OldGardener,
No-one is upset or offended at all. I truly appreciate your research and information on these two Dietes! After reading your posts and comparing photo's in our database and reading and looking at other photo's on the internet I do believe my photo's belong to D. grandiflora, so I'm going to move them over to the correct entry right now.
Thank you so much ... it is folks like you who are helping to keep our database up to date and correct ... and your effort is much appreciated!
