were heavy
coffee consumers until disease killed off many plantations, forcing
them to switch to tea. After the crisis many never switched back.
The part of the plant used for making coffee
is the seeds within the fruit. The beans are harvested and then
roasted differently, according to the type of coffee desired. The
temperature at which the beans are roasted has a direct effect
on the flavor of the coffee. |

Several kinds of citrus fruits are commercially
important, such as the orange, mandarin, lemon, lime, and grapefruit.
Among subtropical fruits, those belonging to the citrus groups
are most important. The fruits of the American Wonder Lemon,
Citrus limon 'Ponderosa', can grow to an amazing diameter
of 4.5 inches. Citrus fruits are known to be an excellent
source of vitamin C and they are a commercial source of citric
acid. The leaves of citrus relative Murraya are mixed
with tumeric to make curry. |

Though not typically thought of as a fruit,
the Vanilla plant yields pods used in the production of
commercial vanilla. A member of the orchid family, there are
approximately 90 species of Vanilla but only a few are
the source of commercial vanilla. The vanilla orchid is grown
in many tropical areas, where temperature and humidity are high,
the soil is rich in organic matter, and there is constant shade.
The vines are usually supported on poles or the trunks of shade
trees. The flowers must be hand pollinated when the plant is
grown in areas where its natural pollinating insects are not
found.
The fully grown but unripe seed pods are
dried and fermented. The fermented pods become covered with a
frosty coating of crystals which contain vanillin. Vanilla extract
is made from beans which have been soaked in alcohol. Vanilla
is well known for its uses in ice cream, chocolates, candies,
desserts and liquers. |
