176 COLONIAL REPORTS MISCELLANEOUS. 



Quite a large proportion of the trees found in this type have a 

 very wide range, and are to be met with all over extensive tracts of 

 country that possess a climate with a much smaller rainfall; in 

 such areas, however, owing to the greater humidity brought about 

 l>y the hilly nature of the country and the existence of deep 

 sheltered valleys that are frequently occupied by perennial 

 streams and swampy soil, the trees in question are still able to 

 thrive, hut with many of them the departure in habitat from the 

 continually moist environment of the rain forest is associated with 

 a more pronounced xerophilous habit and a greater periodical 

 defoliation Some species remain evergreen throughout their 



range. 



The following trees are found distributed about the country 

 from the centre of the rain forest region (Lower Tano and Ankobra 

 River basins) right up to the borders of the savannah forest region 

 in Northern Ashanti. 



The Odoiini (Chlorophora c.rcelsa). 



The Waw-waw (Triplochiton Johnsoni-i). 



The silk-cotton tree (Eriodendron anfractuosurn). 



The Dahomah (Piptadenia africana). 



The Off ram (Terminalia superba). 



Tlie Einril (Terminalia species). 



The Awania (Ricinodendron africanus). 



Other species with an almost equally extensive range are invari- 

 ably associated with the presence of moister soil such as occurs 

 near the beds of streams, edges of swamps and similar collections 

 of water. Their distribution is governed by edaphic influences. 

 and they keep reappearing throughout extensive stretches of 

 country. 



Including species that are common to most of the climatic 

 formations, the more valuable plants from the rain or moist 

 tropical evergreen forests of the Gold Coast and Ashanti are 

 arranged below in accordance with the character and comparative 

 value of the products they yield. 



(a.) Species yielding first-class timber fit for export to Europe 

 and oilier countries,. 



i. Mahoganies. 



The Difbini (a new species of Kliaya). 



ii. Cedars. 



The Punkwa or Penkwa (Pseudocedrela cylindrica). 

 The Tiama-Tiama (a new species of Pseudocedrela). 

 The Basse (undescribed species of Guared). 

 The Pcbedum (Loroa Klaineana). 



All the above trees belong to the natural order 

 Meliacere. The timber of the Pebedum closely resembles 

 teak in colour and structure. 



The Odoum (Chlorophora excelsa). 



iii. Other species :- 



The N'yanl-oi) (Heritiera utilis). 



The Jihinire (a lofty species of Detarium).
