The aim of the present study was the phenological study of twenty poisonous trees, shrubs and herbs species found in different forest regions of Purulia district.For the study of these twenty poisonous plants five different phenophases such as germination, vegetative growth, leaf senescence, flowering, ripening of fruits were observed throughout the year and depicted in the phenogram for trees and shrubs. For herbs the phenophases are germination, vegetative growth, flowering, fruiting and death. This phenological observation revealed that among these twenty poisonous plants, most of the plants showed germination during June to July and new leaf formation occur throughout the year. In case of trees and shrubs maximum leaf senescence occurred during the months of February to march. Most of the herb species died between the months of November to march. Twenty poisonous plant species show flowering and fruiting at different times throughout the year.
