timbers was analyzed. The timber; Erthrophleum ivorense had the least water imbibition capacity of 7.2%, 10.0% and 15.4% at the stipulated times (0.5h, 5h & 24h) respectively. Spathodea campanulata with respective water imbibition capacity of 104.8%, 185.7% and 280.0% had the highest porosity index. From the results, Protea elliottii,after 0.5h and 5h water imbibitions had the highest porosity index of 136.6% and 198.4% respectively while Spathodea companulata’s porosity index at the same time were 104.8% and 185.7% respectively. The porosity index of Spathodea campanulata increased to 280.0% after 24h water imbibition while that of Protea elliotttii increased to 253.3% after 24h. This showed that Spathodea campunlata has the capacity of absorbing water over a period of time more than other timbers. The results also revealed an inverse relationship between water imbibition (porosity index) and ODD of fifty–two selected Nigerian timbers.
