WIND DISPERSAL

Western salsify or goatsbeard showing dense, puff-like cluster of numerous parachute seeds. Each achene has an umbrella-like crown of plumose hairs and may literally be carried into the atmosphere by strong ascending air currents.

WATER DISPERSAL Although seeds of plants that grow in

water are obviously spread by water, there are many other ways in which water plays a part in dispersing seeds.

• Seeds of some tropical trees can even be carried along by ocean currents to land on shores half a world away.

ANIMAL DISPERSAL Animals of all

sorts and sizes help plants to disperse their seeds. The method they use depends on the type of seed.

EXPLOSION DISPERSAL - SPLITTING Some plants

provide their fruits (seedpods) with a mechanism that ejects the seeds from the pod by force.

HELICONIA Heliconia, derived from the Greek

word helikonios, is a genus of about 100 to 200 species of flowering plants native to the tropical Americas and the Pacific Ocean islands west to the Indonesia.

These herbaceous plants range from 0.5 to nearly 4.5 meters tall depending on the species simple leaves of these plants are 15–300 cm.

ORCHID

The Orchidaceae or orchid family is a diverse and widespread family of flowering plants with colorful and fragrant blooms.

The family also includes Vanilla, and many commonly cultivated plants such as Phalaenopsis and Cattleya.

GINGER Ginger or ginger root is

the rhizome of the plant zingiber officinale, consumed as a Delicacy, medicine, or spice. It lends its name to its genus and family.

Ginger cultivation began in South Asia and has since spread to East Africa and the Caribbean.

DILLENIACEAE Dilleniaceae is the botanical

name, for a family of flowering plants. Such a family has been universally recognized by taxonomists. It is known to gardeners for the genus Hibbertia, which contains many commercially valuable garden species.
