چکیده
! e analysis of the architecture of Buxus vahlii Baill. (Buxaceae) in western Puerto Rico is presented. Two populations growing in diff erent environmental conditions were studied: one is a coastal forest in the municipality of Rincón and the other is a mountain forest with karstic formations in the municipality of Isabela. ! e growth pattern in Buxus vahlii follows Champagnat’s model. Four stages of development were identifi ed: seedling, juvenile tree, mature tree and senescent tree. ! e stem and branches of the tree are sympodially built by the superposition of mixed orthotropic axes. Two diff erent crown shapes have been recorded in B. vahlii in Puerto Rico: in the Rincón forest, the shape is laminar, while in Isabela, it is in-between a funnel and cup shape.
