Map of the World showing the Tropic Circles which at 23.5 deg. distance north and 
south of the equator border the Tropic Zone. This region between or near these 
parallels is marked by its torrid climate and luxuriant vegetation, modified of course 
by altitude and precipitation. Guided by the lines of latitude on this map, and the 
listed tables on elevations, temperature and rainfall, a fair idea can be formed about 
climatic background and geographical distribution of plants in their native countries,
