Vegetative description of three Aquilaria (Thymelaeaceae) saplings in Malaysia
Plants` reproductive parts are most important for species identification. However, trees such as Aquilaria species take many years to mature and produce flowers and fruits. Inconsistent and infrequent flowering periods may cause additional hindrance to classical identification. In this study, descri...
