Vernac. names. — Ogaba (Benin, Thompson, Unwiri) ; Furuduga ? 

 (Sierra Leone, Smi/the). 



Benin ; Obeyon near Efcoi River ; confluence of Quorra (Niger) and 

 Tchadda (Benue). 



Wood, hard and red (Thompson, Col. Rep. Misc. No. 66, 1910, 

 p. 21). 



Samples of gum from this species are exhibited in the Museum, 

 Kew, sent by the Royal Niger Co. in 1887. 



The tree occurs in the freshwater swamp forests of Southern 

 Nigeria and the Gold Coast. 



Daniellla, Bennett. 



From time to time various specimens of resin-yielding trees have 

 been received at Kew from W. Africa, and in some cases the speci- 

 mens have been accompanied by samples of the resin. It has been 

 found that several new species of Daniellia are represented, and 

 though it appears probable that they may all yield .valuable resins, 

 the question is at present somewhat uncertain. One of the principal 

 and best-known sources of the ogea resin of commerce appears to be 

 the Daniellia thurifera of the Flora of Tropical Africa which has 

 now been referred to the new genus Paradaniellia .

 on each side, conspicuous on both surfaces, interarching well within 

 margin, up to 3J in. long, 1 in. broad ; petiolules 2\ lin. long, pedicels
