parkinsonii?

Thanks.

Hi Camilo,

I assume what we are looking at in the photo are seedlings, which appear to be a little elongated. I don't believe they are m. parkinsonii. There doesn't appear to be any evidence of white slightly curving radial spines. From the appearance that I see from your photo, if they are a normally taller growing species, then maybe they could be m.backebergiana subsp.ernestii. However, if they have been deprived of light at some stage in their development, they could be m. hahniana. Small plants are always difficult to identify, as they haven't yet got recognisable characteristics of their parents. Hope this is of some help.
