We'll kovacii and this little guy are simular, but they are also very different, size being the biggest difference. These guys bloom sequentually (sp?) (techincally so does kovachii, but not as often as these guys, andrettae is like a fisheri or schlimii, they can bloom for a few weeks, kovachii produces 3 blooms and thats it).
The leaves are very different, closer to a fisherii or besseae leaf then to kovachii or schlimii.
The plants are very small. I think people will really enjoy these little guys.
