stilldew,
Strange, I looked this one up in the data base and there is one listing for 'Middendorffii' and one listing for 'middendorffii'.
'Middendorffii' shows to be "ORL2: Orange red light with markings, bitone, or polychrome" . 'middendorffii' has very little info, wonder if that is just an entry mistake.
stilldew's looks yellow to me.
