2. 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.

3. 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.

4. ANIMAL DISPERSAL  Animals of all sorts and sizes help plants to disperse their seeds. The method they use depends on the type of seed.

5. EXPLOSION DISPERSAL - SPLITTING  Some plants provide their fruits (seedpods) with a mechanism that ejects the seeds from the pod by force.

6. 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.

7. 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.

8. 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.

9. 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.
