that I have not been getting email notifications from MO on either name changes or comments made on my obs. … Jason says some sort of horrific glitch whereby MO emails to users (some of us anyway) are being blocked as spam by some entity along the way, BUT they don’t even make it to the Spam Box. From now on I’ll be checking “Comments” daily in order to give timely responses to helpful mentors such as yourself. The name you proposed seems to make perfect sense to me as things stand now with this genus. Thanks for that also:)

Excellent obsie, Judie
