Chinar, Platanus orientalis is a huge, widely distributed, and long-lived deciduous tree native to the eastern Mediterranean. It is the only species of the Platanaceae family found in India and grows throughout the valley. Since ancient times, this particular species has garnered fascination and reverence, leading to its continuous examination and admiration. However, the information related to its floral biology is meagre. The floral biology of P. orientalis is crucial to understanding its reproductive mechanisms and ecological interactions. The present study, therefore, aimed at investigating the floral characteristics of P. orientalis. For this study, seven young sexually mature trees were selected to study the floral characteristics. It was revealed that, in general, male flowers often emerge earlier than female blosssoms. The position of the male flower is always proximal and that of the female flower is distal when present on terminal branches. The average male female ratio recorded was 7:1 and the ratio between pollen and ovules on average was 9550 to 1. The pollen-ovule ratio is a fundamental reproductive parameter that provides insights into the reproductive strategies and ecological adaptations of plant species. The floral biology of P. orientalis demonstrates its adaptation to wind pollination and efficient seed dispersal mechanisms. This knowledge enhances comprehension and aids in gaining a deeper understanding of the reproductive strategies of P. orientalis and its ecological significance within its native range. Research in this field can help in developing effective conservation strategies and utilizing this species for research purposes.
