Right Larry, that is my doubt too, two separate species or the same? Anyway this is my Gymno something. (should I remove the label mihanovichii?)

Here is possibly the best description of the situation that I have come across. I encourage people to at least be familiar with the situation, whether or not they choose to use the official names.

So, most "mihanovichii" are officially stenopleurum. How many times did you see a dirty yellow flower? G. friedrichii is not an official taxonomic name, if it were it would refer to plants with bold pink flowers which are rarely found.

Here is a link that might be useful: Cultivar article

I have a G. friedrichii with pink flowers. I've had it for around 5 years and I don't think it's grown one bit! Is it supposed to be this slow of a grower?
