No, Wolfgang doesn't seem to be using email much these days.

Hi, you've been busy! Great plants.

Nice plant!
If I had to choose between ssp. coahuilensis and ssp. albiarmata, I would go for albiarmata because of the tidier form of the spination, making a much neater plant.

I've had seed from Koehres over the years. I gave up on them because of poor germination. Many years ago, they had a lot of Reppenhagen named seed available, and I had no issues. I don't know if their problem is old seed or poorly kept, but 10% germination rates aren't what I get from many other seed suppliers.

M.albata has been referred to M. hahniana as well as M. geminispina ssp. leucocentra. You can see the details of this in the A to Z section under A. Your plant looks to me to be closer to M. hahniana than M. geminispina, but I think its difficult to be sure. I try to grow plants with some kind of location attribution, as these plants are quite variable in size, shape, and wool.

Certainly a Coryphantha, perhaps C. cornifera,

I really don't think it is rhodantha. Not 100% sure by any means, but it looks like one of the many forms ofM. compressa, maybe centralifera.

I think that the red spined Mamm in your second post could be one of the Spinosissima family. Quite variable.

The flowers look possible, though th elong axillary hairs are soething I've not seen of that species. Its a puzzle still for me.

You're righgwigh haageana for the first, a very variable species. Asfor the seond, it looks as though the cenral spine is curved towards the apex. That suggests M. wagneriana to me\
The thirdplant is really nice, but Ican't place it at the moment.It might well be a sport in which all colour in the central spines has gone.That sometimes ocurs with mass production cultivation.

I'm sure the members here will try their best to help!

I had understood that one of the distinguishing characters between magnimamma and compressa was that compressa should have bristles as well as wool in the axil, whereas magnimamma just has wool. The would, I think, support this plant being a magnimamma, but I'm not sure the photo is goodenough to see clearly.

Yes that would appear to be an offsetting form of M. haageana. I think that ssp. schmollii would be approrpriate.

Great plants, and so nice to seethem in flower. I was surprised at the pink flowers on the Charco Blanco formosa. Always surprises in these plants.

I also saved a lot of ML pictures some have been also sent to me by Wolfgang Plein, which have not uploaded to the mammillarias.net website. Anyways I also have not every picture. Maybe we can swap pictures? I will upload a list which ones i have saved.

Did anyone save the data from the Fieldnumber Database of Franck Martin?
Thats what I am missing the most..

Certainly, let me know which you want, maybe send me your email. And no, I don't have a copy of the fieldnumber database. Which collectors did it contain? I have a number of collectors lists which Wolfgang sent me some time ago, but tere is also the BCSS Field Number database which contains many Mammillarias. Is that of help to you?

So here is the image of ML690 saved from the old mammillarias.net website.



Very yellow spined indeed! It looks as if the photo was taken late in the day but still no real sign of brown in the spines.

Hi Wolter,
I don't think we'll see the new site developed. I've emailed the author a few time byt not had a reply.
However......back in 2008 I saved a number of the Lacoste images from the old site, and still have them on disk. The file names are from ML02 up to ML735, some gaps inevitably, but 496 images in all.
Are there any specific one you'd like which I could send to you. They aren't high quality jeps but might help. If there are then please email me.

Hi, and welcome.
I would say that the first few photos show M. muehlenpfordtii, paricularly nicely spined plants. The bent over plant is, I think, M. matudae, and if its the same plant in theclose up of the top with red flowers, then that also is, I think, M. matudae.
I can't see clearly enough from the photo exactly what the spines are but the multi-headed, dichotomously branched plant with the odd pink flower is probably one of the many forms of M. perbella.
I don't recognise the next one, also dichotomously branched, with hair in the axils. I'd be tempted to suggest a form of M. karwinskiana, or beiselii, but I've never seen one with such long spines.
The next inage shows, I think, M. albilanata, again a very variable species, and the smaller plant is either anoher perbella or a microthele.

I'm sure others will probaly correct me, as though I love growing these plants, I don't have a perfect record at identification, by a fair way.

It's an Echinocereus, probably either stramineus or enneacanthus (more likely).

Wow, what great phptos of lovely habitat plants. I sowed a couple of packets of E. vivipara seeds, which were stated to be Canadian, one from Dorothy and the other from Old Man River.They are too youg to see just how different they are from my Arizona seed grown plants, or indeed from each other. But apart, perhaps, from an Opuntia in Ontario, these must be the most northerly cactus plants.

It certainly has something of polythele in it, though I've never seen a polythele grow so long. I have heard that there is a cross between polythele and mollendorfiana, though I was told about that in 2005 or 6, I think. However, I've never seen one, though it would seem possible.

1. Not sure, could be hahniana r a short spined geminispina
2. Yes, I'd say rhodantha, maybe ssp. pringlei or aureiceps
3. First glance, I thought that's not a Mamm its a Parodia. The look of the plant and a hooked golden central (1) didn't ring any bells. It also looks like the growing point is elongating.
4. Could be a karwinskiana.

But not entirely sure.

Dear Vladimir,
Many thanks for the "walk" through the greenhouses. What an amazing mix of seedlings and beautiful mature plants. That Astrophytum caput-medusa is amazing!
As many have said before, I wish you safety and health in what must be such difficult times. The resilience and fortitude of your people is amazing.
Chris

Both the main head and the smaller one appear to have been attacked at some stage, with the resulting scar healing white. I don't know if the damage was due to a pest or a blow of some kind, damaging the growing point. In your second photo, there does appear to be something white, not scarring, on a few tubercles.
If further investigation doesn't show any living pests, then grow on and keep it in light and warmth. I can't give you watering advice as I don't know what country you are in, but from the rather shrivelled looking little offset is anything to go by, when it is your growing season, do give it more water, which should drain through quickly.

Offsets are what I call new heads, usually from the base of a [lant, so that it forms clumps of "heads". Some people call them "pups".

I hink that it certainly looks like M. haageana, but ssp. schmollii is a form that offsets, which your plant does not appear to be doing. Its a very variable species, with a number of subspecies names given to it, but many have been discarded. I have seen these plants in habitat and formed the view that this species is quite variable even within a specific population.

In sequence, here are my guesses.
M. formosa (maybe sempervivi), M. polythele, M. crinita (wildii), M. magnimamma, and not sure, maybe another form of magnimamma.

One of the many forms (and flower colour) of M. formosa, I'd suggest.

Whilst my first thought was one of the many forms of magnimamma, but on closer look it could be a form of polythele.

There's a lot of mixed views on pseudoperbella as a valid name. Is it perbella related or mre formosa related? Its a nice plant whatever it is called, and pseudoperbella is an acceptable name to me. See the images on the A-Z section and find pseudoperbella. Whilst the spination varies, I think its the same species.

Very nice.

Yes, watering after a period of dryness can promote flowering. It's one reason I don't water too frequently.its like the plant says to itself "at last, food! Now I can become fertile as there will be water for my baby seeds".

THis is a common question, but the answers can be quite varied. At the moment I have boolii and its ilk flowering well, and the grahamii, sheldoniii, mazatlanensis complex also coming into flower. I don't feed them much, but they do get good winter light.So my recommendation would be dry them off in early October, keep them cool,over winter (4-5C) in good light, restart watering (small amount at first) and in late June onwards you shoud get them into flower. I water about every three weeks, and sometimes a good drench can give them a kick into flower too.

I'd like a large image, but from what I ca see then yes, probably bombycine, needing a lot more light!

Yes, I'd go for albilanata, maybe ssp. oaxacana wich is the one grown most, as the species is a bit more delicate.

Welcome back then. There are tips about inage hosting in the Guidance section. I think its up to date, though sometimes there are changes inthe process that mean I have to rework it. If you can follow it then that's great, if not then message me with how far you've gor andI 'd hope to guide you through. Once done its fairly intuitive the next time!
Regards
Chris

Yes, I'd go for M.crinita, as the spines and flowers are different, soft flexble spines, almost hairy, and darker cream flowers.

I'm afraid that I am unable to help you with this. I was unaware of M. hermosana until about a year before it was described. It was only then that I understood that it had been circulating in Germany under the name of M. schrottii. I think it probably was a nomen nudum, and not properly described. But that's only my supposition! I'd never seen it on any seed lists I used, mainly from the Czech Republic, but also a few from Germany.

I would suggest it is M. compressa ssp. centralifera.

looks more like M. compressa to me.

Nice sequence of young plants! Now that the days here in the UK are getting longer, my thoughts are going to the task of repotting. I have a fair number of seedlings as well as perhaps a few hundred larger plants in desperate need of more root space.
However, as I keep my greenhouse between 4 & 5C, I'd have to use very dry compost so I'll wait a bit longer until daytime reaches a sensible temperature!

Once the cactus bug bites its very difficult to stop adding just one more plant!
Welcome and enjoy.

Great, well done, you;ve cracked the image hosting then.

I don't have any direct experience of growing cacti indoors, though I started a thread on the BCSS Forum in 2016, though this was initially aimed at propagation of seeds. It does seem to have resurfaced and now seems to be a rather technical discussion about things what I know not of!!
A friend of mine used to over-winter his plants in a spare bedroom, but as that was when the plants were dormant, light levels weren't too much of an issue. When they started to grow he put them outdoors, without any greenhouse. It did mean a shorter growing season for him, and occasional losses when there were unseasonable frosts in late Spring, but this was in Belgium, so probably not the sort of temperature swings that you might have in Denver.
Will your plants just be in a spare room? As I have no real experience, I'd probably start with led lights at about double or treble the usual domestic lighting level, and see how they go.
Hopefully others here will have more knowledge than me.
Btw what is a Geezer Farm? I guess a retirement home of some kind?

Yes, I'd agree, definitely one of the viidiflorus group at least.

Glad to have you back! A bit colder at this time of year I'd think than New Mexico!

Great little plants! I like the one with central spines especially.

Yes, I have reported them, it was 2009 when I had them from Hugo, and straight into 2 3/4 inch pots. Now in 4inch. So I think a stray seed of similar if not quite identical species, one into each pot is unlikely, and I never reuse potting compost, and always wash each pot in hot soapy water to re-use.

Hi Agrippa,
I did wonder if somehow a seed had gone adrift, but when I repotted, the different head did appear to come out of the lower part f the main head body, quite low. I appeared to have grown some of its own roots as well. If it had been a stray seed, then I'd want to know why these two specific plants, when there were other plants around them, and also they were nowhere near where my magnimamm/compressa plants are situated, and the distance between is about 30 ft. I'm not aware of having had any birds in the greenhouse, nor any streams of ants. I can't really imagine what other seed disseminating insects there might be.
If and when I get some information from where they originally came from, I'll let you all know.

Excellent and so good to see in this dull winter weather.
Happy New Year,
Chris
