Hi Laurence and List,

Aaaaah, the nebulous picture becomes more clear. Science works in
mysterious ways.

It must be interesting (and fun) to have access to an institutional
collection. One could sift through the numerous specimens looking for
traits that stand out and/or features of interest. I wonder what first
caught her eye about this old Saharan OC. I wish Ms. Crystyl the best
of luck on her research and I hope we see her name more often in the
Bulletin. :)

Thanks for the explanation Laurence. :)

Best regards,

MikeG
