Floristic Composition of Tree and Shrub Species of the Jaraguá State Park, São Paulo - Sp, Brazil

The objective of this study was to characterize the floristic composition of trees and shrubs of the Jaraguá State parkland (PEJ), contributing to the knowledge of its biodiversity. Reproductive botanic material was smooth along three trails during a 12-month period.
