Help with ID Please

[Duns]

The plants in the images below are the last unidentified plants I have from my recently purchased batch. Can anyone help with their identification?
Many thanks,
John

I may not be exactly correct here, but these are something like:
1. Echeveria derenbergii
2. x. Graptosedum - maybe "Vera Higgins" in need of slightly more light
3. Aloe perfoliata

I have entirely different identifications, I'm afraid, although the geni are the same
1) Echeveria chihuahuaensis
2) Graptosedum 'Francisco Baldi'
3) Aloe x nobilis

... the geni are the same

Hi Liz,

FYI, genus is a third declension latin noun so its plural is genera not geni
cf equus (horse) which is second declension and the plural is indeed equi.

PS As a scientist, my 'O-level latin' has been with me throughout my working life! Sad, really!

Thank you very much ESP and Liz for taking the time to ID my plants - it is really helpful and much appreciated.

Hi Tony, thank you for clarifying that, I felt when I wrote it it was probably wrong. Unfortunately, I did not have the benefit of Latin at school, I often wish I had.
Hi Duns, I hope we were not entirely useless in identifying your plants, it can be a minefield and we don't even have the excuse of blurred, badly lit photos.

[Duns]

Not at all Liz. The IDs from you and ESP have pointed me in the right direction and I can now utilize online resources to form a view. I am a complete novice and the help is very much appreciated. I am pleased to say my knowledge of genera (I am learning latin as well!!) is improving though species is a whole different ball game.

Many thanks again

I'd agree with Liz regarding Aloe x nobilis, but wondered about Echeveria pulidonis as an alternative possibility for the first one.

[Liz M]

Hi Mike, this is a picture of my Echeveria pulidonis. To me it is quite different from the original picture, as the leaves on that have a very distinctive point and the dark edging is only present at the point. However, mine has had continuous sun over the growing season and is a large plant of many rosettes, also the centre of the rosettes is very tight and the whole rosette is tightly curved inward, with very blue rosettes. This is a major difference to the one pictured. It could be down to cultivation practice, though, I agree. I do have a very small one and it exhibits the same characteristics as the large plant, so I leave it there.

Nice plant, Liz.
It was the leaf tip colouring that made me think of pulidonis, plus it's mass propagated in the trade. Amount of colour on the leaf edges can vary between clones, and also will tend to be less if the plant's had less direct sun. It's always a bit harder with a small plant and not knowing the growing conditions.
