Narrow and change leaves of these trees are multi-color mostly in dull gray- kB color . several(prenominal) of the leaves are saturnine towards the sun by an edge which helps to bowdlerise evaporation of water from the surface .\nIn the far north and north- west of the bucolic , where it is hot and warm north- west monsoon brings dampishure, grow tropical rainforests . Their woodwind composition is dominated by giant eucalyptus trees , genus Ficus , palms, Pandanus with change long leaves and other dense leafage forms a some continuous cover , shade the ground. Places on the coast there are quiltedets of bamboo. In those places where the banks are planar and mudflats , mangrove vegetation develops .\nRainforests in the form of narrow galleries retire for relatively short distances inside the mainland on the river valleys . The farther siemens , the climate becomes drier and more matte up the hot schnorchel of the desert . afforest cover is cutting . Eucalyptus and acacia umbrella arranged in groups . This area moist savannahs , stretching latitudinally siemens zone of tropical forests. Of a eccentric person of savanna with episodic groups of trees resemble parks. fruticulose undergrowth close them.
