Hey, dthomas,

Thanks for reporting from Montville!

One thing that would strengthen your evidence in future observations would be including size references and measurements - both of the overall plant and of individual leaves. For this species especially size is an important bit of data to record.

I look forward to your next submission.

cheers,
