Another seedling species to identify

Me again,

Somehow when transferring these 6 seedlings from their group pot; I lost the tag.  The other 2 are M. perezdelarosae.

Any thoughts on it's ID?    It has not flowered so far.  Each pot contains one plant.  

Thanks again!

Best regards, Lisa

I think that this could be M. rekoi, as it has a hooked central spine, on some areoles at least.

Thanks Chris,

Ok, more time and a flower is needed on this one. I have a list of seeds sown at the time I planted this batch and rekoi wasn't on the list; but that doesn't mean it isn't that species.

Best regards, Lisa

Lisa,  М. mainiae in bloom. in maynouf .

Hi Vladimir-

You think this is M. mainiae?

Best regards, Lisa

Lisa! ...and a flower is needed on this one. I have a list of seeds...  
We look forward to the support of the hall. I'm not a pro. At first glance, I thought of zephyranthoides, then about odorata. Most of all, I was wrong.  List publish! Vladimir.

I was embarrassed shiny, cone Mamil. Another option - duoformis: xuchiapensis or erythrocalyx.
All. Not anymore. Vladimir.

Lisa, I first wrote all those verbal adjectives which came to mind at first, and then erased. ( too clear for modesty dangerous ). Disaster! Like an avalanche from the mountains. The horror! The film is quite a dangerous thing. 116 of the elbows is a very large sail. Over the summer sags, you need to pull up constantly. I fell for a similar trick 15 years ago. In February it snows, and then on top of pouring rain. The film is torn - on the tables, cacti knee-deep in water. And the rake again once in 5-6 years. Well, like all other people. And in April of the film flying around the suburbs. In October all the same, only in reverse. I had to buy polycarbonate. 5 years good. Let's wait and see. I have a 1/5 of Your greenhouse. A quarter of the tunnel in August the sack. I live on the pavement. Morning dew has not seen for 20 years.
Vladimir.
PS Melocactus You have already grown up.
 Last winter the snow helped me.

Hi Vladimir-

My Mammillaria shelf disaster has a happy ending. It only took me about 4 hours to clean up the mess.

When I was inspecting each plant for damage; I realized what a wonderful genus Mammillaria is.

So.... I decided to get more plants. But, I already had most everything I could find in the US - so I ordered a fair amount of seed. And now.... I have a very nice Mammillaria collection.

Best regards, Lisa

I know several people who keep their plants in a poly-tunnel, but now I understand why they don't have any shelves!
I'm glad that you managed to salvage so many, and then to add more. I'm moving house soon, I hope, but I shall stay with glass!

Shelves I hung the jumpers and even more pressed to the ground construction of greenhouses. They are set for winter and reduce the passage.
He returned from the greenhouse to the house, and on the back beloved cardigan clutched all the seedlings m. yaqensis.
PS. let's move on to another topic.
