Mammillaria ID (with flower) (new pictures)

Post by mmcavall »

I mixed up some seeds and have no idea of the ID of this Mammillaria.

Any input will be appreciated

Thanks in advance

The flowers are a little small, but the spines look like Mammillaria deherdtiana

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 Mammillaria flowers
. Too big for perbella, I think.
Well..
Maybe I should come back with better pictures of the spines
Thanks for commenting

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

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!

From Llifle.com -- Mammillaria deherdtiana on the left and deherdtiana var. dodsonii on the right:

Not sure if you have a dodsonii, but yours may just be showing some variability in the species.

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

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 contributed the other side of the hybridization. Whatever you have, it's a pretty one.

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.

Sometimes very young and small plants have smaller atypical flowers especially in combination with deficiency of watering. I see very close features of dodsonii and hope time will show is this suggestion false or true.

In fact I received lots of unidentified seeds from someone and mixed up with other unidentified seeds...hard to know but thanks!
