The climate is multifold and dominated by a rainfall distribution which is southwest - northeast in zonation. As the climatic zones and the vegetation are closely related, they can be discussed together. The general account of these zones given below will serve as a frame of reference for the subsequent description of localities in which collections were made. l) Forest zone The large forest belt occupies the southern third of the country with the exception of the narrow coastal savanna zone extending eastward from Takoradi (Dixcove). Though the north - south section of the Volta valley interrupts the high forests of the forest zone, its transitional type vegetation separates the vegetation of the coastal savanna from that of the northern savanna zone. The northern boundary of the zone is less sharply marked than the southern, and it is connected in the west and east with the corresponding zones of the neighbouring countries. The northern limit of the zone reaches about the 7th northern latitude, it runs south - eastwards from the western third, and follows the northern fringe of the central upland. The forest zone is connected with the northern savanna zone by a distinct transitional belt. The area covered by the forest zone is about 25,000 square miles (65.000 km

). The whole area is under the régime of two rainy seasons, but comprises two subzones, according to the amount of precipitation. a) Rain forest subzone This occupies the southwest corner of the country, westwards from the latitude of Dixcove (near Busua), and stretches northwards to about the level of Tarkwa. The subzone, and also the isolated areas with similar vegetation, coincides with an area having a yearly precipitation of 65 inch (1,650 mm) or above. The highest value of precipitation is around Axim with a yearly average of 84 inch (2,130 mm). The
