Variability and diversity of B. reinwardtii var. reinwardtii, an important plant species, in its natural habitats in Kerala has been analysed based on the observations on seven growth characters recorded from seven accessions of the species distributed across Kasaragod, Kannur, Kozhikode, Wayanad, Malappuram, Palakkad and Thrissur Districts of Kerala State, India. Among the seven characters studied all the characters showed statistically significant variations between populations. Highly significant variability in the case of morphological characters indicates the strong genetic base of the plant species in the field providing it the genetic potential to overcome the threats of fragmentation and extinction in the study area. However, B. reinwardtii var. reinwardtii being a fragile and herbaceous annual, drastic alteration in their habitats and climate change can pose serious threat thus making it rare and vulnerable in future.
