Differences between Ech Harmsii and Ech Set-Oliver?

I have two plants, one labelled as Ech Harmsii (left) and one labelled Ech Set-Oliver (right).
Can anyone tell me if the labels look to be correct?
Also can anyone tell me the differences between the two plants apart from slightly larger corolla and stems on Harmsii?
Thanks Sharon

Hi,

The answer will be in the flowers.
For the moment, I don't see E. harmsii on the photo, you can possibly show the same plant...
E. harmsii is « minutely puberulent » : hairs are 0,2 mm. long.

Would this be Harmsii? what is the difference between Harmsii and Spruce-Oliver please?
Thanks again for your help

Echeveria Set-Oliver is the cross of a hairy species and a puberulent species, which means that the hybrid is a hairy plant.
The last photo shows a plant with hairs. As Tom already explained, you cannot see such hairs on E. harmsii. Therefore also this one is not harmsii. To identify it flowers would be decisive.
The two plants on your first photo look very similar.

The last plant looks like 'Spruce-Oliver' but... without flowers for the moment.

Hi Tom,
that's what I thought, but am still confused as to what Harmsii looks like close up, is there anyone that can provide a photo so I can understand the differences between Harmsii and the plants in my photos?
The photos on crassulaceae are hard for a newbie to relate to a real plant as they are small and not close-up enough for my eyes.
Also if you google images there are 1001 versions of Harmsii, but I have not found one that I would believe
I do not have Walther's book so cannot read up what it says,
thanks again for all the input,
Sharon

Google is not a reference... so many plants are erroneously named.
Look at the description with photos, here ; the pubescence is very minute, E. harmsii is more velvety than hairy.

Hi,

if you have a magnifying glass, than take a closer look at the hairs. In Echeveria harmsii, and related species, they are very short and consist at least of two cells. All plants that named harmsii with longer and multicellular hairs are no Echeveria harmsii.

Thanks again, my magnifying glass wasn't that good, but I will search for a better one.
In the meantime I found better photos at http://crassulaceae.net/echeveriamenu/9 … h-i-j-k-uk
cheers

The old as well as the new site have a Search function. So you can easily find correct descriptions and photos of the plants you would like to know more about.
