Summer 2017 in my greenhouse

It is getting hot now in the greenhouse, door and windows are open and the fans are running

The first two plants I have bought last year from an former AfM-Member from southern Germany.

Mammillaria priessnitzii Rog 109 - MEX-70, km 177, direction Rio Verde, SLP.

Mammillaria mollendorffiana K 253 - HGO-27, Cardonal - Nicolás Flores, s. Seminario, Hgo.

This plant comes from André van Zuijlen, bought 2015 at the ELK in Blankenberge.

Mammillaria formosa (sempervivi) AvZ 249 - La Cardona Zac.


A dichotomously dividing M. perbella (morganiana), just one flower.. bought last year at the ELK from Dubenkaktus (CZ)

This nicely spined M. compressa was a discovery at Andreae Kakteenkulturen in the Odenwald, Hessen.

Mammillaria compressa - San Francisco. SLP.

And the last one a M. theresae Rog 235 from the Rogozinski collection.

The new plants look in good shape.
I would label the André van Zuijlen plant as M. formosa. The location La Cardona would also fit with that.
The M. morganiana looks very short-spined. The plants that I saw in nature have longer spines. I consider M. morganiana as a form of M. parkinsonii.

The plants of M. parkinsonii and M. morganiana have pale, yellowish flowers with a reddish centre stripe. This looks an unusual colour for either of suggested species, but maybe I haven't seen enough to understand the variabilility of their flowers?

Chris, I fully agree with you that the flower colour doesn't fit for M. morganiana. However, Reppenhagen does state in his book: Blüten gelblich bis rosa (flowers yellowish to pink). The M. morganianas that I saw near Bucareli always had yellowish flowers.
Was there a location or a field number attached to that Duben-plant? That might help in identifying it.

Wolter.

Thank you Wolter! I've corrected that.
I am still dreaming of seeing Mamms in Habitat, but I have to be patient maybe in some years..
Yes, that is what I have rode about the flowers, too. No filed number or location and I have looked on their website for some information.. Do you think it is maybe a M. albata?

My thoughts went to M. klissingiana, but M. albata could also be a possibility. However, klissingiana and albata do not divide dichotomously, as far as I know.
Another possibility could be M. perbella, which does divide dichotomously.
It is a pity that there is no location or field number given for the plant, that would certainly have helpecd in identifying it.

Wolter.

In ELK 2015 i bought this AvZ 246 - Puerto Madero, Zacatecas.
Labelled Mammillaria sempervivi is probably another Mammillaria formosa..
P.O.C.

Yes, this Puerto Madero plant is M. formosa. I found M. formosa there too, and I gave it the field number WTH 622.
