A wood anatomy study was carried out on 10 Durio species. Three species, namely D. griffithii, D. grandiflorus and D. excelsus were included, and these species were previously placed in the genus Boschia. Findings have shown presence of prismatic crystals in chambered and non-chambered axial parenchyma in seven Durio species studied, whilst silica was absent. However, in the other three species (D. griffithii, D. grandiflorus and D. excelsus) silica was present, whilst crystal was absent. The presence of this mineral inclusion in these three species was not good taxonomic character at generic level and cannot be used to distinguish Boschia from Durio. Therefore, Durio is suggested to be maintained based on findings in this study. There is no diagnostic wood anatomical characteristic that can be used to differentiate species in Durio. As a conclusion the wood anatomy alone does not aid in delimiting species in Durio. |
