206 WEST AFRICAN FORESTS AND FORESTRY 



leaves, rather small white flowers and large flat pods containing 

 five or six discoid seeds. The valves of the pods curl up after 

 dehiscence, and young seedlings spring up vigorously where not choked 

 by grass, farm clearings in Zaria province being often quickly occupied 

 by them. 



A coarse red resin exudes from injuries or punctures of the 

 bark. 



Isoberlinia Dalzielii, Craib et Stapf. Fara doka. 



Another new species of similar occurrence and habit, differing in 

 having a more grey appearance associated with a slight pubescence, 

 leaves not shining and pods less smooth. A species of the wild silk- 

 worm, Anaphe Moloneyi, and perhaps others, are found on them. 



Pterocarpus erinaceus, Poir. Madobia ; " Senegal Rosewood," 

 " African Kino," etc. 

 A tree generally of 30 to 40 feet or more in open savannah forests, 

 easily recognized by its bright yellow flowers, the regular venation 

 of the leaves, and the bristly, flat, one-seeded pods. The blood-red 

 resin is a variety of Kino, and in districts where the Camwood is 

 not found, the bark of Madobia is sometimes sold as a substitute. 

 The wood is hard and fine-grained. 



Cassia Sieberiana, DC. and C. ; Kotschyana, Oliv. Marga or Gamafada. 

 These are small trees with conspicuous yellow flower racemes, 

 having a superficial resemblance to laburnum. They are abundant 

 in the dry savannah regions as well as in savannah forest, and flower 

 freely in the dry season. The pods are long and cylindrical and do 

 not dehisce. . Cassia Arereh, Del., is similar, but the leaves are more 

 acuminated and the pods split up longitudinally. 



Detarium Senegalense, Gmel. Taura. 



A good timber tree in the mixed deciduous and higher savannah 

 forests, as also in the mountainous peninsula of Sierra Leone. Fairly 

 large specimens of timber dimensions occur in the rocky forest over- 

 looking Lokoja, but the Hausa Taura, hitherto identified as botanically 

 the same, is of a very different habit, abundantly represented in the 

 open bush savannah as a shrub or small tree having somewhat flattened 

 fruits, oval, less succulent than, and one-half or one-third the size of, 

 those shed by the forest specimens. 



Tamarindus Indica, Zinn. Tsamiya ; " Tamarind Tree." 



A very familiar tree in the northern Hausa States and Bornu, 

 as well as in French territory to the north, but much less common 

 on parts of the border-line between Southern and Northern Nigeria, 

 so that probably its actual distribution is local and interrupted. Barth
