Hallo Madcactus, that is a very nice Astro you got. ...aaaand with double flower! Wow!
I just wonder about the name. Is it possible that it is a A.capricorne...? Or are those names synonym...?

Yes, a synonym. You can see a list of former names here: https://caryophyllales.org/cactaceae/cd ... c0fcf7977c

According to Llifle: Astrophytum senile is a variety of Astrophytum capricorne, differing in its larger stems, which generally lack hair-flecks, and so densely wrapped with soft spines that the body is hardly visible, and looks like a dry grass bundle. Up to date many botanists don’t recognize the variety rank to this taxon which does not differ conspicuously from the other forms of the species.

Thanks MrXeric. Cacti sub-species and botanical names can get complicated. At least for me.

Well it took until 1st October to flower, but finally -

Hallo Gillinger,
that's a real nice Matucana madisonorum. Interesting with those long spines, never seen that before.
Is this a special variety?

Hi Spence,

Setiechinopsis tend to be short lived plants, over 5 years is a good age. However they are self fertile therefore plant a few seeds from those fruits to have replacements coming along. I bring mine indoors when in bud so as to not miss the flowers, otherwise when you go into the greenhouse in the morning the flower is over.

Not being long lived like many cacti no doubt they regularly regenerate from seed in habitat, therefore ev0lutionarily have favoured self fertility to ensure survival. No doubt outcrossing from time to time to retain fertility.

Hey Nachtkrabb. Sorry, only just seen this. Thanks. It was identified to me as "horridispinum", which makes perfect sense!

I'm well aware of this, I was starting to worry that I might not harvest any seed before they died. Now I've got 2 big fat fruits, probably hundreds of seeds. When are these fruits likely to dehisce?

Hi Gillinger, wouldn't call that name understated.

Maybe last (of my) flowers?

Really beautiful plants, I would very much like some in my collection. May I ask where did you acquire the seeds?

Seeds came from Mesa Garden. Even with a field number L1495.

Mammillaria pectinifera
Does anyone know if the seed pods are external, or internal New phone camera, need better lighting, background and top dressing

Beautiful plants Craig! I don't grow them (yet ), but they appear to be partially cryptocarpic:

Perfect description of the plant
Thanks

This M. pectinifera was one of my favorite plants for many years
it rotted right after I transplanted into the pot shown in this photo
winter transplant-not recommended..
