Comparative Systematic wood Anatomical study of Eleven species of Combretaceae in Nigeria.

A comparative systematc wood anatomical study of eleven species belonging to four genera in the family Combretaceae was carried out. This was with a view to identifying characters of taxonomic value in the diagnosis, delimitation and subsequent identification of members of the family. collection of accessions of the species was made from different parts of Nigeria. Transverse, Tangential and Radial longitudinal sections of the stems of the species were carried out using Reichert sliding microtome. Both qualitative and quantitative charcters of wood anatomy of the taxa were observed and document. quantitative data were subjected to Analysis of variance, Single linkage Cluster and Principal Component Analyses.
Results revelead that wood in the eleven taxa is generally diffuse porous. Coarse grained alform confluent paratracheal parenchyma delimits Terminalia ivorensis from thebrest of the taxa. Also vasuclar ray types is classificatory in the taxa. Vessel diameter was hghest in the member sof the genus Combretum while the least vessel diameter was recorded in Anogeissus leiocarpus. other quantitative wood characters were significantly different among the eleven species.
