OK, here's my guess on your photos. I'm sure others will join in the guessing game. Some are a bit difficult without flowers, or indeed, knowing the pot size for the plants shown. But it makes it a bit harder that's all Smile

#1 looks like M. longimamma or maybe sphaerica
#2 has bristles in the axils, and though the spination isn't "typical" looks like a form of M. mystax to me.
#3 is a form of M. formosa. The description in Pilbeam is very specific on M. formosa - 6 central spines, but this species varies very considerably and this looks to me like a form of which I have a couple of plants. Check Rog 326 towards the bottom of the Formosa section in the A-Z gallery
#4 I am unsure about, though it could be M. backebergiana
#5 looks like M. rhodantha
#6 could be the white flowered form of M. zeilmanniana. I don't think it is M. mathildae, which is another white flowered member of the Stylothelae. Did you notice what the filament colour was when the flowers were open? M. mathildae has pinkish filaments.
#7 another probably poor guess on this one - M. pettersonii? possible what used to be called apozolensis saltensis?

Hi Mike,
Here are my suggestions.
1. sphaerica, because of its untidy growth.
2. grusonii- papasquiarensis.
3. ritteriana a form of chiononcephala. Outside chance of haageana san-angelensis.
4. I too am unsure, but I think Chris's call is good.
5. This is what I believe to be apozolensis saltensis (petterssonii)
6. crinita. Probably zeilmanniana
7. I believe this to be petterssonii.

2: Could indeed be mystax, the long curving spines at the top are an indication for it. If the flowers are red, then that is another good indication for mystax.
3. M. pseudoperbella might be another candidate, but the Rog 326 form of formosa is also possible.
5. M. pringlei (a rhodantha form if you are a lumper, but in my opinion it is characteristic enough to warrant a specific status). It also looks a bit like M. apozolensis saltensis, but the spines on my saltensis plant are not as symmetrically arranged as on my pringleis. Also, pringlei will become somewhat columnar, whereas apozolensis saltensis remains globular.
7. Could indeed be apozolensis saltensis, but the plant is much too small for a more definite ID.

Wolter ten Hoeve.
