Abstract: In order to comprehend floral organs and pollen biological characteristics of Okrong,the biological characteristics of their flowers,gender ratio and pollen morphology were observed,and the pollen fertility was tested.The results showed that:（1） The flowers’ types mainly were male and hermaphrodite flowers,they were small but great amount;（2） The proportion of hermaphrodite flowers was low,only 17.99%,but the inflorescence ratio at the south direction reached 47.83% in the early flowering season;（3） Their anthers were full,each anther containing 408 pollens;（4） The pollen viability of staining was lower,only 14.02%.According to the pollen morphology and size,Okrong flowers can be divided four kinds,which are large oblong oval pollen,medium oval pollen,small nearly round pollen and small irregular shaped pollen.
