         and water affect the various floras in Indonesia. Indonesia has tropical climate,
         with different humidity, temperature, and wind direction as well as
         precipitation level. In consequence, there are different types or floras.
         Typeof flora in Indonesia is classified based on geological factor, climatic
         factor, and elevation factor.
         a. Type of Flora based on the Geological factors
Based on geological factors, flora in Indonesia is classified into
threeregions, namely flora in sunda shelf, flora in sahulshelf, and flora in
trasitional zone.
 Flora in sunda shelf
    Flora in Sunda shelf is classified into asiatic flora. Example : types of
    timber, rattan and jackfruit trees. Thre are various ebdemic tree,
    located in a very specialized and localizedarea. Example : raflesia

    leeve, while in swamp area there is sago for food production.
    Endemic flora, such as rhododendron sp is flourishing in upper area.
 Flora in Trasitional Zone
    Vegetation in the transisional zone is characterized by vegetation of
    tropical savannah, example: Nusa tenggara island, forest area in
    Celebes island, and forest in Moluccas (it contains various type of
    trees).

    area is similar to vegetation in borneo island. Coastal vegetation and
    low land vgetation are similar to vegetation in papua island.
