Identification: Please Help in Identifying some cactus and succulents

Sorry, got quite a number of them. Thanks for your time!

Plant #1: Euphorbia aeruginosa (Picture 1-2)
Plant #2: Haworthia cymbiformis (Picture 3-4)
Plant #3: Frithia pulchra (Picture 7-8)
Plant #4: Mammillaria scheinvariana (Picture 5-6)
Plant #5: Pleiospilos nelii - "Split Rock Plant" (Picture 9)
Plant #6: Gasteria marmorata (Picture 10-11)
Plant #7: Crassula perforata "String of Buttons" (Picture 12-13)
Plant #8: Sempervivum 'Oddity' (Picture 14-15)

 

The pics are rather blurry, you are obviously holding the camera too close to the plants, but I can give you a hint:

2: Haworthia
3: Fenestraria
4: Mammillaria
5: Pleiospilos (nelii, I think)

(I don't know much about these genera and the other non-cactus succulents, but I am sure that others will fill in some of the blanks soon.)

 

#3: "Fenestraria is a monotypic genus of succulent plants in the family Aizoaceae. The species is also called babies toes or window plant. On each leaf there is transparent window-like area at the top, it is for these window-like structures that the genus is named (Latin: fenestra). "

Read from wiki, but this plant don't have those "windows-like feature". Is it a hybrid or is there some other species that look like them?

#5: Yep, thank you very much, it is Pleiospilos nelii - "Split Rock Plant"

#4: It has hooks and soft white thingy.

#2: Haworthia, it's a one big family..

Anyway thanks for helping to identify.

 

The windows are not always easy to see, a sharper photo is necessary to determine if they are present (at least for me). There are other plants that resembles it, but those I know of have windows too ...

 

1 Euphorbia aeruginosa
2 possibly Haworthia cymbiformis
after pleispilosis is:
Gasteria marmorata or possibly G. verrucosa
Crassula (perforata?)
and lastly I think is a Sempervivum sp.

 

Thanks you very much for your help.

I went to check and confirm

#1: Euphorbia aeruginosa
#2: Haworthia cymbiformis
#6: Gasteria marmorata
#7: Crassula perforata "String of Buttons"
#8: Sempervivum 'Oddity'

 

Plant #3: I think it is a Mammillaria scheinvariana

Plant #4: I don't see any windows at the top of the plants, the difference on the top of the plant is that it is glossy, transparent and shiny looking. It's not really that clear like the Fenestraria. It is possible to be Frithia pulchra?

 

I think you may be right with Frithia pulchra on the last one.

 

It is very easy to distinguish between a Fenestraria and a Frithia, the windows of the latter feels like sandpaper, while the Fenestraria windows are smooth, shiny and slightly triangular. They are relatively similar regarding colour and transparency, however. I looked at my plant, and it seems to change with age too, older Fenestraria windows look less transparent.

 

Thanks for sharing your knowledge. I didn't know one can differentitate them by feeling them.

I guess it is a Frithia, the windows feel rough to me.
It is glossy but it is not triangular, more circular like the individual "stems" (Are they call stems?)
About the age, I'm not so sure as I've just purchased it from a hyper-market. Sadly, none of the plants are labeled there and the people there doesn't know much about them except for the cost of it.

 

Here is a close-up of a Frithia (upper) and Fenestraria (lower).
I would call them leaves, that is what they really are.
BTW, this is no, 3 and the Mammillaria no. 4 in you list, right?

 

Thanks for the close up view of the leaves. I can confirm it is Frithia. Thanks for your help!

Picture 5 and 6 is for Plant #3, so Mammillaria is Plant #4 on the list. Sorry for the typo
