Hi Roy,
V. Gnana Kumar is an older cross...from 1970. When I looked it up, I didn't recognize the hybridizer: they registered 7 crosses between 1968 and 1972, with none having pics in Orchid Wiz nor did any of them have awards. This might be because these hybrids were bred by a hobbyist, which translates to there might not be many in existance.
Yours is really pretty with the green to it. Mine is more of a bright yellow. I notice the scent the most in the early evening and into early morning, but not during the midday. It is really a great smell too!
