What do you mean by "mixed up some seeds". Did you buy a seed mix, or mixed up the species names? If you purchased species. what species did you buy? This may help narrow down the possibilities. In fact I received lots of unidentified seeds from someone and mixed up with other unidentifie...

Thank you very much anttisepp....lets see how it develops

..maybe hybrids? Your Mamm's long spines and small flowers are atypical for "straight up" deherdtiana var. dodsonii, so I'm leaning more toward hybrid. The dodsonii side of its genetic heritage seems apparent, but unfortunately I don't know Mamms well enough to guess at the species that c...

I mixed up some seeds and have no idea of the ID of this Mammillaria. Any input will be appreciated Thanks in advance IMG-20230327-WA0030-01_copy_768x768.jpg IMG-20230327-WA0027~2_copy_768x772.jpg IMG-20230327-WA0026-01_copy_768x768.jpg What do you mean by "mixed up some seeds". Did you b...

So it's been a long time since I've posted here something about my sowing experiences. I have sowed lots of seeds and get more confident. I stopped counting the germination and survival rates and took some time to notice that things were not going well.. When you sow 10 seeds in the pot you can easi...

Thank you Steve. It is hard to "decide" if it is just variability when you dont know the species very well.
However which such kind of flowers it couldn't be many other things...I think
..maybe hybrids?
Thanks

M. dodsonii? Despite the long central spines and smaller flower?

So here are more and better pictures. Until now two names have been suggested: rubrograndis and deherdtiana. We should be able to distinguish them, shouldn't we? I noticed now that there is some wool in the axils...if it helps. Thanks for any comments! 20230402_123431_copy_600x800.jpg 20230402_12343...

Interesting. At first sight I said to myself "pilcayensis". Next I saw the hooked spines and said "no". Interesting to think in hybridization with the more closedly related species of the same group. On the other hand: there is not any other Mammillaria with hooked spines it coul...

Slightly curved central spines... smaller flowers... don't sure.

Agreed...thank you

Thanks Lucy, Tom and anttisep! Until now ... no definitive ID. Anttisep why are you unsure about rubrograndis? And what do you think about deherdtiana? Tom: I agree; but it shouldn't have more radials? Lucy: I am between deherdtiana and rubrograndis because the flowers are bigger than the average Ma...

Any input will be appreciated

Thanks in advance

They are so beautiful

Thank you Spence.

Yes. I think you are right
Thank you for the insight!
