15. CARAPA GUIANENSIS (see last number). 

 FRONTISPIECE No. 15. 



This wood is simply a variety of the last-mentioned species; 

 in fact, Mr. Spence, who assisted in the collection of these woods, 

 says that the two are the same. In Mr. Bell's report they are- 

 dealt with separately. 



Alternative Names for this Variety. " Lowland Crabwood, 

 Caraba" (White) (2); " Andiroba branca, Caraipa " (21). 



This wood has a wider and more sharply denned Sapwood, 

 otherwise all characters agree with No. 14.

 30-40 ft. in length " (2). Fissile, takes nails badly; planes easily 

 but indifferently ; turns easily but badly ; polishes but moderately 

 well. Export value doubtful. Sometimes confused with tha 

 Carabas, Nos. 14 and 15, on account of the similarity of the colour 

 and name. The structure is, however, entirely different.
