To answer your question regarding the total number of toxic plants identified by Bhatia and his colleagues from the Udhampur district in India, I would need to consult specific sources or research findings, which I don't have access to. However, if you are looking for a specific answer among the provided options (50, 60, 70, 90), I recommend checking the relevant academic papers or articles authored by Bhatia and his colleagues for accurate information.

If you're unsure about where to find such resources, you might consider looking in scientific journals or databases like Google Scholar or PubMed. Alternatively, you could visit a library that has access to journals related to botany or toxicology.
