Echeveria nodulosa (Baker) Ed.Otto is the correct and accepted scientific name for this species of Echeveria. It was named and described as such by Carlos Frederico Eduardo Otto in Hamburger Garten- Blumenzeitung in 1873. It was first named Cotyledon nodulosa by John Gilbert Baker in Refugium Botanicum in 1869.
MANY websites and databases, actually MOST OF THEM, say the correct scientific name is Echeveria nodulosa (Baker) Otto. As you can see, the author’s name is different… This would mean the plant was named and described as such by Christoph Friedrich Otto. BUT, The publication cited where the plant was named and described is always Hamburger Garten- Blumenzeitung in 1873.
While there is barely anything online about Carlos Frederico Eduardo Otto, The Biodiversity Heritage Library says C. F. Otto is the father of Carlos… Christoph Friedrich Otto was born in 1753 and died in 1856 before the plant was named and described in 1873. Carlos Frederico Eduardo Otto was born in 1812 and died in 1885. SO, no doubt, the Echeveria nodulosa was named and described by Carlos Frederico Eduardo Otto (Ed.Otto) instead of Christoph Friedrich Otto (Otto).
Although The Plant List (no longer maintained) says the correct and accepted name is Echeveria nodulosa (Baker) Otto, the link it gives to The International Plant Names Index (IPNI) says Echeveria nodulosa (Baker) Ed.Otto…
There are a few cases where a botanist had unpublished books where he named a few new plants. The publications were published after their death and they still received credit for naming the plants. I don’t believe that is the case here. Someone just made an error and others followed.
I bought my Echeveria nodulosa from Mast’s Greenhouse in the spring of 2016. It was really neat and I never had an Echeveria quite like this one. I was doing some experimenting with succulents in one of my beds, so I put this Echeveria in the ground, pot and all, in the bed behind the foundation of my grandparent’s old house. This may have been OK except for one thing… The Marigold ‘Brocade’ decided to take over while I got busy with other things. I basically forgot about the two Echeveria I had put in the bed and when I remembered, the bugs had all but destroyed them. You would think the smell of the Marigolds would have deterred the bugs. Anyway, I took the pots up and put them on the plant tables with the other succulents. When cooler temps came, I took the potted plants inside. Unfortunately, my Echeveria nodulosa never fully recovered and didn’t make it through the winter.
