It is amazing how many cactus are out there without a name. I'v bought many my self. Here are my best guesses. 1 Stenocactus multicostatus 2 Mammillaria bocasana 3 Mammillaria. comptotricha 4 Parodia scopa ? 5 Gymnocalycium ? 6 Mammillaria 7 Mammillaria 8 Melocactus 9 Coryphantha andreae ? 10 Parodia All these should have a question mark behind them. I'm a long way from being the last word on cactus I.D.s.

Hello, sorry can't ID as I don't grow these cacti. EL gives sound info above. As the first cactus is a tall one as opposed to a barrel shaped one, could I suggest that the best mix for both it and the other, would be a mix of thirds using c/smix, perlite and horticultural/alpine gravel. You can get small bags of each of these from B & Q for around £3 each. Make sure you either wash the perlite thoroughly in a sieve or just seive it downwind, don't breath the dust in. B&Q perlite is rather dusty, mine is, so there is a lot of waste, just use the largest particles you gain from using your very best kitchen seive! I've also used Wilko perlite, that wasn't quite as bad. Wilko may not sell it now it's Nov, B&Q or garden centres may be a better bet for all the ingredients at this time of the year. The gravel will give the plants much more stability, especially the tall one. Don't get vermiculite if no perlite, it's too water retentive. Aquarium gravel or chicken grit with no shell can also substitute for the hort/alpine gravel. Repotting into a better mix will get rid of any bugs that you think you may have there and it will also solve the problem that you almost certainly would be asking us about in the not to distant future "why are my cacti dying?"... which would be due to the wrong soil they were sold in! So, to prevent that from happening you need to make sure all the old mix is removed, use a chopstick, pencil or similar to get rid of it all. If it won't come if with poking and shaking, swish in water, keep bases of plants dry though, let the roots air dry on kitchen paper, plant when dry. Hold the cactus in a wrap of newspaper or bubble wrap to protect your hands. Moisten the mix and replant, not soaking wet, just moist and crumbly. Won't need much water anyway now weather is colder. Shout if you need any more help. Gill

ktrayn It is actually better to make 1 thread with plants to ID - too many individual threads on same subject (ID) just clutter up the forum. Just number the plants if few in the same photo, or if 1plant/photo - number photos, and it will be just fine :) Do not worry about this post, at least you can see how fast, sometimes, you get the answer :):):) Most plants I bought that came from Altmans did have labels. It is the grower that supplies the labels, not the seller (HD, Lowes, or any garden center). So if there is no label, it is grower not the store - unless they had only stick-in plastic tags that get lost, and/or misplaced by ppl pulling them out to check and not putting them back where they came from. And there are some mistakes too, sometimes grower will put wrong label on whole bunch of plants....Some growers use only common names and that could create problems since some common names are used for few different plants. Best for everyone to learn botanical/scientific name.
