Years ago, i sowed this Mammillaria with fn TL 205




In catalogo "Mammillaria Reference Collection - 2010"
TL 205 is Mammillaria albilanata ssp oaxacana
Here a photo of Mark Masterson...




From Thomas Linzen list, 205 is....
205 M. aff. juxtlahuaca - San Miguel Tlacotepec Oax.

hi Maurillio,

m. juxtlahuacensis is a var. of m. lanigera which has subsequently been lumped into m. albilanata ssp. oaxacana by Hunt.  Mark Masterson's plant naming is more up to date, whereas Linzen prefers the older name. They are all the same.

Thanks for the exhaustive explanation.
Now everything is clear.

This is yet another example of the difference in the approach to species names between the Cites Checklist issued by the IOS (and updated in the Cactus Lexicon) and the mostly German approach. The IOS, being mostly comprised of professional botanists, tend to focus on the commonalities between plants and so lump together plants into species and have fewer subspecies. The alternate approach focusses more on differences, and so needs more names.

The important thing is to know what a name means, and if it has been combined with another. I tend to favour the IOS approach, but keep in my records (and in my labels) if it is a plant with a different name.

This example of plants which have been lumped into M. albilanata ssp. oaxacana is a classic case in point.

I know your point of view, Chris.
But perhaps for the gallery is a good thing to publish all the possible interpretations.
The search for a title will be in this way easy...

Yes, of course, I have no problem with the use of such names in the gallery. You are right that it makes searching much easier.
