Steve,
Do you mean 'Orchids', the AOS publication, or all the 'Orchids' magazines out there?
I know that Eric A. Christenson published his work on describing the new species of Phragmipedium (P. peruvianum) in the AOS 'Orchids', but my colleague Stig Dalstrom, Bruce Holst, and Ricardo Fernadez published the supplement to Selby Garden's 'Selbyana', their scientific journal...
Then I think the next mention of Phrag. kovachii was in the month after Eric A. Christenson published Phrag. peruvianum, where the AOS makes a correction in a small paragraph stating that Phrag. peruvianum is reduced to synonomy of Phrag. kovachii, which was described by Dalstrom, Holst, and Fernandez... then Carl A. Withner did some sort of Phrag. kovachii DNA Analysis in an orchid magazine (forgot the name of it)...
I have some of the magazines that mention Phrag. peruvianum and Phrag. kovachii, but looked through the entire 2003 year of orchid magazines myself for Phrag. kovachii articles... these are all I remember, hopefully someone else will post the absolute information... my articles and books are elsewhere at this time...
