Study of variation in petal number and relative abundance of Nyctanthes arbor-tristis L. flowers

The flowers of Nyctanthes arbor-tristis L. have a wide spectrum of biological activities. The current study encompasses the variation in petal number and relative abundance of night-flowering jasmine flowers. The observed petal number of this flower ranges from four to nine. The most abundant variety is the flowers with six petals, which comprises 60.69% of the total number of flowers counted. The four and nine-petalled flowers are extremely rare making only 0.02% each. This study represents the statistical data obtained directly from the observed natural phenomenon. However, this short communication warrants further investigation to evaluate the correlation of petal numbers of the flowers with other physico-chemical or environmental parameters.
