GUIDE TO TIMBERS OF NIGERIA 35 



too thin to taper appreciably ; number per mm. 22-24 ; 

 proportion of the wood about one-quarter ; cells contain 

 globules. 



Ground-tissue-cells doubtfully visible with the macroscope. 



Rings apparently denned by bands of very dark dense 

 tissue ; contour regular. 



Radial section. The P. (a) in light lines is readily visible. 

 Vessels frequently forked and in some cases a pore will branch 

 like the cross-over road of a railway. They are mostly 

 empty with bright linings, and a little resin here and there. 

 The rays produce a matt effect which is just discernible, the 

 individual rays being just visible with the lens. 



Tangential section as the radial, but the P. (a) broadens out 

 into prominent hoary loops. The branching of the vessels is 

 still onore obvious and some are very crooked. Rays visible 

 with lens, very minute, in parallel and similar in height (about 

 ten cells), or as long as the diameter of a large vessel. 



Density, 0-74 to 0-753, or about 46J Ib. per cubic foot. 



Paradaniellia Olivierii, Rolfe. Leguminosse : Csesalpineae. 

 Gen. No. 1949A. 



Synonyms : P. thurifera, Oliv. ; Daniella (or Daniellia) 

 thurifera, Oliv. (non Benn., which = Cyanothyrsus, but which 

 now according to Stapf should form the new genus Afrodaniella. 

 See Chevalier, 1917, p. 164). 



LOCALITIES. Sierra Leone, Gold Coast, Togo, Nigeria. - 



Our specimens were sent to us under the name of Daniella 

 Olivierii, hence we give vernacular names separately. Another 

 received as Daniella thurifera, J. J. Benn. No. 4301 HS. 

 " Bu " from the Sudan, agrees except as to colour, which is 

 distinctly redder.
