[Arash37]

Hello. Could you guys help with ID? I have guesses about some plants, but i don't know about some.

1. Mammillaria plumosa ??


2. Mammilaria gracilis 'Arizona Snowcap' ??


3. Rhipsalis ??


4. Mammillaria hahniana ??


5. I don't know what could it be


6. Mammillaria but what species ??


7. Parodia warasii ??


8. Mamillaria ??

1 Mammillaria/Krainzia guelzowiana
2 Mammillaria gracilis Oruga
3 Rhipsalis cereuscula
4 OK
5 Notocactus uebelmannianus
6 Mammillaria marksiana
7 Eriocactus magnificus
8 Mammillaria haageana

Number 1 could also be Mammillaria albicoma, but hard to tell from the photo, but seems hairier to me than M. guelzowiana. However flowers would sort it out as M. albicoma has M. bocasana type small white flowers, whilst M. guelzowiana large pink ones. Rest I agree with Anttisepp

Number 1 appears to me to have red hooked central spines. Doesn't that suggest M. guelzowiana?

My guess is that #4 could also be said to be Mammillaria hahniana v. woodsii.

[DaveW]

You could be right loyall. If so it is a more hairy form than the average M. guelzowiana's, maybe a selected hairier clone, but there are some more hairy ones here.

M. guelzowiana (currently classified as Cochemiea guelzowiana; you might want to add Cochemiea to the list of genus names, anttisepp!) can have gold-colored spines too. See these soon to be 2 year old seedlings of field number SB 1160, a mix of gold and red central spines on different plants.


I do think #1 looks more like one of the woollier forms of M. bocasana, like 'multilanata' or 'splendens'.

[DaveW]

Also the variation of how long the hooked central spines can be in relation to the amount of wool.

Thank you all for your suggestions. About no. 8 found also really similar species, Mammillaria perbella and now wonder between 3 plants: M. perbella, M. formosa subs. microthele var. superfina and and M. haageana. My speciman has 0-1 central spines. Llifle says that M. perbella has 0-1, 2 or 4 spines. M. haageana has usually 2 but variable from 0 to 6 and there is no info about central spines if we are talking about M. formosa subs. microthele var. superfina.

Agree with anttisepp about M.haageana. Both perbella and formosa at that age are globose with flattened apex. Your plant is elongated, which is more often with young haageana (yours could be M.haageana ssp.elegans). Flowers could help to narrow it down.
