I focus on several ecological and evolutionary issues of Oxalis corymbosa (紫花酢漿草）, such as breeding system （heterostyly，花柱異長）, ploidy number (染色體數) , and development of male and female sexual organs （雄、雌花器發育與形態）. This species ia an exotic species in Taiwan. Also, I try to find out which environmental factors to cause few populations of O. corymbosa in south Taiwan （植物生理生態學）.
Now, I want to learn more knowledge from identifying the plant species and enjoying the beauty from Taiwan plants.
