Dear Dave, Max Mary sue and all who have contributed... but esp Lindolpho Capellari Junior. WOW I immediately downloaded the thesis (after registering) and was /am quite boggled. With my limited Spanish and a Macintosh Portugese translation widget, I fumbled through the 3 page key beginning on P 99. Fig 16 on p. 103 " Morphological Characters used in the Key" is an exceptionally handy representation of each dichotomous state in the key and shows character differences for each couplet. I don't think I have ever seen this done better. He includes 20 species in the genus. Innes has 13 species (that don't match Senor Capellari's) and Mabberley (my 'Bible") also has just 13 species. This will keep me busy for a while. Thanks to all. Jim W. -- Dr. James W. Waddick 8871 NW Brostrom Rd. Kansas City Missouri 64152-2711 USA Ph. 816-746-1949 Zone 5 Record low -23F Summer 100F +
